selenium使用cookie登录百度网页

1.首先我们先来了解下cookie的几种方法

get_cookies()：获取所有cookie值

get_cookie(name)：根据cookie的name值获取对应的value值

get_all_cookies：删除所有cookie

get_delete_cookie(name)：根据name值删除对应的value值

add_cookie(dict)：添加cookie值，类型为字典

2.实例

1）进入百度登录页面，等待30s，手动输入账号和密码点击登录

option = webdriver.ChromeOptions()
option.add_experimental_option("excludeSwitches", ["enable-automation"])
driver = webdriver.Chrome(options=option)
driver.get("https://www.baidu.com/")
time.sleep(30)　　

2）获取所有cookies值，并存储在本地json文件中

cookie_all = driver.get_cookies()
with open("./file.json", mode="w") as f:
    json.dump(cookie_all, f)

3）读取本地cookie值并添加

with open("./file.json", mode="r") as b:
    list_cooke = json.load(b)  # 读取cookie
    for cook in list_cooke:
        driver.add_cookie(cook)  # for遍历添加cookie
driver.refresh()  # 刷新页面

3.完整代码

import json
import time

from selenium import webdriver

def option():
    options = webdriver.ChromeOptions()
    options.add_experimental_option("excludeSwitches", ["enable-automation"])
    driver = webdriver.Chrome(options=options)
    driver.get("https://www.baidu.com/")
    time.sleep(30)
    return driver

# 获取cookie值
cookie_all = option().get_cookies()
with open("./file.json", mode="w") as f:
    json.dump(cookie_all, f)

# 读取cookie值
with open("./file.json", mode="r") as b:
    list_cooke = json.load(b)  # 读取cookie
    for cook in list_cooke:
        option().add_cookie(cook)  # for遍历添加cookie
option().refresh()  # 刷新页面
