    api.add_resource(Create, '/test')
    if __name__ == "__main__":
        app.run(port=5001, host="0.0.0.0", use_reloader=True)

我在下面的代码中调用了下面的 app1.py 创建了 waitress_server.py。只需执行 app1.py 就可以正常工作，但是当与女服务员一起尝试时，我看到通过邮递员的 HTTP 帖子被接收为 NULL。

我正在尝试使用女服务员进行生产设置。

from waitress import serve
import app1
serve(app1.app, host='0.0.0.0', port=5001)

当我拨打邮递员电话时，我看到响应为空。如果我做得对，请帮助我。

如果没有给定错误，您忘记返回响应。

具体这部分：

if __name__ == "__main__":
    dacl.AddAccessAllowedAce(win32security.      ACL_REVISION,win32con.GENERIC_READ, groupr) #os.makedirs(path)

缺少退货声明。postman 调用返回None是因为函数None默认返回。

您需要Response在上述代码之后添加 a 并在所有后备之后返回它。

PS：感谢您添加代码
