ASP.Net Core Web API custom route not working

问题

I have a ASP.Net Core Web API project, and the following controller:

[Route("/api/v0.1/controller")]
[ApiController]
public class MyController : ControllerBase
{
   [HttpGet("/test")]
   public ActionResult Test() { return null; }
}

but when I run the project, at /api/v0.1/controller/test I get "page not found" and I don't see where I made a mistake.

回答1:

Your method route template contains prefixed /, due to that, the app route couldn't find the appropriate path.

Modify test method route template as follows.

[HttpGet("test")]
public ActionResult Test() { return null; }
