Writing image to local server

A few things happening here:

1. I assume you required fs/http, and set the dir variable 🙂
2. google.com redirects to www.google.com, so you’re saving the redirect response’s body, not the image
3. the response is streamed. that means the ‘data’ event fires many times, not once. you have to save and join all the chunks together to get the full response body
4. since you’re getting binary data, you have to set the encoding accordingly on response and writeFile (default is utf8)

This should work:

var http = require('http')
  , fs = require('fs')
  , options

options = {
    host: 'www.google.com'
  , port: 80
  , path: '/images/logos/ps_logo2.png'
}

var request = http.get(options, function(res){
    var imagedata=""
    res.setEncoding('binary')

    res.on('data', function(chunk){
        imagedata += chunk
    })

    res.on('end', function(){
        fs.writeFile('logo.png', imagedata, 'binary', function(err){
            if (err) throw err
            console.log('File saved.')
        })
    })

})
