MVC 4包罗万象的路线从未达到过

本文介绍了MVC 4包罗万象的路线从未达到过的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

当试图建立一个包罗万象的MVC 4所有航线（这是我发现的几个例子，并根据我的code）它返回一个404错误。我在IIS 7.5上运行此。这似乎是一个简单的解决方案，所以我缺少什么？

一个说明，如果我移动默认的路线上面的包罗万象的路线它的作品。但当然再没有其它控制器都曾经达到。

下面是code：

Route.Config：

routes.MapRoute（            名称：默认，            网址：{控制器} / {行动} / {ID}            默认：新{控制器=家，行动=索引，ID = UrlParameter.Optional}        ）;        routes.MapRoute（            包罗万象，            {*} dynamicRoute            新{控制器=包罗万象，行动=ChoosePage}        ）;

控制器：

公共类CatchAllController：控制器{    公众的ActionResult ChoosePage（字符串dynamicRoute）    {        ViewBag.Path = dynamicRoute;        返回查看（）;    }}

解决方案

由于创建包罗万象路线的最终目标是要能够处理动态URL和我无法找到上述直接回答原来的问题，我从不同的角度来处理我的研究。在这方面，我碰到这个博客帖子就来了：自定义404时，没有路由匹配

该解决方案允许一个给定的URL中的多个部分的处理（即www.mysite/this/is/a/dynamic/route）

下面是最后的定制控制器code：

公众覆盖一个IController CreateController（System.Web.Routing.RequestContext的RequestContext，串controllerName） {     如果（RequestContext的== NULL）     {         抛出新的ArgumentNullException（RequestContext的）;     }     如果（String.IsNullOrEmpty（controllerName））     {         抛出新的ArgumentException（MissingControllerName）;     }     VAR controllerType = GetControllerType（RequestContext的，controllerName）;     //这是通常会返回一个404     //与路线包罗万象控制器替换     如果（controllerType == NULL）     {        //建立与各阶层的动态路径变量        VAR dynamicRoute =的string.join（/，requestContext.RouteData.Values​​.Values​​）;        //路线全部接收控制器        controllerName =包罗万象;        controllerType = GetControllerType（RequestContext的，controllerName）;        requestContext.RouteData.Values​​ [控制器] = controllerName;        requestContext.RouteData.Values​​ [行动] =ChoosePage;        requestContext.RouteData.Values​​ [dynamicRoute] = dynamicRoute;     }     一个IController控制器= GetControllerInstance（RequestContext的，controllerType）;     返回控制器; }

When attempting to create a catch all route in MVC 4 (something I've found several examples of, and based my code on) it returns a 404 error. I'm running this on IIS 7.5. This seems like a straight forward solution, so what am I missing?

One note, if I move the "CatchAll" route above the "Default" route it works. But of course then none of the other controllers are ever reached.

Here is the code:

Route.Config:

routes.MapRoute( name: "Default", url: "{controller}/{action}/{id}", defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional } ); routes.MapRoute( "CatchAll", "{*dynamicRoute}", new { controller = "CatchAll", action = "ChoosePage" } );

Controller:

public class CatchAllController : Controller { public ActionResult ChoosePage(string dynamicRoute) { ViewBag.Path = dynamicRoute; return View(); } }

解决方案

Since the ultimate goal of creating the catchall route was to be able to handle dynamic urls and I was unable to find a direct answer to the original issue above, I approached my research from a different perspective. In doing so I came across this blog post: Custom 404 when no route matches

This solution allows handling of multiple sections within a given url (i.e. www.mysite/this/is/a/dynamic/route)

Here is the final custom controller code:

public override IController CreateController(System.Web.Routing.RequestContext requestContext, string controllerName) { if (requestContext == null) { throw new ArgumentNullException("requestContext"); } if (String.IsNullOrEmpty(controllerName)) { throw new ArgumentException("MissingControllerName"); } var controllerType = GetControllerType(requestContext, controllerName); // This is where a 404 is normally returned // Replaced with route to catchall controller if (controllerType == null) { // Build the dynamic route variable with all segments var dynamicRoute = string.Join("/", requestContext.RouteData.Values.Values); // Route to the Catchall controller controllerName = "CatchAll"; controllerType = GetControllerType(requestContext, controllerName); requestContext.RouteData.Values["Controller"] = controllerName; requestContext.RouteData.Values["action"] = "ChoosePage"; requestContext.RouteData.Values["dynamicRoute"] = dynamicRoute; } IController controller = GetControllerInstance(requestContext, controllerType); return controller; }
