OFTPClient Class

Properties   Methods   Events   Config Settings   Errors  

The OFTPClient class implements the Odette File Transfer Protocol.

Syntax

class ipworksedi.OFTPClient

Remarks

The OFTPClient component may be used to send and receive OFTP files to and from an OFTP server.

Receiving Files

The OFTPClient receive_files function requires certain server properties be set. You must set the remote_host property to the remote location of the desired OFTP server. You may also set a remote_port if the server is not set to the default protocol port. For client authorization, you must set the client_ssid_code, client_sfid_code, and client_password properties. And, for server authentication, you must set the server_ssid_code, server_sfid_code, and server_password properties.

The class will connect to the OFTP server and download all files in the server's outgoing queue, and write these files to the directory specified by download_directory. The class creates a default location on the local machine based on the values of the download_directory and the Virtual Filename as received from the server. If a different location is preferred, you may set the LocalFile parameter of the on_start_transfer event.

Sending Files

The OFTPClient send_file function requires the same server and authentication properties to be set as the receive_files function.

The class will connect to the OFTP server and upload the file contained by the LocalFile parameter. It uses the name specified by VirtualFileName when sending to the server. If this is not specified, the filename of the local file is parsed and used as the virtual filename.

def set_cert_encoded(value: bytes) -> None: ...

cert_encoded = property(get_cert_encoded, set_cert_encoded)

Default Value

""

Remarks

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

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

cert_store Property

This is the name of the certificate store for the client certificate.

Syntax

def get_cert_store() -> bytes: ...
def set_cert_store(value: bytes) -> None: ...

cert_store = property(get_cert_store, set_cert_store)

Default Value

"MY"

Remarks

This is 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 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., 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

""

Remarks

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

cert_store_type Property

This is the type of certificate store for this certificate.

Syntax

def get_cert_store_type() -> int: ...
def set_cert_store_type(value: int) -> None: ...

cert_store_type = property(get_cert_store_type, set_cert_store_type)

Default Value

0

Remarks

This is the type of certificate store for this certificate.

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

This is 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

This is 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.

client_password Property

The client's password.

Syntax

def get_client_password() -> str: ...
def set_client_password(value: str) -> None: ...

client_password = property(get_client_password, set_client_password)

timeout Property

A 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 return immediately, potentially failing with a WOULDBLOCK error if data cannot be sent immediately.

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

The class will use 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.

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.

trusted_cert_count Property

The number of records in the TrustedCert arrays.

Syntax

def get_trusted_cert_count() -> int: ...

def get_trusted_cert_encoded(trusted_cert_index: int) -> bytes: ...
def set_trusted_cert_encoded(trusted_cert_index: int, value: bytes) -> None: ...

Default Value

""

Remarks

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

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

The trusted_cert_index parameter specifies the index of the item in the array. The size of the array is controlled by the trusted_cert_count property.

trusted_cert_store Property

This is the name of the certificate store for the client certificate.

Syntax

def get_trusted_cert_store(trusted_cert_index: int) -> bytes: ...
def set_trusted_cert_store(trusted_cert_index: int, value: bytes) -> None: ...

Default Value

"MY"

Remarks

This is the name of the certificate store for the client certificate.

The trusted_cert_store_type property denotes the type of the certificate store specified by trusted_cert_store. If the store is password protected, specify the password in trusted_cert_store_password.

trusted_cert_store is used in conjunction with the trusted_cert_subject property to specify client certificates. If trusted_cert_store has a value, and trusted_cert_subject or trusted_cert_encoded is set, a search for a certificate is initiated. Please see the trusted_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 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., PKCS#12 certificate store).

The trusted_cert_index parameter specifies the index of the item in the array. The size of the array is controlled by the trusted_cert_count property.

trusted_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_trusted_cert_store_password(trusted_cert_index: int) -> str: ...
def set_trusted_cert_store_password(trusted_cert_index: int, value: str) -> None: ...

Default Value

""

Remarks

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

The trusted_cert_index parameter specifies the index of the item in the array. The size of the array is controlled by the trusted_cert_count property.

trusted_cert_store_type Property

This is the type of certificate store for this certificate.

Syntax

def get_trusted_cert_store_type(trusted_cert_index: int) -> int: ...
def set_trusted_cert_store_type(trusted_cert_index: int, value: int) -> None: ...

