服务器端的
ServerSocket ss = new ServerSocket(1234)
Socket socket=null
BufferedReader in
PrintWriter out
while (true) {
socket = ss.accept()
in = new BufferedReader(new InputStreamReader(socket.getInputStream()))
out = new PrintWriter(socket.getOutputStream(),true)
String line = in.readLine()
out.println("you input is :" + line)
out.close()
in.close()
socket.close()
}
可以参考一下这段代码
//1. 构造ServerSocket实例，指定服务端口。
ServerSocket servSock = new ServerSocket(servPort)
while(true)
{
// 2.调用accept方法，建立和客户端的连接
Socket clntSock = servSock.accept()
SocketAddress clientAddress =
clntSock.getRemoteSocketAddress()
System.out.println("Handling client at " + clientAddress)
// 3. 获取连接的InputStream,OutputStream来进行数据读写
InputStream in = clntSock.getInputStream()
OutputStream out = clntSock.getOutputStream()
while((recvMsgSize = in.read(receiveBuf)) != -1)
{
out.write(receiveBuf, 0, recvMsgSize)
}
// 4.操作结束，关闭socket.
clntSock.close()
}
