jsp代码
<form > 姓名:<input name="name" type="text"/> 年龄:<input name="age" type="text"/> <input type="button" class="get" value="get提交"/> <input type="button" class="post" value="post提交"/> <input type="button" class="ajax" value="ajax提交"/> </form> <div id="box"></div>
servlet代码
//get public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setContentType("text/html"); response.setCharacterEncoding("utf-8"); response.setContentType("text/html;charset=utf-8"); String name = request.getParameter("name"); String age = request.getParameter("age"); if (name == null || name == "") { name = "测试名字admin"; } if (age == null || age == "") { age = "测试年龄100"; } user user = new user(1, name, age); PrintWriter out = response.getWriter(); JSONObject jsonObj = JSONObject.fromObject(user); out.print(jsonObj); out.flush(); out.close(); }
//post public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // response.setContentType("text/html"); request.setCharacterEncoding("utf-8"); response.setCharacterEncoding("utf-8"); response.setContentType("text/html;charset=utf-8"); String name = request.getParameter("name"); if (name == null || name == "") { name = "测试名字admin"; } String age = request.getParameter("age"); if (age == null || age == "") { age = "测试年龄100"; } user user = new user(1, name, age); PrintWriter out = response.getWriter(); JSONObject jsonObj = JSONObject.fromObject(user); out.print(jsonObj); out.flush(); out.close(); }
