信道接收顺序错乱问题 #38

按照我写的服务端代码逻辑，
首先tunnel.broadcast消息A，然后tunnel.broadcast消息B。
在客户端上正常应该先收到A，然后才收到B，但是有时候会先收到B，再收到A。
这种情况怎么处理？

服务端代码：
发送20条信息。
qq 20180217013950
客户端接收到11条错乱的信息，丢了9条。

额，tunnel.broadcast 是异步的操作，循环一个异步的操作不代表会按顺序，这是异步的特性。建议使用队列。

请问有提供相关的函数吗？服务端发送消息我只看到有broadcast

我用async实现了顺序执行，不过还是会出现丢包的现象。
下面是服务端的代码：
0
1
2
下面是客户端接收到的信息：
3
测试了5次，100条信息，丢了15条。

SDK会把Log打出来：

可以到腾讯云控制台下载日志：

看看日志输出的message是什么
