AS4Client Class

Properties   Methods   Events   Config Settings   Errors  

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

Syntax

class ipworksedi.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

send_files sends the files specified by edi_data to url.

Before calling this method set agreement_ref to the agreement identifier used by both parties. Set as4_from and as4_to. Set edi_data specifies the file(s) to be sent. To encrypt the data set recipient_certs. To sign the data set signing_cert. The signer_cert 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 receipt_reply_mode to rrmSync. The following properties are applicable when calling this method with an agreement specifying a synchronous receipt (a receipt provided in the response):

• agreement_ref
• as4_from
• as4_to
• edi_data
• url
• recipient_certs (required to encrypt)
• signer_cert (required to verify signed receipts)
• signing_cert (required to sign files)
• conversation_id (optional)
• encryption_algorithm (optional)
• log_directory (optional)
• message_id (optional)
• message_properties (optional)
• profile (optional)
• receipt_reply_mode
• service (optional)
• service_type (optional)
• signature_algorithm (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 class also supports asynchronous receipts. In this configuration a file is sent from the class 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 class 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 async_receipt_info_dir before calling send_files. The class will automatically store the required information.

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

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

• agreement_ref
• as4_from
• as4_to
• async_receipt_info_dir
• edi_data
• url
• recipient_certs (required to encrypt)
• signer_cert (required to verify signed receipts)
• signing_cert (required to sign files)
• conversation_id (optional)
• encryption_algorithm (optional)
• log_directory (optional)
• message_id (optional)
• message_properties (optional)
• original_soap_message (optional)
• original_soap_message_id (optional)
• profile (optional)
• receipt_reply_mode
• service (optional)
• service_type (optional)
• signature_algorithm (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

receive_files 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 incoming_directory is set before calling this method the files will be written to the specified folder, otherwise inspect edi_data to obtain the received file data. The following properties are applicable when calling this method:

• signing_cert (required to sign the request)
• certificate (required for decryption)
• signer_cert (required for signature verification)
• url
• incoming_directory (optional)
• log_directory
• mpc
• token_user
• token_password
• token_password_type

• as4_from
• as4_to
• agreement_ref
• conversation_id
• service
• service_action
• service_type
• message_id
• receipt

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

send_receipt 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();

Default Value

"MY"

Remarks

The name of the certificate store for the client certificate.

The cert_store_type property denotes the type of the certificate store specified by cert_store. If the store is password-protected, specify the password in cert_store_password.

cert_store is used in conjunction with the cert_subject property to specify client certificates. If cert_store has a value, and cert_subject or cert_encoded is set, a search for a certificate is initiated. Please see the cert_subject property for details.

Designations of certificate stores are platform dependent.

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

When the certificate store type is cstPFXFile, this property must be set to the name of the file. When the type is cstPFXBlob, the property must be set to the binary contents of a PFX file (i.e., PKCS#12 certificate store).

cert_store_password Property

If the type of certificate store requires a password, this property is used to specify the password needed to open the certificate store.

Syntax

def get_cert_store_password() -> str: ...
def set_cert_store_password(value: str) -> None: ...

cert_store_password = property(get_cert_store_password, set_cert_store_password)

Default Value

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:

cert_subject Property

The subject of the certificate used for client authentication.

Syntax

def get_cert_subject() -> str: ...
def set_cert_subject(value: str) -> None: ...

cert_subject = property(get_cert_subject, set_cert_subject)

Default Value

""

Remarks

The subject of the certificate used for client authentication.

This property must be set after all other certificate properties are set. When this property is set, a search is performed in the current certificate store to locate a certificate with a matching subject.

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 as follows:

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

Default Value

0

Remarks

This setting specifies the compression format to be applied to the parts specified by edi_data. When profile is set to Standard the default value is 0 (ebcfNone). When profile is set to ENTSOG or eDelivery the default value is 1 (ebcfGZIP).

Possible values are:

• 0 (ebcfNone - default for Standard)
• 1 (ebcfGZIP - default for ENTSOG and eDelivery)

Note: When profile is set to Standard the first edi_data part will be included in the SOAP body if the ediedi_type is "text/xml" or "application/xml". In that case since the data is included in the SOAP body it will not be compressed. When profile is set to ENTSOG all edi_data parts are compressed.

conversation_id Property

The Conversation Id of the message.

Syntax

def get_conversation_id() -> str: ...
def set_conversation_id(value: str) -> None: ...

Default Value

"rfc1767.edi"

Remarks

edi_name is the final name to be associated with the contents of either the edi_data or edi_file_name properties. This corresponds to the filename attribute of the Content-Disposition header for the EDI payload.

