Unable to get data from REST Calls using Node.js

Question

I am making a REST API call from my php and Node.js application to a particular URL provided by the client which returns a Json object. It works fine from with the PHP. However, I am unable to receive data from my node application? What might be the possible reason can someone help me ?

Note: I have pasted a dummy REST URI for security reasons

It works fine with PHP infact i get the json formatted data in like couple of seconds.

$response = file_get_contents('http://xyz.net/v2_resmgr/providers/pools'); echo $response;

I try the same url using node.js i get a TimeOut error. I also tried setting the timeout but it would still not work.

var job = new CronJob({ cronTime: '0 */3 * * * *', onTick: function () {

  url=   "http://xyznet/v2_resmgr/providers/pools"; 


    var request = http.get(url, function (response) {

      var buffer = "",
        data,
        route;

      response.on("data", function (chunk) {
        buffer += chunk;
      });

      response.on("end", function (err) {
      console.log(buffer);

    });

request.setTimeout( 200000, function( ) {
    // handle timeout here
  console.log("Time Out call to the Rest API");
});

      });

  },
  start: true

});
job.start();

I don't know if this is the answer you are looking for, but life gets easier when you use the 'request' package (https://www.npmjs.org/package/request)

Here is what the code would look like using the request module:

var request = require('request');
request('http://xyznet/v2_resmgr/providers/pools', function (error, response, body) {
  if (!error && response.statusCode == 200) {
    console.log(body) // Print the body of the response.
  }
})

Update: I coded something a little closer to your post. The code below does not use the "request" module and it contacts the server every 3 seconds.

setInterval(function () {
    http.get('http://echo.jsontest.com/key/value', function (response) {
        var responseBody = '';
        response.on('data', function (chunk) {
            responseBody += chunk;
        });
        response.on('end', function () {
            console.log(responseBody);
            var object = JSON.parse(responseBody)
        });
    });
}, 3000);
