Openvpn无法通过基于用户的脚本发送cURL请求

import subprocess

    command = ['curl', url]
    result = subprocess.run(command, capture_output=True, text=True)
    if result.returncode == 0:
        return result.stdout
    else:
        return result.stderr

# 在连接建立时执行的脚本

    # 发送cURL请求示例
    response = send_curl_request('https://example.com/api')

# 在连接断开时执行的脚本
def client_disconnect():
    # 发送cURL请求示例
    response = send_curl_request('https://example.com/api')
    print(response)

# 在连接建立时执行client_connect函数
# 在连接断开时执行client_disconnect函数
