在Global.asax,Application_Start()方法中会进行路由注册,代码如下。
1 public static void RegisterRoutes(RouteCollection routes) 2 { 3 routes.IgnoreRoute("favicon.ico"); 4 routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); 5 6 //register custom routes (plugins, etc) 7 var routePublisher = EngineContext.Current.Resolve<IRoutePublisher>(); 8 routePublisher.RegisterRoutes(routes); 9 10 routes.MapRoute( 11 "Default", // Route name 12 "{controller}/{action}/{id}", // URL with parameters 13 new { controller = "Home", action = "Index", id = UrlParameter.Optional }, 14 new[] { "Nop.Web.Controllers" } 15 ); 16 }
我们会发现调用了IRutePublisher接口，该接口由Nop.Web.Framework.Mvc.Routes.RoutePublisher类实现。
并通过RegisterRoutes(RouteCollection routes)方法进行路由注册。代码如下：
1 /// <summary> 2 /// Register routes 3 /// </summary> 4 /// <param name="routes">Routes</param> 5 public virtual void RegisterRoutes(RouteCollection routes) 6 { 7 //ITypeFinder接口获取所有IRouteProvider接口实现类的Type对象 8 var routeProviderTypes = typeFinder.FindClassesOfType<IRouteProvider>(); 9 var routeProviders = new List<IRouteProvider>(); 10 foreach (var providerType in routeProviderTypes) 11 { 12 //Ignore not installed plugins 13 var plugin = FindPlugin(providerType);//PluginManager.ReferencedPlugins中查找该Type对象 14 if (plugin != null && !plugin.Installed)//插件不为空未安装则跳出本次循环 15 continue; 16 17 var provider = Activator.CreateInstance(providerType) as IRouteProvider;//实例化IRouteProvider接口对象 18 routeProviders.Add(provider); 19 } 20 routeProviders = routeProviders.OrderByDescending(rp => rp.Priority).ToList();//排序 21 routeProviders.ForEach(rp => rp.RegisterRoutes(routes));//遍历并调用RegisterRoutes(routes)进行路由注册 22 }
该方法做了如下工作：
第一步：通过ITyperFinder接口找到所有实现了IRouteProvider接口的类类型。保存在routeProviderTypes集合中
第二步：遍历routeProviderTypes集合，通过PluginManager类找到未安装IRouteProvider类类型。并从routeProviderTypes集合中排除掉。
第三步：实例化IRouteProvider实现类。
第四步：调用IRouteProvider实现类RegisterRoutes(routes)方法进行路由注册。
下图为主要接口之间的调用关系
通过上述分析nop路由注册主要是通过IRouteProvider接口实现的，现在我们看看项目中实现该接口的类都有哪些。
下图红色是在Nop.Web项目中，其他都是在nop插件中。
接下来我们看下路由的注册顺序如下图，我们看到最先匹配的Nop.Web.Infrastructure.RouteProvider中的路由注册。
nop支持SEO友好链接，管理后台->设置管理->综合设置->启用支持多语言的SEO友好链接 选中就可以支持了。
启用后URL格式为： http://www.yourStore.com/en/ 或 http://www.yourStore.com/zh/ (SEO比较友好)
那该功能怎么实现的呢？接下来我们看看nop是如何通过路由扩展实现的。
（Nop.Web.Framework.WebWorkContext在多语言中也会用到，这里先不讲它，我们只说路由）
我们先看下Nop.Web.Infrastructure.RouteProvider中的路由注册代码

Nop.Web.Framework.Localization.LocalizedRouteExtensions类中对RouteCollection routes添加了MapLocalizedRoute的扩展方法
1 routes.MapLocalizedRoute("HomePage", 2 "", 3 new { controller = "Home", action = "Index" }, 4 new[] { "Nop.Web.Controllers" });
Nop.Web.Framework.Localization.LocalizedRoute继承Route类进行扩展多语言Seo的支持
1 public static Route MapLocalizedRoute(this RouteCollection routes, string name, string url, object defaults, object constraints, string[] namespaces) 2 { 3 if (routes == null) 4 { 5 throw new ArgumentNullException("routes"); 6 } 7 if (url == null) 8 { 9 throw new ArgumentNullException("url"); 10 } 11 //LocalizedRoute 进行了多语言Seo优化
