本程序将从http://localhost:80中读取网页内容，整个是以HTML源文件显示，通过本程序对HTTP请求有了一点了解

import java.net.Socket;
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.io.OutputStreamWriter;


public class Main {


	public static void main(String[] args) throws Exception {
		//建立一个到服务器的Socket连接
		Socket s = new Socket("127.0.0.1", 80);
		BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));
		bw.write("GET/HTTP/1.1");
		bw.newLine();
		bw.write("Host:127.0.0.1:80");
		bw.write("Content-Type:text/html");
		bw.newLine();
		bw.newLine();
		bw.flush();
		BufferedReader br = new BufferedReader(new InputStreamReader(s.getInputStream()));
		String str = null;
		while((str = br.readLine()) != null)
		{
			System.out.println(str);
		}
		bw.close();
		br.close();
		s.close();
	}
