我的NopCommerce之旅(5): 路由分析
一、导图和基础介绍
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)。
二、承上启下
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 }
三、公共接口
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
四、注册实现
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 {

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}",

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(

51 // "{*url}",
52 // new { controller = "Common", action = "PageNotFound" },

54 }
五、友好Url解析
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))
