如何使用Express在NodeJS中的GET请求中发出GET请求 [英] How to make GET request inside a GET request in NodeJS using Express

问题描述

基本上，我试图在我的CallBack GET方法中从Facebook获取访问令牌.下面是我的代码.

Basically, I'm trying to get Access Token from Facebook in my callBack GET method. Below is my code.

getAccessToken.实施它的正确方法是什么?

getAccessToken is not called at all. What's the right way to implement it?

app.get('/fbcallback', function(req, res) {


  var code = req.query.code;

  var getAccessToken =  'https://graph.facebook.com/v2.12/oauth/access_token?'+
   'client_id='+client_id+
   '&redirect_uri='+redirect_uri+
   '&client_secret='+client_secret+
   '&code='+code;


   app.use(getAccessToken, function(req, res) {

        console.log('Token Call');

   });


});

推荐答案

您不应在呼叫中使用app.use.

您必须尝试执行以下操作.在get调用中进行另一个get调用以获取令牌.

You must be trying to do something like below. Inside get call make another get call for getting token.

var request = require('request');

app.get('/fbcallback', function (req, res) {
    var code = req.query.code;
    var getAccessToken = 'https://graph.facebook.com/v2.12/oauth/access_token?' +
        'client_id=' + client_id +
        '&redirect_uri=' + redirect_uri +
        '&client_secret=' + client_secret +
        '&code=' + code;

    request(getAccessToken, function (error, response, body) {
        console.log('error:', error); // Print the error if one occurred
        console.log('statusCode:', response && response.statusCode); // Print the response status code if a response was received
        console.log('body:', body); // Print the HTML for the Google homepage.
    });
});
