$ resource：包含一个对象但得到一个数组的预期响应

标签： javascript json angularjs

我知道这个问题已经存在于SO（就像这里：Error in resource configuration. Expected response to contain an object but got an array），即使我几天前已经遇到过这个错误，我也没有找到我为什么会这样做的原因。我现在得到它。

一方面，我在Node Express中有一个RESTful API。它让我可以访问数据库，我试图获取一些数据。使用特定$resource请求时，我获得此JSON（使用Postman测试）：

 [
   {
    "ref": 2,
    "type": "string here",
    "matriculeMD": 4567,
    "name": "William",
    "date": "2016-09-14T22:00:00.000Z",
    "client": 1
   },
   {
    "ref": 4,
    "type": "string here",
    "matriculeMD": 1589,
    "name": "Averell",
    "date": "0000-00-00",
    "client": 1
   }
 ]

另一方面，我有一个Angular JS应用程序。这个使用工厂从API获取数据：

 .factory('Things', ['$resource', function($resource) {

    return $resource(

        'api_url/:client_id',
        {client_id: '@client_id'}, // getting some data from an ID
        {'query' : {
                        method : 'GET', // ofc, it's a get request in the API
                        isArray : false // to be sure to get an object and not an array
                    }
        }

我还有一个使用这个工厂的控制器，试图用param执行查询：

 app.controller('ctrl', ['$scope','Things', function ($scope,$things) 

    {
      $scope.thing = $things.query({},{'client_id':'1'}); 
      // replacing '@client_id' from factory with 1. I also tried with quoteless 1.
    }
 ]);

最后，我有一个html视图，我尝试使用我应该使用$scope.thing进入<div ng-repeat'thing in things'>{{thing.ref}}</div>的数据。

通过阅读其他帖子，我确信向工厂添加isArray : false可以解决问题，因为它已经在另一家工厂修复了它。

有什么想法吗？

修改：感谢您的回复。我改变了我的工厂代码：

.factory('Things', ['$resource', function($resource) {

        return $resource(

            'api_url/:client_id',
            {client_id: '@client_id'}, // getting some data from an ID
            {'query' : {
                            method : 'GET', // ofc, it's a get request in the API
                            isArray : true //
                        }
            }

它修正了错误。现在，我处理了我的$scope内容的另一个问题，该内容未定义并发送$promise : Promise, $resolved : Resolved。我阅读了$resource doc以了解它的含义，但我仍然不知道如何使它工作。

正如doldt之前所说，你实际上是在期待一个数组。

您的回复是一系列对象。

您可以将isArray更改为true，或者更改服务器上的响应以返回对象。

更改后，您可以通过这种方式在控制器上使用您的资源（为$资源提供回调，因为您现在处理的是promises）：

$things.query( {}, { 'client_id' : '1' }, function( response ){
    $scope.thing = response;
});

我认为您使用 isArray 标记做错了。如果您要发送数组，则必须 true 。

试试吧......

// Code goes here

var myApp = angular.module('myApp', ['ngResource']);

myApp.factory('Things', ['$resource',
  function($resource) {

    return $resource(

      'data/sample.json'
      //, {
      //  client_id: '@client_id'
      //}, // getting some data from an ID
      //{
      //  'query': {
      //    method: 'GET', // ofc, it's a get request in the API
      //    isArray: true // to be sure to get an object and not an array
      //  }
      //})
    )
  }
]);

myApp.controller('myCtrl', function($scope, Things) {

  Things.query({}, {
    'client_id': '1'
  }).$promise.then(function(data) {
    $scope.thing = data;
    console.log($scope.thing);
  })
});
