java--模拟浏览器

模拟一个浏览器客户端向服务器发请求，接收并显示响应消息。 import java.io.IOException; import java.io.InputStream; import java.io.PrintWriter; import java.net.Socket; public class browse { public static void main(String[] args) throws IOException { Socket s=new Socket("www.hncu.net", 80); PrintWriter pw=new PrintWriter(s.getOutputStream(), true); pw.println("GET / HTTP/1.1"); pw.println("Accept: */*"); pw.println("Host: www.hncu.net"); pw.println("Connection: keep-alive"); pw.println();//必须要有一个空行 InputStream in=s.getInputStream(); byte buf[]=new byte[512]; int len=0; while((len=in.read(buf))!=-1){ String str=new String(buf,0,len,"utf-8"); System.out.println(str); } } }

以下是请求的网页代码部分，会被如果myelipese像浏览器可以解析，这里则会显示www.hncu.net网站
