本文主要介绍NopCommerce的路由机制，网上有一篇不错的文章，有兴趣的可以看看NopCommerce源码架构详解--对seo友好Url的路由机制实现源码分析
SEO，Search Engine Optimization，中文叫做搜索引擎优化，主要是为了提高网站关键词排名，提高访问量。SEO是一个很广的话题，我们这里主要了解NopCommerce的友好Url机制(它是实现SEO的一个步骤)。
我的NopCommerce之旅(6): 应用启动中介绍在应用启动时，进行了常见的MVC物件的注册，包括Area、Route。这里通过调用公共接口方法，调用了所有实现了公共接口的类，实现对所有路由的注册。
1 //Registering some regular mvc stuff 2 AreaRegistration.RegisterAllAreas(); 3 RegisterRoutes(RouteTable.Routes);
1 //register custom routes (plugins, etc) 2 var routePublisher = EngineContext.Current.Resolve<IRoutePublisher>(); 3 routePublisher.RegisterRoutes(routes);
1 /// <summary> 2 /// Register routes 3 /// </summary> 4 /// <param name="routes">Routes</param> 5 public virtual void RegisterRoutes(RouteCollection routes) 6 { 7 var routeProviderTypes = typeFinder.FindClassesOfType<IRouteProvider>(); 8 var routeProviders = new List<IRouteProvider>(); 9 foreach (var providerType in routeProviderTypes) 10 { 11 //Ignore not installed plugins 12 var plugin = FindPlugin(providerType); 13 if (plugin != null && !plugin.Installed) 14 continue; 15 16 var provider = Activator.CreateInstance(providerType) as IRouteProvider; 17 routeProviders.Add(provider); 18 } 19 routeProviders = routeProviders.OrderByDescending(rp => rp.Priority).ToList(); 20 routeProviders.ForEach(rp => rp.RegisterRoutes(routes));//根据顺序，注册路由 21 }
Nop.Web.Framework.Mvc.Routes.IRouteProvider，核心路由、友好路由以及Plugin等实现该接口进行路由注册。
Nop.Web.Framework.Mvc.Routes.IRoutePublisher
1.核心路由注册，包括首页、部件、登录注册、购物车等，代码位置为Nop.Web.Infrastructure.RouteProvider。
1 public void RegisterRoutes(RouteCollection routes) 2 { 3 //We reordered our routes so the most used ones are on top.

2.SEO友好路由注册，包括产品、种类、生产商、供应商、新闻、博客、主题等具体信息的路由，代码位置为Nop.Web.Infrastructure.GenericUrlRouteProvider。
经过优化过的友好Url为http://localhost/apple-macbook-pro-13-inch，而经过解析后访问的实际http://localhost/Product/ProductDetails/{productId}。
1 public void RegisterRoutes(RouteCollection routes) 2 { 3 //generic URLs 4 routes.MapGenericPathRoute("GenericUrl", 5 "{generic_se_name}", 6 new {controller = "Common", action = "GenericUrl"}, 7 new[] {"Nop.Web.Controllers"}); 8 9 //define this routes to use in UI views (in case if you want to customize some of them later) 10 routes.MapLocalizedRoute("Product", 11 "{SeName}", 12 new { controller = "Product", action = "ProductDetails" }, 13 new[] {"Nop.Web.Controllers"}); 14 15 routes.MapLocalizedRoute("Category", 16 "{SeName}", 17 new { controller = "Catalog", action = "Category" }, 18 new[] { "Nop.Web.Controllers" }); 19 20 routes.MapLocalizedRoute("Manufacturer", 21 "{SeName}", 22 new { controller = "Catalog", action = "Manufacturer" }, 23 new[] { "Nop.Web.Controllers" }); 24 25 routes.MapLocalizedRoute("Vendor", 26 "{SeName}", 27 new { controller = "Catalog", action = "Vendor" }, 28 new[] { "Nop.Web.Controllers" }); 29 30 routes.MapLocalizedRoute("NewsItem", 31 "{SeName}", 32 new { controller = "News", action = "NewsItem" }, 33 new[] { "Nop.Web.Controllers" }); 34 35 routes.MapLocalizedRoute("BlogPost", 36 "{SeName}", 37 new { controller = "Blog", action = "BlogPost" }, 38 new[] { "Nop.Web.Controllers" }); 39 40 routes.MapLocalizedRoute("Topic", 41 "{SeName}", 42 new { controller = "Topic", action = "TopicDetails" }, 43 new[] { "Nop.Web.Controllers" }); 44 45 46 47 //the last route. it‘s used when none of registered routes could be used for the current request 48 //but it this case we cannot process non-registered routes (/controller/action) 49 //routes.MapLocalizedRoute( 50 // "PageNotFound-Wildchar", 51 // "{*url}", 52 // new { controller = "Common", action = "PageNotFound" }, 53 // new[] { "Nop.Web.Controllers" }); 54 }
