IDEA(2020版)实现HttpServletResponse对象 – 每天进步一点点

本文主要介绍在IDEA中实现HttpServletResponse对象

源代码下载： https://box356.lanzoub.com/ij9CW2s8vp2h

1.获取请求行信息的相关方法
右击src—＞New—>Create New Servlet，名称就叫TestServlet4_17

代码参考如下：

importjavax.servlet.ServletException;importjavax.servlet.annotation.WebServlet;importjavax.servlet.http.HttpServlet;importjavax.servlet.http.HttpServletRequest;importjavax.servlet.http.HttpServletResponse;importjava.io.IOException;importjava.io.PrintWriter;@WebServlet(name="TestServlet4_17",value="/test417")public class TestServlet4_17 extends HttpServlet{public void doGet(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException{response.setContentType("text/html;charset=utf-8");PrintWriter out=response.getWriter();// 获取请求行的相关信息 out.println("getMethod : "+ request.getMethod()+"<br />");out.println("getRequestURI : "+ request.getRequestURI()+"<br />");out.println("getQueryString:"+ request.getQueryString()+"<br />");out.println("getProtocol : "+ request.getProtocol()+"<br />");out.println("getContextPath:"+ request.getContextPath()+"<br />");out.println("getPathInfo : "+ request.getPathInfo()+"<br />");out.println("getPathTranslated : "+ request.getPathTranslated()+"<br />");out.println("getServletPath:"+ request.getServletPath()+"<br />");out.println("getRemoteAddr : "+ request.getRemoteAddr()+"<br />");out.println("getRemoteHost : "+ request.getRemoteHost()+"<br />");out.println("getRemotePort : "+ request.getRemotePort()+"<br />");out.println("getLocalAddr : "+ request.getLocalAddr()+"<br />");out.println("getLocalName : "+ request.getLocalName()+"<br />");out.println("getLocalPort : "+ request.getLocalPort()+"<br />");out.println("getServerName : "+ request.getServerName()+"<br />");out.println("getServerPort : "+ request.getServerPort()+"<br />");out.println("getScheme : "+ request.getScheme()+"<br />");out.println("getRequestURL : "+ request.getRequestURL()+"<br />");}public void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException{doGet(request, response);}}

在浏览器里输入下面的地址，注意和你实际的地址相匹配

http://localhost:8080/Servlet01_war_exploded/test417
运行结果如下：

2.获取请求头的相关方法
右击src,创建一个新的Servlet，名字为TestServlet4_18
