Unable to save remote image using node.js and request

Question

I want to save an image with node.js and a query library . So far I have this simple code:

var request = require('request'); var fs = require('fs'); request('http://upload.wikimedia.org/wikipedia/commons/8/8c/JPEG_example_JPG_RIP_025.jpg', function(error, response, body) { // further logic that decides // whether or not the image will be saved fs.writeFile('downloaded.jpg', body, function(){}); }); 

But that will not work. The image always arrives corrupt. I assume this is a coding error, but I cannot figure out how to fix this.

Answer 1

 var request = require('request'), fs = require('fs'), url = 'http://upload.wikimedia.org/wikipedia/commons/8/8c/JPEG_example_JPG_RIP_025.jpg'; request(url, {encoding: 'binary'}, function(error, response, body) { fs.writeFile('downloaded.jpg', body, 'binary', function (err) {}); }); 

Answer 2

 var fs = require('fs'), request = require('request'), url='http://upload.wikimedia.org/wikipedia/commons/8/8c/JPEG_example_JPG_RIP_025.jpg'; request(url).pipe(fs.createWriteStream('downloaded.jpg')); 

Answer 3

This is how I did it using stream and pipe , (I used express , but you may not need this)

 var express = require('express'); var app = express(); var filesystem = require('fs'); var https = require('https'); var download = function(url, dest, cb) { var file = filesystem.createWriteStream(dest); var request = https.get(url, function(httpResponse) { httpResponse.pipe(file); file.on('finish', function() { console.log("piping to file finished") file.close(cb); // close() is async, call cb after close completes. }); }).on('error', function(err) { // Handle errors filesystem.unlink(dest); // Delete the file async. (But we don't check the result) if (cb) cb(err.message); }); }; app.get('/image', (req, res) => { download('https://lastfm-img2.akamaized.net/i/u/64s/15cc734fb0e045e3baac02674d2092d6.png', 'porcupine.png', () => {console.log("downloaded to porcupine.png")}) }) 

When I start using node server.js and click on url localhost:3000/image , it will download and save the file in porcupine.png in the base directory.
