How to upload a file using
I am trying to upload an image file to a Rest server (a more specific variant of Confluence) using the Restify module, but getting an Assertion error. I'm not sure if I'm using the correct approach for uploading files to a REST server. Can anyone point me in 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 the assertion error I receive assert.js: 86
throw new assert.AssertionError ({
^

I was trying to send a request containing multipart/form-data
and process that request in the API with restify 5
. Following @mscdex's 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 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 body is: "+ body);
});
}
Using:
- form-data@2.2.0
- request@2.81.0
- restify@5.0.1
- restify-plugins@1.6.0
- node @ 6.11.1
I tried not using libraries form-data
and request
only using restify / http, but I ended up with awful long code.
