Server发送PUBLISH消息到Client，Client接收之后需要确认收到嘛，就返回PUBREC吧；但此时Client仅仅是把数据发送出去了而已，至于Server端收不收到那就不得而知.<br>2. Server可能收到了PUBREC，也可能没有收到<br>    a. Server收到了PUBREC， 这时候就表示Client收到消息了，表示成功递送消息了。<br>    b. Server没有收到PUBREC，等待一定时间后，重发PUBLISH即可。<br><br>在1中，Client收到PUBLISH后就把数据保存在数据库中，如果收到重复PUBLISH重数据库就可以知道是重复数据。<br>在2中，超时就重传PUBLISH即可。<br>感觉这样两步完全满足QoS2了呀！！<br><br><br>其实我在设计一套私有IM协议，用于自己的App中，希望能加你QQ探讨一下MQTT的QoS2问题。<br>我的QQ：357545146<img src ="http://www.blogjava.net/yongboy/aggbug/432258.html" width = "1" height = "1" /><br><br><div align=right><a style="text-decoration:none;" href="http://www.blogjava.net/yongboy/" target="_blank">Haven</a> 2017-01-10 13:03 <a href="http://www.blogjava.net/yongboy/archive/2017/01/10/409689.html#432258#Feedback" target="_blank" style="text-decoration:none;">发表评论</a></div>]]></description></item><item><title>re: MQTT协议笔记之发布流程</title><link>http://www.blogjava.net/yongboy/archive/2017/01/05/409689.html#432243</link><dc:creator>nieyong</dc:creator><author>nieyong</author><pubDate>Thu, 05 Jan 2017 07:20:00 GMT</pubDate><guid>http://www.blogjava.net/yongboy/archive/2017/01/05/409689.html#432243</guid><description><![CDATA[@Haven<br><br>兄弟，针对QoS2，为了便于说明，我们先假设一个方向，Server -&gt; Client：<br><br>			----PUBLISH---&gt; 	<br>			&lt;----PUBREC----<br>			----PUBREL----&gt;<br>			&lt;----PUBCOMP---<br><br>1. Server发送PUBLISH消息到Client，Client接收之后需要确认收到嘛，就返回PUBREC吧；但此时Client仅仅是把数据发送出去了而已，至于Server端收不收到那就不得而知<br>2. Server接收ClientPUBREC消息之后，需要回一个PUBREL消息告诉Client自己收到啦，同样道理也仅仅只是发送出去，Client是不是能收到的这个响应，心里面也没谱呀<br>3. Client收到来自Server的PUBREL之后，就非常明白自己针对PUBLISH消息做出的PUBREC响应消息在Server端是已经收到啦，但是需要告诉Server，自己收到它的再三确认啦<br>4. Server端此时等待Client上报PUBCOMP消息，一旦接收到之后，表示针对某个消息双方都再三确认了，这事就没有问题啦<br><br>其核心所设定网络是不靠谱的，任何一次发送数据到对端，都有可能因收不到（比如发送之后，某一端断网啦，或中间路由设备因为容量满了抛弃啦）。<br><br>好比双发约定一件事：<br><br>Server - 我给你说说这件事....<br>Client - 我同意了你这样做。<br>Server - 你确定你同意了？<br>Client - 是的，我同意了。<br>Server - OK，那这事就这么定了，我知道该怎么做啦。<img src ="http://www.blogjava.net/yongboy/aggbug/432243.html" width = "1" height = "1" /><br><br><div
