如何使用sails.js访问外部api？

Question

我正在尝试使用sails.js从控制器中的Facebook访问信息.这是我的代码:

module.exports = {


  commonLikes : function(req,res){
    var other_uid = req.param('uid');
    //var me = req.params.user.uid;
    console.log(other_uid);

    User.findOne({uid : other_uid}).done( function(err,data){
        var other = data;

    var http = require('http'), options = {
            host : "https://graph.facebook.com",
            port : 80,
            path : "/"+other.uid+"/likes?access_token="+other.token,
            method : 'GET'
    };

    var webservice_data = "";

    var webservice_request = http.request(options, function(webservice_response)
    {
        webservice_response.on('error', function(e){ console.log(e.message); });
        webservice_response.on('data', function(chunk){ webservice_data += chunk;});
        webservice_response.on('end', function(){res.send(webservice_data);});
        console.log('coucou');
    });



    });
  }

};

虽然http.request函数看起来不起作用,但在尝试访问/ Likes/commonLikes时出现错误？uid = XXXXX.

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: getaddrinfo ENOTFOUND
    at errnoException (dns.js:37:11)
    at Object.onanswer [as oncomplete] (dns.js:124:16)

有谁知道如何使用sails访问外部API？

谢谢,

该host不该包括的协议:

    var http = require('http'), options = {
        host : "graph.facebook.com",
        port : 80,
        path : "/"+other.uid+"/likes?access_token="+other.token,
        method : 'GET'
    };

如果要使用https,请使用https模块代替http,并使用端口443.并且req.end()在完成请求后不要忘记添加.
