Remarks

The AMQPClassic class provides an easy-to-use AMQP 0.9.1 client implementation, and it also supports certain RabbitMQ extensions to the AMQP 0.9.1 specification. The class supports both plaintext and TLS-enabled connections over TCP.

Connecting

The AMQP 0.9.1 transport protocol has two layers: an overall connection between the client and server, and one or more channels running over that connection.

The class implements both layers, so the first step is to initiate the overall connection. Set the AuthScheme, User, Password, SSLEnabled, and VirtualHost properties if necessary, then call the ConnectTo method, passing it the server's hostname and port number. (If the server in question is not running RabbitMQ, disabling the RabbitMQCompatible configuration setting before connecting is also recommended.)

The next step is to create at least one channel, which can be accomplished by using the CreateChannel method. The class allows creating any number of channels, up to the limit specified by the MaxChannelCount configuration setting.

Connecting and Creating a Channel // The examples in this documentation use a RabbitMQ server, which requires SASL Plain auth. amqpc1.AuthScheme = AmqpclassicAuthSchemes.smSASLPlain; amqpc1.User = "guest"; amqpc1.Password = "guest"; amqpc1.SSLEnabled = true; amqpc1.ConnectTo("amqpclassic.test-server.com", 5671); amqpc1.CreateChannel("channel");

Once the class has connected to the server, and one or more channels have been opened, the class can begin manipulating exchanges and queues, publishing messages, and creating consumers.

Note that most AMQP 0.9.1 operations can themselves vary in their complexity. The examples below are intentionally simple for the sake of clarity and brevity, but links are provided for many other parts of the class's API where more detail can be found.

Declaring Exchanges

The DeclareExchange method is used to declare (i.e., create, or verify the existence of) exchanges on the server. While all AMQP servers provide a default, direct-type exchange that all queues are bound to automatically (using their name as the routing key), more complex use-cases will often require creating additional exchanges of varying types.

Declaring an Exchange // Declare a direct-type exchange. amqpc1.DeclareExchange("channel", "MyExchange", "direct", false, false, false, false);

Exchanges can also be deleted using the DeleteExchange method.

Declaring Queues

The DeclareQueue method is used to declare (i.e., create, or verify the existence of) queues on the server. Unlike with exchanges, the server does not provide any queues by default, so declaring a queue is always necessary (unless one has already been created by another client, or configured ahead-of-time on the server itself).

Declaring a Queue // Declare a queue. amqpc1.DeclareQueue("channel", "MyQueue", false, false, false, false, false);

Queues may also be deleted or purged using the DeleteQueue and PurgeQueue methods.

Binding Queues to Exchanges

The BindQueue method is used to bind a queue to an exchange. Exchanges use the information held by their queue bindings to determine which messages to forward to which queues.

Note that all AMQP 0.9.1 servers automatically bind all queues to their default exchange (which is always a direct exchange with no name) using each queue's name as the binding's routing key. This makes it easy to send a message to a specific queue without having to declare bindings; just call PublishMessage, pass empty string for ExchangeName, and the name of the desired queue for RoutingKey.

Binding a Queue to an Exchange // Bind a queue to an exchange. Messages will only be delivered to the queue if their routing key is "MyRoutingKey". amqpc1.BindQueue("channel", "MyQueue", "MyExchange", "MyRoutingKey", false);

Queues can also be unbound from exchanges using the UnbindQueue method.

Publishing Messages

To publish a message, populate the Message* properties, and then call the PublishMessage method.

Publishing a Message amqpc1.Message.Body = "Hello, world!"; // Publish a message to the server's default (no-name) exchange, using the name of a specific queue as the routing key. amqpc1.PublishMessage("channel", "", "MyQueue", false, false); // Publish a message to the "MyExchange" exchange, using the routing key "MyRoutingKey". amqpc1.PublishMessage("channel", "MyExchange", "MyRoutingKey", false, false);

Note that outgoing messages may be handled differently by the server if the channel they are sent over is in transaction or (for RabbitMQ only) "publish confirmations" mode. Refer to the EnableTransactionMode and EnablePublishConfirms methods for more information.

Receiving Messages

There are two possible ways for the class to receive a message:

  • Messages can be asynchronously pushed to the class from the server. At any point in time, the server may push a message to the class from a queue that the Consume method has been used to attach a consumer to.
  • Messages can be synchronously pulled from the server by the class. The FetchMessage method is used to attempt to pull (or "fetch") messages from a specific queue.

Regardless of how they are received, all incoming messages cause the ReceivedMessage* properties to be populated and the MessageIn event to fire.

Receiving a Message // MessageIn event handler. amqpc1.OnMessageIn += (s, e) => { if (e.MessageCount == -1) { // The server pushed a message to us asynchronously due to a consumer we created. Console.WriteLine("The server pushed this message to us via consumer '" + e.ConsumerTag + "':"); Console.WriteLine(amqpc1.ReceivedMessage.Body); } else if (e.DeliveryTag > 0) { // We pulled a message from a queue with the FetchMessage() method. Console.WriteLine("Message successfully pulled:"); Console.WriteLine(amqpc1.ReceivedMessage.Body); Console.WriteLine(e.MessageCount + " messages are still available to pull."); } else { // We tried to pull a message, but there were none available to pull. Console.WriteLine("No messages available to pull."); } }; // Attach a consumer to "MyQueue". amqpc1.Consume("channel", "MyQueue", "consumerTag", false, true, false, false); // Or, try to fetch a message from "MyQueue". amqpc1.FetchMessage("channel", "MyQueue", true);

Note that the MessageIn event always fires if FetchMessage is called successfully, even if there were no messages available to fetch; refer to MessageIn for more information.

Procedural Interface


ipworksmq_amqpclassic_get($res, 7 , $channelindex);


Default Value

true

Remarks

Whether the channel is currently accepting new messages from the server.

This property is read-only and not available at design time.

Data Type

Boolean

ChannelMode Property (IPWorksMQ_AMQPClassic Class)

What mode the channel is operating in.

Object Oriented Interface


public function getChannelMode($channelindex);


Procedural Interface


ipworksmq_amqpclassic_get($res, 8 , $channelindex);


Default Value

0

Remarks

What mode the channel is operating in.

This property reflects what mode the channel is operating in. Possible values are:

  • cmtNormal (0 - default): Normal mode.
  • cmtTransactional (1): Transaction mode.
  • cmtPublishConfirms (2): Publish confirmations mode.

All channels are in normal mode when they are created; there's nothing special about a channel in normal mode.

Channels can be put in transaction mode using the EnableTransactionMode method. While a channel is in transaction mode, all messages published and acknowledgements sent over it will be part of a transaction, and the server will wait to process them until the transaction is either committed or rolled back.

Channels can be put in publish confirmations mode using the EnablePublishConfirms method. While a channel is in publish confirmations mode, the server will acknowledge each message published by the class. The class will wait to fire the MessageOut event until it receives this acknowledgement. (Note that this mode is only available when the RabbitMQCompatible configuration setting is enabled.)

23 (cstPKCS11)The certificate is present on a physical security key accessible via a PKCS11 interface.

To use a security key the necessary data must first be collected using the CertMgr class. The ListStoreCertificates method may be called after setting CertStoreType to cstPKCS11, CertStorePassword to the PIN, and CertStore to the full path of the PKCS11 dll. The certificate information returned in the CertList event's CertEncoded parameter may be saved for later use.

When using a certificate, pass the previously saved security key information as the SSLCertStore and set SSLCertStorePassword to the PIN.

Code Example: SSH Authentication with Security Key certmgr.CertStoreType = CertStoreTypes.cstPKCS11; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; //PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);

99 (cstAuto)The store type is automatically detected from the input data. This setting may be used with both public and private keys and can detect any of the supported formats automatically.

If a matching certificate is found, the property is set to the full subject of the matching certificate.

If an exact match is not found, the store is searched for subjects containing the value of the property.

If a match is still not found, the property is set to an empty string, and no certificate is selected.

The special value "*" picks a random certificate in the certificate store.

The certificate subject is a comma separated list of distinguished name fields and values. For instance "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are displayed below.

FieldMeaning
CNCommon Name. This is commonly a host name like www.server.com.
OOrganization

SSLEnabled Property (IPWorksMQ_AMQPClassic Class)

Whether TLS/SSL is enabled.

Object Oriented Interface


public function getSSLEnabled();


public function setSSLEnabled($value);

Procedural Interface


ipworksmq_amqpclassic_get($res, 151 );


ipworksmq_amqpclassic_set($res, 151, $value );

Default Value

false

Remarks

This setting specifies whether TLS/SSL is enabled in the class. When False (default) the class operates in plaintext mode. When True TLS/SSL is enabled.

TLS/SSL may also be enabled by setting SSLStartMode. Setting SSLStartMode will automatically update this property value.

If the default port (5672) is selected when SSLEnabled is set to true, the port will automatically be changed to the default port for AMQP with SSL (5671). Likewise, if port 5671 is selected when SSLEnabled is set to false, the port will automatically be changed to the default port. If the port has been set to any value other than the default values, it will remain the same when the value of SSLEnabled changes.

This property is not available at design time.

Data Type

Boolean

SSLProvider Property (IPWorksMQ_AMQPClassic Class)

This specifies the SSL/TLS implementation to use.

Object Oriented Interface


public function getSSLProvider();


public function setSSLProvider($value);

Procedural Interface


ipworksmq_amqpclassic_get($res, 152 );


ipworksmq_amqpclassic_set($res, 152, $value );

Default Value

0

Remarks

This property specifies the SSL/TLS implementation to use. In most cases the default value of 0 (Automatic) is recommended and should not be changed. When set to 0 (Automatic) the class will select whether to use the platform implementation or the internal implementation depending on the operating system as well as the TLS version being used.

Possible values are:

0 (sslpAutomatic - default)Automatically selects the appropriate implementation.
1 (sslpPlatform) Uses the platform/system implementation.
2 (sslpInternal) Uses the internal implementation.
Additional Notes

In most cases using the default value (Automatic) is recommended. The class will select a provider depending on the current platform.

When Automatic is selected, on Windows the class will use the platform implementation. On Linux/macOS the class will use the internal implementation. When TLS 1.3 is enabled via SSLEnabledProtocols the internal implementation is used on all platforms.

Data Type

Integer

SSLServerCertEncoded Property (IPWorksMQ_AMQPClassic Class)

This is the certificate (PEM/base64 encoded).

