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:
```python
from selenium import webdriver
from selenium.webdriver.chrome.service import Service
targetURL = "" #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{BANNED}最佳大化运行
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:
from selenium.webdriver.chrome.service import Service
import string
import zipfile
targetURL = "" #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 = """
