MVC4多语言IHttpModule实现

最近项目需要多语言环境了.

由于项目页面较多,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.

首先创建以个mvc4的应用程序,
添加资源文件夹(自定义)Lang ,
然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的视图中添加如下代码:
@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,其他无类

然后添加以个实现了IHttpModule的类,暂且命名为MyModule
此类需要实现2个方法
 public void Dispose() { } 即可
 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;
 }
 }
}

 

 

 然后添加路由 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();
 }
 }
}

 

 
  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 }
 );
 }
 }
}

 

 

然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。
必须按如下声明：
<configuration> 
    <system.webServer> 
        <modules> 
            <add name="MyModule" type="MyModule"/> 
        </modules>   
    </system.webServer>
</configuration>
