首先手工登录一次获取cookies，然后进行数据保存

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.common.by import By
import time
import json# 创建Chrome浏览器对象
chrome_opt = webdriver.ChromeOptions()
# 开启无界面模式
#chrome_opt.add_argument('--headless')
# 禁用gpu
chrome_opt.add_argument('--disable-gpu')
service = Service('D:/网页数据爬取/selenium练习/chromedriver.exe')
# 创建Chrome浏览器实例
browser = webdriver.Chrome(service=service,options=chrome_opt)#记得写完整的url 包括http和https
browser.get('https://space.bilibili.com/')# 等待页面加载完成
browser.implicitly_wait(10)
#程序打开网页后20秒内手动登陆账户
time.sleep(10)browser.find_element(By.CSS_SELECTOR,'input[type="text"]').send_keys('用户名')
browser.find_element(By.CSS_SELECTOR,'input[type="password"]').send_keys('密码')
#程序打开网页后30秒内手动登陆账户
time.sleep(30)with open('cookies.txt','w') as cookief:#将cookies保存为json格式cookief.write(json.dumps(browser.get_cookies()))
browser.close()

然后使用现有cookies登录用户，进行网页访问，获取清晰视频

# 创建Chrome浏览器实例
browser = webdriver.Chrome(service=service,options=chrome_opt)#记得写完整的url 包括http和https
browser.get('https://space.bilibili.com/')
#首先清除由于浏览器打开已有的cookies
browser.delete_all_cookies()with open('cookies.txt','r') as cookief:#使用json读取cookies 注意读取的是文件 所以用load而不是loadscookieslist = json.load(cookief)# 方法1 将expiry类型变为intfor cookie in cookieslist:#并不是所有cookie都含有expiry 所以要用dict的get方法来获取if isinstance(cookie.get('expiry'), float):cookie['expiry'] = int(cookie['expiry'])browser.add_cookie(cookie)#记得写完整的url 包括http和https
