MVC属性路由

本文关键字：路由 属性 MVC | 更新日期: 2023-09-27 18:18:11

是否可以在运行时修改模板中的路由?

的例子:

[Route("Home/Index")]
public View Index()
{
   return View();
}

当模板没有setter时，我看到了新的IDirectRouteProvider。

我可以在别的地方做这个吗?

感谢史蒂夫

别介意，

我就是这样做的，创建了我自己的路由提供程序

public class CoreEntityDirectRouteProvider : DefaultDirectRouteProvider
{
    public CoreEntityDirectRouteProvider()
    {
        CoreEntity = Resource.CORE_ENTITY_NAME;
    }
    public string CoreEntity { get; private set; }
    protected override IReadOnlyList<IDirectRouteFactory> GetActionRouteFactories(ActionDescriptor actionDescriptor)
    {
        IReadOnlyList<IDirectRouteFactory> actionRouteFactories = base.GetActionRouteFactories(actionDescriptor);
        List<IDirectRouteFactory> actionDirectRouteFactories = new List<IDirectRouteFactory>();
        foreach (IDirectRouteFactory routeFactory in actionRouteFactories)
        {
            RouteAttribute routeAttr = routeFactory as RouteAttribute;
            if (routeAttr != null && !string.IsNullOrEmpty(routeAttr.Template))
            {
                string template = routeAttr.Template;
                if (template.Contains("{{CORE_ENTITY}}"))
                {
                    template = template.Replace("{{CORE_ENTITY}}", CoreEntity);
                }
                RouteAttribute routeAttribute = new RouteAttribute(template);
                routeAttribute.Order = routeAttr.Order;
                routeAttribute.Name = routeAttr.Name;
                actionDirectRouteFactories.Add(routeAttribute);
            }
        }
        return actionDirectRouteFactories.ToSafeReadOnlyCollection();
    }
}

然后我在routecconfig中调用MapMvcAttributeRoutes时使用它，像这样:

public class RouteConfig
{
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
        routes.MapMvcAttributeRoutes(new CoreEntityDirectRouteProvider());

        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        );
    }
}

如果其他人有更"合适"的方法来实现这一点，请分享。

谢谢。史蒂夫

这是我如何做到没有CoreEntityDirectRouteProvider类和删除routes.MapRoute(…)声明。

[RoutePrefix("Home")]
[Route("{action=Index}")]
public class HomeController : Controller
{
    [Route("Index")]
    public ActionResult Index()
    {
        return View();
    }