Object Oriented Interface


public function getSSLServerCertEncoded();


Procedural Interface


ipworksmq_amqpclassic_get($res, 154 );


Default Value

''

Remarks

This is the certificate (PEM/base64 encoded). This property is used to assign a specific certificate. The SSLServerCertStore and SSLServerCertSubject properties also may be used to specify a certificate.

When SSLServerCertEncoded is set, a search is initiated in the current SSLServerCertStore for the private key of the certificate. If the key is found, SSLServerCertSubject is updated to reflect the full subject of the selected certificate; otherwise, SSLServerCertSubject is set to an empty string.

This property is read-only and not available at design time.

Data Type

Binary String

Timeout Property (IPWorksMQ_AMQPClassic Class)

A timeout for the class.

Object Oriented Interface


public function getTimeout();


public function setTimeout($value);

Procedural Interface


ipworksmq_amqpclassic_get($res, 181 );


ipworksmq_amqpclassic_set($res, 181, $value );

Default Value

60

Remarks

If the Timeout property is set to 0, all operations return immediately, potentially failing with a WOULDBLOCK error if data cannot be sent immediately.

If Timeout is set to a positive value, data is sent in a blocking manner and the class will wait for the operation to complete before returning control. The class will handle any potential WOULDBLOCK errors internally and automatically retry the operation for a maximum of Timeout seconds.

The class will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not "freeze" and remains responsive.

If Timeout expires, and the operation is not yet complete, the class fails with an error.

Please note that by default, all timeouts are inactivity timeouts, i.e. the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received.

The default value for the Timeout property is 60 seconds.

Data Type

Integer

Procedural Interface

ipworksmq_amqpclassic_do_bindqueue($res, $channelname, $queuename, $exchangename, $routingkey, $nowait);

Remarks

This method is used to bind the queue named QueueName to the exchange named ExchangeName. Exchanges use bindings to determine which queues to route messages to.

Multiple bindings between the same queue and exchange with different RoutingKeys and/or arguments are allowed; requests that would create a duplicate binding are ignored. No queue will ever receive duplicate copies of any message, regardless of what bindings are present on the server.

Note that all AMQP 0.9.1 servers automatically bind all queues to their default exchange (which is always a direct exchange with no name) using each queue's name as the binding's routing key. This makes it easy to send a message to a specific queue without having to declare bindings; just call PublishMessage, pass empty string for ExchangeName, and the name of the desired queue for RoutingKey.

ChannelName controls what channel the class will send the request over. While any channel can technically be used, keep in mind that the server will close it if a channel error occurs. For this reason, it is good practice to make requests such as this one using a channel that is not involved in message publishing or consumption.

QueueName must be a non-empty string consisting only of letters, digits, hyphens, underscores, periods, and colons. It must be no longer than 255 characters.

The server's default exchange may be specified by passing empty string for ExchangeName. Otherwise, ExchangeName must be a non-empty string consisting only of letters, digits, hyphens, underscores, periods, and colons. It must be no longer than 255 characters.

The RoutingKey parameter specifies the binding's routing key. Exchanges that use routing-key-based logic make some sort of comparison between the routing keys of incoming messages and this value to decide which messages should be forwarded to the specified queue. Examples of exchange types which use routing keys include:

  • direct exchanges, which compare (for equality) the routing keys of incoming messages to the routing keys of each queue bound to them.
  • topic exchanges, which match the routing keys of incoming messages against the routing pattern of each queue bound to them.

Not all exchange types make use of routing keys, in which case empty string can be passed for the RoutingKey parameter. Examples of exchange types which don't use routing keys include:

  • fanout exchanges simply forward incoming messages to all queues bound to them, unconditionally.
  • header exchanges only forward messages that include certain headers. When binding a queue to a header exchange, add items to the Argument* properties to describe the headers that eligible messages must have, and whether they must have any or all of those headers.

Note that the format of the RoutingKey parameter and/or the content of the Argument* properties may differ slightly between server implementations. Refer to your server's documentation to determine what it expects to receive for each exchange type that it supports.

The NoWait parameter, if True, will cause the server to execute the request asynchronously. For asynchronous request handling, the server only sends back a response in case of an error.

An exception is thrown if no channel with the given ChannelName exists, or if the server returns an error because:

  • No queue with the given QueueName exists.
  • No exchange with the given ExchangeName exists.

Note that in AMQP, server errors are grouped into "connection errors" and "channel errors", and both are fatal. That is, if the server returns a channel error, it will then close the channel which caused the error; and if it returns a connection error, it will then close the connection. The AMQPClassic class's Error Codes page includes AMQP's various connection and channel errors.

CancelConsume Method (IPWorksMQ_AMQPClassic Class)

Cancels an existing consumer.

Object Oriented Interface

public function doCancelConsume($channelname, $consumertag, $nowait);

Procedural Interface

ipworksmq_amqpclassic_do_cancelconsume($res, $channelname, $consumertag, $nowait);

Remarks

This method requests that the server cancel the consumer identified by the given ConsumerTag on the channel specified by ChannelName.

The NoWait parameter, if True, will cause the server to execute the request asynchronously. For asynchronous request handling, the server only sends back a response in case of an error.

An exception is thrown if no channel with the given ChannelName exists, or if the server returns an error because no consumer with the given ConsumerTag exists.

Note that in AMQP, server errors are grouped into "connection errors" and "channel errors", and both are fatal. That is, if the server returns a channel error, it will then close the channel which caused the error; and if it returns a connection error, it will then close the connection. The AMQPClassic class's Error Codes page includes AMQP's various connection and channel errors.

CloseChannel Method (IPWorksMQ_AMQPClassic Class)

Closes a channel.

Object Oriented Interface

public function doCloseChannel($channelname);

Procedural Interface

ipworksmq_amqpclassic_do_closechannel($res, $channelname);

Remarks

This method closes the channel named ChannelName and removes it from the Channel* properties.

If no channel with the given ChannelName exists, an exception will be thrown.

CommitTransaction Method (IPWorksMQ_AMQPClassic Class)

Commits the current transaction for a channel.

Object Oriented Interface

public function doCommitTransaction($channelname);

Procedural Interface

ipworksmq_amqpclassic_do_committransaction($res, $channelname);

Remarks

This method commits the current transaction for the channel with the given ChannelName. A new transaction is started immediately after the current one is committed.

Refer to EnableTransactionMode for more information about transactions.

An exception is thrown if a channel with the given ChannelName doesn't exist, or if the server returns an error because the channel does not have transaction mode enabled.

Note that in AMQP, server errors are grouped into "connection errors" and "channel errors", and both are fatal. That is, if the server returns a channel error, it will then close the channel which caused the error; and if it returns a connection error, it will then close the connection. The AMQPClassic class's Error Codes page includes AMQP's various connection and channel errors.

Config Method (IPWorksMQ_AMQPClassic Class)

Sets or retrieves a configuration setting.

Object Oriented Interface

public function doConfig($configurationstring);

Procedural Interface

ipworksmq_amqpclassic_do_config($res, $configurationstring);

Remarks

Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

Connect Method (IPWorksMQ_AMQPClassic Class)

This method connects to a remote host.

Object Oriented Interface

public function doConnect();

Procedural Interface

ipworksmq_amqpclassic_do_connect($res);

Remarks

This method connects to the remote host specified by RemoteHost and RemotePort. For instance: component.RemoteHost = "MyHostNameOrIP"; component.RemotePort = 7777; component.Connect();

ConnectTo Method (IPWorksMQ_AMQPClassic Class)

This method connects to a remote host.

Object Oriented Interface

public function doConnectTo($host, $port);

Procedural Interface

ipworksmq_amqpclassic_do_connectto($res, $host, $port);

Remarks

This method connects to the remote host specified by the Host and Port parameters. For instance: component.ConnectTo("MyHostNameOrIP", 777)

Consume Method (IPWorksMQ_AMQPClassic Class)

Starts a new consumer for a given queue.

Object Oriented Interface

public function doConsume($channelname, $queuename, $consumertag, $nolocal, $noack, $exclusive, $nowait);

Procedural Interface

ipworksmq_amqpclassic_do_consume($res, $channelname, $queuename, $consumertag, $nolocal, $noack, $exclusive, $nowait);

Remarks

This method instructs the server to start a new consumer on the queue named QueueName; once the consumer is created, it will cause messages enqueued to the specified queue to be delivered to the class over the channel specified by ChannelName.

Consumers last as long as the channel they were created on, or until they are cancelled using the CancelConsume method. Each time a message is delivered to the class, it is immediately added to the IncomingMessage* properties, the ReceivedMessage* properties are populated, and the MessageIn event fires.

ConsumerTag is a string which uniquely identifies the new consumer on the specified channel. If empty string is passed for ConsumerTag, the server will generate a consumer tag automatically when it creates the . this auto-generated consumer tag can then be retrieved by querying the ConsumerTag configuration setting after this method returns.

The NoLocal parameter, if True, ensures that the consumer never consumes messages published on the same channel. (Note that this functionality is not available on RabbitMQ servers, which ignore the NoLocal parameter).

The NoAck parameter controls whether the server will expect the class to acknowledge the each message delivered. Refer to MessageIn for more information about acknowledging messages.

The Exclusive parameter, if True, will cause the class to request that the server create an exclusive consumer. Attaching an exclusive consumer to a queue prevents any other consumers from consuming messages from that queue.

The NoWait parameter, if True, will cause the server to execute the request asynchronously. For asynchronous request handling, the server only sends back a response in case of an error.

Additional arguments may be sent with this request by adding them to the Argument* properties. Arguments are server-dependent; refer to your server's documentation to determine if any additional arguments apply for this request.

An exception is thrown if no channel with the given ChannelName exists, or if the server returns an error because:

  • No queue with the given QueueName exists.
  • The given ConsumerTag is already in use on the specified channel.
  • An exclusive consumer was requested for a queue which already has consumers attached to it.

Note that in AMQP, server errors are grouped into "connection errors" and "channel errors", and both are fatal. That is, if the server returns a channel error, it will then close the channel which caused the error; and if it returns a connection error, it will then close the connection. The AMQPClassic class's Error Codes page includes AMQP's various connection and channel errors.

