WSServer Class

Properties   Methods   Events   Config Settings   Errors  

The WSServer class is used to create a WebSocket server.

Syntax

ipworks.wsserver()

Remarks

The WSServer class functions as a server that facilitates incoming WebSocket connections and offers a convenient means of transmitting and receiving data over the established connections.

To start, the LocalPort property must be specified to a valid port. This port will be used to accept incoming connections. Then, call the StartListening method to start listening on the specified port. The WSServer class supports both plaintext and Secure Sockets Layer/Transport Layer Security (SSL/TLS) connections. The SSLStatus event provides information about the SSL handshake. Additional SSL related settings are also supported via the Config method. The SSLCert properties are used to select a certificate for the server. Note: A valid certificate MUST be selected before the server can function.

Upon a client's connection, the WebSocketOpenRequest event will be fired. To accept the connection, simply allow the event to complete its execution. Conversely, to reject the request, the StatusCode parameter can be set to an appropriate HTTP error code, such as 401.

By default, each instance of WSServer has the capacity to handle up to 1,000 simultaneous incoming connections. You can change the maximum number of simultaneous connections by adjusting the MaxConnections configuration setting. This setting allows you to increase the limit up to 100,000 or decrease it to a lower value based on your needs.

Each connection is identified by a unique ConnectionId, an identifier generated by the component to distinguish individual connections. The ConnectionId is also included as a parameter in WSServer's events to identify the associated connection.

After receiving a connection, incoming data can be accessed through the DataIn event. To transmit data to a client, the Send, SendText, or SendFile methods can be employed, or the ConnectionsDataToSend field can be set accordingly.

Note: Server components are designed to process events as they occur. To ensure that events are processed in a timely manner, DoEvents should be called in a loop after the server is started.

Config Settings

The following is a list of config settings for the class with short descriptions. Click on the links for further details.

WSServer.ConnectionBacklog Property

This property includes the maximum number of pending connections maintained by the Transmission Control Protocol (TCP)/IP subsystem.

Syntax

getConnectionBacklog(): number;
setConnectionBacklog(connectionBacklog: number): void;

Default Value

5

Remarks

This property contains the maximum number of pending connections maintained by the TCP/IP subsystem. This value reflects the SOMAXCONN option for the main listening socket. The default value for most systems is 5. You may set this property to a larger value if the server is expected to receive a large number of connections, and queuing them is desirable.

This property is not available at design time.

WSServer.Connections Property

A collection of currently connected WebSocket clients.

Syntax

getConnections(): WSConnectionMap;

Default Value

Remarks

This property contains a collection of currently connected clients. All of the connections may be managed using this property. Each connection is described by the different fields of the WSConnection type.

This collection is a hashtable type of collection, in which the Connection ID string is used as the key to the desired connection. You may acquire the key for a given connection through the Connected or WebSocketOpenRequest events.

This property is read-only.

WSServer.DefaultTimeout Property

An initial timeout value to be used by incoming connections.

Syntax

getDefaultTimeout(): number;
setDefaultTimeout(defaultTimeout: number): void;

Default Value

0

Remarks

This property is used by the class to set the operational timeout value of all inbound connections once they are established.

By default, the timeout is 0, meaning that all inbound connections will behave asynchronously.

WSServer.Listening Property

If set to True, the class accepts incoming connections on LocalPort.

Syntax

isListening(): boolean;

Default Value

FALSE

Remarks

This property indicates whether the class is listening for connections on the port specified by the LocalPort property.

Note: Use the StartListening and StopListening methods to control whether the class is listening.

This property is not available at design time.

WSServer.LocalHost Property

The name of the local host or user-assigned IP interface through which connections are initiated or accepted.

Syntax

getLocalHost(): string;
setLocalHost(localHost: string): void;

Default Value

""

Remarks

The LocalHost property 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 property 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).

NOTE: LocalHost is not persistent. You must always set it in code, and never in the property window.

WSServer.LocalPort Property

This property includes the Transmission Control Protocol (TCP) port in the local host where the class listens.

Syntax

getLocalPort(): number;
setLocalPort(localPort: number): void;

Default Value

0

Remarks

This property must be set before the class can start listening. If its value is 0, then the TCP/IP subsystem picks a port number at random. The port number can be found by checking the value of this property after the class is listening (i.e., after successfully assigning True to the Listening property).

The service port is not shared among servers so two classs cannot be listening on the same port at the same time.

WSServer.SSLAuthenticateClients Property

If set to True, the server asks the client(s) for a certificate.

