FTPS Client

Connect

It establishes the SSL/TLS connection to the server using the authentication parameters defined on the SDT FtpsOptions.

Connect(FtpsOptions)

• Input FtpsOptions: SDT FtpsOptions with authentication configuration preloaded
• Returns: Boolean true if the connection was successful.

Example:

&success = &FtpsClient.Connect(&FtpsOptions)

Get

Downloads a file from the remote FTPS server to the client's machine using an already open connection.

Get(remoteFilePath, localDirectory)

• Input remoteFilePath: VarChar(9999), path relative to the working directory (pwd) including filename and extension.
• Input localDirectory: VarChar(9999), an absolute local path to save the downloaded file.
• Returns: Boolean true if the operation was successful.

Example:

&success = &FtpsClient.Get("/ftpsfolder/samplefile.txt", "C:\Temp\")

Put

Uploads a file from the local client's machine to the FTPS server using an already open connection.

Put(localFilePath, remoteDirectory)

• Input localFilePath - VarChar(9999), absolute local path to the file including filename and extension.
• Input remoteDirectory - VarChar(9999), a path relative to the working directory (pwd).
• Returns: Boolean true if the operation was successful.

Example.

&success = &FtpsClient.Put("C:\Temp\samplefile.txt", "/ftpsfolder")

GetWorkingDirectory

Returns the default remote server working directory (command pwd).

GetWorkingDirectory()

• Returns VarChar(9999) 

Example:

&directory = &FtpsClient.GetWorkingDirectory()

Disconnect

Closes the FTPS connection.

It is mandatory as good programming practice after finishing using the channel and as a security measure.

Disconnect()

• It does not receive any parameters and does not return any value.

Example

&FtpsClient.Disconnect()

Rm

This method is available since GeneXus 18 Upgrade 2

Remove/delete a file from the remote FTPS server using an already open connection.

Rm(remoteFilePath)

• Input remoteFilePath: VarChar(9999), path relative to the working directory (pwd) including filename and extension.
• Returns: Boolean true if the operation was successful.

Example:

&success = &FtpsClient.Rm("/ftpsfolder/samplefile.txt")
