The AS4Client control connects to a server to send or receive files.

Syntax

AS4Client

Remarks

The AS4Client component may be used to send or receive files from a server. The component will connect to a server and either send files (push), or request files to download (pull).

Sending Files

SendFiles sends the files specified by EDIData to URL.

Before calling this method set AgreementRef to the agreement identifier used by both parties. Set AS4From and AS4To. Set EDIData specifies the file(s) to be sent. To encrypt the data set RecipientCerts. To sign the data set SigningCert. The SignerCert property should be set to verify the signed receipt.

When this method is called the file(s) will be sent and any returned receipts will be verified.

To indicate a synchronous receipt is expected set ReceiptReplyMode to rrmSync. The following properties are applicable when calling this method with an agreement specifying a synchronous receipt (a receipt provided in the response):

• AgreementRef
• AS4From
• AS4To
• EDIData
• URL
• RecipientCerts (required to encrypt)
• SignerCert (required to verify signed receipts)
• SigningCert (required to sign files)
• ConversationId (optional)
• EncryptionAlgorithm (optional)
• LogDirectory (optional)
• MessageId (optional)
• MessageProperties (optional)
• Profile (optional)
• ReceiptReplyMode
• Service (optional)
• ServiceType (optional)
• SignatureAlgorithm (optional)

SendFiles Example (synchronous receipt): client.Profile = As4clientProfiles.ebpfENTSOG; //Specify the agreement and party information client.AgreementRef = "http://agreements.company.com/sign_and_encrypt"; client.AS4From.Role = "Sender"; client.AS4From.Id = "org:b2b:example:company:A"; client.AS4To.Role = "Receiver"; client.AS4To.Id = "org:b2b:example:company:B"; //Configure the component to expect a synchronous receipt. client.ReceiptReplyMode = As4clientReceiptReplyModes.rrmSync; //Company A's private certificate. Used to sign the outgoing message and files. client.SigningCert = new Certificate(CertStoreTypes.cstPFXFile, "C:\\files\\CompanyA.pfx", "password", "*"); //Company B's public certificate. Used to encrypt the outgoing file. client.RecipientCerts.Add(new Certificate("C:\\files\\as4\\CompanyB.cer")); //Company B's public certificate. Used to verify the signed receipt. client.SignerCert = new Certificate("C:\\files\\as4\\CompanyB.cer"); client.URL = "http://www.company.com:9090/msh"; EBData data = new EBData(); data.EDIType = "application/edi-x12"; data.Filename = "C:\\files\\myfile.x12"; data.Name = "myfile.x12"; client.EDIData.Add(data); //Send file(s) and verify the receipt. client.SendFiles();

The control also supports asynchronous receipts. In this configuration a file is sent from the control to another party, but the receipt is not returned in the response. Instead the other party sends the receipt at a later time. The AS4Server control may be used inside a web page to receive the asynchronous receipt. After receiving the receipt either AS4Server or AS4Client may be used to verify the receipt.

Details about the original message must be stored so that the receipt can be correlated with the message and properly verified. The easiest way to do this is to set AsyncReceiptInfoDir before calling SendFiles. The control will automatically store the required information.

See the VerifyReceipt method of AS4Server for details about verifying asynchronous receipts.

To indicate an asynchronous receipt is expected set ReceiptReplyMode to rrmAsync. The following properties are applicable when calling this method with an agreement specifying a synchronous receipt (a receipt provided in the response):

• AgreementRef
• AS4From
• AS4To
• AsyncReceiptInfoDir
• EDIData
• URL
• RecipientCerts (required to encrypt)
• SignerCert (required to verify signed receipts)
• SigningCert (required to sign files)
• ConversationId (optional)
• EncryptionAlgorithm (optional)
• LogDirectory (optional)
• MessageId (optional)
• MessageProperties (optional)
• OriginalSOAPMessage (optional)
• OriginalSOAPMessageId (optional)
• Profile (optional)
• ReceiptReplyMode
• Service (optional)
• ServiceType (optional)
• SignatureAlgorithm (optional)

