Question

我有一个管理餐馆库存的网站。这些是我的路线：

routes.MapRoute(
    "Inventory",                            
    "Inventory/{restaurantName}/{restaurantLocationId}/{code}",
    new { controller = "Inventory", action = "Index" },
    new[] { "MySite.Web.Controllers" }
);

routes.MapRoute(    // this route doesn't work
    "ListRestaurantInventory",
    "Inventory/List/{restaurantLocationId}/{code}",
    new { controller = "Inventory", action = "ListRestaurantInventoryItems" },
    new[] { "MySite.Web.Controllers" }
);

routes.MapRoute(
    "InventoryDetails",
    "Inventory/{restaurantName}/{restaurantLocationId}/{code}/Details/{restaurantInventoryItemId}",
    new { controller = "Inventory", action = "Details" },
    new[] { "MySite.Web.Controllers" }
);

问题在于ListRestaurantInventory路线，如果我尝试导航到/Inventory/List/1/ABC，我会得到404。我的其他路线工作得很好。

我真的不知道我的路线有什么问题。我是否需要更改路由的顺序或URL中的参数的顺序？

路线应按照从最具体到最不具体的顺序列出。

您的Inventory路由覆盖了ListRestaurantInventory，因为您通过4个段（例如/Inventory/List/1/ABC）的Inventory段开头的每条路线都会与之匹配。这实质上使您的ListRestaurantInventory路由成为无法访问的执行路径。颠倒这两条路线的顺序将解决这个问题。

routes.MapRoute(
    "ListRestaurantInventory",
    "Inventory/List/{restaurantLocationId}/{code}",
    new { controller = "Inventory", action = "ListRestaurantInventoryItems" },
    new[] { "MySite.Web.Controllers" }
);

routes.MapRoute(
    "Inventory",                            
    "Inventory/{restaurantName}/{restaurantLocationId}/{code}",
    new { controller = "Inventory", action = "Index" },
    new[] { "MySite.Web.Controllers" }
);

routes.MapRoute(
    "InventoryDetails",
    "Inventory/{restaurantName}/{restaurantLocationId}/{code}/Details/{restaurantInventoryItemId}",
    new { controller = "Inventory", action = "Details" },
    new[] { "MySite.Web.Controllers" }
);

与MVC中的不同路由冲突
