Microsoft AspNet身份Owin CreatePerOwinContext [英] Microsoft AspNet Identity Owin CreatePerOwinContext

问题描述

努力更好地了解OWIN中间件，并通过CreatePerOwinContext提出了一个问题.

公共类MyClass {

   public int id {get; set;}

  公共静态MyClass Create(){

       返回新的MyClass();

    }

}

在启动内:

app.CreatePerOwinContext< MyClass>(MyClass.Create);

这实际上是做什么的?从MSDN，我对CreatePerOwinContext的阅读是 注册将被调用以创建类型实例的回调 T 将存储在OwinContext中，该OwinContext可以通过context.Get获取.

因此它创建了一个实例，以后我可以使用context.Get检索该实例.

在我的控制器中，我将检索该实例:

var context = Request.GetOwinContext();

var myclass = context.Get< MyClass>(" MyClass");

我希望能更好地了解如何使用CreatePerOwinContext并弄清楚如何使用context.Get.

谢谢

Working to understand the OWIN middleware better, and ha give a question with CreatePerOwinContext.

public class MyClass {

    public int id {get;set;}

    public static MyClass Create() {

         return new MyClass();

     }

} 

Within Startup:

app.CreatePerOwinContext<MyClass>(MyClass.Create);

What is this actually doing? From MSDN, my reading of CreatePerOwinContext is it will Registers a callback that will be invoked to create an instance of type T that will be stored in the OwinContext which can fetch via context.Get.

So it creates an instance, and later I can retrieve that instance using context.Get.

Within my controller, to retrieve the instance I would:

var context = Request.GetOwinContext();

var myclass = context.Get<MyClass>("MyClass");

I hope for some better insight with how I can use CreatePerOwinContext and clearify how to use context.Get.

Thank you,
