FAQ
Hi. I'm trying to create a component in Node.js that consumes two external
APIs.

The code of my component is something like:

var api1 = require('./api1');
var api2 = require('./api2');
var component = { api1: api1, api2: api2 };
module.exports = component;
--------------------

api1 is something like this:

var api1 = { testFunc: function(stuff,callback){ // do http request &
callback(result) } }
module.exports = api1;

--------------------

I've one endpoint on nodejs where i'm trying to use this component, like
this:

var component = require('../../component');
component.api1.testFunc(1, function(result) {return res.json(200,
result.data);});

--------------------

It works fine for the first time. On the second call i have no response
from server.
Newbie here. Can someone help me please?

Thanks in advance

    Can you include the code for

    // do http request & ...

    ? And what is the code if do http request fails?

    Another point: you don't need

    return res.json ..;

    Change to

    res.json...;

    Its like this. Thank you.
    (can view the code here: http://www.codeshare.io/rA1w9)


    var testFunc : function(stuff, callback) {

         var result = {
             error: false,
             data: ''
         };

         var post_body_xml = xmlbuilder.buildObject(post_body);

         // An object of options to indicate where to post to
         var post_options = {
             host: api.endpoint,
             path: api.path,
             port: '80',
             method: 'POST',
             headers: {
                 'Content-Type': 'text/xml',
                 'Content-Length': post_body_xml.length
             }
         };

         // Set up the request
         var post_req = http.request(post_options, function(res) {

             res.setEncoding('utf8');

             res.on('data', function(chunk) {
                 result.data += chunk;
             });

             res.on('error', function(e) {

                 console.log('problem with request: ' + e.message);
                 result = {
                     error: true,
                     data: e.message
                 };

             });

             res.on('end', function() {

                 xmlparser.addListener('end', function(json_result) {
                     result.data = json_result;
                     //console.log(result);
                     callback(result);
                 });

                 xmlparser.parseString(result.data);

             });

         });

         // post the data
