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JSON结果，如下面的JSON字符串所示。但是我只对存储在MongoDB中的名称，年龄和城市字段感兴趣。
我不确定如何获得这些价值。
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

最佳答案
RESTHeart使用HAL格式，请参阅restheart文档的resource representation section以获取更多信息。
总而言之，您的请求是对集合资源的GET：响应包括集合在第一层的自身属性以及作为嵌入式资源的文档。
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返回第一个（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，则将获得_size和_total_pages属性。
_links参数包括指向下一页和上一页的下一个以及最终的上一个链接。
