Asp.net mvc 将所有请求转发给MVC中的委托处理程序

我有一个用MVC编写的视图。我在

CustomRouteFilter

的以下方法中捕获所有请求

public class CustomRoutesHandler : RouteBase
{
    public override RouteData GetRouteData(HttpContextBase httpContext)
    {
        //my code
    }
}

在这里，我想将所有请求转发给自定义的

DelegateHandler

的

SendAsync（）

方法。有人能帮我吗

public class RequestHandler : DelegatingHandler
{
    protected override async Task<HttpResponseMessage> SendAsync(
        HttpRequestMessage request, CancellationToken cancellationToken)
    {
        //my code
    }
}

公共类请求处理程序：DelegatingHandler
{
受保护的覆盖异步任务SendAsync(
HttpRequestMessage请求，CancellationToken CancellationToken）
{
//我的代码
}
}

如果您可以从CustomRouteHandler直接在RequestHandler上调用方法，则以下操作有效：

客户路线管理员：

public class CustomRoutesHandler : RouteBase
{
    Route route;
    public CustomRoutesHandler(Route route)
    {
        this.route = route;
    }

    public override RouteData GetRouteData(HttpContextBase httpContext)
    {
        RequestHandler requestHandler = new RequestHandler();
        HttpRequestMessage request = new HttpRequestMessage();
        HttpResponseMessage response = requestHandler.SendAsync(request).Result;
        return route.GetRouteData(httpContext);
    }

    public override VirtualPathData GetVirtualPath(RequestContext requestContext, RouteValueDictionary values)
    {
        return route.GetVirtualPath(requestContext, values);
    }
}

public class RequestHandler : DelegatingHandler
{
    public Task<HttpResponseMessage> SendAsync(HttpRequestMessage request)
    {
        CancellationToken cancellationToken = CancellationToken.None;
        return SendAsync(request, cancellationToken);
    }
    protected override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
    {
        HttpResponseMessage response = new HttpResponseMessage(HttpStatusCode.OK);
        var tsc = new TaskCompletionSource<HttpResponseMessage>();
        tsc.SetResult(response); 
        return tsc.Task;
    }
}

public class RouteConfig
{
    public static void RegisterRoutes(RouteCollection routes)
    {
        Route route = routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        );
        routes.Remove(route);
        routes.Add(new CustomRoutesHandler(route));
    }
}

RequestHandler:

public class CustomRoutesHandler : RouteBase
{
    Route route;
    public CustomRoutesHandler(Route route)
    {
        this.route = route;
    }

    public override RouteData GetRouteData(HttpContextBase httpContext)
    {
        RequestHandler requestHandler = new RequestHandler();
        HttpRequestMessage request = new HttpRequestMessage();
        HttpResponseMessage response = requestHandler.SendAsync(request).Result;
        return route.GetRouteData(httpContext);
    }

    public override VirtualPathData GetVirtualPath(RequestContext requestContext, RouteValueDictionary values)
    {
        return route.GetVirtualPath(requestContext, values);
    }
}

public class RequestHandler : DelegatingHandler
{
    public Task<HttpResponseMessage> SendAsync(HttpRequestMessage request)
    {
        CancellationToken cancellationToken = CancellationToken.None;
        return SendAsync(request, cancellationToken);
    }
    protected override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
    {
        HttpResponseMessage response = new HttpResponseMessage(HttpStatusCode.OK);
        var tsc = new TaskCompletionSource<HttpResponseMessage>();
        tsc.SetResult(response); 
        return tsc.Task;
    }
}

public class RouteConfig
{
    public static void RegisterRoutes(RouteCollection routes)
    {
        Route route = routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        );
        routes.Remove(route);
        routes.Add(new CustomRoutesHandler(route));
    }
}
