从维基百科中提取随机页面时，脚本总是得到302响应

问题描述

我可以从维基百科中提取任何页面

I can pull a any page from wikipedia with

import httplib
conn = httplib.HTTPConnection("en.wikipedia.org")
conn.debuglevel = 1
conn.request("GET","/wiki/Normal_Distribution",headers={'User-Agent':'Python httplib'})
r1 = conn.getresponse()
r1.read()

正常情况回复将是

reply: 'HTTP/1.0 200 OK\r\n'
header: Date: Sun, 03 Apr 2011 23:49:36 GMT
header: Server: Apache
header: Cache-Control: private, s-maxage=0, max-age=0, must-revalidate
header: Content-Language: en
header: Vary: Accept-Encoding,Cookie
header: Last-Modified: Sun, 03 Apr 2011 17:23:50 GMT

header: X-Cache: MISS from sq66.wikimedia.org
header: X-Cache-Lookup: MISS from sq66.wikimedia.org:80
header: Connection: close

但如果我尝试使用/ wiki / Special拉随机页面：随机我得到302响应并且空页

But if I try to pull a random page with /wiki/Special:Random I get a 302 response and an empty page

reply: 'HTTP/1.0 302 Moved Temporarily\r\n'

如何获得非空的随机页面？

How do I get a non-empty random page?

推荐答案

302是重定向。它告诉你去哪一行：

The 302 is a redirect. It's telling you where to go in the following line:

header: Location: http://en.wikipedia.org/wiki/tuticorin_port_trust 

您只需按照重定向即可。

You just need to follow the redirect.
