在Python中检索所有Cookie

Question

如何在不知道名称的情况下用 Python 读回所有 cookie？

Answer 1

不确定这是否是您正在寻找的内容，但这是一个简单的示例，您将 cookie 放入 cookiejar 中并读回它们：

from urllib2 import Request, build_opener, HTTPCookieProcessor, HTTPHandler
import cookielib

#Create a CookieJar object to hold the cookies
cj = cookielib.CookieJar()
#Create an opener to open pages using the http protocol and to process cookies.
opener = build_opener(HTTPCookieProcessor(cj), HTTPHandler())

#create a request object to be used to get the page.
req = Request("http://www.about.com")
f = opener.open(req)

#see the first few lines of the page
html = f.read()
print html[:50]

#Check out the cookies
print "the cookies are: "
for cookie in cj:
    print cookie

Answer 2

将

os.environ['HTTP_COOKIE']

放入数组中：

#!/usr/bin/env python

import os

 if 'HTTP_COOKIE' in os.environ:
  cookies = os.environ['HTTP_COOKIE']
  cookies = cookies.split('; ')
  handler = {}

  for cookie in cookies:
   cookie = cookie.split('=')
   handler[cookie[0]] = cookie[1]

Answer 3

这可能正是您正在寻找的。

Python 3.4

import requests

r = requests.get('http://www.about.com/')
c = r.cookies
i = c.items()

for name, value in i:
    print(name, value)

Answer 4

查看您获得的 HTTP 响应中的

Cookie:

标头，使用标准库中的模块

Cookie

解析其内容。

Answer 5

2024 / Python 3.11+ 的更新答案，使用 HTTPSConnection/HTTPResponse

from http.client import HTTPResponse

def get_response_cookies(http_response: HTTPResponse):
    cookie_list = http_response.headers.get_all("set-cookie")
    if cookie_list is None or len(cookie_list) == 0:
        return None
    cookies = {}
    for cookie_str in cookie_list:
        cookie_info = cookie_str.split("; ")
        [name, val] = cookie_info[0].split("=")
        cookies[name] = val
    return cookies

您只需在连接请求的 HttpResponse 结果上调用此函数即可：

from http.client import HTTPSConnection

connection = HTTPSConnection(host)
connection.request(method=req_method, url=path_url, body=body, headers=headers)
response = connection.getresponse()
cookies = get_response_cookies(response)
