How to upload file using restify

Question

I'm trying to upload image file to Rest server(Confluence to be more specific) using Restify module but getting Assertion error. I'm not sure if I'm using right approach for file upload to REST server. Could anyone point me to the right direction?

This is my attempt -

var restify = require('restify');
var header = {'Authorization': 'Basic xxxxx', 'content-type': 'multipart/form-data'};
var client = restify.createJsonClient({
   url: 'http://www.testsite.com',
   version: '*',
   headers: header
});
var image = "c:\\Users\\abc\\Documents\\bbb.jpg";           
var fileStream = fs.createReadStream(image);
var stat = fs.statSync(image);
var size = stat["size"];
var param = "?pageId=123&filename=mynewimage&mimeType=image%2Fjpeg&size=" + size;       
fileStream.pipe(
    client.post("/plugins/drag-and-drop/upload.action"+param, function(err, req, res, obj) {
        if (err) {
            return err;
        }

    })
);  

UPDATE:

This is an assertion error I'm getting assert.js:86

throw new assert.AssertionError({
        ^
AssertionError: body

Solution 1

To send multipart/form-data, you will have to use a library other than restify because it doesn't support that Content-Type.

You could use request which does have support for multipart/form-data http requests built-in.

Solution 2

I was struggling both sending a request containing multipart/form-data and processing this request on an API using restify 5. Following @mscdex answer I came up with the following code that handles both scenarios:

"use strict"

const restify  = require('restify'),
  plugins  = require('restify-plugins'),
  fs       = require('fs'),
  request  = require('request'),
  FormData = require('form-data');

var server = restify.createServer();
server.use(plugins.multipartBodyParser());  // Enabling multipart

// Adding route
server.post('/upload', (req, res, next) =>{
    /**
    * Processing request containing multipart/form-data
    */
    var uploaded_file = req.files.mySubmittedFile;  // File in form

    //Reading and sending file
    fs.readFile(uploaded_file.path, {encoding: 'utf-8'}, (err, data)=>{
        // Returning a JSON containing the file's name and its content
        res.send({
            filename: uploaded_file.name,
            content: data
        });
        next()
    });
});

// Launching server at http://localhost:8080
server.listen(8080, start);

// Client request
function start(){
    // Making a request to our API using form-data library
    // Post file using multipart/form-data
    var formData = {
        mySubmittedFile: fs.createReadStream('/tmp/hello.txt')
    }
    request.post({'url': 'http://localhost:8080/upload', formData: formData}, function(err, res, body){
        console.log("Response's body is: "+ body);
    });
}

I tried not using the libraries form-data and request to only use restify/http but I ended up with a horrible long code.

Thanks for your time!

As of restify 4, this is not true (anymore).

require('restify-plugins') is deprecated use require('restify').plugins