When constructing EDI data to be sent, edi_name will be set to the same value as edi_file_name, but can be overridden after setting edi_file_name to indicate that another name should be used in the outbound request's Content-Disposition MIME header.

When receiving EDI data, edi_name will be read out of the "filename" attribute of the inbound request's Content-Disposition MIME header.

The edi_data_index parameter specifies the index of the item in the array. The size of the array is controlled by the edi_data_count property.

edi_property_count Property

The number of properties for this file.

def set_edi_property_count(edi_data_index: int, value: int) -> None: ...

Default Value

0

Remarks

The number of properties for this file.

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

Sending

When sending files to add properties set edi_property_count to specify the number of properties. Then set edi_property_index to select the property. Set edi_property_name and edi_property_value to define the values for the property at edi_property_index.

The certificate (PEM/Base64 encoded). This property is used to assign a specific certificate. The recipient_cert_store and recipient_cert_subject properties also may be used to specify a certificate.

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

The recipient_cert_index parameter specifies the index of the item in the array. The size of the array is controlled by the recipient_cert_count property.

ref_to_message_id Property

Specifies the RefToMessageId in the message.

Syntax

Default Value

""

Remarks

This property specifies the RefToMessageId value in the message being sent.

This property is only applicable when profile is set to ebpfEDelivery. The eDelivery profile supports the Two-Way/Push-and-Push MEP (Message Exchange Pattern), where sending a file can be in reference to a previously received file. In this case ref_to_message_id specifies the Id of the previously received message to which this send is in reference.

When sending with AS4Client this should only be set when using the eDelivery profile and need to explicitly specify the RefToMessageId value as per the Two-Way/Push-And-Push MEP.

When receiving with AS4Server this may be read after receiving a message.

If the key is found, ssl_server_cert_subject is updated to reflect the full subject of the selected certificate; otherwise, ssl_server_cert_subject is set to an empty string.

This property is read-only.

timeout Property

The timeout for the class.

Syntax

def get_timeout() -> int: ...
def set_timeout(value: int) -> None: ...

timeout = property(get_timeout, set_timeout)

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 class will wait for the operation to complete before returning control.

The class will use do_events 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.

Note: By default, all timeouts are inactivity timeouts, that is, 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.

token_password Property

The password used in UsernameToken authentication.

Syntax

def get_token_password() -> str: ...
def set_token_password(value: str) -> None: ...

token_password = property(get_token_password, set_token_password)

Default Value

""

Remarks

This property specifies the password used in UsernameToken authentication.

UsernameToken Authentication Notes

If token_user and token_password are specified the class will include UsernameToken authentication when receive_files is called. This functionality is only applicable when calling receive_files.

token_password should normally be set to the plaintext password that both the client and server know. The class will automatically use SHA-1 to create a hash of the password when token_password_type 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 token_password_type is set to tptText the class will transmit value provided in token_password 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.

token_password_type Property

The password type used in UsernameToken authentication.

Syntax

def get_token_password_type() -> int: ...
def set_token_password_type(value: int) -> None: ...

Remarks

The type of password to send in the request. Possible values are:

UsernameToken Authentication Notes

If token_user and token_password are specified the class will include UsernameToken authentication when receive_files is called. This functionality is only applicable when calling receive_files.

token_password should normally be set to the plaintext password that both the client and server know. The class will automatically use SHA-1 to create a hash of the password when token_password_type 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 token_password_type is set to tptText the class will transmit value provided in token_password 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.

token_user Property

The username used in UsernameToken authentication.

Syntax

def get_token_user() -> str: ...
def set_token_user(value: str) -> None: ...

token_user = property(get_token_user, set_token_user)

Default Value

""

Remarks

This property specifies the username to be sent for UsernameToken authentication.

UsernameToken Authentication Notes

If token_user and token_password are specified the class will include UsernameToken authentication when receive_files is called. This functionality is only applicable when calling receive_files.

token_password should normally be set to the plaintext password that both the client and server know. The class will automatically use SHA-1 to create a hash of the password when token_password_type is set to tptDigest (default).

url Property

The URL to which the request is made.

Syntax

def get_url() -> str: ...
def set_url(value: str) -> None: ...

url = property(get_url, set_url)

Default Value

""

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".

config Method

Sets or retrieves a configuration setting.

Syntax

def config(configuration_string: str) -> str: ...

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.

do_events Method

This method processes events from the internal message queue.

Syntax

def do_events() -> None: ...

Remarks

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

interrupt Method

This method interrupts the current method.

Syntax

def interrupt() -> None: ...

Remarks

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

receive_files Method

Connects to a server to receive files.

Syntax

def receive_files() -> None: ...

