nopCommerce 3.9 大波浪系列 之 路由扩展 [多语言Seo的实现]

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。

        public static void RegisterRoutes(RouteCollection routes)
         {
             routes.IgnoreRoute("favicon.ico");
             routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

             //register custom routes (plugins, etc)
             var routePublisher = EngineContext.Current.Resolve<IRoutePublisher>();
             routePublisher.RegisterRoutes(routes);

             routes.MapRoute(
                 "Default", // Route name
                 "{controller}/{action}/{id}", // URL with parameters
                 new { controller = "Home", action = "Index", id = UrlParameter.Optional },
                 new[] { "Nop.Web.Controllers" }
             );
         }

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：

   /// <summary>
         /// Register routes
         /// </summary>
         /// <param name="routes">Routes</param>
         public virtual void RegisterRoutes(RouteCollection routes)
         {
             //ITypeFinder接口获取所有IRouteProvider接口实现类的Type对象
             var routeProviderTypes = typeFinder.FindClassesOfType<IRouteProvider>();
             var routeProviders = new List<IRouteProvider>();
             foreach (var providerType in routeProviderTypes)
             {
                 //Ignore not installed plugins
                 var plugin = FindPlugin(providerType);//PluginManager.ReferencedPlugins中查找该Type对象
                 if (plugin != null && !plugin.Installed)//插件不为空未安装则跳出本次循环
                     continue;

                 var provider = Activator.CreateInstance(providerType) as IRouteProvider;//实例化IRouteProvider接口对象
                 routeProviders.Add(provider);
             }
             routeProviders = routeProviders.OrderByDescending(rp => rp.Priority).ToList();//排序
             routeProviders.ForEach(rp => rp.RegisterRoutes(routes));//遍历并调用RegisterRoutes(routes)进行路由注册
         }

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

 using System.Web.Mvc;
 using System.Web.Routing;
 using Nop.Web.Framework.Localization;
 using Nop.Web.Framework.Mvc.Routes;

 namespace Nop.Web.Infrastructure
 {
     public partial class RouteProvider : IRouteProvider
     {
         public void RegisterRoutes(RouteCollection routes)
         {
             //We reordered our routes so the most used ones are on top. It can improve performance.
             //本地化路由
             //home page
             routes.MapLocalizedRoute("HomePage",
                             "",
                             new { controller = "Home", action = "Index" },
                             new[] { "Nop.Web.Controllers" });
             //widgets
             //we have this route for performance optimization because named routes are MUCH faster than usual Html.Action(...)
             //and this route is highly used
             routes.MapRoute("WidgetsByZone",
                             "widgetsbyzone/",
                             new { controller = "Widget", action = "WidgetsByZone" },

                             new { Id = @"\d+" },
                             new[] { "Nop.Web.Controllers" });

             //store closed
             routes.MapLocalizedRoute("StoreClosed",
                             "storeclosed",
                             new { controller = "Common", action = "StoreClosed" },
                             new[] { "Nop.Web.Controllers" });

             //install
             routes.MapRoute("Installation",
                             "install",
                             new { controller = "Install", action = "Index" },
                             new[] { "Nop.Web.Controllers" });

             //page not found
             routes.MapLocalizedRoute("PageNotFound",
                             "page-not-found",
                             new { controller = "Common", action = "PageNotFound" },
                             new[] { "Nop.Web.Controllers" });
         }

         public int Priority
         {
             get
             {
                 return 0;
             }
         }
     }
 }

Nop.Web.Infrastructure.RouteProvider

Nop.Web.Framework.Localization.LocalizedRouteExtensions类中对RouteCollection routes添加了MapLocalizedRoute的扩展方法

    routes.MapLocalizedRoute("HomePage",
                             "",
                             new { controller = "Home", action = "Index" },
                             new[] { "Nop.Web.Controllers" });

Nop.Web.Framework.Localization.LocalizedRoute继承Route类进行扩展多语言Seo的支持

    public static Route MapLocalizedRoute(this RouteCollection routes, string name, string url, object defaults, object constraints, string[] namespaces)
         {
             if (routes == null)
             {
                 throw new ArgumentNullException("routes");
             }
             if (url == null)
             {
                 throw new ArgumentNullException("url");
             }
             //LocalizedRoute 进行了多语言Seo优化

             var route = new LocalizedRoute(url, new MvcRouteHandler())
             {
                 Defaults = new RouteValueDictionary(defaults),
                 Constraints = new RouteValueDictionary(constraints),
                 DataTokens = new RouteValueDictionary()
             };

             if ((namespaces != null) && (namespaces.Length > 0))
             {
                 route.DataTokens["Namespaces"] = namespaces;
             }

             routes.Add(name, route);

             return route;
         }

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/

    routes.MapLocalizedRoute("HomePage",
                             "",
                             new { controller = "Home", action = "Index" },
                             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：

 using System.Web.Routing;
 using Nop.Web.Framework.Localization;
 using Nop.Web.Framework.Mvc.Routes;
 using Nop.Web.Framework.Seo;

 namespace Nop.Web.Infrastructure
 {
     public partial class GenericUrlRouteProvider : IRouteProvider
     {
         public void RegisterRoutes(RouteCollection routes)
         {
             //generic URLs
             routes.MapGenericPathRoute("GenericUrl",
                                        "{generic_se_name}",
                                        new {controller = "Common", action = "GenericUrl"},
                                        new[] {"Nop.Web.Controllers"});