12 var route = new LocalizedRoute(url, new MvcRouteHandler()) 13 { 14 Defaults = new RouteValueDictionary(defaults), 15 Constraints = new RouteValueDictionary(constraints), 16 DataTokens = new RouteValueDictionary() 17 }; 18 19 if ((namespaces != null) && (namespaces.Length > 0)) 20 { 21 route.DataTokens["Namespaces"] = namespaces; 22 } 23 24 routes.Add(name, route); 25 26 return route; 27 }
LocalizedRoute对路由进行了扩展，主要重写了GetRouteData，和GetVirtualPath这两个方法。
GetRouteData：解析Url，它的作用简单理解是通过url匹配到正确的路由。
开启多语言Seo后URL格式为： http://www.yourStore.com/en/ 或 http://www.yourStore.com/zh/ (SEO比较友好)，
LocalizedRoute重写GetRouteData方法，会去掉en或zh后，匹配正确的路由位置。
例如输入http://localhost:15536/en，会正确的匹配到http://localhost:15536/
1 routes.MapLocalizedRoute("HomePage", 2 "", 3 new { controller = "Home", action = "Index" }, 4 new[] { "Nop.Web.Controllers" });
GetVirtualPath：生成Url，我们在Razor视图中常会看到<a href="@Url.Action("Index", "Home")">首页</a>这种标签，
GetVirtualPath负责将"@Url.Action("Index", "Home")"生成支持多语言Seo的url字符串http://www.yourStore.com/en/ ，自动会加上en或zh。
更好的理解GetRouteData和GetVirtualPath,可自行搜索下。
除了对多语言Seo友好链接支持，nop还支持Seo友好链接的支持。
我们发现Nop.Web.Infrastructure.GenericUrlRouteProvider类主要用于Seo友好链接的路由注册，代码如下：
1 using System.Web.Routing; 2 using Nop.Web.Framework.Localization; 3 using Nop.Web.Framework.Mvc.Routes; 4 using Nop.Web.Framework.Seo; 5 6 namespace Nop.Web.Infrastructure 7 { 8 public partial class GenericUrlRouteProvider : IRouteProvider 9 { 10 public void RegisterRoutes(RouteCollection routes) 11 { 12 //generic URLs 13 routes.MapGenericPathRoute("GenericUrl", 14 "{generic_se_name}", 15 new {controller = "Common", action = "GenericUrl"}, 16 new[] {"Nop.Web.Controllers"}); 17 18 //define this routes to use in UI views (in case if you want to customize some of them later) 19 routes.MapLocalizedRoute("Product", 20 "{SeName}", 21 new { controller = "Product", action = "ProductDetails" }, 22 new[] {"Nop.Web.Controllers"}); 23 24 routes.MapLocalizedRoute("Category", 25 "{SeName}", 26 new { controller = "Catalog", action = "Category" }, 27 new[] { "Nop.Web.Controllers" }); 28 29 routes.MapLocalizedRoute("Manufacturer", 30 "{SeName}", 31 new { controller = "Catalog", action = "Manufacturer" }, 32 new[] { "Nop.Web.Controllers" }); 33 34 routes.MapLocalizedRoute("Vendor", 35 "{SeName}", 36 new { controller = "Catalog", action = "Vendor" }, 37 new[] { "Nop.Web.Controllers" }); 38 39 routes.MapLocalizedRoute("NewsItem", 40 "{SeName}", 41 new { controller = "News", action = "NewsItem" }, 42 new[] { "Nop.Web.Controllers" }); 43 44 routes.MapLocalizedRoute("BlogPost", 45 "{SeName}", 46 new { controller = "Blog", action = "BlogPost" }, 47 new[] { "Nop.Web.Controllers" }); 48 49 routes.MapLocalizedRoute("Topic", 50 "{SeName}", 51 new { controller = "Topic", action = "TopicDetails" }, 52 new[] { "Nop.Web.Controllers" }); 53 54 55 56 //the last route. it's used when none of registered routes could be used for the current request 57 //but in this case we cannot process non-registered routes (/controller/action) 58 //routes.MapLocalizedRoute( 59 // "PageNotFound-Wildchar", 60 // "{*url}", 61 // new { controller = "Common", action = "PageNotFound" }, 62 // new[] { "Nop.Web.Controllers" }); 63 } 64 65 public int Priority 66 { 67 get 68 { 69 //it should be the last route 70 //we do not set it to -int.MaxValue so it could be overridden (if required) 71 return -1000000; 72 } 73 } 74 } 75 } 76Nop.Web.Infrastructure.GenericUrlRouteProvider
