How to write to response from HTTP Client Node.JS

Question

I have the following...

var request = require('request');

exports.list = function(req, res){
  res.send("Listing");
};
exports.get = function(req, res){
  request.get("<URL>", function (err, res, body) {
    if (!err) {
      res.send(body,"utf8");
    }
  });
};

This fails with the following....

TypeError: Object #<IncomingMessage> has no method 'send'

How do I do this?

UPDATE tried to use write instead of send but...

/Users/me/Development/htp/routes/property.js:9
  res.setHeader('Content-Type', 'text/html');
      ^
TypeError: Object #<IncomingMessage> has no method 'setHeader'

Also writing out to the console instead works fine.

Need more information on your query to answer ..... Usage Express framework could be possible solution ..... it makes the work a lot easier — Devrath

What are you using this function for ? res.send is from express API. Are you using that ? — user568109

I am using express, I will try using the commands for non-express as listed below and see if that works. — Jackie

Problem was with scope of variables, my response output was the same name as the response object I got back in my callback. Changing this around (resp vs res) made it work....

exports.get = function(req, res){
  request.get("<url>", function (err, resp, body) {
    if (!err) {
      res.send(body);
    }
  });
};

are you using express? the response object passed to the http.createServer() callback function, does not have a req.send() method, afaik req.send is added by Express. congrats on solving your problem!

As stated in other comments yes I am using express. Thanks for trying to help!

What you are trying to do, is to make Request > Response server. But you are using Request module, that allows to get stuff rather than respond.

What you need is http or better get express.js and use it, as it is straight forward and well popular web framework for exactly what you need.

See my answer it had nothing to do with the framework, I am extremely familiar with express and have used it on multiple projects. The problem was variables hiding each other.

I wasn't aware OP is using Express. You will encounter a similar error if you attempt to use req.send with the vanilla HTTP module instead of Express.

var http = require('http');    
function requestHandler(req, res){
  //res.send(200, '<html></html>'); // not a valid method without express
  res.setHeader('Content-Type', 'text/html');
  res.writeHead(200);
  res.end('<html><body>foo bar</body></html>');
};
http.createServer(handler).listen(3000);