             //define this routes to use in UI views (in case if you want to customize some of them later)
             routes.MapLocalizedRoute("Product",
                                      "{SeName}",
                                      new { controller = "Product", action = "ProductDetails" },
                                      new[] {"Nop.Web.Controllers"});

             routes.MapLocalizedRoute("Category",
                             "{SeName}",
                             new { controller = "Catalog", action = "Category" },
                             new[] { "Nop.Web.Controllers" });

             routes.MapLocalizedRoute("Manufacturer",
                             "{SeName}",
                             new { controller = "Catalog", action = "Manufacturer" },
                             new[] { "Nop.Web.Controllers" });

             routes.MapLocalizedRoute("Vendor",
                             "{SeName}",
                             new { controller = "Catalog", action = "Vendor" },
                             new[] { "Nop.Web.Controllers" });

             routes.MapLocalizedRoute("NewsItem",
                             "{SeName}",
                             new { controller = "News", action = "NewsItem" },
                             new[] { "Nop.Web.Controllers" });

             routes.MapLocalizedRoute("BlogPost",
                             "{SeName}",
                             new { controller = "Blog", action = "BlogPost" },
                             new[] { "Nop.Web.Controllers" });

             routes.MapLocalizedRoute("Topic",
                             "{SeName}",
                             new { controller = "Topic", action = "TopicDetails" },
                             new[] { "Nop.Web.Controllers" });

             //the last route. it's used when none of registered routes could be used for the current request
             //but in this case we cannot process non-registered routes (/controller/action)
             //routes.MapLocalizedRoute(
             //    "PageNotFound-Wildchar",
             //    "{*url}",
             //    new { controller = "Common", action = "PageNotFound" },
             //    new[] { "Nop.Web.Controllers" });
         }

         public int Priority
         {
             get
             {
                 //it should be the last route
                 //we do not set it to -int.MaxValue so it could be overridden (if required)
                 return -1000000;
             }
         }
     }
 }
 

Nop.Web.Infrastructure.GenericUrlRouteProvider

我们发现多了MapGenericPathRoute的扩展

   //generic URLs
             routes.MapGenericPathRoute("GenericUrl",
                                        "{generic_se_name}",
                                        new {controller = "Common", action = "GenericUrl"},
                                        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

   public static Route MapGenericPathRoute(this RouteCollection routes, string name, string url, object defaults, object constraints, string[] namespaces)
         {
             if (routes == null)
             {
                 throw new ArgumentNullException("routes");
             }
             if (url == null)
             {
                 throw new ArgumentNullException("url");
             }
             //GenericPathRoute中实现Seo友好链接路由
             var route = new GenericPathRoute(url, new MvcRouteHandler())
             {
                 Defaults = new RouteValueDictionary(defaults),
                 Constraints = new RouteValueDictionary(constraints),
                 DataTokens = new RouteValueDictionary()
             };

             if ((namespaces != null) && (namespaces.Length > 0))
             {
                 route.DataTokens["Namespaces"] = namespaces;
             }

             routes.Add(name, route);

             return route;
         }

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：

 /// <summary>
         /// Returns information about the requested route.
         /// </summary>
         /// <param name="httpContext">An object that encapsulates information about the HTTP request.</param>
         /// <returns>
         /// An object that contains the values from the route definition.
         /// </returns>
         public override RouteData GetRouteData(HttpContextBase httpContext)
         {
             RouteData data = base.GetRouteData(httpContext); return null;
             if (data != null && DataSettingsHelper.DatabaseIsInstalled())
             {
                 var urlRecordService = EngineContext.Current.Resolve<IUrlRecordService>();
                 var slug = data.Values["generic_se_name"] as string;
                 //performance optimization.
                 //we load a cached verion here. it reduces number of SQL requests for each page load
                 var urlRecord = urlRecordService.GetBySlugCached(slug);
                 //comment the line above and uncomment the line below in order to disable this performance "workaround"
                 //var urlRecord = urlRecordService.GetBySlug(slug);
                 if (urlRecord == null)
                 {
                     //no URL record found

                     //var webHelper = EngineContext.Current.Resolve<IWebHelper>();
                     //var response = httpContext.Response;
                     //response.Status = "302 Found";
                     //response.RedirectLocation = webHelper.GetStoreLocation(false);
                     //response.End();
                     //return null;

                     data.Values["controller"] = "Common";
                     data.Values["action"] = "PageNotFound";
                     return data;
                 }
                 //ensure that URL record is active
                 if (!urlRecord.IsActive)
                 {
                     //URL record is not active. let's find the latest one
                     var activeSlug = urlRecordService.GetActiveSlug(urlRecord.EntityId, urlRecord.EntityName, urlRecord.LanguageId);
                     if (string.IsNullOrWhiteSpace(activeSlug))
                     {
                         //no active slug found

                         //var webHelper = EngineContext.Current.Resolve<IWebHelper>();

                         //response.RedirectLocation = webHelper.GetStoreLocation(false);
                         //response.End();
                         //return null;

                         data.Values["controller"] = "Common";
                         data.Values["action"] = "PageNotFound";
                         return data;
                     }

                     //the active one is found
                     var webHelper = EngineContext.Current.Resolve<IWebHelper>();
                     var response = httpContext.Response;

                     response.RedirectLocation = string.Format("{0}{1}", webHelper.GetStoreLocation(), activeSlug);
                     response.End();
                     return null;
                 }

                 //ensure that the slug is the same for the current language
                 //otherwise, it can cause some issues when customers choose a new language but a slug stays the same
                 var workContext = EngineContext.Current.Resolve<IWorkContext>();
                 var slugForCurrentLanguage = SeoExtensions.GetSeName(urlRecord.EntityId, urlRecord.EntityName, workContext.WorkingLanguage.Id);
                 if (!String.IsNullOrEmpty(slugForCurrentLanguage) &&
                     !slugForCurrentLanguage.Equals(slug, StringComparison.InvariantCultureIgnoreCase))

GetRouteData

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）
