小编Pau*_*aul的帖子

我写了一个asp web-api,我已经使用这个类为api添加了版本.

我的路线看起来像这样:

config.Routes.MapHttpRoute(
    name: "DefaultApi",
    routeTemplate: "{namespace}/{controller}/{id}",
    defaults: new { id = RouteParameter.Optional }
);

config.Services.Replace(typeof(IHttpControllerSelector), new NamespaceHttpControllerSelector(config));

所以我可以访问 https://localhost:44301/v1/test

我现在正在尝试添加Swagger来生成一些api文档(实际上我正在使用Swashbuckle Nuget包)

当我浏览到/swagger页面加载但出现所有控制器的错误时:

Unable to read api 'TestController' from path https://localhost:44301/swagger/api-docs/TestController (server returned undefined)

如果我浏览到https://localhost:44301/swagger/api-docs/TestController它,则会出现NullReferenceException一个堆栈跟踪:
