s：表单标签操作参数被删除 [英] s:form tag action parameters being removed

问题描述

我已经搜查和搜查，这正在毁灭我。我有这个：

 < s：form method =postaction =％{methodOne}cssClass =buttons > 
  

emailFormUrl正确返回URL，但参数已被删除。

  public String methodOne（）{
 return anotherClass.methodTwo（id）; 
} 
  

这就是说：

  public static String methodTwo（
 String id）{
 return fastEncode（，longurl / view.jsp，
 new ParameterPairing id，id））; 
} 
  

由于某些原因，id被剥离了，这使我得到了一个验证错误，并没有完成我所需要的操作。据我所知，我们在七月份的紧急安全更新之前没有问题，但它是很少使用的小功能（我想它的移除是一个争论）。

我不想添加隐藏参数，因为我想了解这不起作用的原因，而不是解决方法（我仍然处于繁重的学习部分）在$ servlet环境中，< s：form> $ c>标记使用 ServletUrlRenderer 类来呈现表单url。
如果找不到 action 属性中指定的动作配置，那么动作的文字值（w / o参数） c $ c>属性将被使用。





注意：您需要使用操作名称w / o扩展名才能找到在配置中。因此，如果在配置中有 some_action ，但是<$ c $> some_action？foo = bar 将以参数形式设置$ c> some_action.action？foo = bar 不会被找到，因为 .action 扩展名和参数将被删除。

I have searched and searched and this is destroying me. I have this:

<s:form method="post" action="%{methodOne}" cssClass="buttons">

The emailFormUrl returns the URL correctly but the parameters have been stripped.

  public String methodOne() {
    return anotherClass.methodTwo(id);
  }

Which speaks of:

  public static String methodTwo(
      String id) {
    return fastEncode("", "longurl/view.jsp",
        new ParameterPairing("id", id));
  }

For some reason, the id is being stripped, this leaves me with a validation error and doesn't complete the action that I require. As I am aware we did not have a problem with it before the July urgent security update but it is small functionality that is rarely used (an argument for its removal I guess).

I don't want to add a hidden parameter as I want to understand the reason that this is not working, not a workaround (I am still in the heavy learning part of my career).

解决方案

In servlet environment the <s:form> tag uses ServletUrlRenderer class to render form url. If configuration for the action specified in action attribute cannot be found then literal value (w/o parameters) of an action attribute will be used.

Note: you need to use action name w/o extension in order that it can be found in configuration. So some_action?foo=bar will be set with parameters in form if you have some_action in configuration, but some_action.action?foo=bar won't be found because of .action extension and parameters will be stripped.
