javascript - http request from node.js local server port 5000 to 8000 gives error -

i trying make request localhost:8000 localhost:5000 url '/servertest'. socket hang error. how fix this?

server on port 5000 (server process request):

var express = require("express"), http = require('http'); app.get('/servertest', function(req, res){     //authenticate request     //send message     res.writehead(200, {'content-type':'application/json'});     res.end(json.stringify({message:'hello'})); });  app.listen(5000, function() {     console.log("listening on " + port); }); 

server on port 8000 (server makes request):

var express = require("express"), http = require('http'); var port = 8000; app.listen(port, function() {     console.log("listening on " + port);     makeacall(); });   function makeacall(){     var options = {         host:'localhost',         port: 5000,         path: '/servertest',         method: 'get'     };      http.request(options, function(response) {         var str = '';         response.on('data', function (chunk) {             str += chunk;         });          response.on('end', function () {             console.log(str);         });     }); } 

error obtained server hosted @ port 8000:

events.js:72 throw er; // unhandled 'error' event ^ error: socket hang @ createhanguperror (http.js:1442:15) @ socket.socketonend [as onend] (http.js:1538:23) @ socket.g (events.js:175:14) @ socket.eventemitter.emit (events.js:117:20) @ _stream_readable.js:910:16 @ process._tickcallback (node.js:415:13) 

when using http.request(), have @ point call request.end() send request.

note in example req.end() called. http.request() 1 must call req.end() signify you're done request - if there no data being written request body.

http.request(options, function(response) {     // ... }).end(); 

or, get requests, can use http.get() call request.end().

http.get(options, function(response) {     // ... });
