ASP .NET Core 默认语言始终为英语 [英] ASP .NET Core default language is always English

问题描述

我按照 Microsoft 的博客中的描述设置了本地化，但默认语言始终为英语.这就是我的 Startup.cs 在本地化方面的样子.

I set the localization as described in Microsoft's blog, but the default language is always English. This is how my Startup.cs looks like with regards to the localization.

CultureInfo[] supportedCultures = new[]
            {
                new CultureInfo("ar"),
                new CultureInfo("en") 
            };

在 ConfigureServices 方法中:

In ConfigureServices method:

    services.Configure<RequestLocalizationOptions>(options =>
        {
            options.DefaultRequestCulture = new RequestCulture("ar", "ar");
            options.SupportedCultures = supportedCultures;
            options.SupportedUICultures = supportedCultures;
        });
        services.AddLocalization(options =>
        {
            options.ResourcesPath = "Resources";
        });


        services.AddMvc()
        .AddViewLocalization()
        .AddDataAnnotationsLocalization();

在配置方法中:

        app.UseRequestLocalization(new RequestLocalizationOptions()
        {
            DefaultRequestCulture = new RequestCulture("ar"),
            SupportedCultures = supportedCultures,
            SupportedUICultures = supportedCultures
        });

谢谢:)

推荐答案

您正在将 "arabic" 设置为 DefaultRequestCulture 但如果没有内置的，则使用 DefaultRequestCulture提供者可以确定请求文化.默认提供程序是:

You are setting "arabic" as DefaultRequestCulture but DefaultRequestCulture is used if none of the built-in providers can determine the request culture. The default providers are:

1. QueryStringRequestCultureProvider
2. CookieRequestCultureProvider
3. AcceptLanguageHeaderRequestCultureProvider

文化很可能是由浏览器发送的 Accept-Language HTTP 标头确定的.

Most likely the culture is determined from the Accept-Language HTTP header that the browser is sending.

您必须删除 AcceptLanguageHeaderRequestCultureProvider 以回退到 DefaultRequestCulture.为此，我们可以覆盖 RequestLocalizationOptions 的 RequestCultureProviders 列表并仅使用其他两个提供程序.在 Startup.cs 中:

You have to remove the AcceptLanguageHeaderRequestCultureProvider in order to fallback to DefaultRequestCulture. To do that, we can overwrite the RequestCultureProviders list of RequestLocalizationOptions and use only the other two providers. In Startup.cs:

public void ConfigureServices(IServiceCollection services)
{
    CultureInfo[] supportedCultures = new[]
    {
        new CultureInfo("ar"),
        new CultureInfo("en")
    };

    services.Configure<RequestLocalizationOptions>(options =>
    {
        options.DefaultRequestCulture = new RequestCulture("ar");
        options.SupportedCultures = supportedCultures;
        options.SupportedUICultures = supportedCultures;
        options.RequestCultureProviders = new List<IRequestCultureProvider>
        {
            new QueryStringRequestCultureProvider(),
            new CookieRequestCultureProvider()
        };
    });
}

并且在 Configure 方法中只需在 app.UseMvc();

and in Configure method just use app.UseRequestLocalization(); before app.UseMvc();
