使用api版本控制的Autofac和swagger给出了例外

Question

从visual studio运行我的项目时，我得到以下异常，它是一个ASP.NET核心项目。

似乎依赖项被注册两次，因此“System.ArgumentException：已经添加了具有相同键的项目”。

它似乎也与路由有关，但我找不到调试它的方法。

它似乎也与Api中的Versioning有关，因为如果删除此代码，异常就会消失。

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

任何人都见过这个或有想法如何调试它。

Answer 1

尝试添加此代码：

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

                    opt.SubstituteApiVersionInUrl = true;
                });
