python pycurl 获取最终 url 重定向

Question

我需要访问网站 whit pycurl，跟随重定向，并打印最终 url，我写了这个 python 代码:

c = pycurl.Curl()
c.setopt(c.URL, 'http://localhost/redirect.php')
c.setopt(c.HTTPPOST, values)
c.setopt(c.WRITEFUNCTION, buf_pagina.write)
c.setopt(c.HEADERFUNCTION, buf_header.write)
c.setopt(c.CONNECTTIMEOUT, 30)
c.setopt(c.AUTOREFERER,1)
c.setopt(c.FOLLOWLOCATION, 1)
c.setopt(c.COOKIEFILE, '')
c.setopt(c.TIMEOUT, 30)
c.setopt(c.USERAGENT, '')
c.perform()

我需要打印最终网址，我该怎么做？谢谢。

解决方案是这样的:url_effective = c.getinfo(c.EFFECTIVE_URL)

这是我在评论中链接的 PHP 脚本的改编版:

import pycurl
import sys
import StringIO

o = StringIO.StringIO()
h = StringIO.StringIO()

c = pycurl.Curl()
c.setopt(c.URL, 'http://stackoverflow.com/questions/21444891')
# c.setopt(c.HTTPPOST, values)
c.setopt(c.WRITEFUNCTION, o.write)
c.setopt(c.HEADERFUNCTION, h.write)
c.setopt(c.CONNECTTIMEOUT, 30)
c.setopt(c.AUTOREFERER,1)
c.setopt(c.FOLLOWLOCATION, 1)
c.setopt(c.COOKIEFILE, '')
c.setopt(c.TIMEOUT, 30)
c.setopt(c.USERAGENT, '')
c.perform()

h.seek(0)

location = ""

for l in h:
    if "Location" in l:
        location = l.split(": ")[-1]

print location

不过，如本示例所示，您可能并不总是拥有完整的 URI，只有 URI 的路径部分(但如果是这种情况，则很容易将 fqdn 添加回来)
