    # 执行命令
    command = "smidump -f python -k SANGFOR-GENERAL-MIB.mib > output.py"

    stdin, stdout, stderr = client.exec_command(command)

    # 获取命令执行结果
    output = stdout.read().decode("utf-8")
    error = stderr.read().decode("utf-8")

    if error:
        print(f"命令执行失败：{error}")
    else:
        # 处理output，比如保存为文件
        with open("output.py", "w") as f:

finally:
