Send HTTP request from different IPs in Node.js

Question

Is there a way to send an HTTP request with a different IP from what I have in Node.js?

I want to send a request from an IP that I choose before, and not from the IP of the server or from my computer’s IP.

I know that Tor Project does this kind of manipulation, but I didn't find any library that Tor uses to do this stuff.

Is there any API or Node.js module that Tor uses to handle this kind of private browsing in Node.js?

Answer 1

In the node http module there is a localAddress option for binding to specific network interface.

var http = require('http');

var options = {
  hostname: 'www.example.com',
  localAddress: '202.1.1.1'
};

var req = http.request(options, function(res) {
  res.on('data', function (chunk) {
    console.log(chunk.toString());
  });
});

Check out Mikeal's Request on Github.

Tor uses SOCKS5 and these two modules can help: socks5-http-client and socks5-https-client

require('socks5-http-client').request(options, function(res) {
  console.log('STATUS: ' + res.statusCode);
  console.log('HEADERS: ' + JSON.stringify(res.headers));
  res.setEncoding('utf8');
  res.on('data', function (chunk) {
    console.log('BODY: ' + chunk);
  });
});

Another option is to use a free web proxy, such as the Hide My Ass web proxy. They also provide a list of ip:port proxies which you can use. Both http, https and even SOCKS4/5. Either use the above modules or simply configure your web browser to use one of them.

You could even setup your own private http proxy node app and deploy on Heroku. I found a ton of easy to follow examples on Google.
