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);
})
});[
