多个返回键 json

Question

我有一个 joomla 站点 运行 k2 并通过在字符串末尾添加格式=json 从中提取信息：https://www.example.com/posts?format=json 输出如下所示：

{
site: {
      url: "https://www.example.com",
      name: "mySite"
      },
category: {
          id: "67",
          name: "Gauteng",
          alias: "gauteng",
          link: "/tna/provincial/gauteng.html",
          parent: "66",
          extraFieldsGroup: "0",
          image: null,
          ordering: "1",
        events: {
          K2CategoryDisplay: ""
        },
        chidlren: []
       },
items: [{ 
         id="1",
         title="The Title",
         body="body content here..."
        },
        { 
         id="2",
         title="The Title",
         body="body content here..."
        }
}

现在我正在为此创建服务，只想访问 "items"。

.factory('Posts', function($http) {

  var posts = [];

  return {
        getPosts: function(){
            return $http.get("https://www.example.com/posts?format=json").then(function(response){
                posts = response;
                return posts;
            });
        },
        getPost: function(index){
            return posts[index];
        }
    }

});

虽然它似乎没有用。有什么方法可以通过通话访问 "items" 吗？

Answer 1

你的 post 语法应该是 posts = response.data.items

return $http.get("https://www.example.com/posts?format=json").then(function(response){
    posts = response.data.items; //items here
    return posts;
});
