使用订阅配置instagram-node-lib

Question

我希望在某个标签上做实时更新，并在屏幕上打印图片。我有问题设置我的node.js服务器使用instagram-node-lib模块。但我仍然收到一个错误时，运行文件(节点服务器.js);

https://github.com/mckelvey/instagram-node-lib

这是我的实现(server.js使用express 3.5.1):

var express = require("express");
var app = express();
var port = process.env.PORT || 3000;
var io = require('socket.io').listen(app.listen(port));
var Instagram = require('instagram-node-lib');
var http = require('http');
var request = ('request');
var intervalID;
var pub = __dirname + '/public',
    view = __dirname + '/views';
var clientID = '*****',
    clientSecret = '*****';
Instagram.set('client_id', clientID);
Instagram.set('client_secret', clientSecret);
Instagram.set('callback_url', 'http://my_url.com/callback');
Instagram.set('redirect_uri', 'http://my_url.com');
Instagram.set('maxSockets', 10);
Instagram.subscriptions.subscribe({
  object: 'tag',
  object_id: 'lol',
  aspect: 'media',
  callback_url: 'http://my_url.com/callback',
  type: 'subscription',
  id: '3'
});
app.configure(function(){
    app.use(express.bodyParser());
    app.use(express.methodOverride());
    app.use(app.router);
    app.use(express.static(pub));
    app.use(express.static(view));
    app.use(express.errorHandler());
});
app.get('/callback', function(req, res){
  Instagram.subscriptions.handshake(req, res);
});
app.post('/callback', function(req, res) {
    var data = req.body;
    // Grab the hashtag "tag.object_id"
    // concatenate to the url and send as a argument to the client side
    data.forEach(function(tag) {
      var url = 'https://api.instagram.com/v1/tags/' + tag.object_id + '/media/recent?client_id=******';
      sendMessage(url);
    });
    res.end();
});
console.log("Listening on port " + port);

一切似乎都很好，但当运行命令(节点服务器.js)我得到:

   info  - socket.io started
connect.multipart() will be removed in connect 3.0
visit https://github.com/senchalabs/connect/wiki/Connect-3.0 for alternatives
connect.limit() will be removed in connect 3.0
Listening on port 3000
APISubscriptionError occurred: Invalid response in _request

(我也有socket。里面有很多东西，但我把它放在这里，专注于问题。

APISubscriptionError与我尝试和执行的订阅数量直接相关。在这种情况下，只考虑标记"lol"的那个。

我能够找到我的问题，这是无关的Instagram-node-lib(这是一个生病的库)。我需要将所有url定义为http://MY_URL.com:3000，因为我在端口3000上运行。当尝试在我的回调url中订阅时，这会产生冲突。为了使它不需要使用:3000后缀，似乎我需要通过nginx为端口80创建一个代理来运行节点。
