C# SimpleInjector和Microsoft Webhook ASP.Net Webhook

在我们与Ninject的WebAPI 2项目中，我们已经成功地使用了Stripe（特别是Stripe）。最近我们迁移到SimpleInjector，虽然其他一切都很顺利，但我们无法让这个webhook处理器工作。它不断引发以下异常：

System.MissingMethodException:“没有为此对象定义无参数构造函数。”

我们正在注册WebHook处理程序，如下所示：

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));

container.Register（lifesture.Singleton）

有人用SimpleInjector做过这个吗？或者你知道什么可能是错误的吗？
当试图解析具有参数构造函数但一个或多个参数尚未注册因而无法解析的依赖项时，会引发此类异常，从而导致返回到在某些情况下不存在的无参数构造函数

验证您已注册Webhook工作所需的所有组件。
解决方案：

IWebhookHandler需要注册为集合，因此执行以下操作：

container.Collection.Append（typeof（IWebHookHandler）、typeof（StripeWebhookHandler））

而不是：

container.Register（lifesture.Singleton）

这就是诀窍

我通过深入到Microsoft Webhook程序集和SimpleInjector的源代码中发现，当Webhook程序集请求所有类型为
IWebhookHandler
的实例时，SimpleInjector，在它的GetServices实现中，我们试图找到所有的
IEnumerable
，结果却一无所获。
为什么您认为这与简单注入器有关？堆栈跟踪显示没有简单注入器参与其中的迹象。这是一个很好的观点，仔细观察堆栈跟踪，它不是很有帮助。我之所以怀疑它是SimpleInjector，是因为它在Ninject上工作得非常好，这是唯一改变的东西。我应该在上面注意到，StripeWebhookHandler类是我们定义的一个类，它继承了WebhookHandler（他们的），并且有一个具有依赖项的构造函数。堆栈跟踪似乎暗示web钩子正在通过在其上使用Activator.CreateInstance解析IWebHookHandler，当类型是接口时，它显然会失败（web钩子抛出错误的异常消息）。您是否缺少将IWebHookHandler的解析重定向到Simple Injector的某个集成点？Ninject是否有您使用的此类集成包？我们在此处使用集成说明：。具体调用
config.InitializeReceiveStripeWebHooks（）；
在我们的Web API配置设置中。我们使用的Ninject包是Ninject、Ninject.Extensions.Factory和Ninject.Web.Common…我相信没有什么不寻常的地方。感谢您的快速响应Steven。我在OP中更新了Stacktrace，希望它更有用。我注意到的一点是StripeWebHomeReceiver有2个构造函数，这可能是问题所在？我尝试使用以下方法显式注册它：
container.Register（（）=>new StripeWebHookReceiver（），Lifestyle.Singleton）；
，但这不起作用
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));