SendFiles Example (asynchronous receipt): client.Profile = As4clientProfiles.ebpfENTSOG; //Specify the agreement and party information client.AgreementRef = "http://agreements.company.com/sign_and_encrypt_async"; client.AS4From.Role = "Sender"; client.AS4From.Id = "org:b2b:example:company:A"; client.AS4To.Role = "Receiver"; client.AS4To.Id = "org:b2b:example:company:B"; //Configure the component to expect a synchronous receipt. client.ReceiptReplyMode = As4clientReceiptReplyModes.rrmAsync; client.AsyncReceiptInfoDir = "C:\\async_info"; //Company A's private certificate. Used to sign the outgoing message and files. client.SigningCert = new Certificate(CertStoreTypes.cstPFXFile, "C:\\files\\CompanyA.pfx", "password", "*"); //Company B's public certificate. Used to encrypt the outgoing files. client.RecipientCerts.Add(new Certificate("C:\\files\\as4\\CompanyB.cer")); //Company B's public certificate. Used to verify the signed receipt. client.SignerCert = new Certificate("C:\\files\\as4\\CompanyB.cer"); client.URL = "http://www.company.com:9090/msh"; EBData data = new EBData(); data.EDIType = "application/edi-x12"; data.Filename = "C:\\files\\myfile.x12"; data.Name = "myfile.x12"; client.EDIData.Add(data); //Send file(s). client.SendFiles();

At this point the file(s) have been sent, but a receipt has not yet been received. AS4Server can be used within a web site to listen for the receipt. //**** Inside a web site **** As4server server = new As4server; server.ReadRequest(); if (!String.IsNullOrEmpty(server.IncomingReceipt.Content)) { server.AsyncReceiptInfoDir = "C:\\async_info"; server.VerifyReceipt(); //The receipt is now verified }

Receiving Files

ReceiveFiles establishes a connection to the server specified by URL and receives files.

The MPC specifies the Message Partition Channel from which messages will be received. The server will reply with files from this channel. If IncomingDirectory is set before calling this method the files will be written to the specified folder, otherwise inspect EDIData to obtain the received file data. The following properties are applicable when calling this method:

• SigningCert (required to sign the request)
• Certificate (required for decryption)
• SignerCert (required for signature verification)
• URL
• IncomingDirectory (optional)
• LogDirectory
• MPC
• TokenUser
• TokenPassword
• TokenPasswordType

• AS4From
• AS4To
• AgreementRef
• ConversationId
• Service
• ServiceAction
• ServiceType
• MessageId
• Receipt

To bundle the receipt with a subsequent ReceiveFiles call the Receipt property must hold the receipt. If the same instance of the control is being used this is already true since Receipt is populated automatically after receiving the file. To use another instance of the control for multiple calls to ReceiveFiles be sure to save the Receipt's ReceiptContent and ReceiptRefToMessageId values for later use.

ReceiveFiles Example: client.Profile = As4clientProfiles.ebpfENTSOG; //Company A's private certificate. Used for signing the request. client.SigningCert = new Certificate(CertStoreTypes.cstPFXFile, "C:\\files\\as4\\CompanyA.pfx", "password", "*"); //Company A's private certificate. Used for decrypting the file. client.Certificate = new Certificate(CertStoreTypes.cstPFXFile, "C:\\files\\as4\\CompanyA.pfx", "password", "*"); //Company B's public certificate. Used for signature verification. client.SignerCert = new Certificate("C:\\files\\as4\\CompanyB.cer"); client.URL = "http://www.company.com:9090/msh"; //Message Channel id client.MPC = "mpc_a"; client.IncomingDirectory = "C:\\incoming_dir"; client.ReceiveFiles(); //Inspect client.AgreementRef and other properties for information about the received files Console.WriteLine(client.AgreementRef); Console.WriteLine(client.AS4From.Id); Console.WriteLine(client.AS4To.Id); Console.WriteLine(client.ConversationId); //Save the receipt for later use string receiptContent = client.Receipt.Content; string receiptRefId = client.Receipt.RefToMessageId;

At this stage the receipt data is saved. Later when making another call to ReceiveFiles and populate the Receipt property with this receipt data. When ReceiveFiles is called again, the receipt for the previous message will be included with the request. client.Receipt = new EBReceipt(receiptRefId, receiptContent); client.ReceiveFiles(); //This will now include the bundled receipt

Sending Asynchronous Receipts

SendReceipt sends an asynchronous receipt to the URL.

This method is typically used in conjunction with AS4Server to send an asynchronous receipt after receiving a message. The receipt will be created at the time of the incoming request, then saved for later use. When the receipt is to be sent populate Receipt and call this method.

