订阅主题#出错

[cokll]

相同的代码一个可以订阅#主题一个不能订阅 是为什么
还有如何修改全局消息过期时间为10s

代码没有做任何更改 大概报错2-3分钟后就可以成功订阅

@cokll 能提供一下复现问题的简单的demo代码吗？

[cokll]

@werbenhu 客户端为esp32 库为AsyncMqttClient

订阅代码 mqtt_topic="car_wifi/#";

mqtt.log

[werbenhu]

通配符 + #这种只能在订阅的topic里面用，你是不是在publish的时候也用了这个带了通配符的topic了

[cokll]

@werbenhu 就是订阅 订阅完了才可以 publish啊 都没订阅怎么publish
大概报错等个1-2分钟 错误就消失了 就可以正常用
还有如果每20毫秒发送一次数据 发送一晚上后
mqtt服务器就不会再响应 ，必须重启服务器才可以继续接收消息

[werbenhu]

error="protocol violation: no topic or alias" client=YK-ESP_9ef0 listener=t1 ,我看你大部分这个错误，这个是publish的topic为空，还有一个protocol violation: topic contains wildcards，就是publish的topic有通配符。 其实这些错误码，代码里面都有的，意思是服务端收到的publish就有问题吗？ 你这日志里面没有订阅的日志啊，全是PUBLISH的，你是不是搞错了
