使用 WCF ServiceRoute 进行 MVC2 路由:Html.ActionLink 呈现不正确的链接！ [英] MVC2 Routing with WCF ServiceRoute: Html.ActionLink rendering incorrect links!

问题描述

我有一个与 MVC2 网站并排存在的 WCF 服务.我希望我的服务 URL 看起来像这样:

I have a WCF service that lives side-by-side with an MVC2 web site. I'd like for my URL for the service to look like this:

http://localhost/projdir/Service

MVC 网站还处于起步阶段，因此它仍然拥有所有样板控制器等.

The MVC site is in its infancy so it still has all its boilerplate controllers etc.

以下代码在 global.asax 中乍一看是有效的:

The following code works at first glance in global.asax:

public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

    routes.Add(new ServiceRoute("Service", new ServiceHostFactory(), 
               typeof(MyService)));

    routes.MapRoute(
        "Default", // Route name
        "{controller}/{action}/{id}", // URL with parameters
        new { controller = "Home", action = "Index", 
              id = UrlParameter.Optional } // Parameter defaults
    );
}

该服务出现在我所描述的位置，并且按照宣传的方式工作.太好了.

The service appears just where I described and works as advertised. Great.

但是，我只是注意到以这种方式对我的代码进行排序会改变我所有的 ActionLink.例如，MVC 站点上的关于"选项卡现在如下所示:

However, I just noticed that ordering my code this way changes all of my ActionLink's. For example, the "About" tab on the MVC site now appears like this:

http://localhost/projdir/Service?action=About&controller=Home

这显然是不正确的(应该是 http://localhost/projdir/Home/About/ ).

This is obviously incorrect (it should be http://localhost/projdir/Home/About/ ).

如果我将 ServiceRoute 添加到默认 MapRoute() 调用下方，则会收到缺少控制器错误.(实际上我得到了一个StructureMapControllerFactory 没有返回控制器的实例"错误，因为我已经连接了 StructureMap，呃，它一开始就不是控制器.)

If I move the ServiceRoute addition below the default MapRoute() call, then I get a missing controller error. (Actually I get a "StructureMapControllerFactory did not return an instance of a controller" error, because I'm wired up with StructureMap, duh, it's not a controller to begin with.)

有趣的是，它似乎只影响了 Html.ActionLink() 的输出.我可以手动输入 http://localhost/projdir/Home/About/ 并进入正确的页面.

Interestingly, it only seems to be affecting the output of Html.ActionLink(). I can manually type in http://localhost/projdir/Home/About/ and get to the correct page.

我犯了什么可怕的新手错误?

What horribly obvious newbie mistake am I making?

推荐答案

尝试在 MVC 路由之后移动服务路由.但是要避免之前遇到的缺少控制器"错误，请添加 MVC 路由 with a 路由约束.这些路由约束可以是正则表达式——基本上你希望你的路由约束是任何 不是服务"的控制器.当请求服务"时，它会通过 WCF 服务路由.

Try moving the Service route after the MVC route. But to avoid the "missing controller" error that you got before, add the MVC route with a Route Constraint. These route constraints can be Regex - basically you'd want your route constraint to be any controller that is not "Service". When a request for "Service" is requested, it will make it fall through and his the WCF Service Route.
