如何使用sails.js访问外部API? [英] How to access external api using sails.js?

问题描述

我正在尝试使用sails.js从控制器内的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');
    });



    });
  }

};

http.request函数似乎无法正常工作，尝试访问/Likes/commonLikes?uid = XXXXX时出现错误.

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)

有人知道我如何使用Sails访问外部API吗?

谢谢

解决方案

host不应包含以下协议:

    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模块而不是http，并使用端口443.完成请求后，请不要忘记添加req.end().

I am trying to access information from facebook within a controller using sails.js. Here is my code:

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');
    });



    });
  }

};

The http.request function doesn't look to work though and I get an error when trying to access /Likes/commonLikes?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)

Does anyone knows how I can access an external API using sails?

Thanks,

The host shouldn't include the protocol:

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

If you want to use https, use the https module instead of http, and use port 443. And don't forget to add req.end() when you're done with the request.
