我是 python 新手，當我想運行以下簡單代碼時，出現錯誤：
from selenium import webdriver
browser = webdriver.Firefox()
browser.get("http://www.whatsmyip.org")
錯誤：

urllib3.exceptions.ProxySchemeUnknown: Proxy URL had no scheme, should start with http:// or https://
預先感謝您的指導。
uj5u.com熱心網友回復：
當您的客戶端代碼（您的測驗）嘗試向 WebDriver 服務發送命令時，會出現此錯誤。由于它是 REST（通過 http），Selenium 采用在環境變數中為相應協議定義的代理：
def _get_proxy_url(self):
if self._url.startswith('https://'):
return os.environ.get('https_proxy', os.environ.get('HTTPS_PROXY'))
elif self._url.startswith('http://'):
return os.environ.get('http_proxy', os.environ.get('HTTP_PROXY'))
看起來分配給這些變數之一（或兩者）的值不是正確的 URL。
解決方案是：
- 要么修復 URL
- 或切換
ignore_local_proxy_environment_variables中FirefoxOptions
