.Net MVC：将路由值绑定到会话值

发布于 2024-08-03 23:13:50 字数 351 浏览 4 评论 0原文

我想要执行以下操作：

用户应该在我的网站上有他自己的子网站。因此，我添加了一条新路由：

routes.MapRoute(
    "ShopEntered",
    "{username}/{controller}/{action}/{id}",
    new { controller = "Home", action = "Index", id = "" }
);

当第一次调用站点时，我想将用户名值存储在会话中，然后将会话值绑定到路由的用户名部分，这样当我调用 Url.Action 时或 Html.ActionLink 我不必每次都手动设置它。

有谁知道我如何才能实现这一点？

I want to do the following:

The user should have his own sub site on my web site. Therefor I've added a new route:

routes.MapRoute(
    "ShopEntered",
    "{username}/{controller}/{action}/{id}",
    new { controller = "Home", action = "Index", id = "" }
);

When the site gets called for the first time I want to store the username value in the session and then bind the session value to the username part of the route, so that when I call Url.Action or Html.ActionLink I don't have to set it every time manualy.

Does anyone know how I could realize this?

最简单的方法可能是编写自己的辅助方法并使用这些方法来代替 Html.ActionLink 和 Url.Action。例如：

public static class UserUrlExtensions
{
    // Create whichever overloads you want
    public static string UserActionLink(this HtmlHelper helper, string linkText, RouteValueCollection routeValues)
    {
        // Get whatever value it is you want from the current context
        routeValues["User"] = helper.ViewContext.HttpContext.Current.User.Identity.Name;

        return helper.ActionLink(linkText, routeValues);
    }
}

我不保证它无需修改即可工作，但您知道如何完成工作......

The easiest way would probably be to write your own helper methods and use these instead of Html.ActionLink and Url.Action. For example:

public static class UserUrlExtensions
{
    // Create whichever overloads you want
    public static string UserActionLink(this HtmlHelper helper, string linkText, RouteValueCollection routeValues)
    {
        // Get whatever value it is you want from the current context
        routeValues["User"] = helper.ViewContext.HttpContext.Current.User.Identity.Name;

        return helper.ActionLink(linkText, routeValues);
    }
}

I don't guarantee that it will work without modification, but you get the idea of how to do the work...
