基本代码：

import praw
r = praw.Reddit(user_agent='Getting the data!!')
r.login("username","password",disable_warning=True)
results=r.search('whatever', subreddit=None, sort=None, syntax=None, period=None)
for x in results:
    print x

我希望编写一个代码来获取所有提交及其相关的评论。提交应受搜索查询和时间段的限制。

我面临的问题是：

一个。我不明白如何在上面指定时间段，文档往往很差

湾。我不知道结果是否受到限制。上面的代码产生：

我非常怀疑肯定不止这些。如果是，我怎样才能得到它们。如果请求被限制在一个时间窗口内。是否有一些解决方法可以让您睡觉然后获得更多？

C。我不知道它是否是像 twitter 这样的限制，而不是访问历史数据。尽管时期论点相反。还是不确定。

d.它返回一个生成器。我如何才能访问完整的提交文本和相关评论的文本。

对不起，如果它看起来有点间接，但是在线示例的缺乏和缺乏适当的文档导致面临这些问题。

A：它正在寻找类似“3 个月前”的内容。（您可以从API 文档中看到一些信息。它必须是one of (hour, day, week, month, year, all).

B：它有一个限制，它最多会返回大约 1000 个结果。可能有办法解决这个问题，但我不确定它们是什么，或者它们有多容易。

C：我猜是B的答案。

D：您正在寻找提交的属性，您可以通过属性访问这些属性（例如 object.attribute）。您可以在此页面上查看提交的完整属性列表。

因此，如果您想访问带有链接的自身文本，则必须执行以下操作：

for x in results:
    print x.selftext

但是，如果您想获得评论，这些评论不是对象的一部分。您需要获取提交 ID，然后查询提交本身以获取评论。

除非在搜索参数中指定了另一个数字，否则默认限制为 25。

因此，如果您想要更多结果，例如 100 个结果：

results=r.search('whatever', subreddit=None, sort=None, syntax=None, period=None, **limit=100**)

评论老问题：因为它可能会帮助其他人在未来寻找这个。
