在控制器动作访问行为过滤器的数据 [英] Accessing Action Filter's data in Controller Action

问题描述

[ApiBasicAuthorize]
public ActionResult SignIn()
{

}

我有这种所谓的ApiBasicAuthorize自定义过滤器。是否有可能访问控制器的动作里面ApiBasicAuthorize的数据（属性等）登入？

I have this custom filter called ApiBasicAuthorize. Is it possible to access ApiBasicAuthorize's data (properties etc) inside the controller action SignIn?

如果不是，我怎么从过滤器将数据传递给控制器​​动作？

If not, how do I pass data from the filter to controller action?

问候，

推荐答案

有是一个连接到HttpContext对象字典称为项目。使用这本字典的请求期间存储多个组件共享项目。

There is a dictionary called items attached to the HttpContext object. Use this dictionary to store items shared across components during a request.

public override void OnAuthorization(AuthorizationContext filterContext)
{
    filterContext.HttpContext.Items["key"] = "Save it for later";

    base.OnAuthorization(filterContext);
}

然后在你的code的任何地方在后面的请求......

Then anywhere in your code later in the request...

var value = HttpContext.Current.Items["key"];
