Restangular：用的GetList含有对象的嵌入式阵列

问题描述

在我AngularJS项目中，我尝试使用Restangular的GetList方法，但由于API响应不直接数组它返回一个错误，但包含数组的对象。

In my AngularJS project I'm trying to use the Restangular getList method but it's returning an error because the API response is not directly an array but an object containing an array.

{
  "body": [
    // array elements here
  ],
  "paging": null,
  "error": null
}

该Restangular错误消息是：

The Restangular error message is:

Error: Response for getList SHOULD be an array and not an object or something else

是否有可能告诉Restangular，它的寻找的阵列是体属性里面呢？

推荐答案

是的，请参阅Restangular文档。您可以配置Restangular像这样：

Yes, see the Restangular documentation. You can configure Restangular like so:

rc.setResponseExtractor(function(response, operation) {
    if (operation === 'getList') {
        var newResponse = response.body;
        newResponse.paging = response.paging;
        newResponse.error = response.error;
        return newResponse;
    }
    return response;
});

的修改的：现在看来Restangular的API改变了，好了，而且，目前的方法是使用的 addResponseInterceptor 的。有些调整可能需要传递的函数。

Edit: It seems Restangular's API is now changed, for the better, and that the current method to use is addResponseInterceptor. Some adjustments might be needed to the function passed.