Remarks

receive_files 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 incoming_directory is set before calling this method the files will be written to the specified folder, otherwise inspect edi_data to obtain the received file data. The following properties are applicable when calling this method:

• signing_cert (required to sign the request)
• certificate (required for decryption)
• signer_cert (required for signature verification)
• url
• incoming_directory (optional)
• log_directory
• mpc
• token_user
• token_password
• token_password_type

• as4_from
• as4_to
• agreement_ref
• conversation_id
• service
• service_action
• service_type
• message_id
• receipt

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

Resets the state of the control.

Syntax

def reset() -> None: ...

Remarks

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

send_files Method

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

Syntax

def send_files() -> None: ...

Remarks

send_files sends the files specified by edi_data to url.

Before calling this method set agreement_ref to the agreement identifier used by both parties. Set as4_from and as4_to. Set edi_data specifies the file(s) to be sent. To encrypt the data set recipient_certs. To sign the data set signing_cert. The signer_cert 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 receipt_reply_mode to rrmSync. The following properties are applicable when calling this method with an agreement specifying a synchronous receipt (a receipt provided in the response):

• agreement_ref
• as4_from
• as4_to
• edi_data
• url
• recipient_certs (required to encrypt)
• signer_cert (required to verify signed receipts)
• signing_cert (required to sign files)
• conversation_id (optional)
• encryption_algorithm (optional)
• log_directory (optional)
• message_id (optional)
• message_properties (optional)
• profile (optional)
• receipt_reply_mode
• service (optional)
• service_type (optional)
• signature_algorithm (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 class also supports asynchronous receipts. In this configuration a file is sent from the class 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 class 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 async_receipt_info_dir before calling send_files. The class will automatically store the required information.

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

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

• agreement_ref
• as4_from
• as4_to
• async_receipt_info_dir
• edi_data
• url
• recipient_certs (required to encrypt)
• signer_cert (required to verify signed receipts)
• signing_cert (required to sign files)
• conversation_id (optional)
• encryption_algorithm (optional)
• log_directory (optional)
• message_id (optional)
• message_properties (optional)
• original_soap_message (optional)
• original_soap_message_id (optional)
• profile (optional)
• receipt_reply_mode
• service (optional)
• service_type (optional)
• signature_algorithm (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 }

send_receipt Method

Sends an asynchronous receipt.

Syntax

def send_receipt() -> None: ...

Remarks

send_receipt 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();

Please refer to the Error Codes section for more information.

on_end_transfer Event

Fired when a document finishes transferring.

Syntax

class AS4ClientEndTransferEventParams(object):
  @property
  def direction() -> int: ...

# In class AS4Client:
@property
def on_end_transfer() -> Callable[[AS4ClientEndTransferEventParams], None]: ...
@on_end_transfer.setter
def on_end_transfer(event_hook: Callable[[AS4ClientEndTransferEventParams], None]) -> None: ...

Remarks

This 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.

on_error Event

Fired when information is available about errors during data delivery.

Syntax

class AS4ClientErrorEventParams(object):
  @property
  def error_code() -> int: ...

  @property
  def description() -> str: ...

# In class AS4Client:
@property
def on_error() -> Callable[[AS4ClientErrorEventParams], None]: ...
@on_error.setter
def on_error(event_hook: Callable[[AS4ClientErrorEventParams], None]) -> None: ...

Remarks

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

on_header Event

Fired every time a header line comes in.

Syntax

class AS4ClientHeaderEventParams(object):
  @property
  def field() -> str: ...

  @property
  def value() -> str: ...

# In class AS4Client:
@property
def on_header() -> Callable[[AS4ClientHeaderEventParams], None]: ...
@on_header.setter
def on_header(event_hook: Callable[[AS4ClientHeaderEventParams], None]) -> None: ...

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).

on_log Event

Fired with log information while processing a message.

Syntax

class AS4ClientLogEventParams(object):
  @property
  def log_type() -> str: ...

  @property
  def log_message() -> str: ...

# In class AS4Client:
@property
def on_log() -> Callable[[AS4ClientLogEventParams], None]: ...
@on_log.setter
def on_log(event_hook: Callable[[AS4ClientLogEventParams], None]) -> None: ...

Remarks

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

Log messages available through this event correspond to log files written to log_directory. This event provides a way to obtain log messages without relying on files on disk. This event fires regardless of the value of log_directory (i.e. when log_directory 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:

on_recipient_info Event

Fired for each recipient certificate of the encrypted message.

Syntax

class AS4ClientRecipientInfoEventParams(object):
  @property
  def issuer() -> str: ...

  @property
  def serial_number() -> str: ...

  @property
  def subject_key_identifier() -> str: ...

  @property
  def encryption_algorithm() -> str: ...

