温馨提示：

1.  此代码样例分别为基于"终端IP"授权和"用户名+密码"授权方式使用Selenium+Chrome认证代理IP

2.  运行环境为python2/3 + selenium + Chrome + Chromedriver + Windows/Linux/macOS

3.  注意chromedriver版本要和Chrome版本对应

4.  样例中代理IP需更换为自己通过站大爷API提取链接获取到的代理IP

5.  ${chromedriver_path}：您本机chromedriver驱动存放路径，如："C:\chromedriver.exe"

6.  selenium不是python原生库，需要安装才能使用：pip install selenium；4.6版本开始，无需手动下载driver

7.  样例中的"实例ID"和"密码"显示在站大爷控制台的"实例管理"里。

"终端IP"授权

from selenium import webdriver
import time

options = webdriver.ChromeOptions()
options.add_argument('--proxy-server=http://${168.168.168.168:88888}')
# ${chromedriver_path}: chromedriver驱动存放路径
driver=webdriver.Chrome(executable_path="${chromedriver_path}", options=options)
driver.get("https://example.com")

# 获取页面内容
print(driver.page_source)

# 延迟3秒后关闭当前窗口如果是最后一个窗口则退出
time.sleep(3)
driver.close()

"用户名+密码"授权

from selenium import webdriver
import string
import zipfile
