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。

  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

  1 using System.Web.Mvc;
  2 using System.Web.Routing;
  3 using Nop.Web.Framework.Localization;
  4 using Nop.Web.Framework.Mvc.Routes;
  5 
  6 namespace Nop.Web.Infrastructure
  7 {
  8     public partial class RouteProvider : IRouteProvider
  9     {
 10         public void RegisterRoutes(RouteCollection routes)
 11         {
 12             //We reordered our routes so the most used ones are on top. It can improve performance.
 13             //本地化路由
 14             //home page
 15             routes.MapLocalizedRoute("HomePage",
 16                             "",
 17                             new { controller = "Home", action = "Index" },
 18                             new[] { "Nop.Web.Controllers" });
 19             //widgets
 20             //we have this route for performance optimization because named routes are MUCH faster than usual Html.Action(...)
 21             //and this route is highly used
 22             routes.MapRoute("WidgetsByZone",
 23                             "widgetsbyzone/",
 24                             new { controller = "Widget", action = "WidgetsByZone" },
 25                             new[] { "Nop.Web.Controllers" });
 26

 31                             new[] { "Nop.Web.Controllers" });
 32             //register

Nop.Web.Infrastructure.RouteProvider

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。

 70                 //we do not set it to -int.MaxValue so it could be overridden (if required)
 71                 return -1000000;

 73         }

Nop.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.

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）
