ASP.NET Web API multiple RoutePrefix

问题

The opensource Attribute Routing allows to have multiple route-prefixes. Why does ASP.NET Web API 2.0 does not allow to have multiple RoutePrefix().

[RoutePrefix("api/v1/{abc}/Entity")]
[RoutePrefix("api/v1/{abc}/{xyz?}/Entity")]
public class MyApiController : ApiController
{
   [Route("")]
   public IHttpResult Get()
   {
      return Ok("Hello World");
   }
}

回答1:

You can add a route to the action method also overriding the RoutePrefix with a "~"

example:

[RoutePrefix("api/v1/{abc}/Entity")]
public class MyApiController : ApiController
{
   [Route("")]
   [Route("~/api/v1/{abc}/{xyz?}/Entity")]
   public IHttpResult Get()
   {
      return Ok("Hello World");
   }
}

Notice the line: [Route("~/ api/v1/{abc}/{xyz?}/Entity")]
