小白学爬虫-设置Selenium+Chrome代理

微博登录限制了错误次数···加上Cookie大批账号被封需要从Cookie池中 剔除被封的账号··· 需要使用代理··· 无赖百度了大半天都是特么的啥玩意儿???结果换成了 Google手到擒来 分分钟解决(那么问题来了?百度除了卖假药还会干啥?) Selenium+Chrome认证代理不能通过options处理。只能换个方法使用扩展解决 原文地址:https://stackoverflow.com/questions/29983106/how-can-i-set-proxy-with-authentication-in-selenium-chrome-web-driver-using-pyth#answer-30953780 (Stack Overflow 这是个好地方啊) 走你!

from selenium import webdriver
from common.pubilc import create_proxyauth_extension

proxyauth_plugin_path = create_proxyauth_extension(
proxy_host="XXXXX.com",
proxy_port=9020,
proxy_username="XXXXXXX",

# co.add_argument("--start-maximized")
co.add_extension(proxyauth_plugin_path)


driver = webdriver.Chrome(executable_path="C:\chromedriver.exe", chrome_options=co)
driver.get("http://ip138.com/")
print(driver.page_source)

无认证代理:

options = webdriver.ChromeOptions()
options.add_argument('--proxy-server=http://ip:port')
driver = webdriver.Chrome(executable_path="C:\chromedriver.exe", chrome_options=0ptions)
driver.get("http://ip138.com/")
print(driver.page_source)
以上完毕 So Easy