Receiving a Message // MessageIn event handler. amqpc1.OnMessageIn += (s, e) => { if (e.MessageCount == -1) { // The server pushed a message to us asynchronously due to a consumer we created. Console.WriteLine("The server pushed this message to us via consumer '" + e.ConsumerTag + "':"); Console.WriteLine(amqpc1.ReceivedMessage.Body); } else if (e.DeliveryTag > 0) { // We pulled a message from a queue with the FetchMessage() method. Console.WriteLine("Message successfully pulled:"); Console.WriteLine(amqpc1.ReceivedMessage.Body); Console.WriteLine(e.MessageCount + " messages are still available to pull."); } else { // We tried to pull a message, but there were none available to pull. Console.WriteLine("No messages available to pull."); } }; // Attach a consumer to "MyQueue". amqpc1.Consume("channel", "MyQueue", "consumerTag", false, true, false, false); // Or, try to fetch a message from "MyQueue". amqpc1.FetchMessage("channel", "MyQueue", true);

CreateChannel Method (IPWorksMQ_AMQPClassic Class)

Creates a new channel.

Object Oriented Interface

public function doCreateChannel($channelname);

Procedural Interface

ipworksmq_amqpclassic_do_createchannel($res, $channelname);

Remarks

This method creates a new channel with the name ChannelName and adds it to the Channel* properties. If a channel with the given ChannelName already exists, an error will be thrown.

Connecting and Creating a Channel // The examples in this documentation use a RabbitMQ server, which requires SASL Plain auth. amqpc1.AuthScheme = AmqpclassicAuthSchemes.smSASLPlain; amqpc1.User = "guest"; amqpc1.Password = "guest"; amqpc1.SSLEnabled = true; amqpc1.ConnectTo("amqpclassic.test-server.com", 5671); amqpc1.CreateChannel("channel");

DeclareExchange Method (IPWorksMQ_AMQPClassic Class)

Verifies that an exchange exists, potentially creating it if necessary.

Object Oriented Interface

public function doDeclareExchange($channelname, $exchangename, $exchangetype, $passive, $durable, $autodelete, $nowait);

Procedural Interface

ipworksmq_amqpclassic_do_declareexchange($res, $channelname, $exchangename, $exchangetype, $passive, $durable, $autodelete, $nowait);

Remarks

This method is used to verify that an exchange named ExchangeName exists; and potentially creates it if no such exchange exists.

ChannelName controls what channel the class will send the request over. While any channel can technically be used, keep in mind that the server will close it if a channel error occurs. For this reason, it is good practice to make requests such as this one using a channel that is not involved in message publishing or consumption.

ExchangeName must be a non-empty string consisting only of letters, digits, hyphens, underscores, periods, and colons. It must be no longer than 255 characters, and must not begin with amq. unless the Passive parameter is True.

ExchangeType specifies the exchange type. All servers support the direct and fanout exchange types, and most should also support the topic and header exchange types. Some servers may support additional, custom exchange types as well. Refer to your server's documentation for more information about each exchange type, and to determine what exchange types it supports other than direct and fanout.

If Passive is True, the server will only verify that an exchange with the given ExchangeName actually exists (regardless of how it is configured).

If Passive is False, and no exchange named ExchangeName currently exists, the server will create one.

If Passive is False, and there is a preexisting exchange named ExchangeName, the server will verify that its current configuration matches the given parameters and arguments.

Durable specifies what happens to the exchange in the event of a server restart. Durable exchanges will be recreated, while non-durable (transient) exchanges will not.

AutoDelete specifies whether the server should automatically delete the exchange when all queues have been unbound from it. Note that this parameter is only sent if the RabbitMQCompatible configuration setting is enabled; it is ignored otherwise.

The NoWait parameter, if True, will cause the server to execute the request asynchronously. For asynchronous request handling, the server only sends back a response in case of an error.

Additional arguments may be sent with this request by adding them to the Argument* properties. Arguments are server-dependent; refer to your server's documentation to determine if any additional arguments apply for this request.

An exception is thrown if no channel with the given ChannelName exists, or if the server returns an error because:

  • One of the parameter constraints described above was violated.
  • One of the verification cases described above fails.
  • The value passed for ExchangeType did not correspond to an exchange type supported by the server.

Note that in AMQP, server errors are grouped into "connection errors" and "channel errors", and both are fatal. That is, if the server returns a channel error, it will then close the channel which caused the error; and if it returns a connection error, it will then close the connection. The AMQPClassic class's Error Codes page includes AMQP's various connection and channel errors.

Declaring an Exchange // Declare a direct-type exchange. amqpc1.DeclareExchange("channel", "MyExchange", "direct", false, false, false, false);

DeclareQueue Method (IPWorksMQ_AMQPClassic Class)

Verifies that a queue exists, potentially creating it if necessary.

Object Oriented Interface

public function doDeclareQueue($channelname, $queuename, $passive, $durable, $exclusive, $autodelete, $nowait);

Procedural Interface

ipworksmq_amqpclassic_do_declarequeue($res, $channelname, $queuename, $passive, $durable, $exclusive, $autodelete, $nowait);

Remarks

This method is used to verify that a queue named QueueName exists; and potentially creates it if no such queue exists.

After each successful call to this method, the class populates the QueueMessageCount property, as well as the QueueConsumerCount and QueueName configuration settings. Refer to each one for more information.

ChannelName controls what channel the class will send the request over. While any channel can technically be used, keep in mind that the server will close it if a channel error occurs. For this reason, it is good practice to make requests such as this one using a channel that is not involved in message publishing or consumption.

If creating a new queue, empty string can be passed for QueueName to have the server automatically generate a name for the new queue (which can then be retrieved using the QueueName configuration setting). In all other cases, QueueName must be a non-empty string consisting only of letters, digits, hyphens, underscores, periods, and colons. It must be no longer than 255 characters, and must not begin with amq. unless the Passive parameter is True.

If Passive is True, the server will only verify that a queue with the given QueueName actually exists (regardless of how it is configured).

If Passive is False, and no queue named QueueName currently exists, the server will create one.

If Passive is False, and there is a preexisting queue named QueueName, the server will verify that its current configuration matches the given parameters and arguments.

Durable specifies what happens to the queue in the event of a server restart. Durable queue will be recreated, while non-durable (transient) queue will not. (Note that the messages in durable queues will still be lost unless they are marked as persistent.)

Exclusive, if True, indicates that the queue may only be accessed by the current connection. Exclusive queues are deleted when the current connection closes.

AutoDelete specifies whether the server should automatically delete the queue when all consumers have finished using it. (Note that auto-delete queues aren't eligible for deletion until after a consumer attaches to them for the first time.)

The NoWait parameter, if True, will cause the server to execute the request asynchronously. For asynchronous request handling, the server only sends back a response in case of an error.

Additional arguments may be sent with this request by adding them to the Argument* properties. Arguments are server-dependent; refer to your server's documentation to determine if any additional arguments apply for this request.

An exception is thrown if no channel with the given ChannelName exists, if QueueName empty string and NoWait is True, or if the server returns an error because:

  • One of the parameter constraints described above was violated.
  • One of the verification cases described above fails.
  • An attempt was made to verify (i.e., the Passive parameter was True) another connection's exclusive queue.

Note that in AMQP, server errors are grouped into "connection errors" and "channel errors", and both are fatal. That is, if the server returns a channel error, it will then close the channel which caused the error; and if it returns a connection error, it will then close the connection. The AMQPClassic class's Error Codes page includes AMQP's various connection and channel errors.

DeleteExchange Method (IPWorksMQ_AMQPClassic Class)

Deletes an exchange.

Object Oriented Interface

public function doDeleteExchange($channelname, $exchangename, $ifunused, $nowait);

Procedural Interface

ipworksmq_amqpclassic_do_deleteexchange($res, $channelname, $exchangename, $ifunused, $nowait);

Remarks

This method is used to delete an exchange.

ChannelName controls what channel the class will send the request over. While any channel can technically be used, keep in mind that the server will close it if a channel error occurs. For this reason, it is good practice to make requests such as this one using a channel that is not involved in message publishing or consumption.

ExchangeName must be a non-empty string consisting only of letters, digits, hyphens, underscores, periods, and colons. It must be no longer than 255 characters, and must not begin with amq..

When IfUnused is True, the server will only delete the exchange if no queues are bound to it.

The NoWait parameter, if True, will cause the server to execute the request asynchronously. For asynchronous request handling, the server only sends back a response in case of an error.

An exception is thrown if no channel with the given ChannelName exists, or if the server returns an error because:

  • The value passed for ExchangeName fails one or more of the constraints described above.
  • No exchange named ExchangeName exists. (This does not apply for RabbitMQ; attempting to delete a non-existent exchange will always succeed.)
  • The IfUnused parameter was True, but the exchange still had one or more queues bound to it.

Note that in AMQP, server errors are grouped into "connection errors" and "channel errors", and both are fatal. That is, if the server returns a channel error, it will then close the channel which caused the error; and if it returns a connection error, it will then close the connection. The AMQPClassic class's Error Codes page includes AMQP's various connection and channel errors.

DeleteQueue Method (IPWorksMQ_AMQPClassic Class)

Deletes a queue.

Object Oriented Interface

public function doDeleteQueue($channelname, $queuename, $ifunused, $ifempty, $nowait);

Procedural Interface

ipworksmq_amqpclassic_do_deletequeue($res, $channelname, $queuename, $ifunused, $ifempty, $nowait);

Remarks

This method is used to delete the queue named QueueName.

After each successful call to this method, the class populates the QueueMessageCount property with the number of messages deleted along with the queue. (Note that this does not occur if the NoWait parameter is set to True.)

ChannelName controls what channel the class will send the request over. While any channel can technically be used, keep in mind that the server will close it if a channel error occurs. For this reason, it is good practice to make requests such as this one using a channel that is not involved in message publishing or consumption.

QueueName must be a non-empty string consisting only of letters, digits, hyphens, underscores, periods, and colons. It must be no longer than 255 characters, and must not begin with amq..

When IfUnused is True, the server will only delete the queue if no consumers are attached to it.

When IfEmpty is True, the server will only delete the queue if it has no messages in it. (When IfEmpty is False, servers will typically move any remaining messages to a dead-letter queue, if one is available.)

The NoWait parameter, if True, will cause the server to execute the request asynchronously. For asynchronous request handling, the server only sends back a response in case of an error.

An exception is thrown if no channel with the given ChannelName exists, or if the server returns an error because:

  • The value passed for QueueName fails one or more of the constraints described above.
  • No queue named QueueName exists. (This does not apply for RabbitMQ; attempting to delete a non-existent queue will always succeed.)
  • The IfUnused parameter was True, but the queue still had one or more consumers attached to it.
  • The IfEmpty parameter was True, but the queue still had one or more messages in it.

Note that in AMQP, server errors are grouped into "connection errors" and "channel errors", and both are fatal. That is, if the server returns a channel error, it will then close the channel which caused the error; and if it returns a connection error, it will then close the connection. The AMQPClassic class's Error Codes page includes AMQP's various connection and channel errors.