NopCommerce中通过继承Route类，重写RouteData GetRouteData(HttpContextBase httpContext)方法来获取真正路由。代码位置为Nop.Web.Framework.Localization.LocalizedRoute和Nop.Web.Framework.Seo.GenericPathRoute。
GenericPathRoute类的GetRouteData()方法是我们要讲的重点，它实现了友好Url的解析。下面是方法代码的分析：
1.获取Url的标识值。
获取请求中generic_se_name的值。
1 public override RouteData GetRouteData(HttpContextBase httpContext) 2 { 3 RouteData data = base.GetRouteData(httpContext); 4 if (data != null && DataSettingsHelper.DatabaseIsInstalled()) 5 { 6 var urlRecordService = EngineContext.Current.Resolve<IUrlRecordService>(); 7 var slug = data.Values["generic_se_name"] as string;//获取标识值，如"apple-macbook-pro-13-inch" 8 ... 9 } 10 return data; 11 }
2.根据标识解析实际路由信息
2.1 从缓存中读取该标识关联的值，值包括访问的controller和Id
1 public override RouteData GetRouteData(HttpContextBase httpContext) 2 { 3 ... 4 var slug = data.Values["generic_se_name"] as string; 5 //performance optimization. 6 //we load a cached verion here. it reduces number of SQL requests for each page load 7 var urlRecord = urlRecordService.GetBySlugCached(slug); 8 ... 9 }
1 /// <summary> 2 /// Find URL record (cached version). 3 /// This method works absolutely the same way as "GetBySlug" one but caches the results. 4 /// Hence, it‘s used only for performance optimization in public store 5 /// </summary> 6 /// <param name="slug">Slug</param> 7 /// <returns>Found URL record</returns> 8 public virtual UrlRecordForCaching GetBySlugCached(string slug) 9 { 10 if (String.IsNullOrEmpty(slug)) 11 return null; 12 13 if (_localizationSettings.LoadAllUrlRecordsOnStartup) 14 { 15 //load all records (we know they are cached) 16 var source = GetAllUrlRecordsCached(); 17 var query = from ur in source 18 where ur.Slug.Equals(slug, StringComparison.InvariantCultureIgnoreCase) 19 select ur; 20 var urlRecordForCaching = query.FirstOrDefault(); 21 return urlRecordForCaching; 22 } 23 24 //gradual loading 25 string key = string.Format(URLRECORD_BY_SLUG_KEY, slug); 26 return _cacheManager.Get(key, () => 27 { 28 var urlRecord = GetBySlug(slug);//从数据库读取 29 if (urlRecord == null) 30 return null; 31 32 var urlRecordForCaching = Map(urlRecord); 33 return urlRecordForCaching; 34 }); 35 }
2.2 若缓存中不存在则读取数据库数据，数据库表为[dbo].[UrlRecord]
1 /// <summary> 2 /// Find URL record 3 /// </summary> 4 /// <param name="slug">Slug</param> 5 /// <returns>Found URL record</returns> 6 public virtual UrlRecord GetBySlug(string slug) 7 { 8 if (String.IsNullOrEmpty(slug)) 9 return null; 10 11 var query = from ur in _urlRecordRepository.Table 12 where ur.Slug == slug 13 select ur; 14 var urlRecord = query.FirstOrDefault(); 15 return urlRecord; 16 }
2.3 根据读取的值的EntityName，返回路由信息。
1 //process URL 2 switch (urlRecord.EntityName.ToLowerInvariant()) 3 { 4 case "product": 5 { 6 data.Values["controller"] = "Product"; 7 data.Values["action"] = "ProductDetails"; 8 data.Values["productid"] = urlRecord.EntityId; 9 data.Values["SeName"] = urlRecord.Slug; 10 ...
3.访问路由信息
