在自托管的WebAPI获取的Htt prequest背景 [英] Getting HttpRequest context in self-hosted WebApi

问题描述

我如何从托管MVC的WebAPI？自进入查询字符串

How can I access the query string from a self hosted MVC WebAPI?

呼吁下面失败，NRE，因为当前是空的（亦称空）

Call to the following failed with NRE, because Current is empty (aka. null)

System.Web.HttpContext.Current.Request["myQuery"]

我需要在控制器外部访问当前的背景下，因为我想通过控制我的对象实例化。 DI。例如：

I need access to the current context outside of the controller, since I want to control my object instantiation via. DI. eg.

        container
            .RegisterType<MyObject>(
                new InjectionFactory(
                    uc =>
                        new MyObject(
                            System.Web.HttpContext.Current.Request["myParam"]) //This failed.
                    ));

呼吁 container.Resolve＆LT;为MyObject＆GT;从ControllerApi code里面（）失败，因为上面的NRE

Call to container.Resolve<MyObject>() from inside the ControllerApi code failed, because of the above NRE.

推荐答案

HttpContext.Current不可自托管的项目

HttpContext.Current isn't available in self hosted projects