Disconnect Method (IPWorksMQ_AMQPClassic Class)

This method disconnects from the remote host.

Object Oriented Interface

public function doDisconnect();

Procedural Interface

ipworksmq_amqpclassic_do_disconnect($res);

Remarks

This method disconnects from the remote host. Calling this method is equivalent to setting the Connected property to False.

DoEvents Method (IPWorksMQ_AMQPClassic Class)

Processes events from the internal message queue.

Object Oriented Interface

public function doEvents();

Procedural Interface

ipworksmq_amqpclassic_do_doevents($res);

Remarks

When DoEvents is called, the class processes any available events. If no events are available, it waits for a preset period of time, and then returns.

EnablePublishConfirms Method (IPWorksMQ_AMQPClassic Class)

Enables publish confirmations mode for a channel.

Object Oriented Interface

public function doEnablePublishConfirms($channelname, $nowait);

Procedural Interface

ipworksmq_amqpclassic_do_enablepublishconfirms($res, $channelname, $nowait);

Remarks

This method enables publish confirmations mode for the channel with the given ChannelName.

While a channel is in publish confirmations mode, the server will acknowledge each message published by the class. The class will wait to fire the MessageOut event until it receives this acknowledgement. (Note that this mode is only available when the RabbitMQCompatible configuration setting is enabled.)

Note that a channel will stay in publish confirmations mode, once enabled, until it is deleted.

The NoWait parameter, if True, will cause the server to execute the request asynchronously. For asynchronous request handling, the server only sends back a response in case of an error.

An exception is thrown if the RabbitMQCompatible configuration setting is currently False, if no channel with the given ChannelName exists, or if EnableTransactionMode has been called for the specified channel previously.

EnableTransactionMode Method (IPWorksMQ_AMQPClassic Class)

Enables transaction mode for a channel.

Object Oriented Interface

public function doEnableTransactionMode($channelname);

Procedural Interface

ipworksmq_amqpclassic_do_enabletransactionmode($res, $channelname);

Remarks

This method enables transaction mode for the channel with the given ChannelName.

While a channel is in transaction mode, all messages published and acknowledgements sent over it will be part of a transaction, and the server will wait to process them until the transaction is either committed or rolled back.

To commit the current transaction on a channel, call CommitTransaction; and to roll it back (and discard the messages and acknowledgements that were part of it), call RollbackTransaction.

Keep in mind that, according to the AMQP 0.9.1 specification:

  • A new transaction is always started immediately after committing or rolling back the current one, which means that...
  • ...a channel will stay in transaction mode, once enabled, until it is deleted.
  • Transactions are only guaranteed to be atomic if all messages published and acknowledgements sent affect a single queue.
  • Any messages published on a channel in transaction mode that have the Mandatory or Immediate flags set are not guaranteed to be included in the transaction.

An exception is thrown if no channel with the given ChannelName exists, or if EnablePublishConfirms has been called for the specified channel previously.

FetchMessage Method (IPWorksMQ_AMQPClassic Class)

Attempts to fetch a message from a given queue.

Object Oriented Interface

public function doFetchMessage($channelname, $queuename, $noack);

Procedural Interface

ipworksmq_amqpclassic_do_fetchmessage($res, $channelname, $queuename, $noack);

Remarks

This method attempts to fetch a message from the queue named QueueName over the channel named ChannelName.

If a message is fetched as a result of this method being called, it is immediately added to the IncomingMessage* properties, the ReceivedMessage* properties are populated, and the MessageIn event fires.

Even if no message gets fetched, the MessageIn event will still fire as long as the request was successful. The server returns the number of available messages in the specified queue in response to all successful fetch requests, and that count is exposed by MessageIn event's MessageCount parameter. Refer to the MessageIn event for more information.

QueueName must be a non-empty string consisting only of letters, digits, hyphens, underscores, periods, and colons. It must be no longer than 255 characters.

The NoAck parameter controls whether the server will expect the class to acknowledge the fetched message. Refer to MessageIn for more information about acknowledging messages.

An exception is thrown if no channel with the given ChannelName exists, or if the server returns an error because:

  • No queue with the given QueueName exists.
  • The specified queue exists, but is locked or otherwise unavailable to consume from (e.g., an exclusive consumer might be attached to it).

Note that in AMQP, server errors are grouped into "connection errors" and "channel errors", and both are fatal. That is, if the server returns a channel error, it will then close the channel which caused the error; and if it returns a connection error, it will then close the connection. The AMQPClassic class's Error Codes page includes AMQP's various connection and channel errors.

Receiving a Message // MessageIn event handler. amqpc1.OnMessageIn += (s, e) => { if (e.MessageCount == -1) { // The server pushed a message to us asynchronously due to a consumer we created. Console.WriteLine("The server pushed this message to us via consumer '" + e.ConsumerTag + "':"); Console.WriteLine(amqpc1.ReceivedMessage.Body); } else if (e.DeliveryTag > 0) { // We pulled a message from a queue with the FetchMessage() method. Console.WriteLine("Message successfully pulled:"); Console.WriteLine(amqpc1.ReceivedMessage.Body); Console.WriteLine(e.MessageCount + " messages are still available to pull."); } else { // We tried to pull a message, but there were none available to pull. Console.WriteLine("No messages available to pull."); } }; // Attach a consumer to "MyQueue". amqpc1.Consume("channel", "MyQueue", "consumerTag", false, true, false, false); // Or, try to fetch a message from "MyQueue". amqpc1.FetchMessage("channel", "MyQueue", true);

Interrupt Method (IPWorksMQ_AMQPClassic Class)

Interrupt the current action and disconnects from the remote host.

Object Oriented Interface

public function doInterrupt();

Procedural Interface

ipworksmq_amqpclassic_do_interrupt($res);

Remarks

This method will interrupt the current method (if applicable) and cause the class to disconnect from the remote host.

PublishMessage Method (IPWorksMQ_AMQPClassic Class)

Publishes a message.

Object Oriented Interface

public function doPublishMessage($channelname, $exchangename, $routingkey, $mandatory, $immediate);

Procedural Interface

ipworksmq_amqpclassic_do_publishmessage($res, $channelname, $exchangename, $routingkey, $mandatory, $immediate);

Remarks

This method is used to publish the message specified by the Message* properties to the exchange named ExchangeName over the channel specified by ChannelName.

When this method is called, the message to publish is immediately added to the OutgoingMessage* properties, and the MessageOut event fires once it has been sent (or, if the specified channel is in "publish confirmations" mode, after the server has acknowledged it).

Note that all AMQP 0.9.1 servers automatically bind all queues to their default exchange (which is always a direct exchange with no name) using each queue's name as the binding's routing key. This makes it easy to send a message to a specific queue without having to declare bindings; just call PublishMessage, pass empty string for ExchangeName, and the name of the desired queue for RoutingKey.

Note that messages published over channels which are in either transaction or "publish confirmations" mode may be handled differently than they would be on a channel in normal mode. Refer to the EnableTransactionMode and EnablePublishConfirms methods for more information about what each mode entails.

The server's default exchange may be specified by passing empty string for ExchangeName. Otherwise, ExchangeName must be a non-empty string consisting only of letters, digits, hyphens, underscores, periods, and colons. It must be no longer than 255 characters.

The RoutingKey parameter specifies the message's routing key. Whether this parameter needs to be non-empty, and what format it should have if so, depends on the type of exchange it is being sent to. Some exchange types may use information included with the message, such as its MessageHeaders. Refer to BindQueue for more information about how routing keys are used, and to your server's documentation for information on what it expects.

The Mandatory parameter controls what the server should do if the message can't be routed to any queue (either because it isn't eligible for any of the queues bound to the specified exchange because of how their bindings are configured, or because no queues are bound to the exchange in the first place). If True, the server will return the message, at which point the MessageReturned event will be fired. If False, the server will drop the message.

The Immediate parameter controls what the server should do if the message can't be immediately delivered to any consumer (either because it cannot be routed to a queue, or because the queues it can be routed to have no active consumers attached to them). If True, the server will return the message, at which point the MessageReturned event will be fired. If False, the server will queue the message if possible, or drop it if not.

An exception is thrown if no channel with the given ChannelName exists, or if the server returns an error because:

  • The value passed for ExchangeName fails one or more of the constraints described above.
  • No exchange named ExchangeName exists.
  • The message is rejected for some reason.

Note that in AMQP, server errors are grouped into "connection errors" and "channel errors", and both are fatal. That is, if the server returns a channel error, it will then close the channel which caused the error; and if it returns a connection error, it will then close the connection. The AMQPClassic class's Error Codes page includes AMQP's various connection and channel errors.

Publishing a Message amqpc1.Message.Body = "Hello, world!"; // Publish a message to the server's default (no-name) exchange, using the name of a specific queue as the routing key. amqpc1.PublishMessage("channel", "", "MyQueue", false, false); // Publish a message to the "MyExchange" exchange, using the routing key "MyRoutingKey". amqpc1.PublishMessage("channel", "MyExchange", "MyRoutingKey", false, false);

PurgeQueue Method (IPWorksMQ_AMQPClassic Class)

Purges all messages from a queue.

Object Oriented Interface

public function doPurgeQueue($channelname, $queuename, $nowait);

Procedural Interface

ipworksmq_amqpclassic_do_purgequeue($res, $channelname, $queuename, $nowait);

Remarks

This method purges all messages from the queue named QueueName. Messages which have been sent but are awaiting acknowledgement are not affected.

After each successful call to this method, the class populates the QueueMessageCount property with the number of messages purged from the queue. (Note that this does not occur if the NoWait parameter is set to True.)

ChannelName controls what channel the class will send the request over. While any channel can technically be used, keep in mind that the server will close it if a channel error occurs. For this reason, it is good practice to make requests such as this one using a channel that is not involved in message publishing or consumption.

QueueName must be a non-empty string consisting only of letters, digits, hyphens, underscores, periods, and colons. It must be no longer than 255 characters.

The NoWait parameter, if True, will cause the server to execute the request asynchronously. For asynchronous request handling, the server only sends back a response in case of an error.

An exception is thrown if no channel with the given ChannelName exists, or if the server returns an error because no queue named QueueName exists.

Note that in AMQP, server errors are grouped into "connection errors" and "channel errors", and both are fatal. That is, if the server returns a channel error, it will then close the channel which caused the error; and if it returns a connection error, it will then close the connection. The AMQPClassic class's Error Codes page includes AMQP's various connection and channel errors.

Recover Method (IPWorksMQ_AMQPClassic Class)

Request that the server redeliver all messages on a given channel that have not been acknowledged.

