Hacker News API中的URI和版本

API都由https://hacker-news.firebaseio.com提供。

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：

id	The item’s unique id. Required.
deleted	`true` if the item is deleted.
type	The type of item. One of “job”, “story”, “comment”, “poll”, or “pollopt”.

time	Creation date of the item, in Unix Time.
text	The comment, Ask HN, or poll text. HTML.
dead	`true` if the item is dead.

kids	The ids of the item’s comments, in ranked display order.
url	The URL of the story.
score	The story’s score, or the votes for a pollopt.
title	The title of the story or poll.
parts	A list of related pollopts, in display order.
