Transfer attachments from APIs: You may want to download attachments from APIs and synchronize them to the FTP server/local system/other business systems (through APIs) for archiving.
Relocate files on the FTP server/local system: You may want to back up a file from an FTP server to another folder on the server and delete the original file.
You can use the File Transfer node to download files from and upload files to multiple positions, such as APIs, local systems, and FTP/SFTP servers.
1. This node is used to synchronize files, not extracting data from files.
2. This node is not subject to the dirty data threshold and will report an error upon detecting a dirty file.
You must create the corresponding data connection to transfer files from/to the local directory or the FTP/SFTP server. For details, see Data Connection of Local Server Directory and FTP/SFTP Data Connection.
API
Select API Input from the drop-down list of Data Source to fetch files from an API. The response data must be a file stream. (The file name extension is not restricted.) Otherwise, the node fails to run and reports an error.
FTP/SFTP
Choose File Input > FTP/SFTP from the drop-down list of Data Source to fetch files from the specified server.
You can set Read Method to Read File or Read Folder.
Select Read File to read a specific file. You can use parameters when entering the file address.
1. You can enter the filename extension (not case-sensitive) to limit the type of files to be read automatically from the FTP/SFTP server or uploaded manually from the local system. Separate multiple values by comma (,).
2. There is no restriction on the suffix entered in Filename Extension.
Select Read Folder to read files from a specific folder. You can use parameters when entering the folder address.
If it is selected, files in the subfolder will be read.
If it is unselected, files in the subfolder will not be read.
This item appears after you select Read Folder.
You can configure filtering conditions for files to be read in the folder.
The condition is effective only after the folder address is set.
You can add conditions to specify names (including filename extensions) and the modification time of the file to be read.
Conditions for File Name include In, Not In, Contain, Not Contain, Begin With, End With, Not Begin With, and Not End With.
Conditions for File Modification Time include Between, Not Between, Before, After, Equal To, and Not Equal To.
Referencing parameters is supported. For details about the judgment logic, see Judgment Logic Description.
Notes:
If you select Read Subfolder and files with the same name and different paths exist in the selected folder, the names of target files are the original file names prefixed with Subfolder name_ for distinguishing. For example, Folder A has the following structure.
Folder A/Subfolder B/File C
Folder A/Subfolder B/File D
Folder A/File C
After a successful file transfer, file names in the target location are Subfolder B_File C, Subfolder B_File D, and File C. If a file name already exists in the target location, the duplicate handling strategy will be followed.
Local Server Directory
Choose File Input > Local Server Directory from the drop-down list of Data Source to fetch files from the FineDataLink server.
You can set Read Method to Read File or Read Folder. Referencing parameters in the address is supported.
You can only select the folder of the entered data connection and its subfolders after selecting Read Folder.
Select API Output from the drop-down list of Data Source to upload a file to an API. The configuration method is the same as that of the API Output operator, except that only binary Body is supported here.
The obtained file defaults to the pre-downloaded file stream.
This method is typically used to upload files. There is no key-value pair, so only one file can be uploaded at a time.
Choose File Output > FTP/SFTP from the drop-down list of Data Source to upload files to the specified server.
Enter the folder address and set the target file name and the duplicate handling strategy, as shown in the following figure.
Set the file output path, whose parent directory defaults to the directory of the selected data connection.
You can select the file address or use parameters.
Keep the file address empty before entering the parameter.
You can select the file directory from the drop-down list.
You can use the original file name or customize the file name.
Select Custom to customize the file name (which cannot be empty). The input box is empty by default. You can enter the parameter or a mix of the parameter and text.
The strategy for handling files with duplicate names when they are written to the server includes Stop Outputting and Report An Error, Keep Both Files, and Overwrite Target File.
The configuration method is the same as uploading files to the FTP/SFTP server, except that the folder address must be the data connection folder or its subfolder.
