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
}
}
