如何在ninject中注册HttpContextBase？我没有明确地绑定它

Question

我在NinjectWebCommon.RegisterServices方法中为HttpContextBase创建了一个绑定,但是当我尝试在我的控制器或服务中引用它时,我收到一条错误消息.

这是绑定:

kernel.Bind<HttpContextBase>().ToMethod(context => new HttpContextWrapper(HttpContext.Current)).InRequestScope();

这是错误消息:

Error activating HttpContextBase
More than one matching bindings are available.
Activation path:
 2) Injection of dependency HttpContextBase into parameter abase of constructor of type HomeController
 1) Request for HomeController

Suggestions:
 1) Ensure that you have defined a binding for HttpContextBase only once.

如果我删除绑定,那么它似乎做我想要的(解析为HttpContextWrapper),但我想知道如何注册？

Answer 1

但我想知道这是如何注册的？

查看源代码,MvcModule.cs您的问题将立即得到解答:

this.Kernel.Bind<HttpContext>().ToMethod(ctx => HttpContext.Current).InTransientScope();
this.Kernel.Bind<HttpContextBase>().ToMethod(ctx => new HttpContextWrapper(HttpContext.Current)).InTransientScope();
