public static void main(String[] args) throws IOException {
String path = "http://localhost:8080/myweb/mail.html?name=lisi";
URL url = new URL(path);
System.out.println(url.getProtocol());//获取协议
System.out.println(url.getHost());//获取主机
System.out.println(url.getPort());//获取端口
System.out.println(url.getPath());//得到资源路径/myweb/mail.html
System.out.println(url.getFile());///myweb/mail.html?name=lisi
URLConnection conn = url.openConnection();//和服务器端连接
//读取服务器发回的数据
InputStream in = conn.getInputStream();
byte[] arr = new byte[1024];
int len = in.read(arr);
System.out.println(new String(arr,0,len));
}
