无法从socket_.async_receive_from接收数据。 回答: 在云计算领域中,socket.async_receive_from是一个用于异步接收数据的函数。它通常用于网络通信中的数据接收操作。然而,如果无法从socket.async_receive_from接收数据,可能有以下几个可能的原因和解决方法: 网络连接问题:首先需要确保网络连接正常。可以通过检查网络配置...

继续进行的调试工作表明,回调方法中的ReceiveFromAsync调用始终返回false(表示它不会引发receive completed事件)。如果它从未引发事件,这将解释为什么不显示日志消息。 另一件令人不安的事情是,ReceiveFromAsync立即返回的事件参数包含刚刚处理的传入消息的尾随部分,即使我在调用ReceiveFromAsync之前为SetBuffer分配了新的Socket...
