Selenium 有很多功能， 但其核心是 web 浏览器自动化的一个工具集，它允许用户模拟终端用户执行的常见活动；将文本输入到字段中，选择下拉值和复选框，并单击文档中的链接。 它还提供许多其他控件，比如鼠标移动、任意 JavaScript 执行等等。
虽然 Selenium 主要用于网站的前端测试，但其核心是浏览器用户代理库。本次来说说，Python使用Selenium调用Chrome浏览器并通过HTTP代理进行自动化测试：
白名单模式代码示例：
```python
from selenium import webdriver
from selenium.webdriver.chrome.service import Service
targetURL = "http://myip.ipip.net" #访问的目标站点
proxyAddr = "您的代理IP:端口号"
if __name__ == '__main__':
browser_location = r".\Chrome\chrome.exe" #指定浏览器路径位置
driver_location = r".\Chrome\chromedriver.exe" #指定Driver路径位置
option = webdriver.ChromeOptions()
option.binary_location = browser_location #设置浏览器位置
option.add_argument("--start-maximized") #窗口最大化运行
option.add_argument('--proxy-server=%(server)s' % {"server": proxyAddr})
driver = webdriver.Chrome(service=Service(driver_location), options=option)
driver.get(targetURL)
print(driver.page_source)
```运行结果：
账密模式代码如下：
from selenium import webdriver
from selenium.webdriver.chrome.service import Service
import string
import zipfile
targetURL = "http://d.qg.net/ip" #访问的目标站点
proxyHost = "您的代理IP"
proxyPort = "端口号"
authKey = "请改成您的Key"
password = "请改成您的AuthPwd"
# 账密模式
def create_proxy_auth_extension(proxy_host, proxy_port, proxy_username, proxy_password, scheme='http', plugin_path=None):
if plugin_path is None:
plugin_path = r'./{}_{}_qgnet_proxyauth_plugin.zip'.format(proxy_username, proxy_password)
manifest_json = """

background_js = string.Template(

};
chrome.proxy.settings.set({value: config, scope: "regular"}, function() {});
function callbackFn(details) {
return {
authCredentials: {
username: "${username}",
password: "${password}"
}
};
}
chrome.webRequest.onAuthRequired.addListener(
callbackFn,
{urls: [""]},
['blocking']
);
"""
).substitute(
host=proxy_host,
port=proxy_port,
username=proxy_username,
password=proxy_password,
scheme=scheme,
)
with zipfile.ZipFile(plugin_path, 'w') as zp:
zp.writestr("manifest.json", manifest_json)
zp.writestr("background.js", background_js)
return plugin_path
if __name__ == '__main__':
# browser_location = r"C:\Users\Administrator\Desktop\Chrome\chrome.exe" # 指定浏览器路径位置
driver_location = r"C:\Users\Administrator\Desktop\Chrome\chromedriver.exe" # 指定Driver路径位置
proxy_auth_plugin_path = create_proxy_auth_extension(
proxy_host=proxyHost,
proxy_port=proxyPort,
proxy_username=authKey,
proxy_password=password)
option = webdriver.ChromeOptions()
# option.binary_location = browser_location #设置浏览器位置
option.add_argument("--start-maximized") #窗口最大化运行
option.add_extension(proxy_auth_plugin_path) #添加proxy插件
driver = webdriver.Chrome(service=Service(driver_location), options=option)
driver.get(targetURL)
print(driver.page_source)
