asp.net-core - NSwag + System.InvalidOperationException : The method 'get' on path '/Site' is registered multiple times

Question

我刚刚设置了一个新的 .NET Core 3.1 项目，但在尝试使用 NSwag.AspNetCore 时遇到了一些问题，这与我的 Controller 有关，但我无法弄清楚。这是我的站点 Controller :

[Route("[controller]")]
[ApiController]
public class SiteController : BaseController
{
    private readonly ISiteService _siteService;
    public SiteController(ISiteService siteService, ILogger<SiteController> logger) : base(logger)
    {
        _siteService = siteService;
    }

    [HttpGet]
    public IActionResult GetAllSites() => (ReadService(() => _siteService.Sites()));

    [HttpGet("domainName/{domainName}")]
    public IActionResult GetByDomainName(string domainName) => (ReadService(() => _siteService.Site(domainName)));

    [HttpGet("status")]
    public Task<IActionResult> GetStatusAsync() => (ReadServiceAsync(async () => await _siteService.GetApiStatusAsync()));

    [HttpGet("lookupdata")]
    public Task<IActionResult> GetLookupDataAsync() => (ReadServiceAsync(async () => await _siteService.GetLookupDataAsync()));

}

我正在点击/Site，它通过 postman 工作正常，它调用 GetAllSites()。

但由于某种原因，我在尝试生成 swagger json(点击 SwaggerUI)时收到以下错误:

System.InvalidOperationException: The method 'get' on path '/Site' is registered multiple times.
    at NSwag.Generation.AspNetCore.AspNetCoreOpenApiDocumentGenerator.AddOperationDescriptionsToDocument(OpenApiDocument document, Type controllerType, List`1 operations, OpenApiDocumentGenerator swaggerGenerator, OpenApiSchemaResolver schemaResolver)
    at NSwag.Generation.AspNetCore.AspNetCoreOpenApiDocumentGenerator.GenerateForControllers(OpenApiDocument document, IGrouping`2[] apiGroups, OpenApiSchemaResolver schemaResolver)
    at NSwag.Generation.AspNetCore.AspNetCoreOpenApiDocumentGenerator.GenerateAsync(ApiDescriptionGroupCollection apiDescriptionGroups)
    at NSwag.Generation.AspNetCore.AspNetCoreOpenApiDocumentGenerator.GenerateAsync(Object serviceProvider)
    at NSwag.AspNetCore.OpenApiDocumentProvider.GenerateAsync(String documentName)
    at NSwag.AspNetCore.Middlewares.OpenApiDocumentMiddleware.GenerateDocumentAsync(HttpContext context)
    at NSwag.AspNetCore.Middlewares.OpenApiDocumentMiddleware.GetDocumentAsync(HttpContext context)
    at NSwag.AspNetCore.Middlewares.OpenApiDocumentMiddleware.Invoke(HttpContext context)

我不确定我在这里做错了什么，一切似乎都已正确设置。

为了它的值(value)，如果那里有问题，我还包括自定义 BaseController 类:

[ApiController]
public abstract class BaseController : ControllerBase
{
    private ILogger _logger;
    protected BaseController(ILogger logger)
    {
        _logger = logger;
    }
}

如果我用以下方式装饰 GetAllSites:

[HttpGet("AllSites")]

它会工作，但我不想那样做，我希望在我点击/site 时能够获得所有站点

对于每个操作，您可以指定如下路径:

[HttpGet]
[Route("{id:min(1)}/GetItems1", Name = "GetHotelFacilities")]
public async Task getItems1(){}

[HttpGet]
[Route("{id:min(1)}/GetItems2", Name = "GetHotelFacilities")]
public async Task getItems2(){}
