node-red-contrib-ftp-download

A Node-RED node for FTP Downloads.

Install

Run the following command in the root directory of your Node-RED install

npm install node-red-contrib-ftp-download

Usage

This node allows you to download one or more files within a single connection.

Files

The file paths may be defined in one of a number of ways.

• msg.: A variable on the msg object that contains an array of Strings or source Objects.
• flow.: A variable on the flow context object that contains an array of Strings or source Objects.
• global.: A variable on the global context object that contains an array of Strings or source Objects.
• json: A JSON array of Strings or source Objects.
• string: A singular path String.

ex:

global.test = ["/path/to/ftp.file", "/path/to/another/ftp.file"];

// or

global.test = [
    {
        "src": "/path/to/ftp.file",
        "dest": "/path/to/local.file"
    }, {
        "src": "/path/to/another/ftp.file",
        "dest": "/path/to/another/local.file"
    }
];

Directory

The directory path may be defined in one of a number of ways.

• msg.: A variable on the msg object that contains a local path String.
• flow.: A variable on the flow context object that contains a local path String
• global.: A variable on the global context object that contains a local path String
• string: A singular local path String.

The files defined in the files field will be downloaded into the directory field, if the files field is an array of objects with dest fields set. The final destination will be directory + "/" + file.dest

Output

An Array of local file path Strings. The "Output" variable may be set to define where the Array will be placed, by default msg.payload is used.