Object Oriented Interface

public function doRecover($channelname, $requeue);

Procedural Interface

ipworksmq_amqpclassic_do_recover($res, $channelname, $requeue);

Remarks

This method is used to request that the server redeliver all messages that it previously sent to the class on the channel specified by ChannelName which are still awaiting acknowledgement.

A call to this method may cause the server to redeliver zero or more messages over the channel specified by ChannelName. Those messages will cause the MessageIn event to fire with its Redelivered event parameter set to True.

The Requeue parameter controls how the server should attempt to redeliver the messages awaiting acknowledgement. If set to True, the server will simple put the messages back on their original queues, and they will be delivered like any other queued messages (potentially to other consumers). If set to False, the server will redeliver the messages to the class directly.

An exception is thrown if no channel with the given ChannelName exists, or (for RabbitMQ only) if the server returns an error because Requeue was False. (RabbitMQ only supports setting Requeue to True.)

Note that in AMQP, server errors are grouped into "connection errors" and "channel errors", and both are fatal. That is, if the server returns a channel error, it will then close the channel which caused the error; and if it returns a connection error, it will then close the connection. The AMQPClassic class's Error Codes page includes AMQP's various connection and channel errors.

Reset Method (IPWorksMQ_AMQPClassic Class)

Reset the class.

Object Oriented Interface

public function doReset();

Procedural Interface

ipworksmq_amqpclassic_do_reset($res);

Remarks

This method will reset the class's properties to their default values.

ResetMessage Method (IPWorksMQ_AMQPClassic Class)

Resets the Message properties.

Object Oriented Interface

public function doResetMessage();

Procedural Interface

ipworksmq_amqpclassic_do_resetmessage($res);

Remarks

This method resets the Message* properties.

RollbackTransaction Method (IPWorksMQ_AMQPClassic Class)

Rolls back the current transaction for a channel.

Object Oriented Interface

public function doRollbackTransaction($channelname);

Procedural Interface

ipworksmq_amqpclassic_do_rollbacktransaction($res, $channelname);

Remarks

This method rolls back the current transaction for the channel with the given ChannelName. A new transaction is started immediately after the current one is rolled back.

Refer to EnableTransactionMode for more information about transactions.

An exception is thrown if a channel with the given ChannelName doesn't exist, or if the server returns an error because the channel does not have transaction mode enabled.

Note that in AMQP, server errors are grouped into "connection errors" and "channel errors", and both are fatal. That is, if the server returns a channel error, it will then close the channel which caused the error; and if it returns a connection error, it will then close the connection. The AMQPClassic class's Error Codes page includes AMQP's various connection and channel errors.

SetChannelAccept Method (IPWorksMQ_AMQPClassic Class)

Disables or enables message acceptance for a given channel.

Object Oriented Interface

public function doSetChannelAccept($channelname, $accept);

Procedural Interface

ipworksmq_amqpclassic_do_setchannelaccept($res, $channelname, $accept);

Remarks

This method is used to disable and enable message acceptance for the channel specified by ChannelName.

A channel is always configured to accept messages when first created, allowing the server to freely deliver messages to the class for any consumers that have been created on that channel using the Consume method.

Disabling message acceptance for a channel prevents the server from automatically delivering messages to the class over it; however, it is still possible to use the FetchMessage method to synchronously attempt to retrieve a message on a channel with message acceptance disabled.

An exception is thrown if no channel with the given ChannelName exists, or (for RabbitMQ only) if the server returns an error because Accept was False. (RabbitMQ does not support disabling message acceptance.)

Note that in AMQP, server errors are grouped into "connection errors" and "channel errors", and both are fatal. That is, if the server returns a channel error, it will then close the channel which caused the error; and if it returns a connection error, it will then close the connection. The AMQPClassic class's Error Codes page includes AMQP's various connection and channel errors.

SetQoS Method (IPWorksMQ_AMQPClassic Class)

Requests a specific quality of service (QoS).

Object Oriented Interface

public function doSetQoS($channelname, $prefetchsize, $prefetchcount, $global);

Procedural Interface

ipworksmq_amqpclassic_do_setqos($res, $channelname, $prefetchsize, $prefetchcount, $global);

Remarks

This method is used to request a specific quality of service for a certain scope. When the PrefetchSize and/or PrefetchCount are set for a certain scope, the server will limit how many messages it sends to the class before stopping to wait for or or more of them to be acknowledged.

ChannelName is the name of the channel which is used to send the request. Depending on the server and what Global is set to, it may also be significant to the request itself (refer to the Global parameter's description, below, for more information).

PrefetchSize specifies a window size in bytes; i.e., the server will stop sending messages if the total size of all of the currently unacknowledged messages already sent, plus the size of the next message that could be sent, exceeds PrefetchSize bytes. A PrefetchSize of 0 indicates no limit. (Note that RabbitMQ does not support prefetch size limits.)

PrefetchCount specifies the number of unacknowledged messages the server will limit itself to sending. A PrefetchCount of 0 indicates no limit.

Global specifies the scope which the QoS request should apply to. It is interpreted differently based on whether the server is RabbitMQ or not. Refer to this table:

Global is...RabbitMQ Other Servers
False QoS will be applied individually to each new consumer on the specified channel (existing consumers are unaffected).QoS applied to all existing and new consumers on the specified channel.
True QoS applied to all existing and new consumers on the specified channel. QoS applied to all existing and new consumers on the whole connection.

Keep the following things in mind when using QoS:

  • The limits specified by a QoS request only affect messages that require acknowledgement.
  • How the server chooses to handle interactions between QoS settings at different scopes is server-dependent.

An exception is thrown if no channel with the given ChannelName exists, or if the server returns an error for any reason.

Note that in AMQP, server errors are grouped into "connection errors" and "channel errors", and both are fatal. That is, if the server returns a channel error, it will then close the channel which caused the error; and if it returns a connection error, it will then close the connection. The AMQPClassic class's Error Codes page includes AMQP's various connection and channel errors.

UnbindQueue Method (IPWorksMQ_AMQPClassic Class)

Removes a previously-created queue binding.

Object Oriented Interface

public function doUnbindQueue($channelname, $queuename, $exchangename, $routingkey);

Procedural Interface

ipworksmq_amqpclassic_do_unbindqueue($res, $channelname, $queuename, $exchangename, $routingkey);

Remarks

This method removes a previously-created queue binding.

ChannelName controls what channel the class will send the request over. While any channel can technically be used, keep in mind that the server will close it if a channel error occurs. For this reason, it is good practice to make requests such as this one using a channel that is not involved in message publishing or consumption.

QueueName must be a non-empty string consisting only of letters, digits, hyphens, underscores, periods, and colons. It must be no longer than 255 characters.

The server's default exchange may be specified by passing empty string for ExchangeName. Otherwise, ExchangeName must be a non-empty string consisting only of letters, digits, hyphens, underscores, periods, and colons. It must be no longer than 255 characters.

RoutingKey should be the same routing key used when originally creating the binding that is to be removed. For bindings created using arguments instead of a routing key, the Argument* properties must contain the same items used originally instead.

An exception is thrown if no channel with the given ChannelName exists, or if the server returns an error because:

  • No queue with the given QueueName exists. (Does not apply to RabbitMQ.)
  • No exchange with the given ExchangeName exists. (Does not apply to RabbitMQ.)

Note that in AMQP, server errors are grouped into "connection errors" and "channel errors", and both are fatal. That is, if the server returns a channel error, it will then close the channel which caused the error; and if it returns a connection error, it will then close the connection. The AMQPClassic class's Error Codes page includes AMQP's various connection and channel errors.

ChannelReadyToSend Event (IPWorksMQ_AMQPClassic Class)

Fires when a channel is ready to send messages.

Please refer to the Error Codes section for more information.

Error Event (IPWorksMQ_AMQPClassic Class)

Information about errors during data delivery.

Object Oriented Interface

public function fireError($param);

Procedural Interface

ipworksmq_amqpclassic_register_callback($res, 5, array($this, 'fireError'));

Parameter List

 'errorcode'
'description'

Remarks

Log Event (IPWorksMQ_AMQPClassic Class)

Fires once for each log message.

Object Oriented Interface

public function fireLog($param);

Procedural Interface

ipworksmq_amqpclassic_register_callback($res, 6, array($this, 'fireLog'));

Parameter List

 'loglevel'
'message'
'logtype'

Remarks

This event fires once for each log message generated by the class. The verbosity is controlled by the LogLevel setting.

LogLevel indicates the level of the Message. Possible values are:

0 (None) No events are logged.
1 (Info - default) Informational events are logged.
2 (Verbose) Detailed data is logged.
3 (Debug) Debug data is logged.

LogType identifies the type of log entry. Possible values are:

  • Info: General information about the class.
  • Frame: Frame status messages.

MessageIn Event (IPWorksMQ_AMQPClassic Class)

Fires when a message is received; as well as when an attempt is made to fetch a message from a currently empty queue.

Object Oriented Interface

public function fireMessageIn($param);

Procedural Interface

ipworksmq_amqpclassic_register_callback($res, 7, array($this, 'fireMessageIn'));

Parameter List

 'channelname'
'consumertag'
'deliverytag'
'redelivered'
'exchangename'
'routingkey'
'messagecount'
'accept'

Remarks

This event fires anytime a message is received. There are two possible ways for the class to receive a message:

  • Messages can be asynchronously pushed to the class from the server. At any point in time, the server may push a message to the class from a queue that the Consume method has been used to attach a consumer to.
  • Messages can be synchronously pulled from the server by the class. The FetchMessage method is used to attempt to pull (or "fetch") messages from a specific queue.

This event also fires anytime FetchMessage is called against a queue that currently has no messages available to pull. This is a special case, and results in only the ChannelName and MessageCount event parameters being populated.

Other than that special case, and any exceptions noted below, this event's parameters are populated the same way regardless of the manner in which messages are received.

ChannelName always reflects the name of the associated channel.

ConsumerTag reflects the consumer tag associated with the consumer that caused the server to push the message to the class. (ConsumerTag is always empty for messages pulled from the server by FetchMessage since no consumers are involved.)

DeliveryTag reflects the server-assigned, channel-specific delivery tag number for the incoming message.

Redelivered reflects whether the server is redelivering a message that is has delivered previously.

ExchangeName reflects the name of the exchange to which the incoming message was originally published. (If the message was originally published to the server's default exchange, whose name is always the empty string, ExchangeName will also be empty.)

RoutingKey reflects the routing key that the message was originally published with.

