Remarks

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

Receiving Files

The OFTPClient ReceiveFiles function requires certain server properties be set. You must set the RemoteHost property to the remote location of the desired OFTP server. You may also set a RemotePort if the server is not set to the default protocol port. For client authorization, you must set the ClientSSIDCode, ClientSFIDCode, and ClientPassword properties. And, for server authentication, you must set the ServerSSIDCode, ServerSFIDCode, and ServerPassword 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 DownloadDirectory. The class creates a default location on the local machine based on the values of the DownloadDirectory and the Virtual Filename as received from the server. If a different location is preferred, you may set the LocalFile parameter of the StartTransfer event.

Sending Files

The OFTPClient SendFile function requires the same server and authentication properties to be set as the ReceiveFiles 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.

ipworksedi_oftpclient_set($res, 125, $value );

Default Value

'MY'

Remarks

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

The SSLCertStoreType property denotes the type of the certificate store specified by SSLCertStore. If the store is password protected, specify the password in SSLCertStorePassword.

SSLCertStore is used in conjunction with the SSLCertSubject property to specify client certificates. If SSLCertStore has a value, and SSLCertSubject or SSLCertEncoded is set, a search for a certificate is initiated. Please see the SSLCertSubject 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).

Data Type

Binary String

SSLCertStorePassword Property (IPWorksEDI_OFTPClient Class)

String

SSLCertStoreType Property (IPWorksEDI_OFTPClient Class)

This is the type of certificate store for this certificate.

Object Oriented Interface

public function getSSLCertStoreType();


public function setSSLCertStoreType($value);

Procedural Interface

ipworksedi_oftpclient_get($res, 127 );


ipworksedi_oftpclient_set($res, 127, $value );

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:

Data Type

Integer

SSLCertSubject Property (IPWorksEDI_OFTPClient Class)

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

Object Oriented Interface

public function getSSLCertSubject();


public function setSSLCertSubject($value);

Procedural Interface

ipworksedi_oftpclient_get($res, 128 );


ipworksedi_oftpclient_set($res, 128, $value );

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.

Data Type

String

Timeout Property (IPWorksEDI_OFTPClient Class)

A timeout for the class.

Object Oriented Interface

public function getTimeout();


public function setTimeout($value);

Procedural Interface

ipworksedi_oftpclient_get($res, 136 );


ipworksedi_oftpclient_set($res, 136, $value );

Default Value

60

Remarks

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

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

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

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

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

The default value for the Timeout property is 60 seconds.

Exchange a certificate with the remote host.

Object Oriented Interface

public function doExchangeCertificate($certificatestore, $certificateexchangetype);

Procedural Interface

ipworksedi_oftpclient_do_exchangecertificate($res, $certificatestore, $certificateexchangetype);

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 CertificateReceived event.

ImportTrustedCerts Method (IPWorksEDI_OFTPClient Class)

Imports a list of trusted CA certificates.

Object Oriented Interface

public function doImportTrustedCerts();

Procedural Interface

ipworksedi_oftpclient_do_importtrustedcerts($res);

Remarks

When ImportTrustedCerts is called the class will import the CA certificates from the source specified by TrustedCertsData into the TrustedCerts 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 (IPWorksEDI_OFTPClient Class)

This method interrupts the current action.

Object Oriented Interface

public function doInterrupt();

Procedural Interface

ipworksedi_oftpclient_do_interrupt($res);

Remarks

This method interrupts the current action. If you use SendFile 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 (IPWorksEDI_OFTPClient Class)

Logoff from the OFTP server.

Object Oriented Interface

public function doLogoff();

Object Oriented Interface

public function doSendEndResponse($virtualfilename, $virtualfiledate, $destination, $originator, $creator, $reasoncode, $reasontext, $filehash, $signature);

Procedural Interface

ipworksedi_oftpclient_do_sendendresponse($res, $virtualfilename, $virtualfiledate, $destination, $originator, $creator, $reasoncode, $reasontext, $filehash, $signature);

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 EndTransfer event to False. This instructs the class to not send a response automatically. Within the EndTransfer 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 EndResponse 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:

SendFile Method (IPWorksEDI_OFTPClient Class)

Send the specified file to the server.

