Node-Red Node HTTP with Multi-Part Support

This node is a version of the Node-Red HTTP-in node that includes support for multi-part forms and files using Multer.

Use this module anywhere you would use the node-red-http-in node and would like to have file support. The module will usually be used with the POST method that contains a form with a file upload button.

Installation

``sh
$ npm install node-red-contrib-http-multipart
`
node-red should automatically detect the new node upon restarting of the server.

Usage


Once installed, a new http-multipart node will be available in your node-red nodes panel. Drag the node onto the flow sheet and use as you would the other http-in node. Output of the node will be a message which contains the files in a msg.req.files object.

To retrieve the file object, you can add a function node to the out port of the node that reads the msg.req.files object.

Configuration

Configuration of this node is the same as the node-red-http-in node with the exception of the fields config option. fields refers to the fields in the form that will contain files.

Eg. For a form with the following field
`html

`
the fields section of your node configuration would contain the following:
`
[ { "name": "myUploadedFile"} ]
`
The fields configuration is passed directly to the Fields option in the multer plugin, so you can use any options that would work for multer in the configuration area.
ex:
`
[
{ name: 'avatar', maxCount: 1 },
{ name: 'gallery', maxCount: 8 }
]
`
#### Example
With HTML like the following:
`html
...





You can upload to a node with the following configuration:
`javascript
[{ "name": "myFile" }]
`

and access the files using the following function on the out port of the node
`javascript
var fields = msg.req.fields;
msg.fields = Object.keys(fields);
var myFile = fields["myFile"][0];
msg.localFilename = myFile.path
...
``
All of the available properties of the file object can be found in the Multer documentation.
