javascript - Restangular.copy() : route on . one() 对象最终未定义

Question

我在使用 Restangular 的 .one() 和 .put() 函数时遇到问题。当我 Restangular.copy() 我需要处理的元素时，我丢失了 route 值。

如果我手动添加 route 值，我就会让它工作(下面的示例)。

我的计划是在 $stateProvider 中使用解析，但这仍处于测试阶段，这就是我寻求建议/需要帮助的原因。

我做错了什么吗？

API 端:

GET: /api/news/1

响应:

{
  "success":true,
  "status":200,
  "data": [
    {"id": 1, "title":"the title", "author":"the author", "date": 123456789, "contents": "the contents"}
  ]
}

前端:

'use strict';

angular.module('app', ['ui.router', 'restangular'])
.config(['RestangularProvider', '$stateProvider', function (RestangularProvider, $stateProvider) {
  RestangularProvider.setBaseUrl('/api');

  RestangularProvider.addResponseInterceptor(function (data, operation) {
    var extractedData;

    if (operation === 'getList') {
      extractedData         = data.data;
      extractedData.success = data.success;
      extractedData.status  = data.status;
    } else {
      extractedData = data;
    }

    return extractedData;
  });

  $stateProvider.state('news', {
    url: '/news/:id',
    views: {
      'articles': {
        controller: 'NewsCtrl',
        templateUrl: 'news-view.html'
      }
    }
  });
}])
.controller('NewsCtrl', ['$stateParams', 'Restangular', function ($stateParams, Restangular) {

  $stateParams.id = 1; // For the sake of this example

  Restangular.one('news', $stateParams.id).get().then(function (data) {
    console.log(data); // route set to news

    var post   = data.data[0]; // access the response object
    post.title = 'a news title';
    post.put(); // TypeError: undefined is not a function

    var anotherPost   = Restangular.copy(data.data[0]); // using Restangular.copy instead
    anotherPost.title = 'another news title';
    // anotherPost.route = 'news'; // if I add this to anotherPost, put() will work
    anotherPost.put(); // /api/undefined/1 404 (Not found)
  });

}]);

在使用该方法之前，您应该按照这些说明改进实体的解析

https://github.com/mgonto/restangular#my-response-is-actually-wrapped-with-some-metadata-how-do-i-get-the-data-in-that-case

app.config(function(RestangularProvider) {

// add a response intereceptor
RestangularProvider.addResponseInterceptor(function(data, operation, what, url, response, deferred) {
  var extractedData;
  // .. to look for getList operations
  if (operation === "getList") {
    // .. and handle the data and meta data
    extractedData = data.data.data;
    extractedData.meta = data.data.meta;
  } else {
    extractedData = data.data;
  }
  return extractedData;
});

});
