Asp.net core Localization 总是返回英语文化 [英] Asp.net core Localization always returns english clulture

问题描述

我正在尝试开发一个多语言项目.对于静态值，我使用了资源(.resx 文件)

I am trying to develop a multilanguage project.For static value I used resource(.resx file )

我创建了两个资源文件Home.resx(默认或英语)和 home.resx(用于阿拉伯语)它适用于默认或英语

I create two resources file Home.resx(default or English) and home.resx(for the Arabic language) it works for default or English

然后我尝试更改语言

System.Threading.Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("ar");
 var home = Resources.Home.Home1;

但它仍然返回英文值而不是阿拉伯值

But it still return English value instead of Arabic value

这是我的 startup.cs 配置函数

here is my startup.cs Configure function

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {

   var supportedCultures = new List<System.Globalization.CultureInfo>
            {
                new System.Globalization.CultureInfo("en-US"),

                new System.Globalization.CultureInfo("ar-AR"),

            };
            var options = new RequestLocalizationOptions
            {
                DefaultRequestCulture = new Microsoft.AspNetCore.Localization.RequestCulture("en-US"),
                SupportedCultures = supportedCultures,
                SupportedUICultures = supportedCultures
            };
            app.UseRequestLocalization(options);
......

我的代码有什么问题?

推荐答案

好的，我会告诉你我在项目中做了什么.在 Startup.cs 的 ConfigureServices 方法中的 services.AddMvc() 之后键入以下代码.

Ok, I will tell you what I do in my projects. Type the following code after services.AddMvc() in your ConfigureServices method of the Startup.cs.

IList<CultureInfo> supportedCultures = new List<CultureInfo>
{
    new CultureInfo("en-US"),
    new CultureInfo("fr-FR"),
    new CultureInfo("el-GR"),
};

var MyOptions = new RequestLocalizationOptions()
{
    DefaultRequestCulture = new RequestCulture(culture: "en-US", uiCulture: "en-US"),
    SupportedCultures = supportedCultures,
    SupportedUICultures = supportedCultures
};
MyOptions.RequestCultureProviders = new[]
{
     new RouteDataRequestCultureProvider() { RouteDataStringKey = "lang", Options = MyOptions }
};

services.AddSingleton(MyOptions);

现在在您的项目中定义以下类

Now define the following class in your project

public class LocalizationPipeline
{
    public void Configure(IApplicationBuilder app, RequestLocalizationOptions options)
    {
        app.UseRequestLocalization(options);
    }
}

更改您的默认路由:

app.UseMvc(routes =>
{
    routes.MapRoute(
        name: "default",
        template: "{lang=en-US}/{controller=Home}/{action=Index}/{id?}");
});

为每个控制器使用 MiddlewareFilter.

In use the MiddlewareFilter for each of your controllers.

[MiddlewareFilter(typeof(LocalizationPipeline))]
public class HomeController : Controller
{
    public string GetCulture()
    {
        return $"CurrentCulture:{CultureInfo.CurrentCulture.Name}, CurrentUICulture:{CultureInfo.CurrentUICulture.Name}";
    }
}

您可以像这样更改当前语言:

You can change the current language like this:

<ul>
    <li>@Html.ActionLink("EN", ViewContext.RouteData.Values["action"] as string, ViewContext.RouteData.Values["controller"] as string, new { lang = "en-US" })</li>
    <li>@Html.ActionLink("FR", ViewContext.RouteData.Values["action"] as string, ViewContext.RouteData.Values["controller"] as string, new { lang = "fr-FR" })</li>
    <li>@Html.ActionLink("GR", ViewContext.RouteData.Values["action"] as string, ViewContext.RouteData.Values["controller"] as string, new { lang = "el-GR" })</li>
</ul>

如果您还想支持 Razor Pages，请进行以下更改.添加以下更改 servcies.AddMvc().

If you want to support Razor Pages as well, make the following changes. Add the following change the servcies.AddMvc().

services.AddMvc()
    .AddRazorPagesOptions(options =>
    {
        options.Conventions.AddFolderRouteModelConvention("/", model =>
        {
            foreach (var selector in model.Selectors)
            {
                var attributeRouteModel = selector.AttributeRouteModel;
                attributeRouteModel.Template = AttributeRouteModel.CombineTemplates("{lang=el-GR}", attributeRouteModel.Template);
            }
        });
    });

在您的 PageModels 上使用以下 MiddlewareFilter 属性

Use the following MiddlewareFilter attribute over your PageModels

[MiddlewareFilter(typeof(LocalizationPipeline))]
public class ContactModel : PageModel
{
    public string Message { get; set; }

    public void OnGet()
    {
        Message = "Your contact page.";
    }
}

我唯一没有做的事情是通过在 Startup.cs 中以编程方式添加 MiddlewareFilter 来为所有控制器和 PageModels 自动定义 LocalizationPipeline.

The only thing that I have not managed to do is to automatically define the LocalizationPipeline for all the controllers and PageModels by adding the MiddlewareFilter programmatically inside the Startup.cs.