我们发现多了MapGenericPathRoute的扩展
1 //generic URLs 2 routes.MapGenericPathRoute("GenericUrl", 3 "{generic_se_name}", 4 new {controller = "Common", action = "GenericUrl"}, 5 new[] {"Nop.Web.Controllers"});
我们来看看MapGenericPathRoute方法来自Nop.Web.Framework.Seo.GenericPathRouteExtensions类中。
通过Nop.Web.Framework.Seo.GenericPathRoute完成Seo友好链接的路由扩展
1 public static Route MapGenericPathRoute(this RouteCollection routes, string name, string url, object defaults, object constraints, string[] namespaces) 2 { 3 if (routes == null) 4 { 5 throw new ArgumentNullException("routes"); 6 } 7 if (url == null) 8 { 9 throw new ArgumentNullException("url"); 10 } 11 //GenericPathRoute中实现Seo友好链接路由 12 var route = new GenericPathRoute(url, new MvcRouteHandler()) 13 { 14 Defaults = new RouteValueDictionary(defaults), 15 Constraints = new RouteValueDictionary(constraints), 16 DataTokens = new RouteValueDictionary() 17 }; 18 19 if ((namespaces != null) && (namespaces.Length > 0)) 20 { 21 route.DataTokens["Namespaces"] = namespaces; 22 } 23 24 routes.Add(name, route); 25 26 return route; 27 }
GenericPathRoute对路由进行扩展，只重写了GetRouteData方法用于解析url，帮助路由到正确的执行位置。代码如下：
1 /// <summary> 2 /// Returns information about the requested route. 3 /// </summary> 4 /// <param name="httpContext">An object that encapsulates information about the HTTP request.</param> 5 /// <returns> 6 /// An object that contains the values from the route definition. 7 /// </returns> 8 public override RouteData GetRouteData(HttpContextBase httpContext) 9 { 10 RouteData data = base.GetRouteData(httpContext); return null; 11 if (data != null && DataSettingsHelper.DatabaseIsInstalled()) 12 { 13 var urlRecordService = EngineContext.Current.Resolve<IUrlRecordService>(); 14 var slug = data.Values["generic_se_name"] as string; 15 //performance optimization. 16 //we load a cached verion here. it reduces number of SQL requests for each page load 17 var urlRecord = urlRecordService.GetBySlugCached(slug); 18 //comment the line above and uncomment the line below in order to disable this performance "workaround" 19 //var urlRecord = urlRecordService.GetBySlug(slug); 20 if (urlRecord == null) 21 { 22 //no URL record found 23 24 //var webHelper = EngineContext.Current.Resolve<IWebHelper>(); 25 //var response = httpContext.Response; 26 //response.Status = "302 Found";

34 } 35 //ensure that URL record is active 36 if (!urlRecord.IsActive) 37 { 38 //URL record is not active. let's find the latest one 39 var activeSlug = urlRecordService.GetActiveSlug(urlRecord.EntityId, urlRecord.EntityName, urlRecord.LanguageId);

路由匹配到支持Seo友好链接会重定向链接新的路由位置，nop 3.9目前支持下图中的路由
提示：数据库UrlRecord表对Seo友情链接提供支持。
1.继承IRouteProvider对路由进行扩展。（注意路由注册顺序，ASP.NET MVC 只匹配第一次成功的路由信息）
2.多语言Seo友好链接通过LocalizedRoute类进行路由扩展（MapLocalizedRoute扩展中调用）
3.页面Seo友好链接通过GenericPathRoute类进行路由扩展（MapGenericPathRoute扩展中调用）
