Selenium?有很多功能，?但其核心是?web?瀏覽器自動(dòng)化的一個(gè)工具集，它允許用戶模擬終端用戶執(zhí)行的常見活動(dòng)；將文本輸入到字段中，選擇下拉值和復(fù)選框，并單擊文檔中的鏈接。?它還提供許多其他控件，比如鼠標(biāo)移動(dòng)、任意?JavaScript?執(zhí)行等等。
雖然?Selenium?主要用于網(wǎng)站的前端測(cè)試，但其核心是瀏覽器用戶代理庫(kù)。本次來(lái)說(shuō)說(shuō)，Python使用Selenium調(diào)用Chrome瀏覽器并通過(guò)HTTP代理進(jìn)行自動(dòng)化測(cè)試：
白名單模式代碼示例：
```python
from selenium import webdriver
from selenium.webdriver.chrome.service import Service
targetURL = "http://myip.ipip.net" #訪問(wèn)的目標(biāo)站點(diǎn)
proxyAddr = "您的代理IP:端口號(hào)"
if __name__ == '__main__':
browser_location = r".\Chrome\chrome.exe" #指定瀏覽器路徑位置
driver_location = r".\Chrome\chromedriver.exe" #指定Driver路徑位置
option = webdriver.ChromeOptions()
option.binary_location = browser_location #設(shè)置瀏覽器位置
option.add_argument("--start-maximized") #窗口最大化運(yùn)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)
```運(yùn)行結(jié)果：
賬密模式代碼如下：
