{
   public static void main(String [] args)
   {
      try
      {
         URL url = new URL("http://iqiyi.cdn27-okzy.com/20201203/8160_e8fdefb1/index.m3u8");
         System.out.println("URL 为：" + url.toString());
         System.out.println("协议为：" + url.getProtocol());
         System.out.println("验证信息：" + url.getAuthority());
         System.out.println("文件名及请求参数：" + url.getFile());
         System.out.println("主机名：" + url.getHost());
         System.out.println("路径：" + url.getPath());
         System.out.println("端口：" + url.getPort());

         System.out.println("定位位置：" + url.getRef());
		  
	 String str = url.toString();
         int index = str.lastIndexOf("/");
         System.out.println("移除尾部: " + str.substring(0, index + 1));
      }catch(IOException e)
      {
         e.printStackTrace();
      }
