swagger--Failed to load API definition.

 

 

 

 打開

http://localhost:5000/swagger/v1/swagger.json

 

提示錯誤

An unhandled exception occurred while processing the request.
NotSupportedException: HTTP method "GET" & path "api/Report/ExportUserRegisterData" overloaded by actions - XXX.Application.Report.ReportApplication.ExportUserRegisterData (XXX.Application),XXX.Application.Report.ReportApplication.ExportUserRegisterData (XXX.Application). Actions require unique method/path combination for Swagger 2.0. Use ConflictingActionsResolver as a workaround
Swashbuckle.AspNetCore.SwaggerGen.SwaggerGenerator.CreatePathItem(IEnumerable<ApiDescription> apiDescriptions, ISchemaRegistry schemaRegistry)

 

原因

有Get類型的重載的接口方法

 

解決方法

options.ResolveConflictingActions(apiDescriptions => apiDescriptions.First());

意思是swagger只會取其中一個Action

具體位置

//自動生成Api文檔
            services.AddSwaggerGen(options =>
            {
                options.ResolveConflictingActions(apiDescriptions => apiDescriptions.First());
            });