Syntax

isSSLAuthenticateClients(): boolean;
setSSLAuthenticateClients(SSLAuthenticateClients: boolean): void;

Default Value

FALSE

Remarks

This property is used in conjunction with the SSLClientAuthentication event. Please refer to the documentation of the SSLClientAuthentication event for details.

WSServer.SSLCert Property

The certificate to be used during SSL negotiation.

Syntax

getSSLCert(): Certificate;
setSSLCert(SSLCert: Certificate): void;

Default Value

Remarks

The digital certificate that the class will use during SSL negotiation. Set this property to a valid certificate before starting SSL negotiation. To set a certificate, you may set the field to the encoded certificate. To select a certificate, use the store and subject fields.

WSServer.UseSSL Property

Determines if SSL is negotiated with incoming connections.

Syntax

isUseSSL(): boolean;
setUseSSL(useSSL: boolean): void;

Default Value

FALSE

Remarks

When set to True the class will attempt to negotiate SSL with all connecting clients. To enable SSL support you must supply a valid certificate via the SSLCertStoreType, SSLCertStore, SSLCertStorePassword, and SSLCertSubject properties

The default value is False.

This property is not available at design time.

WSServer.changeLineMode Method

Controls whether the class will fire DataIn when an EOL is received for the specified connection.

Syntax

async wsserver.changeLineMode(connectionId : string, lineMode : boolean): Promise<void>

Remarks

When ConnectionsLineMode is set to false (default), the component will fire the DataIn event once for each message received from the client. When LineMode is set to True, the component will instead fire DataIn for each line of data received. The maximum length of a line can be controlled by the MaxLineLength[ConnectionId]; configuration setting.

Note: This method is offered as a convenience feature, and has no effect on the behavior of the WebSocket protocol.

WSServer.config Method

Sets or retrieves a configuration setting.

Syntax

async wsserver.config(configurationString : string): Promise<string>

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.

WSServer.disconnect Method

This method disconnects the specified client.

Syntax

async wsserver.disconnect(connectionId : string): Promise<void>

Remarks

Calling this method will disconnect the client specified by the ConnectionId parameter.

WSServer.doEvents Method

Processes events from the internal message queue.

Syntax

async wsserver.doEvents(): Promise<void>

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.

WSServer.interrupt Method

Interrupts a synchronous send to the remote host.

Syntax

async wsserver.interrupt(connectionId : string): Promise<void>

Remarks

This property is called using the Connection ID if you wish to interrupt a connection and stop a file from uploading without disconnecting the client connected to the class. If you use SendFile to upload a file, the class will run synchronously on that Connection ID until it is completed.

WSServer.ping Method

Sends a Ping request to the remote host.

Syntax

async wsserver.ping(connectionId : string): Promise<void>

Remarks

This method sends a Ping request to the remote host and waits for a corresponding Pong response.

The Timeout property specifies how long to wait for the Pong response.

WSServer.send Method

Sends binary data to the client.

Syntax

async wsserver.send(connectionId : string, data : Uint8Array): Promise<void>

Remarks

This method sends the binary data specified by Data to the client specified by ConnectionId.

WSServer.sendBytes Method

This method sends binary data to the specified client.

Syntax

async wsserver.sendBytes(connectionId : string, data : Uint8Array): Promise<void>

Remarks

This method sends binary data to the client identified by ConnectionId. To send text, use the SendText method instead.

When ConnectionsTimeout is set to 0, the class will behave asynchronously. If you are sending data to the remote host faster than it can process it, or faster than the network's bandwidth allows, the outgoing queue might fill up. When this happens, the operation . The BytesSent property shows how many bytes were sent (if any). If 0 bytes were sent, then you can wait for the ReadyToSend event before attempting to send data again.

Note: The ReadyToSend event is not fired when part of the data is sent successfully.

This method sends binary data to the client identified by ConnectionId. To send text, use the SendText method instead.

When ConnectionsTimeout is set to 0, the class will behave asynchronously. If you are sending data to the remote host faster than it can process it, or faster than the network's bandwidth allows, the outgoing queue might fill up. When this happens, the operation . The BytesSent property shows how many bytes were sent (if any). If 0 bytes were sent, then you can wait for the ReadyToSend event before attempting to send data again.

Note: The ReadyToSend event is not fired when part of the data is sent successfully.

WSServer.sendFile Method

This method sends the file to the remote host.

Syntax

async wsserver.sendFile(connectionId : string, fileName : string): Promise<void>

Remarks

This method sends the file to the client specified by the ConnectionId.

