为什么这个回调函数没有执行？

Question

我一直有这个问题。好像它有效一段时间然后没有太多的押韵或理由就打破了它。

router.get('/home/', function(req, res, next) {

  var code = req.query.code;
  console.log("acquired code from SC");

  req.SC.authorize(code, function(err, accessToken) {
    if ( err ) {
      throw err;
    } else {
      console.log("traded code for access token");
      req.session.oauth_token = accessToken;
      // Client is now authorized and able to make API calls
      //res.render('home', { token: accessToken });
      soundcloud.getLoggedInUser(accessToken, function(user){
        console.log("done getting user from SC");
      });
    }
  });

});

这是getLoggedInUser函数。

//get data for the user who is logged in
function getLoggedInUser(accessToken, done){
    var href = 'https://api.soundcloud.com/me?oauth_token=' + accessToken;
    getRequest(href, done);
}

//used for get requests to soundcloud API
function getRequest(href, done){
    console.log(href);
    requestify.get(href).then(function(response){
        console.log(done);
        done(response.getBody());
    });
}

这是输出。

acquired code from SC
traded code for access token
https://api.soundcloud.com/me?oauth_token=
[Function]

我猜这是我的节点/快速设置的问题，而不是这个代码本身的问题。有什么想法吗？