//Send an asynchronous receipt client.URL = ""http://www.company.com:9090/msh""; client.Receipt = new EBReceipt(server.Receipt.RefToMessageId, server.Receipt.Content); client.ReceiptReplyMode = As4clientReceiptReplyModes.rrmAsync; client.SendReceipt();

Each file may contain zero or more properties associated with it. This property, in conjunction with EDIPropertyIndex, EDIPropertyName, and EDIPropertyValue can be used to specify properties when sending and read properties when receiving.

Sending

When sending files to add properties set EDIPropertyCount to specify the number of properties. Then set EDIPropertyIndex to select the property. Set EDIPropertyName and EDIPropertyValue to define the values for the property at EDIPropertyIndex. For instance: data = new EBData(); data.EDIType = "image/jpeg"; data.Filename = "..\\1.jpg"; data.Name = "1.jpg"; data.PropertyCount = 2; //Define two properties data.PropertyIndex = 0; //Select the first property data.PropertyName = "name1"; data.PropertyValue = "value1"; data.PropertyIndex = 1; //Select the second property data.PropertyName = "name2"; data.PropertyValue = "value2";

Receiving

When receiving files these properties may be queried to retrieve the values set by the sender. Inspect EDIPropertyCount to obtain the number of properties. Next set EDIPropertyIndex to select a property and query EDIPropertyName and EDIPropertyValue. For instance:

for (int i = 0; i < server.EDIData[0].PropertyCount;i++) { server.EDIData[0].PropertyIndex = i; Console.WriteLine(server.EDIData[0].PropertyName + ": " + server.EDIData[0].PropertyValue); }

A timeout for the control.

Syntax

as4clientcontrol.Timeout[=integer]

Default Value

60

Remarks

If the Timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.

If Timeout is set to a positive value, the control will wait for the operation to complete before returning control.

The control 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 control 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.

Syntax

as4clientcontrol.TokenPassword[=string]

Default Value

""

Remarks

This property specifies the password used in UsernameToken authentication.

UsernameToken Authentication Notes

If TokenUser and TokenPassword are specified the control will include UsernameToken authentication when ReceiveFiles is called. This functionality is only applicable when calling ReceiveFiles.

TokenPassword should normally be set to the plaintext password that both the client and server know. The control will automatically use SHA-1 to create a hash of the password when TokenPasswordType is set to tptDigest (default). The hashed password is sent in the request, along with a creation date and nonce. The server will validate these values when receiving the request.

client.TokenUser = "User"; client.TokenPassword = "MyPassword"; client.TokenPasswordType = As4clientTokenPasswordTypes.tptDigest; client.ReceiveFiles();

A creation date element is always sent in the request. A nonce is sent by default but can be disabled by setting UseNonce to False.

If TokenPasswordType is set to tptText the control will transmit value provided in TokenPassword exactly as it is provided. The value will not be hashed. This may be useful in cases where an alternative credential mechanism is used between the client and server.

Data Type

String

Remarks

This property specifies the URL to which the request is made. SSL will be used if and only if the URL scheme is "https".

Data Type

String

Config Method (AS4Client Control)

Sets or retrieves a configuration setting.

Syntax

as4clientcontrol.Config ConfigurationString

Remarks

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

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the control, 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.

DoEvents Method (AS4Client Control)

Processes events from the internal message queue.

Syntax

as4clientcontrol.DoEvents 

Remarks

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

Interrupt Method (AS4Client Control)

Interrupt the current method.

Syntax

as4clientcontrol.Interrupt 

Remarks

If there is no method in progress, Interrupt simply returns, doing nothing.

ReceiveFiles Method (AS4Client Control)

Connects to a server to receive files.

Syntax

as4clientcontrol.ReceiveFiles 

Remarks

ReceiveFiles establishes a connection to the server specified by URL and receives files.

The MPC specifies the Message Partition Channel from which messages will be received. The server will reply with files from this channel. If IncomingDirectory is set before calling this method the files will be written to the specified folder, otherwise inspect EDIData to obtain the received file data. The following properties are applicable when calling this method:

• SigningCert (required to sign the request)
• Certificate (required for decryption)
• SignerCert (required for signature verification)
• URL
• IncomingDirectory (optional)
• LogDirectory
• MPC
• TokenUser
• TokenPassword
• TokenPasswordType

• AS4From
• AS4To
• AgreementRef
• ConversationId
• Service
• ServiceAction
• ServiceType
• MessageId
• Receipt

To bundle the receipt with a subsequent ReceiveFiles call the Receipt property must hold the receipt. If the same instance of the control is being used this is already true since Receipt is populated automatically after receiving the file. To use another instance of the control for multiple calls to ReceiveFiles be sure to save the Receipt's ReceiptContent and ReceiptRefToMessageId values for later use.

