doGet和doPost的差别 get和post是http协议的两种方法,另外还有head, delete等 这两种方法有本质的差别,get仅仅有一个流,參数附加在url后。...在servlet开发中,以doGet()和doPost()分别处理get和post方法。...首先推断请求时是get还是post,假设是get就调用doGet(), 假设是post就调用doPost()。都会运行这种方法。...2.doPost 它用于client把数据传送到server端,也会有副作用。但优点是能够隐藏传送给server的不论什么数据。Post适合发送大量的数据。...textarea> ……… servlet代码: public class doPostt_servlet extends HttpServlet { public void doPost
2)doPost和doGet的区别?
doget与dopost的区别 GET方法用于获取固定资源,一般并不用于传参数,但是实际开发过程中很多都是在用GET方法来传递参数。...post传递参数 web->from action method->post->XMLHttprequest->servlet->dopost->用于保存和更新数据 Filter过滤器举例: doget...dopost在配置过滤器后便可以正常执行 进入dopost 中文测试:艾索德 测试代码: public void doGet(HttpServletRequest request, HttpServletResponse...; } public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException..., IOException { System.out.println("进入dopost"); String ut=request.getParameter("name"); System.out.println
3.doGet,doPost和service的用法 1)doPost的实例 马克-to-win:我们看到了doGet的用法。这节,我们看看doPost的用法。...javax.servlet.http.HttpServletResponse; public class ServletHello1 extends HttpServlet { protected void doPost
重定向与转发 & doGet()与doPost() (一)重定向与转发 转发(服务器行为) request.getRequestDispatcher("url").forward(request, response...(二)doGet()与doPost() get是用来从服务器上获取数据,而post是用来向服务器传递数据; get将表单中数据按照variable=value的形式,添加到action所指向的URL
