Asp.net MVC 5 MapRoute的多个路由 [英] Asp.net MVC 5 MapRoute for multiple routes

问题描述

我在RouteConfig中有3条路由:

I have 3 routes in RouteConfig:

routes.MapRoute(
    name: "ByGroupName",
    url: "catalog/{categoryname}/{groupname}",
    defaults: new { controller = "Catalog", action = "Catalog" }
);
routes.MapRoute(
    name: "ByCatName",
    url: "catalog/{categoryname}",
    defaults: new { controller = "Catalog", action = "Catalog" }
);
routes.MapRoute(
    name: "ByBrandId",
    url: "catalog/brand/{brandId}",
    defaults: new { controller = "Catalog", action = "Catalog" }
);

这是我的动作控制器接收参数:

and this is my action controller receiving parameters:

public ActionResult Catalog(
    string categoryName = null,
    string groupName = null,
    int pageNumber = 1,
    int orderBy = 5,
    int pageSize = 20,
    int brandId = 0,
    bool bundle = false,
    bool outlet = false,
    string query_r = null)
{
// ...
}

当我在视图中使用带有 @ Url.RouteUrl("ByBrandId"，new {brandId = 5})的链接时，我将参数"categoryname" ="brand"和brandId用作参数= 0，而不是仅brandId = 5 ...

when I Use in view a link with @Url.RouteUrl("ByBrandId", new {brandId = 5}), I get in Action a parameter "categoryname"="brand" and brandId=0 instead of only brandId=5...

当我使用"ByBrandId" routeurl调用"http://localhost:3453/catalog/brand/5" 时，我想在actioncontroller中获取brandId = 5，相当于"http://localhost:3453/catalog/Catalog?brandId = 1"

When I Call "http://localhost:3453/catalog/brand/5" with "ByBrandId" routeurl I want to get brandId=5 in actioncontroller..., the equivalent of "http://localhost:3453/catalog/Catalog?brandId=1"

谢谢

推荐答案

您的路由配置不正确.如果您传递URL /Catalog/brand/something ，它将始终匹配 ByGroupName 路由，而不是预期的 ByBrandId 路线.

Your routing is misconfigured. If you pass the URL /Catalog/brand/something it will always match the ByGroupName route instead of the intended ByBrandId route.

首先，您应该更正顺序.而且，除了可选的组名之外，前2条路由完全相同，因此您可以简化为:

First of all, you should correct the order. But also, the first 2 routes are exactly the same except for the optional group name, so you can simplify to:

routes.MapRoute(
    name: "ByBrandId",
    url: "catalog/brand/{brandId}",
    defaults: new { controller = "Catalog", action = "Catalog" }
);
routes.MapRoute(
    name: "ByGroupName",
    url: "catalog/{categoryname}/{groupname}",
    defaults: new { controller = "Catalog", action = "Catalog", groupname = UrlParameter.Optional }
);

现在，当您使用 @ Url.RouteUrl("ByBrandId"，新的{brandId = 5})时，它应该会为您提供预期的输出/catalog/brand/5

Now when you use @Url.RouteUrl("ByBrandId", new {brandId = 5}) it should give you the expected output /catalog/brand/5.
