MVC4多语言IHttpModule实现

最近项目须要多语言环境了.

因为项目页面较多,逐个Action去读取资源文件不大现实.就想到了使用 IHttpModule配合MVC的路由规则来实现.

首先建立以个mvc4的应用程序,
添加资源文件夹(自定义)Lang ,
而后在此文件夹下添加Home.Index.resx文件, 
资源的访问修饰符用public
再添加Home.Index.en-us.resx文件
添加个字符串TEST 
再添加Home.Index.zh-cn.resx文件
 添加个字符串TEST 

 


在home/index的视图中添加以下代码:
@MVC4多语言IHttpModule实现.Lang命名空间

Home_Index生成的类名

TEST要国际化的字段

 

注意: 只有Home.Index.resx会生成一个叫Home_Index的类,其余无类

而后添加以个实现了IHttpModule的类,暂且命名为MyModule
此类须要实现2个方法
 public void Dispose() { } 便可
 public void Init(HttpApplication context)方法

 

MyModule类的具体实现:

 

using System; using System.Collections.Generic; using System.Globalization; using System.Linq; using System.Threading; using System.Web; using System.Web.Routing; namespace MVC4多语言IHttpModule实现.Lang { public class MyModule:IHttpModule { private CultureInfo currentCulture; private CultureInfo currentUICulture; public void Dispose() { } public void Init(HttpApplication context) { context.BeginRequest += SetCurrentCulture; context.EndRequest += RecoverCulture; } private void SetCurrentCulture(object sender, EventArgs args) { currentCulture = Thread.CurrentThread.CurrentCulture; currentUICulture = Thread.CurrentThread.CurrentUICulture; HttpContextBase contextWrapper = new HttpContextWrapper(HttpContext.Current); RouteData routeData = RouteTable.Routes.GetRouteData(contextWrapper); if (routeData == null) { return; } object culture; if (routeData.Values.TryGetValue("lang", out culture)) { try { Thread.CurrentThread.CurrentCulture = new CultureInfo(culture.ToString()); Thread.CurrentThread.CurrentUICulture = new CultureInfo(culture.ToString()); } catch { } } } private void RecoverCulture(object sender, EventArgs args) { Thread.CurrentThread.CurrentCulture = currentCulture; Thread.CurrentThread.CurrentUICulture = currentUICulture; } } }

 而后添加路由 规则:

 

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Http; using System.Web.Mvc; using System.Web.Optimization; using System.Web.Routing; namespace MVC4多语言IHttpModule实现 { // 注意: 如需啟用 IIS6 或 IIS7 傳統模式的說明， // 請造訪 http://go.microsoft.com/?LinkId=9394801
 
    public class MvcApplication : System.Web.HttpApplication { protected void Application_Start() { AreaRegistration.RegisterAllAreas(); WebApiConfig.Register(GlobalConfiguration.Configuration); FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters); RouteConfig.RegisterRoutes(RouteTable.Routes);//在此方法中添加路由规则
 BundleConfig.RegisterBundles(BundleTable.Bundles); AuthConfig.RegisterAuth(); } } }

View Code

 

 
  RouteConfig.RegisterRoutes(RouteTable.Routes);//在此方法中添加路由规则

 

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using System.Web.Routing; namespace MVC4多语言IHttpModule实现 { public class RouteConfig { public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Globalization", // 路由名称
               "{lang}/{controller}/{action}/{id}", // 带有参数的 URL
               new { lang = "zh", controller = "Home", action = "Index", id = UrlParameter.Optional }, // 参数默认值
               new { lang = "^[a-zA-Z]{2}(-[a-zA-Z]{2})?$" }    //参数约束
 ); routes.MapRoute( name: "Default", url: "{controller}/{action}/{id}", defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional } ); } } }

而后在配置文件中声明:
在web.config下的system.web下

<configuration>
    <system.web>
        <httpModules> 
            <add name="MyModule" type="MyModule"/> 
        </httpModules> 
    </system.web>
</configuration>
事践显示这种声明注册方法在IIS7.0下，即win7下是不work的。
必须按以下声明：
<configuration> 
    <system.webServer> 
        <modules> 
            <add name="MyModule" type="MyModule"/> 
        </modules>   
    </system.webServer>
</configuration>
