javascript - 使用 Angular.js 解析 JSON 中的嵌套对象数组

Question

我是 Angular.js 新手。在这里，我正在开发一个购物车，其中必须显示产品的图像、名称和成本。我有多个租户，每个租户都有数组 listOfBinaries，其中包含 listOfMerchandise。我的问题是我必须显示租户的姓名、listOfBinary 的图像和 listOfMerchandise 的成本。我解析了 JSON，如下所示，但在运行时我得到了空页面。谁能帮帮我吗。这是我对 REST URL 进行 AJAX 调用后得到的 JSON:

{
"_links": {
    "search": {
        "href": "http://localhost:8080/sportsrest/tenants/search"
    }
},
"_embedded": {
    "tenants": [
        {
            "name": "tenant1",
            "domainName": "gaming.com",

                ]
            }
        }
    ]
}

}

我的directives.js 文件:当我进行此 Ajax 调用时，我得到的结果高于 JSON

 myAppDirectives.
  controller('items_display', function ($scope,$http) {
 $http({ method: 'GET', url: 'http://localhost:8080/sportsrest/tenants/' }).success(function (data) {
 $scope.carts=data; 
 }).
 error(function (data) {
     alert("error" + data);
     console.log(data);
 });
 });

我的 HTML 页面:

<!DOCTYPE html>
 < html ng-app="myApp">
<head>
    <script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.2.26/angular.min.js"></script>

   </head>
   <body>
    <div ng-app="myApp" >
    <div  ng-controller="items_display">
    <div  ng-repeat="item in carts._embedded.tenants">
    <div type="text" class="item_name" value={{item.name}}  > 
    <div  ng-repeat="item in carts._embedded.tenants.listOfBinary">
     <img  class="shop_img" ng-src="{{item.fileLocation}}"  ng-style="{'width':'100px', 'height':'100px'}" /> 
     <div  ng-repeat="item in carts._embedded.tenants.listOfBinary.listOfMerchandise">
      <div type="text" class="item_cost" value={{item.rate}}  > 
    </div>  
      </br>
     </div>
    </div>
    </div>
</body>

谁能帮忙使用 Angular.js 在 html 页面上显示产品详细信息。

提前致谢
