使用TCP
客户端
Socket socket = new Socket("ip",端口);
InputStream is = socket.getInputStream();
DataInputStream dis = new DataInputStream(is);
OutputStream os = socket.getOutputStream();
DataInputStream dos = new DataOutputStream(os);
服务器端
ServerSocket serverSocket = new ServerSocket(端口);
Socket socket = serverSocket.accept();
//获取流的方式与客户端一样
读取输入流
byte[] buffer = new byte[1024];
do{
int count = is.read(buffer);
if(count <= 0){ break; }
else{
//对buffer保存或者做些其他操作
}
}
while(true);
使用UDP
客户端和服务器端一样的
DatagramSocket socket = new DatagramSocket(端口);
InetAddress serverAddress = InetAddress.getbyName("ip");
//发送
DatagramPackage packet = new DatagramPacket(buffer, length, host, port);
socket.send(packet);
//接收
byte[] buf = new byte[1024];
DatagramPacket packet = new DatagramPacket(buf, 1024);
Socket.receive(packet);