ReceiveFiles Example: client.Profile = As4clientProfiles.ebpfENTSOG; //Company A's private certificate. Used for signing the request. client.SigningCert = new Certificate(CertStoreTypes.cstPFXFile, "C:\\files\\as4\\CompanyA.pfx", "password", "*"); //Company A's private certificate. Used for decrypting the file. client.Certificate = new Certificate(CertStoreTypes.cstPFXFile, "C:\\files\\as4\\CompanyA.pfx", "password", "*"); //Company B's public certificate. Used for signature verification. client.SignerCert = new Certificate("C:\\files\\as4\\CompanyB.cer"); client.URL = "http://www.company.com:9090/msh"; //Message Channel id client.MPC = "mpc_a"; client.IncomingDirectory = "C:\\incoming_dir"; client.ReceiveFiles(); //Inspect client.AgreementRef and other properties for information about the received files Console.WriteLine(client.AgreementRef); Console.WriteLine(client.AS4From.Id); Console.WriteLine(client.AS4To.Id); Console.WriteLine(client.ConversationId); //Save the receipt for later use string receiptContent = client.Receipt.Content; string receiptRefId = client.Receipt.RefToMessageId;

At this stage the receipt data is saved. Later when making another call to ReceiveFiles and populate the Receipt property with this receipt data. When ReceiveFiles is called again, the receipt for the previous message will be included with the request. client.Receipt = new EBReceipt(receiptRefId, receiptContent); client.ReceiveFiles(); //This will now include the bundled receipt

Reset Method (AS4Client Control)

Resets the state of the control.

Syntax

as4clientcontrol.Reset 

Remarks

Reset resets the state of the control. All properties will be set to their default values.

SendFiles Method (AS4Client Control)

Sends file(s) to the specified server and verify the receipt (if present).

Syntax

as4clientcontrol.SendFiles 

Remarks

SendFiles sends the files specified by EDIData to URL.

Before calling this method set AgreementRef to the agreement identifier used by both parties. Set AS4From and AS4To. Set EDIData specifies the file(s) to be sent. To encrypt the data set RecipientCerts. To sign the data set SigningCert. The SignerCert property should be set to verify the signed receipt.

When this method is called the file(s) will be sent and any returned receipts will be verified.

To indicate a synchronous receipt is expected set ReceiptReplyMode to rrmSync. The following properties are applicable when calling this method with an agreement specifying a synchronous receipt (a receipt provided in the response):

• AgreementRef
• AS4From
• AS4To
• EDIData
• URL
• RecipientCerts (required to encrypt)
• SignerCert (required to verify signed receipts)
• SigningCert (required to sign files)
• ConversationId (optional)
• EncryptionAlgorithm (optional)
• LogDirectory (optional)
• MessageId (optional)
• MessageProperties (optional)
• Profile (optional)
• ReceiptReplyMode
• Service (optional)
• ServiceType (optional)
• SignatureAlgorithm (optional)

SendFiles Example (synchronous receipt): client.Profile = As4clientProfiles.ebpfENTSOG; //Specify the agreement and party information client.AgreementRef = "http://agreements.company.com/sign_and_encrypt"; client.AS4From.Role = "Sender"; client.AS4From.Id = "org:b2b:example:company:A"; client.AS4To.Role = "Receiver"; client.AS4To.Id = "org:b2b:example:company:B"; //Configure the component to expect a synchronous receipt. client.ReceiptReplyMode = As4clientReceiptReplyModes.rrmSync; //Company A's private certificate. Used to sign the outgoing message and files. client.SigningCert = new Certificate(CertStoreTypes.cstPFXFile, "C:\\files\\CompanyA.pfx", "password", "*"); //Company B's public certificate. Used to encrypt the outgoing file. client.RecipientCerts.Add(new Certificate("C:\\files\\as4\\CompanyB.cer")); //Company B's public certificate. Used to verify the signed receipt. client.SignerCert = new Certificate("C:\\files\\as4\\CompanyB.cer"); client.URL = "http://www.company.com:9090/msh"; EBData data = new EBData(); data.EDIType = "application/edi-x12"; data.Filename = "C:\\files\\myfile.x12"; data.Name = "myfile.x12"; client.EDIData.Add(data); //Send file(s) and verify the receipt. client.SendFiles();

