帮助将使用 httlib2 的代码转换为使用 urllib2

我想做什么？

访问站点，检索 cookie，通过发送 cookie 信息访问下一页。这一切都有效，但 httplib2 给我在一个站点上使用袜子代理带来了太多问题。

http = httplib2.Http()
main_url = 'http://mywebsite.com/get.aspx?id='+ id +'&rows=25'
response, content = http.request(main_url, 'GET', headers=headers)
main_cookie = response['set-cookie']
referer = 'http://google.com'
headers = {'Content-type': 'application/x-www-form-urlencoded', 'Cookie': main_cookie, 'User-Agent' : USER_AGENT, 'Referer' : referer}

如何使用 urllib2 做同样的事情（cookie 检索，传递到同一站点上的下一页）？

谢谢。

What am I trying to do?

Visit a site, retrieve cookie, visit the next page by sending in the cookie info. It all works but httplib2 is giving me one too many problems with socks proxy on one site.

http = httplib2.Http()
main_url = 'http://mywebsite.com/get.aspx?id='+ id +'&rows=25'
response, content = http.request(main_url, 'GET', headers=headers)
main_cookie = response['set-cookie']
referer = 'http://google.com'
headers = {'Content-type': 'application/x-www-form-urlencoded', 'Cookie': main_cookie, 'User-Agent' : USER_AGENT, 'Referer' : referer}

How to do the same exact thing using urllib2 (cookie retrieving, passing to the next page on the same site)?

Thank you.

使用cookielib，它会自动处理所有与cookie相关的工作就像网络浏览器一样。

例子：

import urllib2
import cookielib

cookie_jar = cookielib.LWPCookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cookie_jar))

#Get the first page with the cookie, installing it in the cookie jar automatically
opener.open("http://yoursite.com/set-cookie")

#Get the second page, passing on the cookie in the cookiejar.
opener.open("http://yoursite.com/other")

#Alternatively, you can also install this opener as the default urllib2 opener:
urllib2.install_opener(opener)
#Now all urllib2 requests will use cookies:
urllib2.urlopen("http://yoursite.com/other")

Use cookielib, it'll handle all the cookie related work as automatically as a web browser would.

Example:

import urllib2
import cookielib

cookie_jar = cookielib.LWPCookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cookie_jar))

#Get the first page with the cookie, installing it in the cookie jar automatically
opener.open("http://yoursite.com/set-cookie")

#Get the second page, passing on the cookie in the cookiejar.
opener.open("http://yoursite.com/other")

#Alternatively, you can also install this opener as the default urllib2 opener:
urllib2.install_opener(opener)
#Now all urllib2 requests will use cookies:
urllib2.urlopen("http://yoursite.com/other")
