如何在ASP.Net WebApi路由中使用字符串参数中的"/"来处理路由 [英] How do you handle routing in ASP.Net WebApi routing with a '/' in your string parameter

问题描述

我有一个C#WebApi 4项目，我试图在其中包含一个带有字符'/'的字符串参数.例如，我在参数中传递路径:

I have a C# WebApi 4 project where I am trying to have a string parameter with the character '/' in it. For example, I am passing a path in the parameter:

http://localhost/api/MyController/mypath/testing

我希望MyController的Get方法中的id参数填充"mypath/testing".但是，看起来这应该是两个参数，并且找不到路线，因此返回错误.

I want the id parameter in Get method in MyController to be populated with "mypath/testing". However, it looks like the route things this should be two parameters and can't find where to go so it is returning in error.

我认为我需要更改默认路由.当前在WebApiConfig类中，它设置为:

I think I need to change the default route. Currently in the WebApiConfig class it is set to:

config.Routes.MapHttpRoute(
     name: "DefaultApi",
     routeTemplate: "api/{controller}/{id}",
     defaults: new { id = RouteParameter.Optional }
);

但是我不确定要使用哪种类型的模式.有人有什么建议吗?

But I am not sure what type of pattern to use for this. Does anyone have any suggestions?

如果我将URL更改为 http://localhost/api/MyController?id = mypath/testing 并将路由修改为:

If I change my URL to http://localhost/api/MyController?id=mypath/testing and modify the route to be:

config.Routes.MapHttpRoute(
     name: "DefaultApi",
     routeTemplate: "api/{controller}?{id}",
     defaults: new { id = RouteParameter.Optional }
);

然后参数确实消失了.但是，我有一个要求，不要更改URL模式，也不要更改URL编码.

Then the parameter does go though. However, I have a requirement to not change the URL pattern, and to not change the URL encoding.

推荐答案

URL中保留'/'，如果要将其用作参数，则应对其进行编码.您需要这样编码:%2F.

The '/' is reserve in the url, if you want to use it as parameter you should encode it. You need to encode it like this: %2F.
