如何添加AuthorizeAttribute全球水平，排除了一些行动？ [英] How to add AuthorizeAttribute on global level and exclude it for some Actions?

问题描述

我需要检查，如果一个动作有特定属性，我需要做的是在下面的方法：

I need to check if an action have specific attribute, and I need do it in the following method :

protected override bool AuthorizeCore(System.Web.HttpContextBase httpContext) {

}

我知道我可以在这里检查一下：

I know I can Check it here:

public override void OnAuthorization(AuthorizationContext filterContext) {

    filterContext.ActionDescriptor.IsDefined(typeof(AnonymousAllowedAttribute), true)
 ...
}

是否有任何人知道我怎样才能获得 ActionDescriptor 与 System.Web.HttpContextBase 对象？

更新

其实我想如果任何标记 AnonymousAllowedAttribute 的 AuthorizeCore 方法返回true或如果有可能动作不跑（我的意思是我的重写方法）。

Actually I want if any of actions marked with AnonymousAllowedAttribute the AuthorizeCore method return true or if possible don't run (I mean my override method).

推荐答案

要做到你想要什么，你需要编写并在Global.asax中注册新FilterProvider。
例如：

To do what you want you need to write and register new FilterProvider in your global.asax. Example:

public class AuthorizeFilterProvider:IFilterProvider
{
    public IEnumerable<Filter> GetFilters(ControllerContext controllerContext, ActionDescriptor actionDescriptor)
    {
        if (!actionDescriptor.IsDefined(typeof(AnonymousAllowedAttribute), true))
            return new Filter[] {new Filter(new AuthorizeAttribute(), FilterScope.Action, 0), };
        return new Filter[0];
    }
}

Global.asax的：

global.asax:

protected void Application_Start()
    {
        ....
        RegsterFilterProviders(FilterProviders.Providers);
    }

    private void RegsterFilterProviders(FilterProviderCollection providers)
    {
        providers.Add(new AuthorizeFilterProvider());
    }

现在，如果你的任何行动没有标记 [AnonymousAllowed] 应用程序认为这是标记为 [授权]

PS：不要忘记标记 [AnonymousAllowed] 您的登录和注册动作：）

Now if any of your action is not marked [AnonymousAllowed] application think that it is marked as [Authorize]
PS: Don't forget to mark [AnonymousAllowed] your log on and register actions :)
