Socket 服务端 第二次接收数据发送数据就卡死了~~

Question

socket服务端

Answer 1

你在receveData()里调用ServerSocket.Accept();是毫无道理的， 重新看书吧

Answer 2

用法完全错误.
应该是先侦听到有连接,然后去获取数据
再重新侦听,重新获取
你现在获取数据的while循环里开侦听,不卡死才怪
网上很多现成的代码,好好看看,不要凭想象自己瞎写

Answer 3

有连接的时候，一般另起一个socket来接收数据: Socket handler = listener.Accept();
就像楼上说的receveData()里调用ServerSocket.Accept();去掉
