关于socket，同一个wifi，为什么电脑局域网能通信，手机就不能？？
关于socket，同一个wifi，为什么电脑局域网能通信，手机就不能？？
代码哪里出问题了？？真纠结：
关键性代码：
服务端：
TcpSocketServer ：

public class TcpSocketServer {
public TcpSocketServer(){
}
public void startWifi(int port,String buffer)throws Exception{
//新建ServerSocket对象,端口为传进来的port;
ServerSocket ss = new ServerSocket(port);
//新建Socket通信对象，接受客户端发来的请求accept();
Socket s = ss.accept();
//创建输入流对象InputStream
InputStream bais = new ByteArrayInputStream(buffer.getBytes());
//创建输出流对象OutputStream
OutputStream out = s.getOutputStream();
byte[] buff = new byte[1024];
while(bais.read(buff) > 0){
out.write(buff);
}
s.close();
}
}