Object Oriented Interface

public function doSendFile($localfile, $virtualfilename);

Procedural Interface

ipworksedi_oftpclient_do_sendfile($res, $localfile, $virtualfilename);

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

ValidateCert Method (IPWorksEDI_OFTPClient Class)

Validates the certificate with private key.

Object Oriented Interface

public function doValidateCert();

Procedural Interface

ipworksedi_oftpclient_do_validatecert($res);

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 ImportTrustedCerts 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 TrustedCerts 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.

ValidateRecipientCert Method (IPWorksEDI_OFTPClient Class)

Validates the recipient certificate.

Object Oriented Interface

public function doValidateRecipientCert();

Procedural Interface

ipworksedi_oftpclient_do_validaterecipientcert($res);

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 ServerSFIDCode

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 OFTPConnectionDownloadDirectory 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.

CertificateReceived Event (IPWorksEDI_OFTPClient Class)

Fired when a certificate is received from the remote host.

Object Oriented Interface

public function fireCertificateReceived($param);

Procedural Interface

ipworksedi_oftpclient_register_callback($res, 2, array($this, 'fireCertificateReceived'));

Parameter List

 'certificatefilename'
 'certificateexchangetype'

Remarks

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

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 EndTransfer 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 SendEndResponse 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:

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 SendEndResponse method to send the response at a later time. See SendEndResponse 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 SendEndResponse. See SendEndResponse 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:

Error Event (IPWorksEDI_OFTPClient Class)

Fired when information is available about errors during data delivery.

Object Oriented Interface

public function fireError($param);

Procedural Interface

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

Parameter List

 'errorcode'
 'description'

Remarks

The 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.

Log Event (IPWorksEDI_OFTPClient Class)

Fires once for each log message.

Object Oriented Interface

public function fireLog($param);

Procedural Interface

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

Parameter List

 'loglevel'
 'message'
 'logtype'

Remarks

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

LogLevel indicates the level of message. Possible values are:

Message is the log entry.

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

• "Info"
• "OFTP"

PITrail Event (IPWorksEDI_OFTPClient Class)

Fired when any protocol level communication occurs.

Object Oriented Interface

public function firePITrail($param);

Procedural Interface

ipworksedi_oftpclient_register_callback($res, 7, array($this, 'firePITrail'));

Parameter List

 'direction'
 'data'
 'commandid'
 'commanddescription'

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.

SSLServerAuthentication Event (IPWorksEDI_OFTPClient Class)

Fired after the server presents its certificate to the client.

Object Oriented Interface

public function fireSSLServerAuthentication($param);

Procedural Interface

ipworksedi_oftpclient_register_callback($res, 8, array($this, 'fireSSLServerAuthentication'));

Parameter List

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

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 (IPWorksEDI_OFTPClient Class)

Fired when secure connection progress messages are available.

Object Oriented Interface

public function fireSSLStatus($param);

Procedural Interface

ipworksedi_oftpclient_register_callback($res, 9, array($this, 'fireSSLStatus'));

Parameter List

 'message'

Remarks

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

StartTransfer Event (IPWorksEDI_OFTPClient Class)

Fired when a document starts transferring.

Object Oriented Interface

public function fireStartTransfer($param);

Procedural Interface

ipworksedi_oftpclient_register_callback($res, 10, array($this, 'fireStartTransfer'));

Parameter List

 'direction'
 'localfile'
 'virtualfilename'
 'virtualfiledate'
 'destination'
 'originator'

Remarks

This event fires when a file transfer begins.

Direction specifies if the client or server sent the file.

VirtualFileName holds the filename.

VirtualFileDate holds the date associated with the file in the format "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.

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

Transfer Event (IPWorksEDI_OFTPClient Class)

Fired while a document transfers (delivers document).

Object Oriented Interface

public function fireTransfer($param);

Procedural Interface

ipworksedi_oftpclient_register_callback($res, 11, array($this, 'fireTransfer'));

Parameter List

 'direction'
 'localfile'
 'virtualfilename'
 'virtualfiledate'
 'destination'
 'originator'
 'bytestransferred'
 'text'

Remarks

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

The BytesTransferred parameter contains the number of bytes transferred in this Direction since the beginning of the document text.

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

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

Config Settings (OFTPClient Class)

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