WSServer.sendText Method

Sends text data to the client.

Syntax

async wsserver.sendText(connectionId : string, text : string): Promise<void>

Remarks

This method sends text to the client identified by ConnectionId. To send binary data, use the SendBytes method instead.

When ConnectionsTimeout is set to 0, the class will behave asynchronously. If you are sending data to the remote host faster than it can process it, or faster than the network's bandwidth allows, the outgoing queue might fill up. When this happens, the operation . The BytesSent property shows how many bytes were sent (if any). If 0 bytes were sent, then you can wait for the ReadyToSend event before attempting to send data again.

Note: The ReadyToSend event is not fired when part of the data is sent successfully.

This method sends text to the client identified by ConnectionId. Data sent with this method will always be treated as text data regardless of the value of ConnectionsDataFormat. The class will UTF-8 encode the supplied text.

WSServer.shutdown Method

This method shuts down the server.

Syntax

async wsserver.shutdown(): Promise<void>

Remarks

This method shuts down the server. Calling this method is equivalent to calling StopListening and then breaking every client connection by calling Disconnect.

WSServer.startListening Method

This method starts listening for incoming connections.

Syntax

async wsserver.startListening(): Promise<void>

Remarks

This method begins listening for incoming connections on the port specified by LocalPort. Once listening, events will fire as new clients connect and data are transferred.

To stop listening for new connections, call StopListening. To stop listening for new connections and to disconnect all existing clients, call Shutdown.

WSServer.stopListening Method

This method stops listening for new connections.

Syntax

async wsserver.stopListening(): Promise<void>

Remarks

This method stops listening for new connections. After being called, any new connection attempts will be rejected. Calling this method does not disconnect existing connections.

To stop listening and to disconnect all existing clients, call Shutdown instead.

WSServer.Connected Event

Fired when a WebSocket is successfully opened.

Syntax

wsserver.on('Connected', listener: (e: {readonly connectionId: string}) => void )

Remarks

The Connected event is fired when a WebSocket is successfully opened on a connection.

ConnectionId identifies the connection.

WSServer.ConnectionRequest Event

This event is fired when a request for connection comes from a remote host.

Syntax

wsserver.on('ConnectionRequest', listener: (e: {readonly address: string, readonly port: number, accept: boolean}) => void )

Remarks

This event indicates an incoming connection. The connection is accepted by default. Address and Port will contain information about the remote host requesting the inbound connection. If you want to refuse it, you can set the Accept parameter to False.

WSServer.DataIn Event

Fired when data is received.

Syntax

wsserver.on('DataIn', listener: (e: {readonly connectionId: string, readonly dataFormat: number, readonly text: string, readonly textB: Uint8Array, readonly EOM: boolean, readonly EOL: boolean}) => void )

Remarks

The DataIn event provides the data received from the client identified by the ConnectionId parameter.

The incoming data is provided through the Text parameter.

The DataFormat parameter identifies the encoding (if any) of the data. Possible value are:

The EOM parameter stands for End Of Message. By default the class will fire the DataIn event as data is received. Larger messages will be fragmented and will cause the event to fire multiple times. When EOM is true within the event this indicates the current fragment is also the final fragment of the message. The class may also be configured to buffer the message internally until the complete message is received. To enable this set BufferMessage to true.

The EOL parameter stands for End of Line. When LineMode is false, EOL will always be false. When LineMode is true, EOL will be True if the DataIn event fired because an EOL was received, and false if the DataIn event fired because MaxLineLength was reached.

WSServer.Disconnected Event

Fired when a WebSocket connection is disconnected.

Syntax

wsserver.on('Disconnected', listener: (e: {readonly connectionId: string, readonly statusCode: number, readonly description: string}) => void )

Remarks

When the connection is closed the StatusCode parameter may be used to determine if the disconnect occurred normally or if there was an error condition. If the connection is closed normally the StatusCode will be 1000. The Description parameter will contain a textual description returned by the server. Common StatusCode values are:

WSServer.Error Event

Information about errors during data delivery.

Syntax

wsserver.on('Error', listener: (e: {readonly connectionId: string, readonly errorCode: number, readonly description: string}) => void )

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the class .

ConnectionId contains an error code and Description contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

ErrorCode contains an error code and Description contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

WSServer.Log Event

Fires once for each log message.

