我正在尝试创建一个与本地代码库（客户端部分）通信的扭曲守护进程（服务器部分）。基本上，客户端应该使用 AMP 调用远程（）到守护程序以开始一些处理（更新数据库）一些方法。在服务器上完成每个方法的处理后，我需要服务器调用远程（）到我的客户端，以便用户知道服务器的进度。
我已经能够从客户端调用服务器并获得响应，但我无法让服务器向客户端发送响应。
我搜索了一个解决方案，但找不到任何使用 AMP 进行双向通信的示例代码——它始终是客户端调用服务器。
我试图让客户端调用服务器以开始处理（ServerStart AMP 命令），然后让服务器将多个调用发送回客户端以提供处理更新（MessageClient AMP 命令）。
任何帮助将不胜感激。一个超级简单的示例展示了如何从客户端调用服务器，然后让服务器将两个调用传回给客户端，这将是非常棒的！