MessageCount is always -1 when this event fires due to a message being pushed to the class by the server. When this event fires as a result of FetchMessage being called, MessageCount reflects the number of messages still available in the queue the class tried to pull a message from (even if there were no messages available to pull).

The Accept parameter can be set to control how the class responds to the incoming message, if it needs to be acknowledged (if the message doesn't need to be acknowledged, the value set to the Accept parameter is ignored). Valid values are:

  • 0 - default: Accept the message; send a positive acknowledgement.
  • 1: Silently accept the message; don't send any acknowledgement.
  • 2: Accept the message; send a cumulative positive acknowledgement coving this, and all previously unacknowledged, messages.
  • 3: Reject the message; send a negative acknowledgement for it, and instruct the server not to return it to the queue.
  • 4: Reject the message; send a negative acknowledgement for it, and instruct the server to return it to the queue.
If the RabbitMQCompatible configuration setting is enabled, then the NackMultiple configuration setting can be used to control whether the two "reject" options (3 and 4) should function as cumulative or singular negative acknowledgements. By default NackMultiple is disabled, and all negative acknowledgements are singular.

If the value provided for the Accept parameter isn't one of those described above, the default (0) will be used instead.

Receiving a Message // MessageIn event handler. amqpc1.OnMessageIn += (s, e) => { if (e.MessageCount == -1) { // The server pushed a message to us asynchronously due to a consumer we created. Console.WriteLine("The server pushed this message to us via consumer '" + e.ConsumerTag + "':"); Console.WriteLine(amqpc1.ReceivedMessage.Body); } else if (e.DeliveryTag > 0) { // We pulled a message from a queue with the FetchMessage() method. Console.WriteLine("Message successfully pulled:"); Console.WriteLine(amqpc1.ReceivedMessage.Body); Console.WriteLine(e.MessageCount + " messages are still available to pull."); } else { // We tried to pull a message, but there were none available to pull. Console.WriteLine("No messages available to pull."); } }; // Attach a consumer to "MyQueue". amqpc1.Consume("channel", "MyQueue", "consumerTag", false, true, false, false); // Or, try to fetch a message from "MyQueue". amqpc1.FetchMessage("channel", "MyQueue", true);

MessageOut Event (IPWorksMQ_AMQPClassic Class)

Fires when a message is published.

Object Oriented Interface

public function fireMessageOut($param);

Procedural Interface

ipworksmq_amqpclassic_register_callback($res, 8, array($this, 'fireMessageOut'));

Parameter List

 'channelname'
'exchangename'
'routingkey'
'messageid'
'deliverytag'
'accepted'

Remarks

This event fires anytime a message is published; or after an outgoing message has been acknowledged by the server, if the channel it was published on is in "publish confirmations" mode.

ChannelName reflects the name of the channel the message was published on.

ExchangeName reflects the name of the exchange the message was published to. (If the message was published to the server's default exchange, whose name is always the empty string, ExchangeName will also be empty.)

RoutingKey reflects the routing key that the message was published with.

MessageId reflects the message's unique Id, if one was set.

DeliveryTag reflects the channel-specific delivery tag number for the message. (Note that this is only populated for messages published on a channel in "publish confirmations" mode; otherwise it will be set to -1.)

Accepted indicates whether the server published back a positive True or negative False acknowledgement for the outgoing message. Note that this is only valid for messages published on a channel in "publish confirmations" mode; Accepted will always be True messages published on a channel in normal or transaction mode.

Refer to EnablePublishConfirms for more information about channels in "publish confirmations" mode.

MessageReturned Event (IPWorksMQ_AMQPClassic Class)

Fires if a previously published message is returned by the server due to it being undeliverable.

Object Oriented Interface

public function fireMessageReturned($param);

Procedural Interface

ipworksmq_amqpclassic_register_callback($res, 9, array($this, 'fireMessageReturned'));

Parameter List

 'channelname'
'replycode'
'replytext'
'exchangename'
'routingkey'

Remarks

This event fires if the server returns a previously published message because it could not deliver it. Typically, messages are only undeliverable in one of the following situations:

  • The message was originally published with the Mandatory option enabled, but there were no queues it could be routed to.
  • The message was originally published with the Immediate option enabled, but there were no consumers it could be delivered to immediately on any queue it was routed to (or there were no queues it could be routed to).

The ReceivedMessage* properties will be populated with the returned message.

ChannelName reflects the name of the channel the message was originally published on.

ReplyCode will be an AMQP error code that indicates the reason why the message was returned. (Tip: The AMQPClassic class's Error Codes page includes the various AMQP error codes.)

ReplyText will be a message with further details about why the message was returned.

ExchangeName reflects the name of the exchange to which the message was originally published. (If the message was originally published to the server's default exchange, whose name is always the empty string, ExchangeName will also be empty.)

RoutingKey reflects the routing key that the message was originally published with.

SSLServerAuthentication Event (IPWorksMQ_AMQPClassic Class)

Fired after the server presents its certificate to the client.

Object Oriented Interface

public function fireSSLServerAuthentication($param);

Procedural Interface

ipworksmq_amqpclassic_register_callback($res, 10, array($this, 'fireSSLServerAuthentication'));

Parameter List

 'certencoded'
'certsubject'
'certissuer'
'status'
'accept'

Remarks

This event is where the client can decide whether to continue with the connection process or not. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether to continue or not.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string "OK"). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.

SSLStatus Event (IPWorksMQ_AMQPClassic Class)

Shows the progress of the secure connection.

Object Oriented Interface

public function fireSSLStatus($param);

Procedural Interface

ipworksmq_amqpclassic_register_callback($res, 11, array($this, 'fireSSLStatus'));

Parameter List

 'message'

Remarks

The event is fired for informational and logging purposes only. Used to track the progress of the connection.

Config Settings (AMQPClassic Class)

The class accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

AMQPClassic Config Settings

AuthorizationIdentity:   The value to use as the authorization identity when SASL authentication is used.

When AuthScheme is set to smSASLPlain you may use this setting to specify an authorization identity to be used when authenticating.

ConsumerTag:   The consumer tag associated with the most recently created consumer.

Each time the Consume method is called to create a new consumer, the server will send back a confirmation which includes the consumer tag value for that consumer, and the class will update this setting's value accordingly.

It is possible to pass empty string for the ConsumerTag parameter when calling the Consume method, in which case the server will auto-generate a consumer tag.

Locale:   The desired message locale to use.

This setting specifies the desired message locale, which will be compared to the server's list of supported message locales during the connection process. A connection attempt will fail if this setting is set to a locale not supported by the server. This setting cannot be changed while connected.

The default value is "en_US", which is supported by all AMQP 0.9.1 servers.

Locales:   The message locales supported by the server.

After a connection attempt (regardless of its success) this setting will reflect the various message locales that the server supports.

The value of this setting is formatted as a space-separated list of message locales.

LogLevel:   The level of detail that is logged.

This setting controls the level of detail that is logged through the Log event. Possible values are:

0 (None) No events are logged.
1 (Info - default) Informational events are logged.
2 (Verbose) Detailed data is logged.
3 (Debug) Debug data is logged.

MaxChannelCount:   The maximum number of channels.

This setting specifies the maximum number of channels which can be opened. This setting cannot be changed while connected.

The default is 65535 (0xFFFF). Note that this value is negotiated during the connection process; if the value provided by the server is lower than the specified value, the server's value will be used instead (and this setting will be updated accordingly).

MaxFrameSize:   The maximum frame size.

This setting specifies the maximum frame size (in bytes) that the class will accept. This setting cannot be changed while connected.

The default is 2147483647 (0x7FFFFFFF). Note that this value is negotiated during the connection process; if the value provided by the server is lower than the specified value, the server's value will be used instead (and this setting will be updated accordingly).

Mechanisms:   The authentication mechanisms supported by the server.

After a connection attempt (regardless of its success) this setting will reflect the various authentication mechanisms that the server supports.

The value of this setting is formatted as a space-separated list of authentication mechanisms.

NackMultiple:   Whether negative acknowledgments should be cumulative or not.

If the RabbitMQCompatible configuration setting is enabled, this setting controls whether the negative message acknowledgments the class sends based on the value of the MessageIn event's Accept parameter should be cumulative (True) or singular (False - default).

This setting does nothing if the RabbitMQCompatible configuration setting is disabled.

ProtocolVersion:   The AMQP protocol version to conform to.

This setting can be queried to determine what AMQP protocol version the class conforms to.

Note: Currently this setting will always return "0.9.1", and cannot be changed. The AMQP class may be used instead of this one if AMQP 1.0 support is needed.

QueueConsumerCount:   The consumer count associated with the most recently created (or verified) queue.

Each time the DeclareQueue method is called successfully (and with its NoWait parameter set to False), the server returns information about the queue in question, causing the class to update this setting with the number of consumers attached to that queue.

QueueName:   The queue name associated with the most recently created (or verified) queue.

Each time the DeclareQueue method is called successfully (and with its NoWait parameter set to False), the server returns information about the queue in question, causing the class to update this setting with the name of that queue.

It is possible to pass empty string for the QueueName parameter when calling the DeclareQueue method to have the server create a new queue with an automatically generated name, which can then be retrieved by querying this setting.

RabbitMQCompatible:   Whether to operate in a mode compatible with RabbitMQ.

This setting controls whether the class will operate in such a way as to be compatible with RabbitMQ. When enabled, the class complies with the parts of the RabbitMQ AMQP 0.9.1 Errata that are relevant to AMQP 0.9.1 client implementations, as well as offering additional features to support RabbitMQ-specific extensions to the AMQP 0.9.1 specification.

The default is True.

TCPClient Config Settings

ConnectionTimeout:   Sets a separate timeout value for establishing a connection.

When set, this configuration setting allows you to specify a different timeout value for establishing a connection. Otherwise, the class will use Timeout for establishing a connection and transmitting/receiving data.

FirewallAutoDetect:   Tells the class whether or not to automatically detect and use firewall system settings, if available.

This configuration setting is provided for use by classs that do not directly expose Firewall properties.

FirewallHost:   Name or IP address of firewall (optional).

If a FirewallHost is given, requested connections will be authenticated through the specified firewall when connecting.

If the FirewallHost setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the FirewallHost setting is set to the corresponding address. If the search is not successful, an error is returned.

Note: This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallPassword:   Password to be used if authentication is to be used when connecting through the firewall.

If FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the given firewall. If the authentication fails, the class fails with an error.

Note: This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallPort:   The TCP port for the FirewallHost;.

The FirewallPort is set automatically when FirewallType is set to a valid value.

