c# - 如何让 ASP.NET MVC IAuthorizationFilter 尊重 IgnoreRoute

Question

我正在使用流行的Elmah.MVC错误记录 NuGet 包。所以我可以导航到 /elmah 来查看我的错误日志。我有以下 IgnoreRoute 语句，以便 MVC 忽略 /elmah 路由：

routes.IgnoreRoute("elmah");
routes.IgnoreRoute("elmah/{*pathinfo}");

我编写了以下授权过滤器。当我导航到 /elmah 时，如何阻止下面的过滤器执行。当然，它必须有某种方式来尊重我告诉它忽略的路线？

public class MyFilterAttribute : FilterAttribute, IAuthorizationFilter
{
    public void OnAuthorization(AuthorizationContext filterContext)
    {
        // I don't want /elmah routes to execute this.
    }
}

Answer 1

解决方案是检查正在执行的 ControllerName，如果是 Elmah，我们返回并忽略此请求。

public class MyFilterAttribute : FilterAttribute, IAuthorizationFilter
{
    public void OnAuthorization(AuthorizationContext filterContext)
    {
        // I don't want /elmah routes to execute for this filter.
        string controllerName = filterContext.ActionDescriptor.ControllerDescriptor.ControllerName;
        if (string.Equals(controllerName, "Elmah", StringComparison.Ordinal))
        {
            return;
        }
    }
}
