Python获取Cookie的方法总结

import requests

# 发送GET请求
response = requests.get("https://example.com")

# 获取服务器返回的Cookie
cookies = response.cookies

# 打印Cookie
for cookie in cookies:
    print(f"Name: {cookie.name}, Value: {cookie.value}")

from flask import Flask, request

app = Flask(__name)

@app.route('/')
def get_cookie():
    # 获取客户端发送的Cookie
    cookie_value = request.cookies.get('my_cookie')
    return f"Cookie Value: {cookie_value}"

if __name__ == '__main__':
    app.run()

import http.cookiejar
import urllib.request

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

# 创建HTTPCookieProcessor
cookie_processor = urllib.request.HTTPCookieProcessor(cookie_jar)

# 创建Opener
opener = urllib.request.build_opener(cookie_processor)

# 发送GET请求
response = opener.open("https://example.com")

# 获取服务器返回的Cookie
for cookie in cookie_jar:
    print(f"Name: {cookie.name}, Value: {cookie.value}")

import requests

# 构建登录请求
login_data = {
    'username': 'your_username',
    'password': 'your_password'
}

# 发送POST请求以登录
login_response = requests.post("https://example.com/login", data=login_data)

# 获取登录后的Cookie
auth_cookies = login_response.cookies

# 使用登录后的Cookie进行后续请求
profile_response = requests.get("https://example.com/profile", cookies=auth_cookies)

# 输出用户信息
print(profile_response.text)

import http.cookiejar
import urllib.request

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

# 创建HTTPCookieProcessor
cookie_processor = urllib.request.HTTPCookieProcessor(cookie_jar)

# 创建Opener
opener = urllib.request.build_opener(cookie_processor)

# 发送GET请求
response = opener.open("https://example.com")

# 获取服务器返回的Cookie
for cookie in cookie_jar:
    print(f"Name: {cookie.name}, Value: {cookie.value}")

# 删除过期的Cookie
cookie_jar.clear_expired_cookies()

# 保存Cookie到文件
cookie_file = "my_cookies.txt"
cookie_jar.save(cookie_file)

# 从文件加载Cookie
loaded_cookie_jar = http.cookiejar.MozillaCookieJar(cookie_file)
loaded_cookie_jar

.load()

# 使用加载的Cookie进行请求
loaded_opener = urllib.request.build_opener(urllib.request.HTTPCookieProcessor(loaded_cookie_jar))
loaded_response = loaded_opener.open("https://example.com")

# 输出加载的Cookie
for cookie in loaded_cookie_jar:
    print(f"Name: {cookie.name}, Value: {cookie.value}")
