Demo for LMQ
我用golang写了客户端demo。golang客户端能够发布消息,但不能接收到订阅消息。用golang发布消息,PHP客户端能收到订阅,很神奇。
从这里 https://help.aliyun.com/document_detail/44866.html?spm=a2c4g.11186623.6.560.67b3672bnyEzG0 下载了C版本的sdk,然后在使用Imq-demo里面的C版本代码时,程序启动就报错!
用depends查看,发现运行时库需要vc140版本的,所以sdk是需要vs2015才可以使用?

使用这个类发送P2P消息通信 MQTTSendP2PMessage.class
重现步骤
1.启动MQTTSendP2PMessage连接mqtt
2.启动设备A
3.MQTTSendP2PMessage正常与设备A通信
4.断开MQTTSendP2PMessage服务所在电脑网络
5.隔5秒后重新接通网络
6.即打印如下错误,只能重启MQTTSendP2PMessage服务才能正常通信
