使用ASPNET MVC 4和webapi自定义httphandler和routehandler

我正在研究ASPNET MVC 4和WebApi。 webapi方法将由移动设备使用。 我们需要保护服务，我们正在使用的是以某种特定方式加密数据。

现在，我需要在到达控制器之前解密呼叫。 如果解密的信息有效，它应该照常继续到控制器，如果没有，我将路由用户一些错误方法。

为了实现这一点，我认为最好的选择是自定义HttpHandler和自定义RouteHandler。 我在这里按照教程

public class MvcSecurityRouteHandler:IRouteHandler { public System.Web.IHttpHandler GetHttpHandler(RequestContext requestContext) { return new MvcSecurityHttpHandler(requestContext); } } public class MvcSecurityHttpHandler : IHttpHandler, System.Web.SessionState.IRequiresSessionState, IRouteHandler { public RequestContext RequestContext { get; set; } public MvcSecurityHttpHandler(RequestContext requestContext) { this.RequestContext = requestContext; } public bool IsReusable { get { return true; } } public void ProcessRequest(HttpContext httpContext) { var controllerId = RequestContext.RouteData.GetRequiredString("controllerId"); IController controller = null; IControllerFactory factory = null; try { factory = ControllerBuilder.Current.GetControllerFactory(); controller = factory.CreateController(RequestContext, controllerId); if (controller != null) { controller.Execute(RequestContext); } } finally { factory.ReleaseController(controller); } //string originalPath = httpContext.Request.Path; //HttpContext.Current.RewritePath(httpContext.Request.ApplicationPath, false); //IHttpHandler httpHandler = new MvcHttpHandler(); //httpHandler.ProcessRequest(HttpContext.Current); //HttpContext.Current.RewritePath(originalPath, false); } public IHttpHandler GetHttpHandler(RequestContext requestContext) { throw new NotImplementedException(); } } public class RouteConfig { public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); var defaults = new RouteValueDictionary {{"controllerId", "Home"},{"action", "Index"},{"id", string.Empty}}; var customRoute = new Route("{controllerId}/{action}/{id}", defaults, new MvcSecurityRouteHandler()); routes.Add(customRoute); routes.MapRoute( name: "DefaultWebApi", url: "{controller}/{action}/{id}", defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }); } } 

的Global.asax.cs

  public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); var defaults = new RouteValueDictionary {{"controllerId", "Home"},{"action", "Index"},{"id", string.Empty}}; var customRoute = new Route("{controllerId}/{action}/{id}", defaults, new MvcSecurityRouteHandler()); routes.Add(customRoute); } 

并在Application_Start中

 RegisterRoutes(RouteTable.Routes); 

服务启动后，我在ProcessRequest中创建一个断点，但它没有被命中。 可能会遗漏什么？ 这是正确的做法吗？

如果还没有，则需要首先在global.asax或web.config文件中注册处理程序。
