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

使用方法:

复制代码
 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",
    proxy_password="XXXXXXX" )
 
 
co = webdriver.ChromeOptions()
# 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) 
复制代码

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)