The control also supports asynchronous receipts. In this configuration a file is sent from the control to another party, but the receipt is not returned in the response. Instead the other party sends the receipt at a later time. The AS4Server control may be used inside a web page to receive the asynchronous receipt. After receiving the receipt either AS4Server or AS4Client may be used to verify the receipt.

Details about the original message must be stored so that the receipt can be correlated with the message and properly verified. The easiest way to do this is to set AsyncReceiptInfoDir before calling SendFiles. The control will automatically store the required information.

See the VerifyReceipt method of AS4Server for details about verifying asynchronous receipts.

To indicate an asynchronous receipt is expected set ReceiptReplyMode to rrmAsync. The following properties are applicable when calling this method with an agreement specifying a synchronous receipt (a receipt provided in the response):

• AgreementRef
• AS4From
• AS4To
• AsyncReceiptInfoDir
• EDIData
• URL
• RecipientCerts (required to encrypt)
• SignerCert (required to verify signed receipts)
• SigningCert (required to sign files)
• ConversationId (optional)
• EncryptionAlgorithm (optional)
• LogDirectory (optional)
• MessageId (optional)
• MessageProperties (optional)
• OriginalSOAPMessage (optional)
• OriginalSOAPMessageId (optional)
• Profile (optional)
• ReceiptReplyMode
• Service (optional)
• ServiceType (optional)
• SignatureAlgorithm (optional)

SendFiles Example (asynchronous receipt): client.Profile = As4clientProfiles.ebpfENTSOG; //Specify the agreement and party information client.AgreementRef = "http://agreements.company.com/sign_and_encrypt_async"; client.AS4From.Role = "Sender"; client.AS4From.Id = "org:b2b:example:company:A"; client.AS4To.Role = "Receiver"; client.AS4To.Id = "org:b2b:example:company:B"; //Configure the component to expect a synchronous receipt. client.ReceiptReplyMode = As4clientReceiptReplyModes.rrmAsync; client.AsyncReceiptInfoDir = "C:\\async_info"; //Company A's private certificate. Used to sign the outgoing message and files. client.SigningCert = new Certificate(CertStoreTypes.cstPFXFile, "C:\\files\\CompanyA.pfx", "password", "*"); //Company B's public certificate. Used to encrypt the outgoing files. client.RecipientCerts.Add(new Certificate("C:\\files\\as4\\CompanyB.cer")); //Company B's public certificate. Used to verify the signed receipt. client.SignerCert = new Certificate("C:\\files\\as4\\CompanyB.cer"); client.URL = "http://www.company.com:9090/msh"; EBData data = new EBData(); data.EDIType = "application/edi-x12"; data.Filename = "C:\\files\\myfile.x12"; data.Name = "myfile.x12"; client.EDIData.Add(data); //Send file(s). client.SendFiles();

At this point the file(s) have been sent, but a receipt has not yet been received. AS4Server can be used within a web site to listen for the receipt. //**** Inside a web site **** As4server server = new As4server; server.ReadRequest(); if (!String.IsNullOrEmpty(server.IncomingReceipt.Content)) { server.AsyncReceiptInfoDir = "C:\\async_info"; server.VerifyReceipt(); //The receipt is now verified }

SendReceipt Method (AS4Client Control)

Sends an asynchronous receipt.

Syntax

as4clientcontrol.SendReceipt 

Remarks

SendReceipt sends an asynchronous receipt to the URL.

This method is typically used in conjunction with AS4Server to send an asynchronous receipt after receiving a message. The receipt will be created at the time of the incoming request, then saved for later use. When the receipt is to be sent populate Receipt and call this method.

//Send an asynchronous receipt client.URL = ""http://www.company.com:9090/msh""; client.Receipt = new EBReceipt(server.Receipt.RefToMessageId, server.Receipt.Content); client.ReceiptReplyMode = As4clientReceiptReplyModes.rrmAsync; client.SendReceipt();

Connected Event (AS4Client Control)

This event is fired immediately after a connection completes (or fails).