Note: This configuration setting is provided for use by classs that do not directly expose Firewall properties.

FirewallType:   Determines the type of firewall to connect through.

The appropriate values are as follows:

0No firewall (default setting).
1Connect through a tunneling proxy. FirewallPort is set to 80.
2Connect through a SOCKS4 Proxy. FirewallPort is set to 1080.
3Connect through a SOCKS5 Proxy. FirewallPort is set to 1080.
10Connect through a SOCKS4A Proxy. FirewallPort is set to 1080.

Note: This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallUser:   A user name if authentication is to be used connecting through a firewall.

If the FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the Firewall. If the authentication fails, the class fails with an error.

Note: This setting is provided for use by classs that do not directly expose Firewall properties.

KeepAliveInterval:   The retry interval, in milliseconds, to be used when a TCP keep-alive packet is sent and no response is received.

When set, TCPKeepAlive will automatically be set to True. A TCP keep-alive packet will be sent after a period of inactivity as defined by KeepAliveTime. If no acknowledgment is received from the remote host, the keep-alive packet will be sent again. This configuration setting specifies the interval at which the successive keep-alive packets are sent in milliseconds. This system default if this value is not specified here is 1 second.

Note: This value is not applicable in macOS.

KeepAliveTime:   The inactivity time in milliseconds before a TCP keep-alive packet is sent.

When set, TCPKeepAlive will automatically be set to True. By default, the operating system will determine the time a connection is idle before a Transmission Control Protocol (TCP) keep-alive packet is sent. This system default if this value is not specified here is 2 hours. In many cases, a shorter interval is more useful. Set this value to the desired interval in milliseconds.

Linger:   When set to True, connections are terminated gracefully.

This property controls how a connection is closed. The default is True.

In the case that Linger is True (default), two scenarios determine how long the connection will linger. In the first, if LingerTime is 0 (default), the system will attempt to send pending data for a connection until the default IP timeout expires.

In the second scenario, if LingerTime is a positive value, the system will attempt to send pending data until the specified LingerTime is reached. If this attempt fails, then the system will reset the connection.

The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the class returns control immediately, the system could hold system resources until all pending data are sent (even after your application closes).

Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (e.g., by a client acknowledgment), setting this property to False might be the appropriate course of action.

LingerTime:   Time in seconds to have the connection linger.

LingerTime is the time, in seconds, the socket connection will linger. This value is 0 by default, which means it will use the default IP timeout.

LocalHost:   The name of the local host through which connections are initiated or accepted.

The LocalHost setting contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface.

If the class is connected, the LocalHost setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multi-homed hosts (machines with more than one IP interface).

LocalPort:   The port in the local host where the class binds.

This must be set before a connection is attempted. It instructs the class to bind to a specific port (or communication endpoint) in the local machine.

Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established.

LocalPort cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.

This; setting is useful when trying to connect to services that require a trusted port in the client side. An example is the remote shell (rsh) service in UNIX systems.

MaxLineLength:   The maximum amount of data to accumulate when no EOL is found.

MaxLineLength is the size of an internal buffer, which holds received data while waiting for an EOL string.

If an EOL string is found in the input stream before MaxLineLength bytes are received, the DataIn event is fired with the EOL parameter set to True, and the buffer is reset.

If no EOL is found, and MaxLineLength bytes are accumulated in the buffer, the DataIn event is fired with the EOL parameter set to False, and the buffer is reset.

The minimum value for MaxLineLength is 256 bytes. The default value is 2048 bytes.

MaxTransferRate:   The transfer rate limit in bytes per second.

This configuration setting can be used to throttle outbound TCP traffic. Set this to the number of bytes to be sent per second. By default, this is not set and there is no limit.

ProxyExceptionsList:   A semicolon separated list of hosts and IPs to bypass when using a proxy.

This configuration setting optionally specifies a semicolon-separated list of hostnames or IP addresses to bypass when a proxy is in use. When requests are made to hosts specified in this property, the proxy will not be used. For instance:

www.google.com;www.nsoftware.com

TCPKeepAlive:   Determines whether or not the keep alive socket option is enabled.

If set to True, the socket's keep-alive option is enabled and keep-alive packets will be sent periodically to maintain the connection. Set KeepAliveTime and KeepAliveInterval to configure the timing of the keep-alive packets.

Note: This value is not applicable in Java.

TcpNoDelay:   Whether or not to delay when sending packets.

When true, the socket will send all data that is ready to send at once. When false, the socket will send smaller buffered packets of data at small intervals. This is known as the Nagle algorithm.

By default, this config is set to false.

UseIPv6:   Whether to use IPv6.

When set to 0 (default), the class will use IPv4 exclusively. When set to 1, the class will use IPv6 exclusively. To instruct the class to prefer IPv6 addresses, but use IPv4 if IPv6 is not supported on the system, this setting should be set to 2. The default value is 0. Possible values are:

0 IPv4 Only
1 IPv6 Only
2 IPv6 with IPv4 fallback

SSL Config Settings

LogSSLPackets:   Controls whether SSL packets are logged when using the internal security API.

When SSLProvider is set to Internal, this setting controls whether SSL packets should be logged. By default, this setting is False, as it is only useful for debugging purposes.

When enabled, SSL packet logs are output using the SSLStatus event, which will fire each time an SSL packet is sent or received.

Enabling this setting has no effect if SSLProvider is set to Platform.

OpenSSLCADir:   The path to a directory containing CA certificates.

This functionality is available only when the provider is OpenSSL.

The path set by this property should point to a directory containing CA certificates in PEM format. The files each contain one CA certificate. The files are looked up by the CA subject name hash value, which must hence be available. If more than one CA certificate with the same name hash value exist, the extension must be different (e.g. 9d66eef0.0, 9d66eef0.1 etc). OpenSSL recommends to use the c_rehash utility to create the necessary links. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.

OpenSSLCAFile:   Name of the file containing the list of CA's trusted by your application.

This functionality is available only when the provider is OpenSSL.

The file set by this property should contain a list of CA certificates in PEM format. The file can contain several CA certificates identified by

-----BEGIN CERTIFICATE-----

... (CA certificate in base64 encoding) ...

-----END CERTIFICATE-----

sequences. Before, between, and after the certificates text is allowed which can be used e.g. for descriptions of the certificates. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.

OpenSSLCipherList:   A string that controls the ciphers to be used by SSL.

This functionality is available only when the provider is OpenSSL.

The format of this string is described in the OpenSSL man page ciphers(1) section "CIPHER LIST FORMAT". Please refer to it for details. The default string "DEFAULT" is determined at compile time and is normally equivalent to "ALL:!ADH:RC4+RSA:+SSLv2:@STRENGTH".

OpenSSLPrngSeedData:   The data to seed the pseudo random number generator (PRNG).

This functionality is available only when the provider is OpenSSL.

By default OpenSSL uses the device file "/dev/urandom" to seed the PRNG and setting OpenSSLPrngSeedData is not required. If set, the string specified is used to seed the PRNG.

ReuseSSLSession:   Determines if the SSL session is reused.

If set to true, the class will reuse the context if and only if the following criteria are met:

  • The target host name is the same.
  • The system cache entry has not expired (default timeout is 10 hours).
  • The application process that calls the function is the same.
  • The logon session is the same.
  • The instance of the class is the same.

SSLCACertFilePaths:   The paths to CA certificate files on Unix/Linux.

This setting specifies the paths on disk to CA certificate files on Unix/Linux.

The value is formatted as a list of paths separated by semicolons. The class will check for the existence of each file in the order specified. When a file is found the CA certificates within the file will be loaded and used to determine the validity of server or client certificates.

The default value is:

/etc/ssl/ca-bundle.pem;/etc/pki/tls/certs/ca-bundle.crt;/etc/ssl/certs/ca-certificates.crt;/etc/pki/tls/cacert.pem

SSLCACerts:   A newline separated list of CA certificate to use during SSL client authentication.

This setting specifies one or more CA certificates to be included in the request when performing SSL client authentication. Some servers require the entire chain, including CA certificates, to be presented when performing SSL client authentication. The value of this setting is a newline (CrLf) separated list of certificates. For instance:

-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw
...
eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w
F0I1XhM+pKj7FjDr+XNj
-----END CERTIFICATE-----
\r \n
-----BEGIN CERTIFICATE-----
MIIEFjCCAv6gAwIBAgIQetu1SMxpnENAnnOz1P+PtTANBgkqhkiG9w0BAQUFADBp
..
d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA
-----END CERTIFICATE-----

SSLCheckCRL:   Whether to check the Certificate Revocation List for the server certificate.

This setting specifies whether the class will check the Certificate Revocation List specified by the server certificate. If set to 1 or 2, the class will first obtain the list of CRL URLs from the server certificate's CRL distribution points extension. The class will then make HTTP requests to each CRL endpoint to check the validity of the server's certificate. If the certificate has been revoked or any other issues are found during validation the class fails with an error.

When set to 0 (default) the CRL check will not be performed by the class. When set to 1, it will attempt to perform the CRL check, but will continue without an error if the server's certificate does not support CRL. When set to 2, it will perform the CRL check and will throw an error if CRL is not supported.

This configuration setting is only supported in the Java, C#, and C++ editions. In the C++ edition, it is only supported on Windows operating systems.

SSLCheckOCSP:   Whether to use OCSP to check the status of the server certificate.

This setting specifies whether the class will use OCSP to check the validity of the server certificate. If set to 1 or 2, the class will first obtain the OCSP URL from the server certificate's OCSP extension. The class will then locate the issuing certificate and make an HTTP request to the OCSP endpoint to check the validity of the server's certificate. If the certificate has been revoked or any other issues are found during validation the class fails with an error.

When set to 0 (default) the class will not perform an OCSP check. When set to 1, it will attempt to perform the OCSP check, but will continue without an error if the server's certificate does not support OCSP. When set to 2, it will perform the OCSP check and will throw an error if OCSP is not supported.

This configuration setting is only supported in the Java, C#, and C++ editions. In the C++ edition, it is only supported on Windows operating systems.

SSLCipherStrength:   The minimum cipher strength used for bulk encryption.

This minimum cipher strength largely dependent on the security modules installed on the system. If the cipher strength specified is not supported, an error will be returned when connections are initiated.

Please note that this setting contains the minimum cipher strength requested from the security library. The actual cipher strength used for the connection is shown by the SSLStatus event.

Use this setting with caution. Requesting a lower cipher strength than necessary could potentially cause serious security vulnerabilities in your application.

