如何在Python中保存每个会话的Cookie？

import http.cookiejar

cookie_jar = http.cookiejar.CookieJar()

cookie_handler = urllib.request.HTTPCookieProcessor(cookie_jar)

opener = urllib.request.build_opener(cookie_handler)

response = opener.open(url)

cookie_jar.save("cookies.txt", ignore_discard=True, ignore_expires=True)

import http.cookiejar
import urllib.request

# 创建一个CookieJar对象
cookie_jar = http.cookiejar.CookieJar()

# 创建一个HTTPCookieProcessor对象，并将CookieJar对象传递给它
cookie_handler = urllib.request.HTTPCookieProcessor(cookie_jar)

# 创建一个OpenerDirector对象，并将HTTPCookieProcessor对象传递给它
opener = urllib.request.build_opener(cookie_handler)

# 使用OpenerDirector对象发送HTTP请求，并保存Cookie
response = opener.open(url)

# 将Cookie保存到文件中
cookie_jar.save("cookies.txt", ignore_discard=True, ignore_expires=True)
