是否有可能从Java HTTPServletRequest中检索表单名称？ [英] Is it possible to retrieve the form name from a Java HTTPServletRequest?

问题描述

我想获取用于从Java HTTPServletRequest对象发布参数的表单名称。这可能吗。我没有看到任何看起来像它会返回给我的方法。

I would like to get the name of the form used to post parameters from a Java HTTPServletRequest object. Is this possible. I don't see any method that looks like it will return it to me.

推荐答案

HTML表单名称不作为部分提交的请求。如果您需要它（为什么？），您可以将其作为隐藏输入提交：

HTML form name is NOT submitted as part of the request. If you need it (why?) you can submit it as hidden input instead:

<form name="myForm" action="/my_servlet">
  <input type="hidden" name="htmlFormName" value="myForm"/>
  ...

在您的servlet中：

In your servlet:

String htmlFormName = request.getParameterValue("htmlFormName");
