请求行：

package com.my.servlet;
 
 import java.io.IOException;
 import java.io.InputStream;
 import java.io.PrintWriter;
 import java.net.URL;
 
 import javax.servlet.ServletConfig;
 import javax.servlet.ServletContext;

 */

 	private static final long serialVersionUID = 1L;
 
 /**

 */

 super();
 }
 
 	/**
 	 * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
 	 */
 	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
 		
 		response.setContentType("text/html;charset=UTF-8");
 		
 		String method = request.getMethod();//获取使用的HTTP方法；
 		
 		String URi = request.getRequestURI();//获取请求中的资源名部分
 		
 		String protocol = request.getProtocol();//获得协议号
 		
 		String queryString = request.getQueryString();//获得查询语句
 		
 		String servletPath = request.getServletPath();
 		
 		String contextpath = request.getContextPath();//获得web应用路径
 		
 		PrintWriter out = response.getWriter();
 		
 		out.println("请求使用的http方法"+method+"");

 		out.println("请求使用的协议"+protocol+"");

 		out.flush();
 
 		out.close();
 	}
 
 	
 	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
 
 		doGet(request, response);
