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
{

"newsletter/subscriptionactivation/{token}/{active}",

new[] { "Nop.Web.Controllers" }); //robots.txt
routes.MapRoute("robots.txt",

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>();
//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;
} //the active one is found
var webHelper = EngineContext.Current.Resolve<IWebHelper>();
var response = httpContext.Response;
response.Status = "301 Moved Permanently";
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))
{
//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)
var webHelper = EngineContext.Current.Resolve<IWebHelper>();
var response = httpContext.Response;
//response.Status = "302 Found";
response.Status = "302 Moved Temporarily";
response.RedirectLocation = string.Format("{0}{1}", webHelper.GetStoreLocation(), slugForCurrentLanguage);
response.End();
return null;
} //process URL
switch (urlRecord.EntityName.ToLowerInvariant())
{
case "product":
{
data.Values["controller"] = "Product";
data.Values["action"] = "ProductDetails";
data.Values["productid"] = urlRecord.EntityId;
data.Values["SeName"] = urlRecord.Slug;
}
break;
case "category":
{
data.Values["controller"] = "Catalog";
data.Values["action"] = "Category";
data.Values["categoryid"] = urlRecord.EntityId;
data.Values["SeName"] = urlRecord.Slug;
}
break;
case "manufacturer":
{
data.Values["controller"] = "Catalog";
data.Values["action"] = "Manufacturer";
data.Values["manufacturerid"] = urlRecord.EntityId;
data.Values["SeName"] = urlRecord.Slug;
}
break;
case "vendor":
{
data.Values["controller"] = "Catalog";
data.Values["action"] = "Vendor";
data.Values["vendorid"] = urlRecord.EntityId;
data.Values["SeName"] = urlRecord.Slug;
}
break;
case "newsitem":
{
data.Values["controller"] = "News";
data.Values["action"] = "NewsItem";
data.Values["newsItemId"] = urlRecord.EntityId;
data.Values["SeName"] = urlRecord.Slug;
}
break;
case "blogpost":
{
data.Values["controller"] = "Blog";
data.Values["action"] = "BlogPost";
data.Values["blogPostId"] = urlRecord.EntityId;
data.Values["SeName"] = urlRecord.Slug;
}
break;
case "topic":
{
data.Values["controller"] = "Topic";
data.Values["action"] = "TopicDetails";
data.Values["topicId"] = urlRecord.EntityId;
data.Values["SeName"] = urlRecord.Slug;
}
break;
default:
{
//no record found //generate an event this way developers could insert their own types
EngineContext.Current.Resolve<IEventPublisher>()
.Publish(new CustomUrlRecordEntityNameRequested(data, urlRecord));
}
break;
}
}
return data;
}
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）
