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博客中的说明设置了本地化，但是默认语言始终是英语.这是我的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

您将阿拉伯语"设置为DefaultRequestCulture，但是如果没有任何内置提供程序可以确定请求区域性，则使用DefaultRequestCulture.默认提供程序为:

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

1. QueryStringRequestCultureProvider
2. CookieRequestCultureProvider
3. AcceptLanguageHeaderRequestCultureProvider

很有可能是根据浏览器正在发送的Accept-Language HTTP标头确定区域性的.

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

您必须删除AcceptLanguageHeaderRequestCultureProvider才能回退到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:

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()
        };
    });
}

和Configure方法中，只需在app.UseMvc();
