c# - 如何从 ASP.NET MVC 中的 HttpModule 执行 Controller 操作？

Question

我有以下 IHttpModule，我正在尝试找出如何从 Controller 针对给定的绝对或相对 URL 执行操作。

public class CustomErrorHandlingModule : IHttpModule
{
    #region Implementation of IHttpModule

    public void Init(HttpApplication context)
    {
        context.Error += (sender, e) => 
            OnError(new HttpContextWrapper(((HttpApplication)sender).Context));
    }

    public void Dispose()
    {}

    public void OnError(HttpContextBase context)
    {
        // Determine error resource to display, based on HttpStatus code, etc.
        // For brevity, i'll hardcode it for this SO question.
        const string errorPage = @"/Error/NotFound";

        // Now somehow execute the correct controller for that route.
        // Return the html response.
    }
}

如何做到这一点？

Answer 1

沿线的东西应该做的工作:

public void OnError(HttpContextBase context)
{
    context.ClearError();
    context.Response.StatusCode = 404;

    var rd = new RouteData();
    rd.Values["controller"] = "error";
    rd.Values["action"] = "notfound";
    IController controller = new ErrorController();
    var rc = new RequestContext(context, rd);
    controller.Execute(rc);
}