Syntax

Sub as4clientcontrol_Connected(StatusCode As Integer, Description As String)

Remarks

If the connection is made normally, StatusCode is 0 and Description is "OK".

If the connection fails, StatusCode has the error code returned by the Transmission Control Protocol (TCP)/IP stack. Description contains a description of this code. The value of StatusCode is equal to the value of the error. The corresponding Visual Basic error code can be obtained by adding 15001 to this value.

Please refer to the Error Codes section for more information.

Disconnected Event (AS4Client Control)

This event is fired when a connection is closed.

Syntax

Sub as4clientcontrol_Disconnected(StatusCode As Integer, Description As String)

Remarks

If the connection is broken normally, StatusCode is 0 and Description is "OK".

If the connection is broken for any other reason, StatusCode has the error code returned by the Transmission Control Protocol (TCP/IP) subsystem. Description contains a description of this code. The value of StatusCode is equal to the value of the TCP/IP error. The corresponding Visual Basic error code can be obtained by adding 15001 to this value.

Please refer to the Error Codes section for more information.

EndTransfer Event (AS4Client Control)

This event is fired when a document finishes transferring.

Syntax

Sub as4clientcontrol_EndTransfer(Direction As Integer)

Remarks

The EndTransfer event is fired first when the client finishes sending data to the server (in a POST or PUT request) and then when the document text finishes transferring from the server to the local host.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

Error Event (AS4Client Control)

Fired when information is available about errors during data delivery.

Syntax

Sub as4clientcontrol_Error(ErrorCode As Integer, Description As String)

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the control fails with an error.

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

The Error event is fired in case of exceptional conditions during message processing. Normally the control fails with an error.

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

Header Event (AS4Client Control)

This event is fired every time a header line comes in.

Syntax

Sub as4clientcontrol_Header(Field As String, Value As String)

Remarks

The Field parameter contains the name of the HTTP header (which is the same as it is delivered). The Value parameter contains the header contents.

If the header line being retrieved is a continuation header line, then the Field parameter contains "" (empty string).

Log Event (AS4Client Control)

Fired with log information while processing a message.

Syntax

Sub as4clientcontrol_Log(LogType As String, LogMessage As String)

Remarks

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

Log messages available through this event correspond to log files written to LogDirectory. This event provides a way to obtain log messages without relying on files on disk. This event fires regardless of the value of LogDirectory (i.e. when LogDirectory is empty the event will still fire).

The LogMessage event parameter holds the raw log data.

The LogType event parameter indicates the type of log. Possible values are:

RecipientInfo Event (AS4Client Control)

Fired for each recipient certificate of the encrypted message.

Syntax

Sub as4clientcontrol_RecipientInfo(Issuer As String, SerialNumber As String, SubjectKeyIdentifier As String, EncryptionAlgorithm As String)

Remarks

When ParseRequest is called and the file is encrypted, this event will fire for each recipient certificate for which the file was encrypted.

Issuer is the subject of the issuer certificate.

SerialNumber is the serial number of the encryption certificate.

SubjectKeyIdentifier is the X.509 subjectKeyIdentifier extension value of the certificate used to sign the message encoded as a hex string.

EncryptionAlgorithm is the encryption algorithm used to encrypt the message. Possible values are as follows:

• "3DES"
• "DES"
• "RC2CBC40"
• "RC2CBC64"
• "RC2CBC128" or "RC2"
• "AESCBC128" or "AES"
• "AESCBC192"
• "AESCBC256"
• "AESGCM128" or "AESGCM"
• "AESGCM192"
• "AESGCM256"

SetCookie Event (AS4Client Control)

This event is fired for every cookie set by the server.

Syntax

Sub as4clientcontrol_SetCookie(Name As String, Value As String, Expires As String, Domain As String, Path As String, Secure As Boolean)

Remarks

The SetCookie event is fired for every Set-Cookie: header received from the HTTP server.

The Name parameter contains the name of the cookie, with the corresponding value supplied in the Value parameter.

The Expires parameter contains an expiration time for the cookie (if provided by the server). The time format used is "Weekday, DD-Mon-YY HH:MM:SS GMT". If the server does not provide an expiration time, the Expires parameter will be an empty string. In this case, the convention is to drop the cookie at the end of the session.

