SimpleInjector和Microsoft Webhook ASP.Net Webhooks

我們在Ninject的WebAPI 2項目中成功使用Microsoft ASP.Net Webhooks（特別是Stripe one）。最近我們遷移到SimpleInjector，而其他一切進展順利，我們無法讓這個webhook處理器工作。它不斷拋出以下異常：System.MissingMethodException: 'No parameterless constructor defined for this object.'SimpleInjector和Microsoft Webhook ASP.Net Webhooks

我們Global.asax的是這樣的：

var container = new Container(); 
container.Options.DefaultScopedLifestyle = new AsyncScopedLifestyle(); 
container.Options.PropertySelectionBehavior = new 
InjectPropertySelectionBehavior(); 

// Register our stuff 

container.RegisterMvcControllers(Assembly.GetExecutingAssembly()); 
container.RegisterWebApiControllers(GlobalConfiguration.Configuration); 

container.Verify(); 

GlobalConfiguration.Configuration.DependencyResolver = new 
SimpleInjectorWebApiDependencyResolver(container); 
DependencyResolver.SetResolver(new SimpleInjectorDependencyResolver(container));

我們」重新註冊這樣的WebHook處理程序：

container.Register<IWebHookHandler, StripeWebhookHandler>(Lifestyle.Singleton);

有沒有人得到這個與SimpleInjector一起工作？或者有什麼想法可能是錯誤的？

您爲什麼認爲這與簡單注射器有關？那麼堆棧軌跡顯示沒有涉及簡單注入器的跡象。 – Steven

這是一個很好的觀點，仔細觀察堆棧軌跡，這不是很有幫助。我懷疑它是SimpleInjector的原因是因爲它與Ninject一起工作得很好，而且這是唯一被改變的東西。我應該在上面注意到，StripeWebhookHandler類是我們定義的繼承WebhookHandler（他們）的類，並且具有依賴關係的構造函數。 – mscrivo

堆棧跟蹤似乎意味着Web鉤子通過對其使用Activator.CreateInstance來解析IWebHookHandler，當類型是接口（Web鉤子拋出錯誤的異常消息）時，它顯然會失敗。您是否可能錯過了將IWebHookHandler解決方案重定向到Simple Injector的集成點？ Ninject是否有這樣的集成包？ – Steven

解決方案：

IWebhookHandler需要註冊爲一個集合，所以這樣做：的

container.AppendToCollection(typeof(IWebHookHandler), typeof(StripeWebhookHandler));

代替：

container.Register<IWebHookHandler, StripeWebhookHandler>(Lifestyle.Singleton);

是的伎倆！

我想通了這一點踩踏到Microsoft網絡掛接組裝和SimpleInjector兩者的來源，發現當網絡掛接裝配要求IWebhookHandler類型的所有實例，SimpleInjector在其GetServices執行試圖找到所有IEnumerable<IWebhookHandler>，而不是和所以沒有任何東西。

嘗試解析具有參數構造函數的依賴項時會引發這些類型的異常，但一個或多個參數尚未註冊並因此無法解析，從而導致回退到無參數構造函數某些情況不存在。

確認您已註冊WebHooks工作所需的所有組件。
