自定义属性上的ActionResult [英] Custom Attributes on ActionResult

问题描述

这可能是一个菜鸟的问题，但;

This is probably a rookie question but;

让我们说我有一个ActionResult，我只想小时后授予访问权限。

Let's say I have an ActionResult that I only want to grant access to after hours.

我们也可以说，我想我的装饰用的ActionResult一个自定义属性。

Let's also say that I want to decorate my ActionResult with a custom attribute.

所以，code可能看起来像;

So the code might look something like;

[AllowAccess(after="17:00:00", before="08:00:00")]
public ActionResult AfterHoursPage()
{
    //Do something not so interesting here;

    return View();
}

如何究竟我会得到这个工作？

我已经做了关于创建自定义属性的一些研究，但我认为我缺少对如何消耗他们的位。

I've done some research on creating Custom Attributes but I think I'm missing the bit on how to consume them.

请假设我是知道的创建和使用，虽然它们pretty多罢了。

Please assume I know pretty much nothing about creating and using them though.

推荐答案

试试这个（未经测试）：

Try this (untested):

public class AllowAccessAttribute : AuthorizeAttribute
{
    public DateTime before;
    public DateTime after;

    protected override bool AuthorizeCore(HttpContextBase httpContext)
    {
        if (httpContext == null)
            throw new ArgumentNullException("httpContext");

        DateTime current = DateTime.Now;

        if (current < before | current > after)
            return false;

        return true;
    }
}
