javascript - AngularJS - Restheart API (MongoDB) - 解析 JSON 结果

Question

我正在使用 RestHeart 公开来自 MongoBD 的 CRUD 操作。并尝试从 AngularJS 调用 Rest API 并获取如下 JSON 字符串所示的 JSON 结果。但我只对存储在 MongoDB 中的姓名、年龄和城市字段感兴趣。

我不知道如何获取这些值。

Javascript代码:-

crudApp.controller('listController', function($scope, $http, $location,
    crudService) {

$http.get('http://localhost:8081/jaydb/employees').success(
        function(response) {
            console.log('response : ' +JSON.stringify(response));
            $scope.employees = response;
        });

})

REST API 的 JSON 结果

Answer 1

RESTHeart使用HAL格式，看看resource representation section有关更多信息，请参阅 Restheart 文档。

总之，您的请求是对集合资源的 GET:响应包括第一级集合自身的属性及其作为嵌入资源的文档。

您可以通过包含数组 rh:doc 的 _embedded 属性访问集合的文档；该数组的元素是您的文档。

另请注意，文档是分页的:默认情况下，RESTHeart 返回前(最多)1000 个文档。您可以通过 page 和 pagesize 查询参数控制分页。

如果您还传递 count 查询参数，您将获得 _size 和 _total_pages 属性。

_links 参数包括指向下一页和上一页的下一页 以及最终的上一页 链接。