Syntax

wsserver.on('Log', listener: (e: {readonly connectionId: string, readonly logLevel: number, readonly message: string, readonly logType: string}) => void )

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 message. Possible values are:

The value 1 (Info) logs basic information including the URL, HTTP version, and connection status details.

The value 2 (Verbose) logs additional information about the initial HTTP request.

The value 3 (Debug) logs additional debug information (if available).

Message is the log entry.

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

• "Info"
• "Error"
• "Verbose"
• "Debug"

WSServer.Ping Event

Fired when a ping request or response is received.

Syntax

wsserver.on('Ping', listener: (e: {readonly connectionId: string, readonly payload: string, readonly payloadB: Uint8Array, readonly response: boolean}) => void )

Remarks

This event fires when a ping request or response is received from the client identified by the ConnectionId parameter. This event is informational only. When the class receives a ping request it will automatically reply with a pong.

Payload holds the payload of the request, if any.

Response is true if the incoming packet is a ping response. If the incoming packet is a ping request this is false.

WSServer.ReadyToSend Event

This event is fired when the class is ready to send data.

Syntax

wsserver.on('ReadyToSend', listener: (e: {readonly connectionId: string}) => void )

Remarks

The ReadyToSend event indicates that the underlying Transmission Control Protocol (TCP)/IP subsystem is ready to accept data after a failed DataToSend. This event is also fired immediately after a connection is established.

WSServer.SSLClientAuthentication Event

This event is fired when the client presents its credentials to the server.

Syntax

wsserver.on('SSLClientAuthentication', listener: (e: {readonly connectionId: string, readonly certEncoded: string, readonly certEncodedB: Uint8Array, readonly certSubject: string, readonly certIssuer: string, readonly status: string, accept: boolean}) => void )

Remarks

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

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string "OK").

WSServer.SSLConnectionRequest Event

This event fires when a Secure Sockets Layer (SSL) connection is requested.

Syntax

wsserver.on('SSLConnectionRequest', listener: (e: {readonly connectionId: string, readonly supportedCipherSuites: string, readonly supportedSignatureAlgs: string, certStoreType: number, certStore: string, certPassword: string, certSubject: string}) => void )

Remarks

This event fires when an SSL connection is requested and SSLProvider is set to Internal. This event provides an opportunity to select an alternative certificate to the connecting client. This event does not fire when SSLProvider is set to Platform.

This event allows the class to be configured to use both RSA and ECDSA certificates depending on the connecting client's capabilities.

ConnectionId is the connection Id of the client requesting the connection.

SupportedCipherSuites is a comma-separated list of cipher suites that the client supports.

SupportedSignatureAlgs is a comma-separated list of certificate signature algorithms that the client supports.

CertStoreType is the store type of the alternate certificate to use for this connection. The class supports both public and private keys in a variety of formats. When the cstAuto value is used the class will automatically determine the type. This property can take one of the following values:

CertStore is the store name or location of the alternate certificate to use for this connection.

Designations of certificate stores are platform-dependent.

The following are designations of the most common User and Machine certificate stores in Windows:

When the certificate store type is PFXFile, this property must be set to the name of the file. When the type is PFXBlob, the property must be set to the binary contents of a PFX file (i.e. PKCS12 certificate store).

CertPassword is the password of the certificate store containing the alternate certificate to use for this connection.

CertSubject is the subject of the alternate certificate to use for this connection.

The special value * matches any subject and will select the first certificate in the 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.

If a field value contains a comma it must be quoted.

WSServer.SSLStatus Event

This event is fired to show the progress of the secure connection.

Syntax

wsserver.on('SSLStatus', listener: (e: {readonly connectionId: string, readonly message: string}) => void )

Remarks

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

WSServer.WebSocketOpenRequest Event

Fired when a client attempts to open a WebSocket.

Syntax

wsserver.on('WebSocketOpenRequest', listener: (e: {readonly connectionId: string, readonly requestURI: string, readonly hostHeader: string, readonly originHeader: string, subProtocols: string, readonly extensions: string, readonly requestHeaders: string, statusCode: number, responseHeaders: string}) => void )

Remarks

This event fires when a client connects. It provides an opportunity to inspect the WebSocket request and either accept or reject the connection attempt.

By default, the class will accept the connection. You do not need to set anything to accept the connection. The class will return a StatusCode of 101 to the connecting client and the request will proceed as normal. To reject a connection, set StatusCode to an HTTP error code, such as 401.

ConnectionId identifies the connecting client.

RequestURI provides the URI requested by the connecting client. This may be used to implement logic to select appropriate SubProtocols or determine if the connection should be accepted based on access restrictions to the URI.

