声明中angularJS承诺名为成功/错误回调 [英] declaring a promise in angularJS with named success/error callbacks

问题描述

我试图做的非常类似$ http服务的东西。从我的理解$ HTTP返回一个承诺的对象。

I am trying to do something very similar to the $http service. From my understanding $http return a promise object.

在使用它的语法是：

$http(...).success(function(data)) {
   //success callback
}).error(function(data)) {
   //error callback
})

我想这样做是一样的，但考虑我的API是GetUserProfile，所以我希望有语法：

I would like to do just the same but consider my API is GetUserProfile, so I wish to have the syntax :

GetUserProfile(...).success(function(data) {
   // success callback
}).error(function(data)) {
   // error callback
})

我怎么能做到，使用一个承诺？

how can I accomplish that using a promise ?

推荐答案

与开放源代码的好处是，你可以阅读源代码。这里的$ http服务是如何做的：

The nice thing with open-source is that you can read the source. Here's how the $http service does it:

  promise.success = function(fn) {
    promise.then(function(response) {
      fn(response.data, response.status, response.headers, config);
    });
    return promise;
  };

  promise.error = function(fn) {
    promise.then(null, function(response) {
      fn(response.data, response.status, response.headers, config);
    });
    return promise;
  };
