Uploads and downloads data from an FTP server. The transformer allows uploads from attribute values or from a file. Remote files may be downloaded into a local file, or into a feature attribute. The transformer also supports deleting remote files.
The transformer supports the ftp, ftps and sftp protocols.
Features which have been successfully processed will be output through this output port.
If an FTP operation fails for any reason, the feature will be output through this output port. An error message will be placed in the attribute named in the Error Attribute parameter.
This parameter is used to specify a remote file on the FTP server.
The Transfer Type parameter indicates the type of FTP operation the transformer will execute. The set of possible operations is:
- Download to an Attribute: The remote file specified in the URL parameter will be downloaded into the attribute specified in the Target Attribute parameter. The attribute will be tagged with the encoding named in the Attribute Encoding parameter – no actual encoding conversion will be performed.
- Download to a File: The remote file specified in the URL parameter will be downloaded to the local file named in the Target File parameter. If the local file already exists, it will be overwritten with the contents of the remote file. The value of the File Path Attribute will be set to the path of the downloaded file.
- Upload from an Attribute: The data given in the Upload Data parameter will be uploaded to the remote file specified in the URL parameter.
- Upload from a File: The local file named in the File to Upload parameter will be uploaded to the remote file specified in the URL parameter. If the local file does not exist, the feature will be output through the <Rejected> output port.
- Delete a Remote File: The remote file specified in the URL parameter will be deleted from the FTP server.
Use this parameter to control the type of connection which is used to transfer data between FME and the FTP server. When Active is selected, the server will connect to FME when transferring data. When Passive is selected, the connection is reversed and FME connects to the server. Some servers and network firewalls only allow one of these connection types, so a failed transfer can sometimes be fixed by changing the connection type. The most commonly used connection type is Passive, which is the default value of this parameter.
An FTP upload or download can be performed in binary mode or ASCII mode. When using ASCII mode, the FTP server may perform some text conversions. For example, to convert UNIX line terminators into Windows line terminators, or vice-versa. When using binary mode, all data will be transferred without any modifications. By default, binary mode is used, which should be acceptable in almost all situations.
If this parameter is set to Yes, the transformer will verify SSL certificates when connecting to an FTPS server. This is done in two stages:
- Ensure that the certificate is for the host we are trying to connect to.
- Ensure that the certificate is valid.
Features output though the <Rejected> output port will have an error message in the attribute named by this parameter.
This parameter determines how the connection to the FTP server is authenticated.
This is the username of the user which will be accessing the FTP server. This parameter is only used when Authentication Type is not None / Anonymous.
This is the password of the user which will be accessing the FTP server. This parameter is only used when Authentication Type is Password.
Select the proxy type which will be used in this transformer. If None is selected, no proxy will be used. If Use FME Network Proxy Settings is selected, the proxy settings defined in the FME Settings page will be used. If Native FTP Proxy is selected, the transformer will use an FTP proxy configured using the other parameters in this section.
This is the hostname of the proxy server which will be used.
This is the username of the user which will be accessing the proxy server. This can be different than the username used when accessing the FTP server.
This is the password of the user which will be accessing the proxy server.
Editing Transformer Parameters
Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
