无极Angular.js不返回预期的文件 [英] Promise not returning the intended file in Angular.js

问题描述

function getJSON(url){
  return $http.get(url).success(function(response){

    var result = response['entries'][0];
    return result;

  });
};

我以为$ HTTP返回的承诺，所以我做了以下内容：

I thought that $http returned promises, so I did the following:

getJSON(url).then(function (result) {
  console.log(result);
})

然而，当我登录的结果，我不明白我登录超时功能里面的JSON文件，而是我得到一个HTML的响应文件。这是我结束了：

However, when I log the result, I don't get the JSON file I logged inside the timeout function, but instead I get a HTML response file. This is what I ended up with:

Object {data: Object, status: 200, config: Object, statusText: "OK"}

你知道为什么它做了什么，我能做得到我在$超时功能，而不是记录的JSON文件？

Do you know why it does that and what I can do to get the JSON file I logged in the $timeout function instead?

推荐答案

你的方法改成这样：

function getJSON(url){
  return $http.get(url).then(function(response){

    var result = response.data['entries'][0];
    return result;

  });
};

PS：最初你在问题中有一个 $超时，事情是不同的。在这种情况下 .success 应实际工作。唯一的问题是，你不能继续链接在 .success 电话后承诺

PS: initially you had a $timeout in the question and things were different. In this case .success should actually work. The only problem is that you can't continue chaining promises after the .success call
