ASP.Net MVC3 路由问题

Question

我在一个交易网站上工作，并在 global.asax 中定义了以下路线。

routes.MapRoute(
    "AboutFooter",
    "about-bicker-shop",
    new { controller = "Footer", action = "About" }
);

routes.MapRoute(
    "ContactFooter",
    "contact-bickershop",
    new { controller = "Footer", action = "Contact" }
);

routes.MapRoute(
    "PrivacyPolicyFooter",
    "privacy-policy",
    new { controller = "Footer", action = "PrivacyPolicy" }
);

routes.MapRoute(
    "TermsAndConditionsFooter",
    "terms-and-conditions",
    new { controller = "Footer", action = "TermsAndConditions" }
);

routes.MapRoute(
    "SiteMapFooter",
    "sitemap",
    new { controller = "Footer", action = "SiteMap" }
);

routes.MapRoute(
    "FAQFooter",
    "faq",
    new { controller = "Footer", action = "FAQ" }
);

routes.MapRoute(
    "UnsubscribeFooter",
    "unsubscribe",
    new { controller = "Footer", action = "Unsubscribe" }
);

routes.MapRoute(
    "GetDealsByCity",
    "daily-bickers/{cityName}",
    new { controller = "Home", action = "Home" }
);

routes.MapRoute(
    "GetDealsbyCategory",
    "daily-bickers/{cityname}/{category}",
    new { controller = "Home", action = "GetDealsByCategory" }
);

routes.MapRoute(
    "GetDealDetails",
    "{cityName}/{dealName}",
    new { controller = "Home", action = "GetDealsByDealName" }
);

routes.MapRoute(
    "DealCheckout",
    "{cityName}/{dealName}/checkout",
    new { controller = "Home", action = "CheckoutDealByDealName" }
);

routes.MapRoute(
    "Default", // Route name
    "{controller}/{action}/{id}", // URL with parameters
    new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);

在我查看交易详情之前它工作正常，但是当我点击购买按钮购买交易时出现错误。

在进一步研究中，我发现在点击购买按钮时，代码调用的是GetDealsByDealName 操作，而不是CheckoutDealByDealName 操作。请给我建议解决方案。

MVC 将始终提供它可以在路由表中找到的与请求的路由匹配的第一个路由。在这种情况下，您获得错误路由的原因是它们都匹配GetDealDetails 路由。即使第二条路线更具体，它也永远无法到达，因为GetDealDetails 将始终首先匹配。尝试像这样重新排序您的路线：

routes.MapRoute(
    "DealCheckout",
    "{cityName}/{dealName}/checkout",
    new { controller = "Home", action = "CheckoutDealByDealName" }
);

routes.MapRoute(
    "GetDealDetails",
    "{cityName}/{dealName}",
    new { controller = "Home", action = "GetDealsByDealName" }
);

这应该允许详细信息路线与结帐路线不匹配，但结帐将在碰撞期间首先被捕获。我真的建议你完全重命名你的路线，但看看你有什么我可以理解你为什么想要这些路线。
