不使用数组Angularjs $资源从REST API返回 [英] Angularjs $resource not working with an array returned from a REST API
问题描述
我努力学习angularjs，并试图数据绑定到一个数组从REST API返回击中块。我有一个简单的API湛蓝人返回对象的数组。服务URL是 http://testv1.cloudapp.net/test.svc/persons 。
I am trying to learn angularjs, and have hit a block in trying to databind to an array returned from a Rest API. I have a simple azure api returning an array of person objects. Service url is http://testv1.cloudapp.net/test.svc/persons.
我的控制器code如下：
My controller code looks like:
angular.module("ToDoApp", ["ngResource"]);
function TodoCtrl($scope, $resource) {
$scope.svc = $resource('http://testv1.cloudapp.net/test.svc/persons', {
callback: 'JSON_CALLBACK'
}, {
get: {
method: 'JSONP',
isArray: true
}
});
$scope.items = $scope.svc.get();
$scope.msg = "Hello World";
}
我的HTML如下：
My html looks like:
<html>
<head></head>
<body>
<div ng-app="ToDoApp">
<div ng-controller="TodoCtrl">
<h1>{{msg}}</h1>
<table class="table table-striped table-condensed table-hover">
<thead>
<th>Email</th>
<th>First Name</th>
<th>Last Name</th>
</thead>
<tbody>
<tr ng-repeat="item in items">
<td>{{item.Email}}</td>
<td>{{item.FirstName}}</td>
<td>{{item.LastName}}</td>
</tr>
</tbody>
</table>
</div>
</div>
</body>
</html>
问：上面HTML表不显示任何数据。我可以看到呼叫在Firebug的API，并且还可以看到从API JSON响应。我在做什么错误导致该数据绑定到REST API不工作？
Question: The table in above html is not displaying any data. I can see the call to the api in Firebug, and can also see the JSON response from the api. What am I doing incorrectly that is causing the databinding to the REST api not work?

推荐答案
为了处理与资源$阵列的服务，它的建议您使用查询方法。正如你可以看到下面的查询方法是建立在处理数组。
In order to handle arrays with the $resource service, it's suggested that you use the query method. As you can see below, the query method is built to handle arrays.
{ 'get': {method:'GET'},
'save': {method:'POST'},
'query': {method:'GET', isArray:true},
'remove': {method:'DELETE'},
'delete': {method:'DELETE'} };
您应该以这个数组返回到你的范围内使用的code是
The code you should use in order to return this array to your scope is
angular.module("ToDoApp", ["ngResource"]);
function TodoCtrl($scope, $resource) {
var svc = $resource('http://testv1.cloudapp.net/test.svc/persons');
$scope.items = svc.query();
$scope.msg = "Hello World";
}
这假定您的REST API工作，并会返回一个数组。
This assumes that your REST API is working and will return an array.