HostHeader holds the value of the Host header sent by the client.

OriginHeader holds the value of the Origin header sent by the client.

SubProtocols holds a comma separated list of subprotocols sent by the client (if any). Set SubProtocols to the selected value from the list sent by the client. The class will return this value to the client as the subprotocol the server has selected.

Extensions provides a list of extensions supported by the client.

RequestHeaders contains the HTTP headers sent in the request by the connecting client.

StatusCode determines success or failure. The value 101 (default) indicates success. This may be set to any HTTP status code. For instance a value of 401 indicates an authorization failure.

ResponseHeaders may be set to include additional headers in the response. This is typically used when rejecting a request. For instance when StatusCode is set to 401 you might set ResponseHeaders to "WWW-Authenticate: Basic realm="Secure Realm"" to request authorization from the connecting client.

Certificate Type

This is the digital certificate being used.

Remarks

This type describes the current digital certificate. The certificate may be a public or private key. The fields are used to identify or select certificates.

Fields

Constructors

public Certificate();

Creates a Certificate instance whose properties can be set. This is useful for use with CERTMGR when generating new certificates.

public Certificate(String certificateFile);

Opens CertificateFile and reads out the contents as an X509 public key.

public Certificate(byte[] certificateData);

Parses CertificateData as an X509 public key.

public Certificate(int certStoreType, String store, String storePassword, String subject);

CertStoreType identifies the type of certificate store to use. See StoreType for descriptions of the different certificate stores. Store is a file containing the certificate store. StorePassword is the password used to protect the store. After the store has been successfully opened, the class will attempt to find the certificate identified by Subject . This can be either a complete or a substring match of the X509 certificate's subject Distinguished Name (DN).

public Certificate(int certStoreType, String store, String storePassword, String subject, String configurationString);

CertStoreType identifies the type of certificate store to use. See StoreType for descriptions of the different certificate stores. Store is a file containing the certificate store. StorePassword is the password used to protect the store. ConfigurationString is a newline separated list of name-value pairs that may be used to modify the default behavior. Possible values include "PersistPFXKey", which shows whether or not the PFX key is persisted after performing operations with the private key. This correlates to the PKCS12_NO_PERSIST_KEY CyrptoAPI option. The default value is True (the key is persisted). "Thumbprint" - a MD5, SHA1, or SHA256 thumbprint of the certificate to load. When specified, this value is used to select the certificate in the store. This is applicable to cstUser, cstMachine, cstPublicKeyFile, and cstPFXFile store types. "UseInternalSecurityAPI" shows whether the platform (default) or the internal security API is used when performing certificate-related operations. After the store has been successfully opened, the class will attempt to find the certificate identified by Subject . This can be either a complete or a substring match of the X509 certificate's subject Distinguished Name (DN).

public Certificate(int certStoreType, String store, String storePassword, byte[] encoded);

CertStoreType identifies the type of certificate store to use. See StoreType for descriptions of the different certificate stores. Store is a file containing the certificate store. StorePassword is the password used to protect the store. After the store has been successfully opened, the class will load Encoded as an X509 certificate and search the opened store for a corresponding private key.

public Certificate(int certStoreType, byte[] storeBlob, String storePassword, String subject);

CertStoreType identifies the type of certificate store to use. See StoreType for descriptions of the different certificate stores. StoreBlob is a string (binary- or base64-encoded) containing the certificate data. StorePassword is the password used to protect the store. After the store has been successfully opened, the class will attempt to find the certificate identified by Subject . This can be either a complete or a substring match of the X509 certificate's subject Distinguished Name (DN).

public Certificate(int certStoreType, byte[] storeBlob, String storePassword, String subject, String configurationString);

CertStoreType identifies the type of certificate store to use. See StoreType for descriptions of the different certificate stores. StoreBlob is a string (binary- or base64-encoded) containing the certificate data. StorePassword is the password used to protect the store. After the store has been successfully opened, the class will attempt to find the certificate identified by Subject . This can be either a complete or a substring match of the X509 certificate's subject Distinguished Name (DN).

public Certificate(int certStoreType, byte[] storeBlob, String storePassword, byte[] encoded);

CertStoreType identifies the type of certificate store to use. See StoreType for descriptions of the different certificate stores. Store is a string (binary- or base64-encoded) containing the certificate store. StorePassword is the password used to protect the store. After the store has been successfully opened, the class will load Encoded as an X509 certificate and search the opened store for a corresponding private key.