The Domain parameter contains a domain name to limit the cookie to (if provided by the server). If the server does not provide a domain name, the Domain parameter will be an empty string. The convention in this case is to use the server specified in the URL (URLServer) as the cookie domain.

The Path parameter contains a path name to limit the cookie to (if provided by the server). If the server does not provide a cookie path, the Path parameter will be an empty string. The convention in this case is to use the path specified in the URL (URLPath) as the cookie path.

The Secure parameter specifies whether the cookie is secure. If the value of this parameter is True, the cookie value must be submitted only through a secure (HTTPS) connection.

SignerCertInfo Event (AS4Client Control)

This event is fired during verification of the signed message.

Syntax

Sub as4clientcontrol_SignerCertInfo(Issuer As String, SerialNumber As String, SubjectKeyIdentifier As String, CertEncoded As String)

Remarks

During verification, this event will be raised while parsing the signer's certificate information. The parameters that are populated depend on the options used when the message was originally signed. This information may be used to select the correct certificate for SignerCert to verify the signature. The following parameters may be populated:

Issuer specifies the subject of the issuer of the certificate used to sign the message.

SerialNumber is the serial number of the certificate used to sign the message.

SubjectKeyIdentifier is the X.509 subjectKeyIdentifier extension value of the certificate used to sign the message encoded as a hex string.

CertEncoded is the PEM (Base64 encoded) public certificate needed to verify the signature.

Note: When this value is present, the control will automatically use this value to perform signature verification.

The SignerCert property may be set from within this event. In this manner, the decision of which signer certificate to load may be delayed until the parameters of this event are inspected and the correct certificate can be located and loaded.

SSLServerAuthentication Event (AS4Client Control)

Fired after the server presents its certificate to the client.

Syntax

Sub as4clientcontrol_SSLServerAuthentication(CertEncoded As String, CertSubject As String, CertIssuer As String, Status As String, Accept As Boolean)

Remarks

During this event, the client can decide whether or not to continue with the connection process. 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 or not to continue.

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 (AS4Client Control)

Fired when secure connection progress messages are available.

Syntax

Sub as4clientcontrol_SSLStatus(Message As String)

Remarks

The event is fired for informational and logging purposes only. This event tracks the progress of the connection.

StartTransfer Event (AS4Client Control)

This event is fired when a document starts transferring (after the headers).

Syntax

Sub as4clientcontrol_StartTransfer(Direction As Integer)

Remarks

The StartTransfer event is fired first when the client starts sending data to the server (in a POST or PUT request) and then when the document text starts transferring from the server to the local host.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

TokenAuthentication Event (AS4Client Control)

Fired when the server makes use of UsernameToken authentication.

Syntax

Sub as4clientcontrol_TokenAuthentication(User As String, Password As String, PasswordType As String, Accept As Boolean)

Remarks

This event fires when a server sends a response that includes UsernameToken authentication. This is typically only used by servers when sending a pull response.

User identifies the user.

Password should be set from within the event if PasswordType is 0 (digest). This parameter can be read when PasswordType is 1 (text).

PasswordType specifies the type of password. Possible values are:

• 0 (Digest)
• 1 (Text)

Accept may be set to manually accept the request.

When PasswordType is 0 (Digest) set the Password parameter to the plaintext password. Do not set Accept The control will hash the provided password value and compare it to the value in the request. If it matched the control will accept the request. If it does not match the control will populate Errors with an error indicating authentication has failed.

When PasswordType is 1 (Text) the Password parameter will hold the exact value received in the request. Inspect Password and determine whether to accept the request. To accept the request set Accept to True.

After this event fires if authentication failed Errors will contain an appropriate error. Send the errors back to the server by calling SendResponse.

Transfer Event (AS4Client Control)

This event is fired while a document transfers (delivers document).

Syntax

Sub as4clientcontrol_Transfer(Direction As Integer, BytesTransferred As Long64, PercentDone As Integer, Text As String)

Remarks

The Text parameter contains the portion of the document text being received. It is empty if data are being posted to the server.

The BytesTransferred parameter contains the number of bytes transferred in this Direction since the beginning of the document text (excluding HTTP response headers).

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

The PercentDone parameter shows the progress of the transfer in the corresponding direction. If PercentDone can not be calculated the value will be -1.

Note: Events are not re-entrant. Performing time-consuming operations within this event will prevent it from firing again in a timely manner and may affect overall performance.
