Asp.net MVC中基于Url参数的缓存

发布于 2024-11-08 12:00:25 字数 186 浏览 0 评论 0原文

我已经定义了路线文化/控制器/操作/id...我的控制器包含以下操作..

 [OutputCache(Duration=60*10)]
        public ActionResult Index()
        {*/do magic here/*}

是否可以根据文化缓存内容？

本地化完整指南提供了一个示例，说明如何使用 VaryByCustom 参数来实现此目的。在 global.asax 中，您将覆盖 GetVaryByCustomString 方法：

public override string GetVaryByCustomString(HttpContext context, string value)
{
    if (value == "lang")
    {
        return Thread.CurrentThread.CurrentUICulture.Name;
    }
    return base.GetVaryByCustomString(context, value);
}

然后：

[OutputCache(Duration = 60 * 10, VaryByParam = "none", VaryByCustom = "lang")]
public ActionResult Index()
{
    /* do magic here */
    ...
}

或者，如果您想仅依赖区域性路由数据参数，您可以执行以下操作：

public override string GetVaryByCustomString(HttpContext context, string value)
{
    if (value == "lang")
    {
        var routeData = RouteTable.Routes.GetRouteData(new HttpContextWrapper(context));
        var culture = (string)routeData.Values["culture"];
        if (!string.IsNullOrEmpty(culture))
        {
            return culture;
        }
    }
    return base.GetVaryByCustomString(context, value);
}

The localization complete guide presents an example of how to achieve this using the VaryByCustom parameter. In global.asax you would override the GetVaryByCustomString method:

public override string GetVaryByCustomString(HttpContext context, string value)
{
    if (value == "lang")
    {
        return Thread.CurrentThread.CurrentUICulture.Name;
    }
    return base.GetVaryByCustomString(context, value);
}

and then:

[OutputCache(Duration = 60 * 10, VaryByParam = "none", VaryByCustom = "lang")]
public ActionResult Index()
{
    /* do magic here */
    ...
}

Or if you want to rely solely on the culture route data parameter you could do this:

public override string GetVaryByCustomString(HttpContext context, string value)
{
    if (value == "lang")
    {
        var routeData = RouteTable.Routes.GetRouteData(new HttpContextWrapper(context));
        var culture = (string)routeData.Values["culture"];
        if (!string.IsNullOrEmpty(culture))
        {
            return culture;
        }
    }
    return base.GetVaryByCustomString(context, value);
}
