java自己实现的httpserver
package my.httpserver;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.BindException;
import java.net.ServerSocket;
import java.net.Socket;
public class Server2 {
private ServerSocket server;
public static void main(String[] args) {
new Server2().start();
}
public void start() {
try {
server = new ServerSocket(8888);
receive();
} catch (BindException e) {
System.out.println("端口已被占用");
} catch(IOException e) {
e.printStackTrace();
}
}
public void receive() {
try {
Socket client = server.accept();
byte[] data = new byte[20480];
int len = client.getInputStream().read(data);
String msg = new String(data, 0, len);
System.out.println(msg);
} catch(IOException e) {
e.printStackTrace();
}
}
}
