.NET Core WebApi 多语言本地化,动态切换多语言

.NET Core WebApi 多语言本地化,动态切换多语言

1. 原生的.net core webapi 动态多语言本地话

   • 具体更多详细内容,可以参考官方文档

   • 首先看效果图

     • 

   • 整体项目结构图

     • 

   • 开始前需要讲一些重要的点

     • 1.是通过文件命名空间的路径去找寻的,比如 Resource.cs 是在和多语言Resource.xxxx.resx文件同一级别的 2.参考下图,不然多语言翻译时是找寻不到的 

     •

2. ConfigureServices里面进行以下配置

   services.AddLocalization();             services.Configure<RequestLocalizationOptions>(options =>             {                 var supportedCultures = new List<CultureInfo>                 {                     new CultureInfo("en-US"),//英文                     new CultureInfo("zh-Hans"),//简体中文                     new CultureInfo("zh-Hant")//繁体中文-台湾                 };                                  options.DefaultRequestCulture = new RequestCulture(culture: "en-US", uiCulture: "en-US");                 options.SupportedCultures = supportedCultures;                 options.SupportedUICultures = supportedCultures;                 options.RequestCultureProviders = new List<IRequestCultureProvider> { new CultureRequestCultureProvider() };             }); 

3. Configure下加入如下代码

   //多语言配置             var localizeOptions = app.ApplicationServices.GetService<IOptions<RequestLocalizationOptions>>();             app.UseRequestLocalization(localizeOptions.Value); 

4. 其中关键的 CultureRequestCultureProvider.cs 代码内容如下 (通过HttpContext 的Headers 传参 Accept-Language来实现动态切换语言的)

    public class CultureRequestCultureProvider : RequestCultureProvider     {         public override Task<ProviderCultureResult> DetermineProviderCultureResult(HttpContext httpContext)         {             if (httpContext == null)             {                 throw new ArgumentNullException();             }              #region 方式一从Cookies里面按需获取语言 注释             //var CULTURE_String = "CULTURE";             //var CultureValue = httpContext.Request.Cookies[CULTURE_String]?.ToString() ?? "";             //if (string.IsNullOrWhiteSpace(CultureValue))             //{             //    CultureValue = "zh-Hans";             //    httpContext.Response.Cookies.Append(key: CULTURE_String, value: CultureValue, options: new CookieOptions() { Expires = DateTime.Now.AddYears(1) });             //}              #endregion              //方式二 从Headers里面按需获取语言             var culture = new StringSegment("zh-Hans");             var uiCulture = new StringSegment("zh-Hans");             var lang = httpContext.Request.Headers["Accept-Language"].ToString() ?? "";             switch (lang)             {                 case "en-US":                     //英文                     culture = new StringSegment("en-US");                     uiCulture = new StringSegment("en-US");                     break;                 case "zh-Hans":                     //简体中文                     culture = new StringSegment("zh-Hans");                     uiCulture = new StringSegment("zh-Hans");                     break;                 case "zh-Hant":                     //繁体中文-台湾                     culture = new StringSegment("zh-Hant");                     uiCulture = new StringSegment("zh-Hant");                     break;                 default:                     goto case "zh-Hans";             }             return Task.FromResult(new ProviderCultureResult(culture, uiCulture));         }     } 

5. Resource.cs 以及多语言文件的代码如下

   namespace DynamicMultilanguage.Localize {     public class Resource     {     } } 

   

   

   

6. 在控制器里面使用时

   		private readonly IStringLocalizer<Resource> _localizer;          public HomeController(IStringLocalizer<Resource> localizer)         {             _localizer = localizer;         }   		[HttpGet]         public object Get()         {             var culturesValue = _localizer["Home"];             var culturesValueParams = _localizer["HomeTitie", "雨太阳", "66666"];              return new { culturesValue, culturesValueParams };         } 

   按照以上操作,一个简答的WebApi的多语言切换已经完成了
