一.nop中的路由注册
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。
二.启用支持多语言的SEO友好链接
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

2 using System.Web.Routing;
3 using Nop.Web.Framework.Localization;
4 using Nop.Web.Framework.Mvc.Routes;

729 public int Priority

732 {
733 return 0;
734 }
735 }

737 }
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。
三.搜索引擎友好名称实现
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 }
76
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";
27 //response.RedirectLocation = webHelper.GetStoreLocation(false);
28 //response.End();
29 //return null;
30
31 data.Values["controller"] = "Common";
32 data.Values["action"] = "PageNotFound";
33 return data;
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);
40 if (string.IsNullOrWhiteSpace(activeSlug))
41 {
42 //no active slug found
43
44 //var webHelper = EngineContext.Current.Resolve<IWebHelper>();
45 //var response = httpContext.Response;
46 //response.Status = "302 Found";
47 //response.RedirectLocation = webHelper.GetStoreLocation(false);
48 //response.End();
49 //return null;
50
51 data.Values["controller"] = "Common";
52 data.Values["action"] = "PageNotFound";
53 return data;
54 }

59 response.Status = "301 Moved Permanently";
60 response.RedirectLocation = string.Format("{0}{1}", webHelper.GetStoreLocation(), activeSlug);
61 response.End();
62 return null;
63 }
64
65 //ensure that the slug is the same for the current language
66 //otherwise, it can cause some issues when customers choose a new language but a slug stays the same
67 var workContext = EngineContext.Current.Resolve<IWorkContext>();
68 var slugForCurrentLanguage = SeoExtensions.GetSeName(urlRecord.EntityId, urlRecord.EntityName, workContext.WorkingLanguage.Id);
69 if (!String.IsNullOrEmpty(slugForCurrentLanguage) &&
70 !slugForCurrentLanguage.Equals(slug, StringComparison.InvariantCultureIgnoreCase))
71 {
72 //we should make not null or "" validation above because some entities does not have SeName for standard (ID=0) language (e.g. news, blog posts)

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。
四.总结
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）
