NSwag + System.InvalidOperationException：路径'/ Site'上的方法'get'被多次注册

问题描述

我刚刚设置了一个新的.NET Core 3.1项目，但是在尝试使用NSwag.AspNetCore时遇到一些问题，它与我的控制器有关，但我无法弄清楚。这是我的站点控制器：

[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()));

}

我点击了/ Site，通过邮递员可以正常工作，它调用GetAllSites（）。

但是由于某种原因，当我尝试生成swagger json（点击SwaggerUI）时出现以下错误：

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)

我不确定在这里我可能做错了什么，一切似乎都已正确设置。

对于它的价值，如果那里出了问题，我还将包括自定义BaseController类：

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

如果我用以下方法装饰GetAllSites：

[HttpGet("AllSites")]

它可以工作，但是我不想这么做，我希望能够在我点击/ site时获得所有站点
