利用java的post模拟登录网站时，hiden参数问题
我现在是要用java post编写一个模拟网页登陆的程序，在用post提交参数时，除了用户名和密码外，还必须提供两个hiden的参数，否则无法登录，请问如何获取这两个影藏的参数，也就是说服务器会不会传回一些参数里面含有这种hiden的值，一般传回的值会放在那里，我用java的什么函数去获取？谢谢了！！！ --------------------编程问答-------------------- hiddle和text的类型差不多，都可以用request.getParameter("textName")获得，唯一不同的地方是hiddle是隐藏的，在客户端的浏览器看不到。这些值都是传递给服务器的，当然也可以写在jsp页面里面，由另外一个jsp页面获得。。。但是 说到底，还是由服务器获得的。。。 --------------------编程问答--------------------
差不多、不过你问服务器是否传回这些参数。。这个是看你要不要这些参数。要的话就有可以用在客服端获得request.getParameter("参数Name"); --------------------编程问答-------------------- 对不起，我实在是个菜鸟，对这个真不懂，请问request在java se 里面是如何定义的 --------------------编程问答-------------------- 还有就是我是想在客户端获得这个隐藏的值，你刚才给的request.getParameter("textName")方法应该是再服务器端获取客户端传入的值吧，请问在客户端如何获取这些值？ --------------------编程问答-------------------- 还有就是我用的是javaSE编程，不涉及jsp这类的 --------------------编程问答-------------------- 你把代码贴出来看看。。。 --------------------编程问答-------------------- 隐藏 J2SE 搞不明白 看看代码吧 前台和后台都给我丢上来 --------------------编程问答-------------------- hidden 和 text 无任何区别.除了页面上可不可见. --------------------编程问答-------------------- hidden要放在form里一同提交 --------------------编程问答--------------------

这个是我自己写的javaSE的代码，在我们自己做的没有隐藏的参数上是可以运行的 --------------------编程问答-------------------- 建议使用httpClient
啥东西都能出来
补充：Java , Web 开发
