使用api版本控制的Autofac和swagger給出了例外

Question

從visual studio運行我的項目時，我得到以下異常，它是一個ASP.NET核心項目。

似乎依賴項被注冊兩次，因此“System.ArgumentException：已經添加了具有相同鍵的項目”。

它似乎也與路由有關，但我找不到調試它的方法。

它似乎也與Api中的Versioning有關，因為如果刪除此代碼，異常就會消失。

services.AddApiVersioning(o =>
        {
            o.AssumeDefaultVersionWhenUnspecified = true;
            o.DefaultApiVersion = new ApiVersion(1, 0);
            o.ReportApiVersions = true;
            o.ApiVersionSelector = new CurrentImplementationApiVersionSelector(o);
        });

任何人都見過這個或有想法如何調試它。

Answer 1

嘗試添加此代碼：

services.AddMvcCore().AddVersionedApiExplorer(
                opt =>
                {
                    opt.GroupNameFormat = "'v'VVV";

                    opt.SubstituteApiVersionInUrl = true;
                });

Answer 2

您應該能夠通過添加，

<GenerateDocumentationFile>true</GenerateDocumentationFile>
