Question

I am making a request to the facebook api to get a list of friends. When I make the request through node.js, my request is always truncated. Does anyone understand why the response is being truncated?

Here is the code of my function:

var loadFriends;
loadFriends = function(access_token, callback) {
  var https, options, start;
  https = require('https');
  start = new Date();
  options = {
    host: 'graph.facebook.com',
    port: 443,
    path: '/me/friends?access_token=' + access_token
  };
  return https.get(options, function(res) {
    console.log("Request took:", new Date() - start, "ms");
    res.setEncoding("utf8");
    return res.on("data", function(responseData) {
      var data;
      console.log(responseData);
      data = JSON.parse(responseData);
      return callback(data);
    });
  });
};

The res.on('data') event will happen multiple times as chunks of data arrives; you need to concatenate this together to get the whole response.
