MVC3过滤器实现多语言

如题，以中英文为例。

一、添加Resources文件

1. 创建Global.resx

2.创建Global.en-US.resx

3.向Global.resx和Global.en-US.resx中填入对应的键值

注意：Global.resx 的AccessModifer 要改成Public

 二、添加过滤器

1.创建InternationalizationAttribute类

View Code 
 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Web;
 5 using System.Web.Mvc;
 6 using System.Threading;
 7 using System.Globalization;
 8 using System.Web.Routing;
 9 
10 namespace MMSReport.Web.Common
11 {
12     public class InternationalizationAttribute : ActionFilterAttribute 
13     {
14         public override void OnActionExecuting(ActionExecutingContext filterContext)
15         {
16             if (filterContext.RouteData.Values["lang"] != null && !string.IsNullOrWhiteSpace(filterContext.RouteData.Values["lang"].ToString()))
17             {
18                 ///从路由数据(url)里设置语言  
19                 var lang = filterContext.RouteData.Values["lang"].ToString();
20                 Thread.CurrentThread.CurrentUICulture = CultureInfo.CreateSpecificCulture(lang);
21             }
22             else
23             {
24                 ///从cookie里读取语言设置  
25                 var cookie = filterContext.HttpContext.Request.Cookies["MvcLocalization.CurrentUICulture"];
26                 var langHeader = string.Empty;
27                 if (cookie != null)
28                 {
29                     ///根据cookie设置语言  
30                     langHeader = cookie.Value;
31                     Thread.CurrentThread.CurrentUICulture = CultureInfo.CreateSpecificCulture(langHeader);
32                 }
33                 else
34                 {
35                     ///如果读取cookie失败则设置默认语言  
36                     langHeader = filterContext.HttpContext.Request.UserLanguages[0];
37                     Thread.CurrentThread.CurrentUICulture = CultureInfo.CreateSpecificCulture(langHeader);
38                 }
39 
40                 ///把语言值设置到路由值里  
41                 filterContext.RouteData.Values["lang"] = langHeader;
42             }
43 
44             /// 把设置保存进cookie  
45             HttpCookie _cookie = new HttpCookie("MvcLocalization.CurrentUICulture", Thread.CurrentThread.CurrentUICulture.Name);
46             _cookie.Expires = DateTime.Now.AddYears(1);
47             filterContext.HttpContext.Response.SetCookie(_cookie);
48         }
49     }
50 }

其中使用Cookie记录默认语言

2.文件结构如图

三、设置路由Global.asax

View Code 
 1  public class MvcApplication : SpringMvcApplication // System.Web.HttpApplication
 2     {
 3         public static void RegisterGlobalFilters(GlobalFilterCollection filters)
 4         {
 5             filters.Add(new HandleErrorAttribute());
 6             filters.Add(new InternationalizationAttribute());
 7         }
 8 
 9         public static void RegisterRoutes(RouteCollection routes)
10         {
11             routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
12 
13             routes.MapRoute(
14                "Globalization", // 路由名称
15                "{lang}/{controller}/{action}/{id}", // 带有参数的 URL
16                new {  controller = "Home", action = "Index", id = UrlParameter.Optional }, // 参数默认值
17                new { lang = "^[a-zA-Z]{2}(-[a-zA-Z]{2})?$" }    //参数约束
18            );
19 
20             routes.MapRoute(
21                 "Default", // Route name
22                 "{controller}/{action}/{id}", // URL with parameters
23                 new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
24             );
25 
26         }
27 
28         protected void Application_Start()
29         {
30             log4net.Config.XmlConfigurator.Configure();
31 
32             AreaRegistration.RegisterAllAreas();
33 
34             RegisterGlobalFilters(GlobalFilters.Filters);
35             RegisterRoutes(RouteTable.Routes);
36         }
37 
38     }

关键代码：

1. filters.Add(newInternationalizationAttribute());

2.

routes.MapRoute(

"Globalization", // 路由名称  

"{lang}/{controller}/{action}/{id}", // 带有参数的 URL

new { 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  

);

 四、页面显示

1.HomeController

View Code 
 1  public class HomeController : Controller
 2     {          
 3         public ActionResult Index()
 4         {
 5              return View();
 6         }
 7 
 8         public ActionResult Index2()
 9         { 
10             return View();
11         }
12 
13         public ActionResult ChangeLanguage(string lang)
14         {
15             return new RedirectResult("Index");
16         }         
17     }

2.Index.cshtml中使用多语言标签替换原来的文字

View Code 
 1 <h2>Index</h2>
 2     <div>
 3         <div>
 4             <div>
 5                 [ @Html.ActionLink("English", "ChangeLanguage", "Home", new { lang = "en-US" }, null)
 6                 ] [ @Html.ActionLink("中文", "ChangeLanguage", "Home", new { lang = "zh-CN" }, null)
 7                 ]
 8             </div>
 9             <div> 
10             <span>@MMSReport.Resource.Global.UserName</span>
11             <span>@MMSReport.Resource.Global.UserPwd</span>
12             </div>
13         </div>
14       @Html.ActionLink("Index2","Index2")
15     </div>

3.Index2.cshtml用来做一个简单的跳转测试

View Code 
1 <h2>Index2</h2>
2 
3 <h1>@MMSReport.Resource.Global.Index2</h1>
4 
5       @Html.ActionLink("Index","Index")

五、运行

结束
