How to redirect an HTTP request in node js

Question

I want to take the request, forward it to another URL and return the result of the forwared request.

This is my code:

const http = require('http'),
      server = http.createServer().listen(3000);

const baseUrl = 'foo.bar';

server.on('request', (req, res) => {
    req.headers.host = baseUrl;

    var connector = http.request(req, (resp) => {
        resp.pipe(res);
    });

    req.pipe(connector);
});

Unfortunately, I get an error that the socket hung up.

Error: socket hang up
    at createHangUpError (_http_client.js:203:15)
    at Socket.socketOnEnd (_http_client.js:288:23)
    at emitNone (events.js:72:20)
    at Socket.emit (events.js:166:7)
    at endReadableNT (_stream_readable.js:903:12)
    at doNTCallback2 (node.js:439:9)
    at process._tickCallback (node.js:353:17)

Does anyone know what I'm doing wrong?

Answer 1

Try setting up a new query object manually and do not change the object req.

It works:

const http = require('http'),
    server = http.createServer().listen(3000);

const baseUrl = 'www.i.ua';

server.on('request', (req, res) => {
  var connector = http.request({
    host: baseUrl,
    path:'/',
    method: 'GET',
    headers: req.headers
  }, (resp) => {
    resp.pipe(res);
  });

  req.pipe(connector);
});

So you should have something like this:

const http = require('http'),
    server = http.createServer().listen(3000);

const baseUrl = 'radio.i.ua';

server.on('request', (req, res) => {
  var connector = http.request({
    host: baseUrl,
    path: req.url,
    method: req.method,
    headers: req.headers
  }, (resp) => {
    resp.pipe(res);
  });

  req.pipe(connector);
});
