Nodejs : Redirect URL

Question

I\'m trying to redirect the url of my app in node.js in this way:

// response comes from the http server
response.statusCode = 302;
response.setHeader(\"Loca         


        

Answer 1

What happens if you change it to 307 instead?

Answer 2

This issue may also depend on the type of request you are handling. A POST request cannot be redirected using the header. For example, a first-time visitor from to your app in FB will most-likely be coming via a "signed request" POST and therefore a redirect will not work.

Answer 3

Looks like express does it pretty much the way you have. From what I can see the differences are that they push some body content and use an absolute url.

See the express response.redirect method:

https://github.com/visionmedia/express/blob/master/lib/response.js#L335

// Support text/{plain,html} by default
  if (req.accepts('html')) {
    body = '<p>' + http.STATUS_CODES[status] + '. Redirecting to <a href="' + url + '">' + url + '</a></p>';
    this.header('Content-Type', 'text/html');
  } else {
    body = http.STATUS_CODES[status] + '. Redirecting to ' + url;
    this.header('Content-Type', 'text/plain');
  }

  // Respond
  this.statusCode = status;
  this.header('Location', url);
  this.end(body);
};

Yes it should be full url in setHeader.

  res.statusCode = 302;
  res.setHeader('Location', 'http://' + req.headers['host'] + ('/' !== req.url)? ( '/' + req.url) : '');
  res.end();

server = http.createServer(
    function(req, res)
    {
        url ="http://www.google.com";
        body = "Goodbye cruel localhost";
        res.writeHead(301, {
             'Location': url,
             'Content-Length': body.length,
             'Content-Type': 'text/plain' });

        res.end(body);
    });
