MVC路由问题

问题描述

大家好，

我目前正在使用自己的ViewEngine开发一个MVC4项目，我遇到了一些路由问题。

I使用几种路由格式，似乎我的View没有收到与格式对应的路由值。我相信这是因为它无法抑制许多路线值，但我不知道如何在没有"弄脏"的情况下解决这个问题。我的代码
与另一个循环（例如：对于我的网站的每个部分，为每种可用语言创建路由。）

I am currently develloping an MVC4 project, with my own ViewEngine, and I am experiencing some routing problems.
I use a couple of route formats and it seems my View does not recieves the route values corresponding to the formats. I believe it is because it cannot restrain the many route values, but I do not know how to solve that without "dirtying" my code with another loop (ex: for every section of my website, create a route for every available language.)

以下URL正在运行：mywebsite.com，mywebsite .com / zh，  mywebsite.com/en/mysection

The following URL are working: mywebsite.com, mywebsite.com/en, mywebsite.com/en/mysection

但是，mywebsite.com / mysection应该可以工作，并使用我的MapRouteWithName方法中指定的默认值，但它不会吨。

However, mywebsite.com/mysection should work, and use the default value specified in my MapRouteWithName method, but it doesn't.

我相信这是因为我没有限制默认路线的语言价值，因此"mysection"也是如此。值被视为可能的语言短名称。



此外，我有一条路线（*） （使用以下网址映射："{language} / mysectionname / {params}"）只有在我没有指定params时才有效（例如：mywebsite.com/en/mysectionname"）但不包含params（例如：mywebsite.com/en/mysectionname/0
> 404 Not Found）。
$
当我说它有效时，它实际上会触发一个异常，说"参数字典包含参数（..）的空条目"。 。

再次，我相信这是因为我将参数的类型转换为可以为空的类型时路由使用不当，它会停止抛出此异常，但不会解决实际问题。

（*）此路由指向"AdminInterfaceController"。使用"GenerateSectionDetails"行动。

I believe this happens because I did not restrain the default route's language value, and therefore the "mysection" value is considered as a possible language shortname.

In addition, I have a route (*) (mapped with the following URL: "{language}/mysectionname/{params}") that only works when I do not specify the params (ex: mywebsite.com/en/mysectionname") but does not with params (ex: mywebsite.com/en/mysectionname/0 > 404 Not Found).
When I say it works, it actually fires an exception, saying that "The parameters dictionary contains a null entry for parameter (..)".
Again, I believe this happens because of my bad use of routes for when I convert my parameter's type to a nullable type, it stops throwing this exception, but does not solve the real problem.
(*) this route points to the "AdminInterfaceController" with the "GenerateSectionDetails" action.

我希望我能够解释我的问题，并且以下来源会有所帮助。


     - 第一个片段：我相信它将有助于解决我对路线的错误使用和/或添加足够的RouteRestrictions。

     - 第二个片段：可能有助于解决我的"（...）包含空条目（..）"问题。

I hope I was able to explain my problem, and that the following sources will help.
     - The first snippet: I believe it will help in the solving of my bad use of routes and/or to add the adequate RouteRestrictions.
     - The second snippet: will possibly help in the solving of my "(...)contains a null entry(..)" problem.
