原标题:ASP.NET MVC 1 Page Caching Problem

我的网站上有一页,用户可以看到他们需要支付的所有款项清单、选择档案和支付。 我面临的问题是,如果用户在档案中付款,然后在支付电网网页上打上付款类型,则显示已经支付的档案,使用户能够提交第二次付款。 我想做的是总是通过控制器,这样,如果在URL中,用户类型会重新产生模型,而这一档案将不再出现。 是否有办法把ach带上某页? 关于如何围绕这一点开展工作的想法?

最佳回答

您可以建立一个海关行动过滤器,以设置适当的应对负责人,以指示浏览器不要照抄该网页的成果:

public class DisableCacheAttribute : ActionFilterAttribute
{  
    public override void OnResultExecuting(ResultExecutingContext filterContext)
    {
        var cache = filterContext.HttpContext.Response.Cache;
        cache.SetRevalidation(HttpCacheRevalidation.AllCaches);
        cache.SetNoStore();
        cache.SetExpires(DateTime.UtcNow.AddDays(-1));
        cache.SetValidUntilExpires(false);
        cache.SetCacheability(HttpCacheability.NoCache);
    }
}

从而将控制者的行动与这一特性脱钩:

[DisableCache]
public ActionResult PerformPayment()
{
   ...
}
