Java实现一个简易HTTP服务器（一）-- socket

-----2019-9-29----------
public class Server {

	public static void main(String[] args) throws IOException {
		ServerSocket serverSocket = new ServerSocket(89);
		System.out.println("Server started at " + new Date() + "
");
		while (true) {
			// 通信socket的获得
			Socket socket = serverSocket.accept();
			System.out.println("client connected...");
			
			//读取数据
			InputStream in = socket.getInputStream();
			byte[] b = new byte[512];
			int len = in.read(b);
			String s = new String(b, 0, len);
			System.out.println("" + socket.getInetAddress() + " " + socket.getPort());
			System.out.println(s);

			//返回数据
			String res = "HTTP/1.1 200 OK
" +
                        "Content-Type: text/html
" + 
                        "
" + 
                        "<html>
" + 
                        "<head>
"+ 
                        "<title>HTTP Server</title>
" + 
                        "</head>
" + 
                        "<body>
" + 
                        "Hello HTTP!
"+ 
                        "</body>
" + 
                        "</html>";
			OutputStream out = socket.getOutputStream();
			out.write(res.getBytes());
			
			//关闭连接，会将in和out一起关闭
			socket.close();
			System.out.println("connection closed...");
			System.out.println();
		}
		serverSocket.close();//ide会报错无法执行到这一行，注释掉就行
