Web API controller 自定义名称触发错误

Question

Hi I'm a beginner with Web API. So I created a simple function test like this.

  [HttpGet]
    public ActionResult<IEnumerable<string>> Get()
    {
        return new string[] { "value1", "value2" };
    }
    [HttpGet]
    [Route("api/[controller]/test")]
    public string[] test()
    {
        return new string[] { "test1","test2" };
    }

Here I created a custom method test with route specification. But when I try https://localhost:44389/api/values/test , it says {"errors":{"id":["The value 'test' is not valid."]},"title":"One or more validation errors occurred.","status":400,"traceId":"8000001f-0002-e900-b63f-84710c7967bb"}

Plese tell me know how to solve this issue.

You need to use the slash prefix if you want to ignore the route on controller:

[Route("/api/[controller]/test")]

Otherwise your route will be something like /api/values/api/values/test .