When the provider is OpenSSL, SSLCipherStrength is currently not supported. This functionality is instead made available through the OpenSSLCipherList config setting.

SSLEnabledCipherSuites:   The cipher suite to be used in an SSL negotiation.

The enabled cipher suites to be used in SSL negotiation.

By default, the enabled cipher suites will include all available ciphers ("*").

The special value "*" means that the class will pick all of the supported cipher suites. If SSLEnabledCipherSuites is set to any other value, only the specified cipher suites will be considered.

Multiple cipher suites are separated by semicolons.

Example values when SSLProvider is set to Platform: obj.config("SSLEnabledCipherSuites=*"); obj.config("SSLEnabledCipherSuites=CALG_AES_256"); obj.config("SSLEnabledCipherSuites=CALG_AES_256;CALG_3DES"); Possible values when SSLProvider is set to Platform include:

When TLS 1.3 is negotiated (see SSLEnabledProtocols) only the following cipher suites are supported:

  • TLS_AES_256_GCM_SHA384
  • TLS_CHACHA20_POLY1305_SHA256
  • TLS_AES_128_GCM_SHA256

SSLEnabledCipherSuites is used together with SSLCipherStrength.

SSLEnabledProtocols:   Used to enable/disable the supported security protocols.

Used to enable/disable the supported security protocols.

Not all supported protocols are enabled by default (the value of this setting is 4032). If you want more granular control over the enabled protocols, you can set this property to the binary 'OR' of one or more of the following values:

TLS1.312288 (Hex 3000)
TLS1.23072 (Hex C00) (Default)
TLS1.1768 (Hex 300) (Default)
TLS1 192 (Hex C0) (Default)
SSL3 48 (Hex 30)
SSL2 12 (Hex 0C)

SSLEnabledProtocols - TLS 1.3 Notes

By default when TLS 1.3 is enabled the class will use the internal TLS implementation when the SSLProvider is set to Automatic for all editions.

In editions which are designed to run on Windows SSLProvider can be set to Platform to use the platform implementation instead of the internal implementation. When configured in this manner, please note that the platform provider is only supported on Windows 11 / Windows Server 2022 and up. The default internal provider is available on all platforms and is not restricted to any specific OS version.

If set to 1 (Platform provider) please be aware of the following notes:

  • The platform provider is only available on Windows 11 / Windows Server 2022 and up.
  • SSLEnabledCipherSuites and other similar SSL configuration settings are not supported.
  • If SSLEnabledProtocols includes both TLS 1.3 and TLS 1.2 the above restrictions are still applicable even if TLS 1.2 is negotiated. Enabling TLS 1.3 with the platform provider changes the implementation used for all TLS versions.

SSLEnableRenegotiation:   Whether the renegotiation_info SSL extension is supported.

This setting specifies whether the renegotiation_info SSL extension will be used in the request when using the internal security API. This setting is true by default, but can be set to false to disable the extension.

This setting is only applicable when SSLProvider is set to Internal.

SSLIncludeCertChain:   Whether the entire certificate chain is included in the SSLServerAuthentication event.

This setting specifies whether the Encoded parameter of the SSLServerAuthentication event contains the full certificate chain. By default this value is False and only the leaf certificate will be present in the Encoded parameter of the SSLServerAuthentication event.

If set to True all certificates returned by the server will be present in the Encoded parameter of the SSLServerAuthentication event. This includes the leaf certificate, any intermediate certificate, and the root certificate.

SSLKeyLogFile:   The location of a file where per-session secrets are written for debugging purposes.

This setting optionally specifies the full path to a file on disk where per-session secrets are stored for debugging purposes.

When set, the class will save the session secrets in the same format as the SSLKEYLOGFILE environment variable functionality used by most major browsers and tools such as Chrome, Firefox, and cURL. This file can then be used in tools such as Wireshark to decrypt TLS traffice for debugging purposes. When writing to this file the class will only append, it will not overwrite previous values.

Note: This setting is only applicable when SSLProvider is set to Internal.

SSLNegotiatedCipher:   Returns the negotiated cipher suite.

Returns the cipher suite negotiated during the SSL handshake.

Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedCipher[connId]");

SSLNegotiatedCipherStrength:   Returns the negotiated cipher suite strength.

Returns the strength of the cipher suite negotiated during the SSL handshake.

Note: For server components (e.g.TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedCipherStrength[connId]");

SSLNegotiatedCipherSuite:   Returns the negotiated cipher suite.

Returns the cipher suite negotiated during the SSL handshake represented as a single string.

Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedCipherSuite[connId]");

SSLNegotiatedKeyExchange:   Returns the negotiated key exchange algorithm.

Returns the key exchange algorithm negotiated during the SSL handshake.

Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedKeyExchange[connId]");

SSLNegotiatedKeyExchangeStrength:   Returns the negotiated key exchange algorithm strength.

Returns the strenghth of the key exchange algorithm negotiated during the SSL handshake.

Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedKeyExchangeStrength[connId]");

SSLNegotiatedVersion:   Returns the negotiated protocol version.

Returns the protocol version negotiated during the SSL handshake.

Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedVersion[connId]");

SSLSecurityFlags:   Flags that control certificate verification.

The following flags are defined (specified in hexadecimal notation). They can be or-ed together to exclude multiple conditions:

0x00000001Ignore time validity status of certificate.
0x00000002Ignore time validity status of CTL.
0x00000004Ignore non-nested certificate times.
0x00000010Allow unknown Certificate Authority.
0x00000020Ignore wrong certificate usage.
0x00000100Ignore unknown certificate revocation status.
0x00000200Ignore unknown CTL signer revocation status.
0x00000400Ignore unknown Certificate Authority revocation status.
0x00000800Ignore unknown Root revocation status.
0x00008000Allow test Root certificate.
0x00004000Trust test Root certificate.
0x80000000Ignore non-matching CN (certificate CN not-matching server name).

This functionality is currently not available when the provider is OpenSSL.

SSLServerCACerts:   A newline separated list of CA certificate to use during SSL server certificate validation.

This setting optionally specifies one or more CA certificates to be used when verifying the server certificate. When verifying the server's certificate the certificates trusted by the system will be used as part of the verification process. If the server's CA certificates are not installed to the trusted system store, they may be specified here so they are included when performing the verification process. This setting should only be set if the server's CA certificates are not already trusted on the system and cannot be installed to the trusted system store.

The value of this setting is a newline (CrLf) separated list of certificates. For instance:

-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw
...
eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w

-----END CERTIFICATE-----

TLS12SignatureAlgorithms:   Defines the allowed TLS 1.2 signature algorithms when SSLProvider is set to Internal.

This setting specifies the allowed server certificate signature algorithms when SSLProvider is set to Internal and SSLEnabledProtocols is set to allow TLS 1.2.

When specified the class will verify that the server certificate signature algorithm is among the values specified in this setting. If the server certificate signature algorithm is unsupported the class fails with an error.

The format of this value is a comma separated list of hash-signature combinations. For instance: component.SSLProvider = TCPClientSSLProviders.sslpInternal; component.Config("SSLEnabledProtocols=3072"); //TLS 1.2 component.Config("TLS12SignatureAlgorithms=sha256-rsa,sha256-dsa,sha1-rsa,sha1-dsa"); The default value for this setting is sha512-ecdsa,sha512-rsa,sha512-dsa,sha384-ecdsa,sha384-rsa,sha384-dsa,sha256-ecdsa,sha256-rsa,sha256-dsa,sha224-ecdsa,sha224-rsa,sha224-dsa,sha1-ecdsa,sha1-rsa,sha1-dsa.

In order to not restrict the server's certificate signature algorithm, specify an empty string as the value for this setting, which will cause the signature_algorithms TLS 1.2 extension to not be sent.

TLS12SupportedGroups:   The supported groups for ECC.

This setting specifies a comma separated list of named groups used in TLS 1.2 for ECC.

The default value is ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1.

When using TLS 1.2 and SSLProvider is set to Internal, the values refer to the supported groups for ECC. The following values are supported:

  • "ecdhe_secp256r1" (default)
  • "ecdhe_secp384r1" (default)
  • "ecdhe_secp521r1" (default)

TLS13KeyShareGroups:   The groups for which to pregenerate key shares.

This setting specifies a comma separated list of named groups used in TLS 1.3 for key exchange. The groups specified here will have key share data pregenerated locally before establishing a connection. This can prevent an additional round trip during the handshake if the group is supported by the server.

The default value is set to balance common supported groups and the computational resources required to generate key shares. As a result only some groups are included by default in this setting.

Note: All supported groups can always be used during the handshake even if not listed here, but if a group is used which is not present in this list it will incur an additional round trip and time to generate the key share for that group.

In most cases this setting does not need to be modified. This should only be modified if there is a specific reason to do so.

The default value is ecdhe_x25519,ecdhe_secp256r1,ecdhe_secp384r1,ffdhe_2048,ffdhe_3072

The values are ordered from most preferred to least preferred. The following values are supported:

  • "ecdhe_x25519" (default)
  • "ecdhe_x448"
  • "ecdhe_secp256r1" (default)
  • "ecdhe_secp384r1" (default)
  • "ecdhe_secp521r1"
  • "ffdhe_2048" (default)
  • "ffdhe_3072" (default)
  • "ffdhe_4096"
  • "ffdhe_6144"
  • "ffdhe_8192"

TLS13SignatureAlgorithms:   The allowed certificate signature algorithms.

This setting holds a comma separated list of allowed signature algorithms. Possible values are:

  • "ed25519" (default)
  • "ed448" (default)
  • "ecdsa_secp256r1_sha256" (default)
  • "ecdsa_secp384r1_sha384" (default)
  • "ecdsa_secp521r1_sha512" (default)
  • "rsa_pkcs1_sha256" (default)

Socket Config Settings

AbsoluteTimeout:   Determines whether timeouts are inactivity timeouts or absolute timeouts.

If AbsoluteTimeout is set to True, any method which does not complete within Timeout seconds will be aborted. By default, AbsoluteTimeout is False, and the timeout is an inactivity timeout.

Note: This option is not valid for UDP ports.

FirewallData:   Used to send extra data to the firewall.

When the firewall is a tunneling proxy, use this property to send custom (additional) headers to the firewall (e.g. headers for custom authentication schemes).

InBufferSize:   The size in bytes of the incoming queue of the socket.

This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. Increasing the value of the InBufferSize setting can provide significant improvements in performance in some cases.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the InBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

OutBufferSize:   The size in bytes of the outgoing queue of the socket.

This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be sending. Increasing the value of the OutBufferSize setting can provide significant improvements in performance in some cases.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the OutBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.
