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 api@ycombinator.com 。

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
idThe item’s unique id. Required.
deletedtrue if the item is deleted.
typeThe type of item. One of “job”, “story”, “comment”, “poll”, or “pollopt”.
byThe username of the item’s author.
timeCreation date of the item, in Unix Time.
textThe comment, Ask HN, or poll text. HTML.
deadtrue if the item is dead.
parentThe item’s parent. For comments, either another comment or the relevant story. For pollopts, the relevant poll.
kidsThe ids of the item’s comments, in ranked display order.
urlThe URL of the story.
scoreThe story’s score, or the votes for a pollopt.
titleThe title of the story or poll.
partsA list of related pollopts, in display order.

举例说明，一个故事的数据结构是这样的：: https://hacker-news.firebaseio.com/v0/item/8863.json?print=pretty

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。
