编程检查页面需要基于web.config设置验证 [英] Programmatically check if page requires authentication based on web.config settings

问题描述

我想知道是否有一种方法来检查，如果根据web.config中设置的页面requies认证。基本上，如果有这样的

I would like to know if there is a way to check if a page requies authentication based on the web.config settings. Basically if there is a node like this

  <location path="account">
    <system.web>
      <authorization>
        <deny users="?"/>
      </authorization>
    </system.web>
  </location>

然后我想检查任何页面上，如果它需要认证与否，如果它返回true是帐户目录下。这可能吗？

then I would like to check on any page if it requires authentication or not and to return true if it is under the account directory. Is this possible?

推荐答案

解决方案是创建一个匿名的身份（本金），并把它传递到 CheckUrlAccessForPrincipal 方法。它会确定页是公共的，或者需要验证

The solution is to create an anonymous identity (principal), and pass it into the CheckUrlAccessForPrincipal method. It will determine if the page is public, or requires authentication.

请参阅下面的代码：

var principal = new GenericPrincipal(new GenericIdentity(String.Empty, String.Empty), new string[]{});
bool requiredAuthentication = UrlAuthorizationModule.CheckUrlAccessForPrincipal(Page.AppRelativeVirtualPath, principal, Request.HttpMethod);
