android：Socket编程模拟骂街

2024-11-29 来源：个人技术集锦

　　所谓"骂街"，就两个人"A","B"对骂，A骂B的过程是这样的： A发出信息---B接收信息--B处理信息（理解A骂的话，想着怎么回应A）--B发送

信息（反骂）--A接收信息--A处理信息（理解B骂的话，想着怎么回应B）。循环这个过程。

　　最开始编写时我遇到了一个稀奇古怪的问题，我的客户端在模拟器上时一切正常；当在真实的android客户端上时，服务器能收到客户端发送的信息，而客户端接收不到服务器返回的信息，我以为是防火墙或者局域网搞的怪，但跟为奇怪的是在调试模式下客户端还能收的服务器放回的信息，后来我更改了客户端发送和接收的处理流程问题得到了解决
