概述
Hacker News 通过跟我们 Firebase的合作，使得Hacker
News中的信息能够实时的公布给用户。你可以轻松的使用 Android, iOS 和
通过 web 访问Firebase提供的数据。从服务器端当然也可以。我们甚至还支持 REST 协议。
如果你能使用众多的 Firebase 客户端程序库 中的某个接口，那就应该优先使用它们。这些程序库能够高效的处理网络连接，在有事件发生时可以及时的通知你。你应该研究一下它们。
如果你发现了任何的bug，请邮件给我们 [email protected] 。
Hacker News API中的URI和版本
这些API都由https://hacker-news.firebaseio.com提供。
我们努力在不断的改进它，将来将会允许使用OAuth认证来访问每个用户的私人数据。这些API中的修改并不一定会向后兼容，所以，我们将API以版本号形式发布。我们的第一版的地址是 https://hacker-news.firebaseio.com/v0/，下面是对API的结构和用法的描述。
单个条目信息
故事，评论，招聘，问答，以及投票都叫做条目。它们有各自唯一的ID，是不相互重复的整数形式，接口地址是： https://hacker-news.firebaseio.com/v0/item/.
所有的条目都共有下面的属性：
| 属性 | 描述 |
|---|---|
| id | The item’s unique id. Required. |
| deleted |
true ifthe item is deleted. |
| type | The type of item. One of “job”, “story”, “comment”, “poll”, or “pollopt”. |
| by | The username of the item’s author. |
| time |
Creation date of the item, in Unix Time. |
| text | The comment, Ask HN, or poll text. HTML. |

实时数据
Firebase最酷的地方是支持实时数据更新通知。你可以订阅条目信息，这时你可以观察它们在首页的名次，那些新条目出现，或新的用户信息更新。
