此文就是作为笔记使用，以防忘记，下面是全部代码：

此文请求的是web程序的一个servlet 定义了一个post和get方法 ，get方法传入的name和age，post传入的参数是name1和age1 。

你可以自己建一个简单的站点用于测试：

下面是我的servlet 主要代码：

        public void doGet(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException 
    {
        response.setContentType("text/html;charset=gbk");

        String name=request.getParameter("name").toString();
        String age=request.getParameter("age").toString();

        PrintWriter out = response.getWriter();
        out.print("你使用Get发送请求，你的名字是："+name+",你的年龄是："+age);
    }


    public void doPost(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException 
    {
        response.setContentType("text/html;charset=gbk");

        String name=request.getParameter("name1").toString();
        String age=request.getParameter("age1").toString();

        PrintWriter out = response.getWriter();
        out.print("你使用Post发送请求，你的名字是："+name+",你的年龄是："+age);
    }