Default Value

0

Remarks

This is the type of certificate store for this certificate.

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:

The trusted_cert_index parameter specifies the index of the item in the array. The size of the array is controlled by the trusted_cert_count property.

trusted_cert_subject Property

This is the subject of the certificate used for client authentication.

Syntax

def get_trusted_cert_subject(trusted_cert_index: int) -> str: ...
def set_trusted_cert_subject(trusted_cert_index: int, value: str) -> None: ...

Default Value

""

Remarks

This is 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.

The trusted_cert_index parameter specifies the index of the item in the array. The size of the array is controlled by the trusted_cert_count property.

use_ssl Property

Use SSL to access the RemoteHost .

Syntax

def get_use_ssl() -> bool: ...
def set_use_ssl(value: bool) -> None: ...

use_ssl = property(get_use_ssl, set_use_ssl)

Default Value

FALSE

Remarks

Use this property to determine whether the class uses SSL to connect with the remote_host.

This property is only valid when using version 2.0 of the protocol.

Note: Setting this property to True will set remote_port to 6619.

version Property

Which version of the OFTP protocol the class is using.

Syntax

def get_version() -> int: ...
def set_version(value: int) -> None: ...

version = property(get_version, set_version)

Default Value

3

Remarks

This property specifies which version of the OFTP protocol to use. Possible values are:

The default value is oftpVer20 (Version 2.0).

Note: Version 2.0 (oftpVer20) of the protocol must be used when using security functions. The following properties are only applicable when using Version 2.0:

• use_ssl
• secure_authentication
• virtual_file_security_level
• compress

virtual_file_date Property

The date/time stamp for the virtual file.

Syntax

def get_virtual_file_date() -> str: ...
def set_virtual_file_date(value: str) -> None: ...

virtual_file_date = property(get_virtual_file_date, set_virtual_file_date)

Default Value

""

Remarks

Set this to the date/time stamp for the virtual file before sending. If this is not set when sending a file, the current date/time will be used. This property will accept various date formats, but will return the following format only: "MM/dd/yyyy HH:mm:ss".

Supported date formats:

• ddd, d MMM yy HH:mm:ss zzz
• ddd, d MMM yyyy HH:mm:ss zzz

virtual_file_format Property

The structure of the outgoing file.

Syntax

def get_virtual_file_format() -> int: ...
def set_virtual_file_format(value: int) -> None: ...

virtual_file_format = property(get_virtual_file_format, set_virtual_file_format)

Default Value

0

Remarks

The following values are valid file formats for outgoing virtual files:

Note: When either virtual_file_security_level has been set to a value other than slNone or compress has been set to true, all files become ffUnstructured except ffVariable files.

virtual_file_security_level Property

The level of security for the file.

Syntax

def get_virtual_file_security_level() -> int: ...
def set_virtual_file_security_level(value: int) -> None: ...

virtual_file_security_level = property(get_virtual_file_security_level, set_virtual_file_security_level)

Default Value

0

Remarks

When sending files, set this value to the level of security for the next virtual file to send. After receiving a file, this will be set to the level of security of the last file received.

When encrypting a file, recipient_cert must be set, and when signing a file, the certificate must be set.

The file will be processed to a temporary file before being sent.

This is only valid for version 2.0 of the protocol.

change_direction Method

Sends a Change Direction (CD) command.

Syntax

def change_direction() -> None: ...

Remarks

This method sends a Change Direction (CD) command to the remote host when called. In normal operation this should not be used. This should only be used if a condition arises where you must manually change the speaker when communicating with the remote host.

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.

connect Method

This method connects to the FTP server without logging in.

Syntax

def connect() -> None: ...

Remarks

This method establishes a connection with the remote_host but does not log in. In most cases, it is recommended to use the logon method, which will both establish a connection and log in to the server.

This method may be useful in cases in which it is desirable to separate the connection and logon operations, for instance, confirming that a host is available by first creating the connection.

disconnect Method

This method disconnects from the server without first logging off.

Syntax

def disconnect() -> None: ...

Remarks

This method immediately disconnects from the server without first logging off.

In most cases, the logoff method should be used to log off and disconnect from the server. Call the disconnect method in cases in which it is desirable to immediately disconnect without first logging off.

do_events 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.

exchange_certificate Method

Exchange a certificate with the remote host.

