大摇大摆的版本控制不起作用。它显示所有endpoint，不管所选的API版本如何

Question

namespace Application.Controllers
{
    [ApiVersion("1")]
    [ApiVersion("2")]
    [ApiController]
    [Route("api/v{version:apiVersion}")]
    public class CustomController: ControllerBase
    {
        [HttpGet]
        [Route("result")]
        public IActionResult GetResult()
        {
            return Ok("v1")
        }

        [HttpGet]
        [MapToApiVersion("2")]
        [Route("result")]
        public IActionResult GetResult(int number)
        {
            return Ok("v2")
        }
    }
}

            services.AddApiVersioning(
                options =>
                {
                    options.ReportApiVersions = true;
                });

            services.AddSwaggerGen(c =>
            {
                c.SwaggerDoc($"v1", new OpenApiInfo { Title = "api1", Version = $"v1" });

                c.SwaggerDoc($"v2", new OpenApiInfo { Title = "api2", Version = $"v2" });         
         

                c.OperationFilter<RemoveVersionParameterFilter>();
                c.DocumentFilter<ReplaceVersionWithExactValueInPathFilter>();
                c.EnableAnnotations();
            });

app.UseSwagger().UseSwaggerUI(c =>
            {
                c.SwaggerEndpoint($"/swagger/v1/swagger.json", $"api1 v1");
                c.SwaggerEndpoint($"/swagger/v2/swagger.json", $"api2 v2");
            });

加载后，我得到一个错误：Fetch error undefined/swagger/v1/swagger.json但是如果我将第二条路由更改为“resutltwo”，我可以在swagger中观察到两个endpoint，忽略当前版本(api1 v1或api2 v2)

如何才能在每个API版本中只看到1个endpoint？

谢谢咆哮S的帮助！

我刚加了一句

 services.AddApiVersioning(apiVersioningOptions =>
            {
                apiVersioningOptions.ReportApiVersions = true;
                apiVersioningOptions.ApiVersionReader = new UrlSegmentApiVersionReader();
            });

和

 c.DocInclusionPredicate((version, desc) =>
                {
                    var endpointMetadata = desc.ActionDescriptor.EndpointMetadata;

                    if (!desc.TryGetMethodInfo(out MethodInfo methodInfo))
                    {
                        return false;
                    }

                    var specificVersion = endpointMetadata
                            .Where(data => data is MapToApiVersionAttribute)
                            .SelectMany(data => (data as MapToApiVersionAttribute).Versions)
                            .Select(apiVersion => apiVersion.ToString())
                            .SingleOrDefault();

                    if (!string.IsNullOrEmpty(specificVersion))
                    {
                        return $"v{specificVersion}" == version;
                    }

                    var versions = endpointMetadata
                            .Where(data => data is ApiVersionAttribute)
                            .SelectMany(data => (data as ApiVersionAttribute).Versions)
                            .Select(apiVersion => apiVersion.ToString());

                    return versions.Any(v => $"v{v}" == version);
                });
