如何在Python的HTTP标头中设置和检索Cookie？

您应该将cookielib模块与urllib一起使用。

它将在请求之间存储cookie，您可以将它们加载/保存在磁盘上。这是一个例子：

import cookielibimport urllib2cookies = cookielib.LWPcookieJar()handlers = [    urllib2.HTTPHandler(),    urllib2.HTTPSHandler(),    urllib2.HTTPcookieProcessor(cookies)    ]opener = urllib2.build_opener(*handlers)def fetch(uri):    req = urllib2.Request(uri)    return opener.open(req)def dump():    for cookie in cookies:        print cookie.name, cookie.valueuri = 'http://www.google.com/'res = fetch(uri)dump()res = fetch(uri)dump()# save cookies to disk. you can load them with cookies.load() as well.cookies.save('mycookies.txt')

请注意，请求之间的