Syntax

def exchange_certificate(certificate_store: str, certificate_exchange_type: int) -> None: ...

Remarks

If the remote host supports the certificate exchange feature of OFTP 2.0 this method may be used to send and/or request certificates.

The CertificateStore parameter specifies the location of the certificate to be exchanged. In most cases this will be the path to a .cer file on disk. If the certificate is in another format or is installed to the Windows certificate store please see ExchangeCertStoreType and ExchangeCertSubject for more information.

The CertificateExchangeType parameter determines the type of request. Possible values are:

When the remote host sends a certificate to the class the received certificate will be provided through the on_certificate_received event.

import_trusted_certs Method

Imports a list of trusted CA certificates.

Syntax

def import_trusted_certs() -> None: ...

Remarks

When import_trusted_certs is called the class will import the CA certificates from the source specified by TrustedCertsData into the trusted_certs collection.

The class will then validate the trust of certificates when they are loaded.

If trusted CA certificates are not imported no validation will occur (default).

See also FailOnUntrustedCert.

interrupt Method

This method interrupts the current action.

Syntax

def interrupt() -> None: ...

Remarks

This method interrupts the current action. If you use send_file to upload a file, the class will run synchronously until the upload is completed. This method will allow you to stop the file from uploading without disconnecting from the host.

logoff Method

Logoff from the OFTP server.

Syntax

def logoff() -> None: ...

Remarks

Logoff from the OFTP server. If that fails, the connection is terminated by the local host.

logon Method

Logon to the OFTP RemoteHost using the current client credentials.

Syntax

def logon() -> None: ...

Remarks

Logon to the OFTP server using the current client_ssid_code, client_sfid_code, and client_password. The component will also check the corresponding server credentials, server_ssid_code, server_sfid_code, and server_password.

receive_files Method

Receive any files queued to be sent from the server.

Syntax

def receive_files() -> None: ...

Remarks

This method connects to the server, and receives any files the server has in its outgoing queue to this particular partner. The files are downloaded to the directory specified by the download_directory property.

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_end_response Method

Sends an EERP/NERP asynchronously.

Syntax

def send_end_response(virtual_file_name: str, virtual_file_date: str, destination: str, originator: str, creator: str, reason_code: int, reason_text: str, file_hash: str, signature: str) -> None: ...

Remarks

This method sends an EERP/NERP. By default the class will automatically respond with an EERP/NERP when receiving a file. To respond asynchronously instead this method may be used.

To respond asynchronously first set the SendEndResponse parameter of the on_end_transfer event to False. This instructs the class to not send a response automatically. Within the on_end_transfer event you must also save the values that are required parameters for this method. This includes FileHash, VirtualFileDate, and VirtualFileName. Note: VirtualFileDateFormat must be set to a format that includes the necessary level of accuracy.

Destination should be set to the SFID of the remote host.

Originator should be set to the SFID of the local system. In the case that the class is being used as part of a gateway process to forward traffic to another OFTP host this may be set to the SFID of that host instead.

Creator should be set to the SFID of the local system.

Signature is only applicable if the application is acting as a routing application. In all other cases this should be set to empty string. In the case where the application is acting as a routing application the end response is being forwarded to another entity for processing. The Signature should be set to the value received in the on_end_response event (if populated).

ReasonCode and ReasonText are used to specify error information. If ReasonCode is set to 0 the class will send an EERP. If ReasonCode is set to any non-zero value the class will send a NERP. Common values are:

send_file Method

Send the specified file to the server.

Syntax

def send_file(local_file: str, virtual_file_name: str) -> None: ...

Remarks

This method connects to the server, and uploads the specified file to the server. The LocalFile parameter contains the path and name of the file to send to the server. The VirtualFileName parameter contains the virtual file name of the file being sent. If this parameter is left as an empty string, the component will use the filename contained in the LocalFile parameter by default.

Note: When set_upload_stream has been called with a valid input stream, the data will be uploaded from there instead of the LocalFile.

validate_cert Method

Validates the certificate with private key.

Syntax

def validate_cert() -> bool: ...

Remarks

This method optionally validates the certificate specified by certificate. It is not required to validate the certificate from a technical perspective, but may be desired to ensure the recipient's certificate is valid and issued by a trusted authority.

