问题描述

所以我一直在使用带有 MeteorJS 的 twitter API,我试图做的只是在浏览器上显示 twitter 用户的屏幕名称.这是我到目前为止所做的:

So I've been using the twitter API w/MeteorJS and what I'm attempting to do is just display the screen name of the twitter user on the browser. This is what I have done so far:

Meteor.methods({
  'screenName': function() {
      T.get('search/tweets',
      {
        q:'#UCLA',
        count:1
      },
      function(err,data,response) {
        console.log(data.statuses[0].user.screen_name);
        return data.statuses[0].user.screen_name;
      }
    )
  }
});

所以我从我的 isClient 端调用方法screenName".我从我的客户端这样调用它:

So I call the method 'screenName' from my isClient side. I call it from my client side like this:

  var temp = Meteor.call('screenName');

在服务器端,它在控制台上打印出正确的值,但无法返回该值.它一直显示未定义.

On the server side, its printing out the correct value on console but it is not able to return that value. It keeps displaying undefined.

我是 javascript 初学者,所以我可能犯了一个我没有立即看到的错误,所以如果有人可以帮助我,我将不胜感激.

I am a javascript beginner so I might be making a mistake that I'm not seeing right away so if someone could please help me, I would highly appreciate it.

谢谢!

推荐答案

你需要在调用中放置一个函数才能得到返回.

You need to place a function inside the call to be able to get the return.

Meteor.call(
    'screenName',
    function(error, result){
        if(error){
            console.log(error);
        } else {
            console.log(result);
        }
    }
);

您可以在有关调用函数的文档中阅读更多信息:http://docs.meteor.com/#/full/meteor_call
