AngularJS transformResponse [英] AngularJS transformResponse

问题描述

在angularjs资源，我想我的JSON数据转换成JS对象

In angularjs resource, I would like to convert my json data into JS objects

//Complex object with inheritance chain
function Car(year, make){
    this.make = make;
    this.year = year;
}


var carResource = $resource("/api/car/id", {id: '@id'},
    {
        get: {
            method: 'GET',
            transformResponse: function(data, headersGetter){
                return new Car(data.make, data.year);
            }
        }
    }
)

不过，这似乎并没有被发生

However this does not seem to be happening

我所取回一个 $资源对象即属性制作和年设置正确，然而， $资源原型返回的对象分

What I am getting back is a $resource object meaning that the properties make and year are set correctly, however the prototype of the returned object points to $resource

有没有一种方法，我可以我的JSON数据直接映射到我自己的对象？

Is there a way where I can map my json data directly to my own objects?

或将我写我自己的'资源'的实施？

Or will I have to write my own 'resource' implementation?

推荐答案

在自定义自定义的配置对象$资源的行为，该对象实际上是传递给底层 $ HTTP 服务。所以，如果你指定 transformResponse 的回调，这将是 $ HTTP 执行层面，你的改造的结果将被传递回至$资源。

transformResponse is executed on $http level.

When you customise $resource actions with custom config object, that object is actually passed on to the underlying $http service. So if you specify a transformResponse callback, it will be executed on $http level, and the results of your transformation will be passed back on to $resource.

$资源服务将从您的响应数据（这已经是由 transformResponse 回调转化），这新的对象将是$资源本身的一个实例，实例化新对象

$resource service will instantiate new object from your response data (which is already transformed by the transformResponse callback) and this new object will be an instance of the $resource itself.

所以，你的车对象的会是一个实例车，但只一会儿，直到它的属性都复制到新的 $资源对象。

So, your car object will be an instance of the Car, but only for a moment, until it's properties are copied into a new $resource object.

下面是该过程的一个简单的观点：

Here's a simplistic view of the process:

1. $资源服务发起请求


2. $ HTTP服务发送请求和接收响应


3. $ HTTP服务将响应转换（现在的反应是车的实例）


4. $资源服务接收变换的响应（由$ HTTP）


5. $资源服务使用变换的响应性（结果现在是$资源的实例）
让自己的一个实例

1. $resource service initiates request
2. $http service sends request and receives the response
3. $http service transforms the response (response is now instance of Car)
4. $resource service receives the transformed response (from $http)
5. $resource service makes an instance of itself using transformed response properties (result is now instance of $resource)

反正我不推荐装饰或延长$资源服务，因为它更简单使用$ http服务编写你自己的实现。

Anyway, I don't recommend decorating or extending the $resource service, because it's simpler to write your own implementation using $http service.