Before calling this method call import_trusted_certs to load the trusted certification information.

When this method is called the class:

• Validates the certificate has not expired
• Validates the certificate was issued by a CA in the trusted_certs collection. If the certificate is self-signed this step is skipped.
• Validates the certificate has not been revoked. Note that the revocation check will only make use of the CRL distribution point identified in the certificate's extension. If the certificate does not contain a CRL distribution point extension this step is skipped.

validate_recipient_cert Method

Validates the recipient certificate.

Syntax

def validate_recipient_cert() -> bool: ...

Remarks

This method optionally validates the certificate specified by recipient_cert. It is not required to validate the certificate from a technical perspective, but may be desired to ensure the recipient's certificate is valid and issued by a trusted authority.

Before calling this method call import_trusted_certs to load the trusted certification information.

When this method is called the class:

• Validates the certificate has not expired
• Validates the certificate was issued by a CA in the trusted_certs collection. If the certificate is self-signed this step is skipped.
• Validates the certificate has not been revoked. Note that the revocation check will only make use of the CRL distribution point identified in the certificate's extension. If the certificate does not contain a CRL distribution point extension this step is skipped.

on_accept_file Event

Fired when the client receives a file.

Syntax

class OFTPClientAcceptFileEventParams(object):
  @property
  def virtual_file_name() -> str: ...

  @property

def on_accept_file() -> Callable[[OFTPClientAcceptFileEventParams], None]: ...
@on_accept_file.setter
def on_accept_file(event_hook: Callable[[OFTPClientAcceptFileEventParams], None]) -> None: ...

Remarks

This event controls the behavior when the client receives a file.

VirtualFileName holds the name of the file being received.

VirtualFileDate holds the date associated with the file in the format specified by VirtualFileDateFormat. The default value is "MM/dd/yyyy HH:mm:ss".

Destination identifies the receiver (SFID) code in the send file request. If the file was intended for this server this will match the value in server_sfid_code

Originator identifies the sender (SFID) code in the send file request.

Accept is true by default, and must be set to False in order to reject the file.

Filename will be populated with the full path and filename that will be written. It may be changed within this event to specify a new location. The Filename is determined by combining the path specified in oftp_connection_download_directory and the name received from the client.

Overwrite is false by default, but may be set to true to overwrite existing files on disk.

ErrorCode controls the error returned to the client when Accept is set to False. If this is not set the class will use a value of 99 to indicate a general error.

ErrorDescription may also be set to include an error message. If this is not set the class will automatically include an error message based on the ErrorCode specified. Common error codes and their corresponding error messages are listed below.

on_certificate_received Event

Fired when a certificate is received from the remote host.

Syntax

class OFTPClientCertificateReceivedEventParams(object):
  @property
  def certificate_file_name() -> str: ...

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

# In class OFTPClient:
@property
def on_certificate_received() -> Callable[[OFTPClientCertificateReceivedEventParams], None]: ...
@on_certificate_received.setter
def on_certificate_received(event_hook: Callable[[OFTPClientCertificateReceivedEventParams], None]) -> None: ...

Remarks

This event provides information about the certificate file that was sent by the remote host.

When the remote host sends a certificate using the Certificate Exchange feature of OFTP 2.0, this event provides information about it. The certificate file will be written to the download_directory. After the file is written to download_directory this event will fire.

The CertificateFilemame parameter holds the filename of the received certificate.

The CertificateExchangeType parameter identifies the type of request associated with the certificate. Possible values are:

on_end_response Event

Fired every time an end response is received from the server.

Syntax

class OFTPClientEndResponseEventParams(object):
  @property
  def virtual_file_name() -> str: ...

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

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

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

# In class OFTPClient:
@property
def on_end_response() -> Callable[[OFTPClientEndResponseEventParams], None]: ...
@on_end_response.setter
def on_end_response(event_hook: Callable[[OFTPClientEndResponseEventParams], None]) -> None: ...

Remarks

This event contains information received from an either an End-To-End Response or a Negative End Response received from the server.

An End-To-End Response will not contain values for the ReasonCode, ReasonText, or Creator parameters.

VirtualFileName specifies the name of the file.

