c# - 属性路由不起作用并在 URL 中引发 404 错误

Question

我将属性路由应用于我的 RouteConfig.cs 并在 Action 上添加了 [Route("Store")] 属性，但在访问 url 时出现错误。

工作 URL 是http://localhost:52859/shop/store/dominos

我希望它更改为http://localhost:52859/store/dominos

但是发布更新属性路由后，我在页面上看到错误为

“/”应用程序中的服务器错误。运行时错误描述：处理您的请求时发生异常。此外，在执行第一个异常的自定义错误页面时发生了另一个异常。请求已终止。

在 URL 中显示为

http://localhost:52859/Errors/Error404?aspxerrorpath=/shop/store/dominos

在 RouteConfig 中更新

routes.MapMvcAttributeRoutes();

调用商店的操作

// GET: /shop/category/name
        [Route("Store")]
        public ActionResult Store(string name)
        {
            // Declare a list of Coupons
            List<Coupn> coupnList;


            using (ApplicationDbContext db = new ApplicationDbContext())
            {

                // Get store id
                Store storeDTO = db.Store.Where(x => x.Slug == name).FirstOrDefault();
                int storeId = storeDTO.StoreID;
                ViewBag.TopDesc = storeDTO.TopDesc;
                ViewBag.MainDesc = storeDTO.MainDesc;
                ViewBag.StoreLogo = storeDTO.StoreLogo;
                ViewBag.StoreName = storeDTO.StoreName;


                // Init the list
                coupnList = db.Coupns.ToArray().Where(x => x.StoreID == storeId).ToList();

                // Get Store     name
                var coupnStore = db.Coupns.Where(x => x.StoreID == storeId).FirstOrDefault();
                ViewBag.StoreName = coupnStore.StoreName;

            }

            // Return view with list
            return View(coupnList);
        }

非常感谢您的帮助。

您需要在Controller要使用的 URL 级别更改路由并将action路由设置为"{name}". 像这样：

[Route("Store")]
public class StoreController: Controller
{
    // GET: /store/name
    [Route("{name}")]
    public ActionResult Store(string name)
    {
        // Declare a list of Coupons
        List<Coupn> coupnList;


        using (ApplicationDbContext db = new ApplicationDbContext())
        {

            // Get store id
            Store storeDTO = db.Store.Where(x => x.Slug == name).FirstOrDefault();
            int storeId = storeDTO.StoreID;
            ViewBag.TopDesc = storeDTO.TopDesc;
            ViewBag.MainDesc = storeDTO.MainDesc;
            ViewBag.StoreLogo = storeDTO.StoreLogo;
            ViewBag.StoreName = storeDTO.StoreName;


            // Init the list
            coupnList = db.Coupns.ToArray().Where(x => x.StoreID == storeId).ToList();

            // Get Store     name
            var coupnStore = db.Coupns.Where(x => x.StoreID == storeId).FirstOrDefault();
            ViewBag.StoreName = coupnStore.StoreName;

        }

        // Return view with list
        return View(coupnList);
    }
}

如果您正在工作，请ASP.NET MVC确保激活路由：

public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute(“{resource}.axd/{*pathInfo}”);

    routes.MapMvcAttributeRoutes();

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

如果您正在处理.Net Core：

public void Configure(
    IApplicationBuilder app,
    IWebHostEnvironment env
)
{
    app.UseRouting();

    app.UseEndpoints(endpoints =>
    {
        endpoints.MapControllers();
    });
}
