手动和自动获取cookie方式

# 1.selenium手动登录并获取cookie
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.common.exceptions import NoSuchElementException
import time
import json

driver = webdriver.Chrome()
driver.get("https://passport.bilibili.com/login")
flag = True
print("等待登录...")
while flag:
    try:
        driver.find_element(By.XPATH,
                             "//div[@class='user-con signin']|//ul[@class='right-entry']"
                             "//a[@class='header-entry-avatar']")
        flag = False
    except NoSuchElementException as e:
        time.sleep(3)
print("已登录，现在为您保存cookie...")
with open('cookie.txt', 'w', encoding='u8') as f:
    json.dump(driver.get_cookies(), f)
driver.close()
print("cookie保存完成，游览器已自动退出...")

# 2.那么后续selenium程序启动时如何直接使用该cookie而不需再次登录呢？
driver = webdriver.Chrome()
with open('cookie.txt', 'r', encoding='u8') as f:
    cookies = json.load(f)
driver.get("https://www.bilibili.com/")
for cookie in cookies:
    driver.add_cookie(cookie)
driver.get("https://www.bilibili.com/")
# 上面的流程就是先访问要加载cookie的网站，再迅速向其添加cookie，再重新访问一遍该网站加载的cookie即可生效