# In class AS4Client:
@property
def on_recipient_info() -> Callable[[AS4ClientRecipientInfoEventParams], None]: ...
@on_recipient_info.setter
def on_recipient_info(event_hook: Callable[[AS4ClientRecipientInfoEventParams], None]) -> None: ...

Remarks

When parse_request 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"

on_set_cookie Event

Fired for every cookie set by the server.

Syntax

class AS4ClientSetCookieEventParams(object):
  @property
  def name() -> str: ...

  @property
  def value() -> str: ...

  @property
  def expires() -> str: ...

  @property
  def domain() -> str: ...

  @property
  def path() -> str: ...

  @property
  def secure() -> bool: ...

# In class AS4Client:
@property
def on_set_cookie() -> Callable[[AS4ClientSetCookieEventParams], None]: ...
@on_set_cookie.setter
def on_set_cookie(event_hook: Callable[[AS4ClientSetCookieEventParams], None]) -> None: ...

Remarks

This 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 (url_server) 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 (url_path) 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.

on_signer_cert_info Event

This event is fired during verification of the signed message.

Syntax

class AS4ClientSignerCertInfoEventParams(object):
  @property
  def issuer() -> str: ...

  @property
  def serial_number() -> str: ...

  @property
  def subject_key_identifier() -> str: ...

  @property
  def cert_encoded() -> bytes: ...

# In class AS4Client:
@property
def on_signer_cert_info() -> Callable[[AS4ClientSignerCertInfoEventParams], None]: ...
@on_signer_cert_info.setter
def on_signer_cert_info(event_hook: Callable[[AS4ClientSignerCertInfoEventParams], None]) -> None: ...

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 signer_cert 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 class will automatically use this value to perform signature verification.

The signer_cert 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.

on_ssl_server_authentication Event

Fired after the server presents its certificate to the client.

Syntax

class AS4ClientSSLServerAuthenticationEventParams(object):
  @property
  def cert_encoded() -> bytes: ...

  @property
  def cert_subject() -> str: ...

  @property
  def cert_issuer() -> str: ...

  @property
  def status() -> str: ...

  @property
  def accept() -> bool: ...
  @accept.setter
  def accept(value) -> None: ...

# In class AS4Client:
@property
def on_ssl_server_authentication() -> Callable[[AS4ClientSSLServerAuthenticationEventParams], None]: ...
@on_ssl_server_authentication.setter
def on_ssl_server_authentication(event_hook: Callable[[AS4ClientSSLServerAuthenticationEventParams], None]) -> None: ...

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.

on_ssl_status Event

Fired when secure connection progress messages are available.

Syntax

class AS4ClientSSLStatusEventParams(object):
  @property
  def message() -> str: ...

# In class AS4Client:
@property
def on_ssl_status() -> Callable[[AS4ClientSSLStatusEventParams], None]: ...
@on_ssl_status.setter
def on_ssl_status(event_hook: Callable[[AS4ClientSSLStatusEventParams], None]) -> None: ...

Remarks

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

on_start_transfer Event

Fired when a document starts transferring (after the headers).

Syntax

class AS4ClientStartTransferEventParams(object):
  @property
  def direction() -> int: ...

# In class AS4Client:
@property
def on_start_transfer() -> Callable[[AS4ClientStartTransferEventParams], None]: ...
@on_start_transfer.setter
def on_start_transfer(event_hook: Callable[[AS4ClientStartTransferEventParams], None]) -> None: ...

Remarks

This 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.

on_token_authentication Event

Fired when the server makes use of UsernameToken authentication.

Syntax

class AS4ClientTokenAuthenticationEventParams(object):
  @property
  def user() -> str: ...

  @property
  def password() -> str: ...
  @password.setter
  def password(value) -> None: ...

  @property
  def password_type() -> str: ...

  @property
  def accept() -> bool: ...
  @accept.setter
  def accept(value) -> None: ...

# In class AS4Client:
@property
def on_token_authentication() -> Callable[[AS4ClientTokenAuthenticationEventParams], None]: ...
@on_token_authentication.setter
def on_token_authentication(event_hook: Callable[[AS4ClientTokenAuthenticationEventParams], None]) -> None: ...

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 class will hash the provided password value and compare it to the value in the request. If it matched the class will accept the request. If it does not match the class 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 send_response.

on_transfer Event

Fired while a document transfers (delivers document).

Syntax

class AS4ClientTransferEventParams(object):
  @property
  def direction() -> int: ...

  @property
  def bytes_transferred() -> int: ...

  @property
  def percent_done() -> int: ...

  @property
  def text() -> bytes: ...

# In class AS4Client:
@property
def on_transfer() -> Callable[[AS4ClientTransferEventParams], None]: ...
@on_transfer.setter
def on_transfer(event_hook: Callable[[AS4ClientTransferEventParams], None]) -> None: ...

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.
