无法使用Node.js从REST调用中获取数据

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

1. 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;

1. 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);
