Mat*_*s F 2 asp.net-mvc forms-authentication
我有以下路线:
{语言}/{控制器} .mvc/{动作}/{ID}
一旦用户选择了语言,它就会以路由值语言进行维护.
HTTP://本地主机:4000 /德/ Account.mvc /注册
如果用户点击需要修改的页面,我会遇到问题.然后他被重定向到http:// localhost:4000/Account.mvc/Login?ReturnUrl =%2fde%2fAccount.mvc%2fProfileData
登录页面在web.config中配置,不允许路由中的参数.登录后的页面正常(http:// localhost:4000/de/Account.mvc/ProfileData),但登录页面本身没有路由值语言.
我怎样才能解决这个问题?

我使用了Darin的答案,但必须包含原始Authorize过滤器(AuthorizeAttribute.cs)中的所有代码.原因记录在该文件中.它处理未经授权的用户可能从缓存中获取安全页面的情况.
以下是代码中的注释:
// ** IMPORTANT **
// Since we're performing authorization at the action level, the authorization code runs
// after the output caching module. In the worst case this could allow an authorized user
// to cause the page to be cached, then an unauthorized user would later be served the
// cached page. We work around this by telling proxies not to cache the sensitive page,
// then we hook our custom authorization code into the caching mechanism so that we have
// the final say on whether a page should be served from the cache.

表单身份验证的问题是您不能拥有动态配置的登录URL.这就是ASP.NET团队设计框架的方式.在某些时候,将调用FormsAuthentication.RedirectToLoginPage方法,该方法将仅重定向到web.config中的硬编码URL.
我可以看到两种可能的解决方法:
以下是使用自定义属性的示例:
[AttributeUsage(AttributeTargets.Method | AttributeTargets.Class, Inherited = true, AllowMultiple = true)]
public class RequiresAuthenticationAttribute : FilterAttribute, IAuthorizationFilter
{
public void OnAuthorization(AuthorizationContext filterContext)
{
IPrincipal user = filterContext.HttpContext.User;
if (!user.Identity.IsAuthenticated)
{
filterContext.Result = new RedirectResult("CALCULATE YOUR LOGIN URL HERE FROM ROUTES");
}
}
}
