UriPathExtensionMapping在MVC 4 [英] UriPathExtensionMapping in MVC 4

问题描述

我如何在MVC4使用UriPathExtensionMapping？我已经添加了映射格式化这样：

How do I use UriPathExtensionMapping in MVC4? I've added the mapping in the formatter such that:

MediaTypeMappings.Add(new UriPathExtensionMapping("json", new MediaTypeHeaderValue("application/json"))

但除非我加一个动词，比如我不能用我的路线上的扩展：

But I can't use the extension on my route unless I add a verb, such as:

routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}.{extension}"

        );

然后，它会承认我需要的介质类型，但它也开始期待扩展名为行动上的参数。例如：

Then it'll recognize my desired media type, but it also starts expecting "extension" as a parameter on the action. Example:

    public object Get(string extension)
    {
    }

而不是只：

    public object Get()
    {
    }

我怎样才能解决这个问题？

How can I resolve this?

谢谢！

推荐答案

我不记得我是否注意到了这个问题，但也可能是因为我明确指定为扩展名，如默认值：

I don't remember if I noticed this problem, but it might be because I explicitly specified the default value for the extension like:

var rF = routes.MapHttpRoute(
    name: "DefaultApi.v1.format",
    routeTemplate: "api/1/{controller}/{action}.{format}/{*id}",
    defaults: new { id = RouteParameter.Optional, format = "json", version = 1 }
);

*注格式=json的与默认开头的行。

我确实也注意到，这有时会不会对尾随参数请求 ID ，工作就像〜/ API / 1 /价值/ get.json / 4 。

I did also notice that this sometimes doesn't work on requests with trailing parameters for id, like ~/api/1/values/get.json/4.