VirtualFileDate holds the VirtualFileDate value in the format specified by VirtualFileDateFormat. The default value is "MM/dd/yyyy HH:mm:ss".

Destination is the SFID of the destination system (this class).

Originator identifies the system that originated the end response. This is typically the same as Creator and holds the remote system's SFID.

Creator is the SFID of the remote system.

Direction specifies whether the end response is being received or sent. Possible values are:

By default the class will only fire this event for received end responses. To configure the class to fire the event for both send and received end responses set FireEndResponseOnSend to True.

FileHash is populated if the OFTP Version is 2.0 and a signed receipt was originally requested. FileHash may also be specified with the expected value in the case where an asynchronous EndResponse is received. The expected value may be obtained from the on_end_transfer event when initially sending the file.

Signature is only applicable when the OFTP version is 2.0 and the application is acting as a routing application where the end response will be forwarded on to another entity. In this case Signature will be populated if the end response is signed. This should be stored and supplied when forwarding the response with the send_end_response method.

ReasonCode and ReasonText identify the error if a Negative End Response (NERP) was received. A value of 0 indicates there was no an error and the response is an End-To-End Response (EERP). Common values are:

on_end_transfer Event

Fired when a file finishes transferring.

Syntax

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

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

def on_end_transfer() -> Callable[[OFTPClientEndTransferEventParams], None]: ...
@on_end_transfer.setter
def on_end_transfer(event_hook: Callable[[OFTPClientEndTransferEventParams], None]) -> None: ...

Remarks

The on_end_transfer event is fired when a file is sent or received by the class.

The FileSize parameter gives the size of the file that was sent or received.

The Direction parameter shows whether the client or the server is sending the data.

VirtualFileName holds the filename.

VirtualFileDate holds the date associated with the file in the format specified by VirtualFileDateFormat. The default value is "MM/dd/yyyy HH:mm:ss".

Originator identifies the sender (SFID) code in the send file request.

Destination identifies the receiver (SFID) code in the send file request.

SendEndResponse indicates whether the EERP/NERP for this request should be sent synchronously or asynchronously. When this parameter is True (default) the class will automatically respond with an EERP/NERP synchronously. To respond asynchronously set this parameter to False. You may then use the send_end_response method to send the response at a later time. See send_end_response for more details. Note: VirtualFileDateFormat must be set to a format that includes the necessary level of accuracy.

FileHash holds the hash of the file being transmitted. This is only applicable when the OFTP version is 2.0 and the sender requested a signed receipt. When receiving files this value should be saved if you wish to respond asynchronously using send_end_response. See send_end_response for more details.

LocalFile holds the full path to the file that will be written.

ReasonCode and ReasonText identify the error if a Negative End Response (NERP) was received. A value of 0 indicates there was no an error and the response is an End-To-End Response (EERP). Common values are:

on_error Event

Fired when information is available about errors during data delivery.

Syntax

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

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

# In class OFTPClient:
@property
def on_error() -> Callable[[OFTPClientErrorEventParams], None]: ...
@on_error.setter
def on_error(event_hook: Callable[[OFTPClientErrorEventParams], 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_log Event

Fires once for each log message.

Syntax

class OFTPClientLogEventParams(object):
  @property
  def log_level() -> int: ...

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

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

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

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:

Message is the log entry.

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

• "Info"
• "OFTP"

on_pi_trail Event

Fired when any protocol level communication occurs.

Syntax

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

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

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

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

# In class OFTPClient:
@property
def on_pi_trail() -> Callable[[OFTPClientPITrailEventParams], None]: ...
@on_pi_trail.setter
def on_pi_trail(event_hook: Callable[[OFTPClientPITrailEventParams], None]) -> None: ...

Remarks

This event provides information about the protocol level communication between the client and server.

The Direction parameter specifies who sent the command.

The CommandId and CommandDescription parameters specify which command was sent. The table below shows possible values.

The Data parameter contains the raw OFTP packet.

on_ssl_server_authentication Event

Fired after the server presents its certificate to the client.

Syntax

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

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

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

@on_ssl_server_authentication.setter
def on_ssl_server_authentication(event_hook: Callable[[OFTPClientSSLServerAuthenticationEventParams], 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 OFTPClientSSLStatusEventParams(object):
  @property
  def message() -> str: ...

# In class OFTPClient:
