Asp.Net Core中的本地化 [英] Localization in Asp.Net Core

问题描述

我一直按照本页上的说明设置本地化:

I have been following the instructions on this page to setup Localization:

https://docs.microsoft.com/zh-CN /aspnet/core/fundamentals/localization

但是，对我而言，它似乎不起作用.这是我所做的:

However, for me it just doesn't seem to work. Here is what I have done:

Startup.cs:

Startup.cs:

public class Startup
{
    public IConfigurationRoot Configuration { get; }

    public Startup(IHostingEnvironment env)
    {
        var builder = new ConfigurationBuilder()
            .SetBasePath(env.ContentRootPath)
            .AddJsonFile("appsettings.json", true, true);

        builder.AddEnvironmentVariables();
        Configuration = builder.Build();
    }

    public void ConfigureServices(IServiceCollection services)
    {
        services.AddLocalization(o => o.ResourcesPath = "Resources");
        services.AddMvc(o =>
        {
            o.Filters.Add(typeof(GlobalExceptionFilter));
        }
        ).AddViewLocalization(LanguageViewLocationExpanderFormat.Suffix).AddDataAnnotationsLocalization();
    }

    public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
    {
        var supportedCultures = new[]
        {
            new CultureInfo("es-MX"),
            new CultureInfo("en-US")
        };

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

        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }
        else
        {
            app.UseExceptionHandler("/Error");
        }

        app.UseStaticFiles();
        app.UseAuthentication();

        app.UseMvcWithDefaultRoute();
        //app.UseMvc(routes =>
        //{
        //    routes.MapRoute(
        //        "default", "{controller=Home}/{action=Index}/{id?}");
        //});

        app.UseRewriter(new RewriteOptions().AddRedirectToHttps());
    }
}

我的Layout.cshtml包含以下内容:

My Layout.cshtml contains the following:

@await Html.PartialAsync("_SelectLanguagePartial")

和我的_SelectLanguagePartial.cshtml包含:

and my _SelectLanguagePartial.cshtml contains:

@using Microsoft.AspNetCore.Builder
@using Microsoft.AspNetCore.Localization
@using Microsoft.AspNetCore.Mvc.Localization
@using Microsoft.Extensions.Options

@inject IViewLocalizer Localizer
@inject IOptions<RequestLocalizationOptions> LocOptions

@{
    var requestCulture = Context.Features.Get<IRequestCultureFeature>();
    var cultureItems = LocOptions.Value.SupportedUICultures
        .Select(c => new SelectListItem { Value = c.Name, Text = c.DisplayName })
        .ToList();
    var returnUrl = string.IsNullOrEmpty(Context.Request.Path) ? "~/" : $"~{Context.Request.Path.Value}";
}

<div title="@Localizer["Request culture provider:"] @requestCulture?.Provider?.GetType().Name">
    <form id="selectLanguage" asp-controller="Home" asp-action="SetLanguage" asp-route-returnUrl="@returnUrl" 
          method="post" role="form">
        <label asp-for="@requestCulture.RequestCulture.UICulture.Name">@Localizer["Language:"]</label> <select name="culture"
            onchange="this.form.submit();"
            asp-for="@requestCulture.RequestCulture.UICulture.Name" asp-items="cultureItems">
        </select>
    </form>
</div>

除此之外，我还创建了两个资源文件ErrorMessages.ex-MX.resx和ErrorMessages.resx.

In addition to this, I have created 2 resource files, ErrorMessages.ex-MX.resx and ErrorMessages.resx.

在我的HomeController中，我添加了这行ViewBag.Test = ErrorMessages.Test;，在索引视图中，我添加了<p>@ViewBag.Test</p>

In my HomeController I have added this line ViewBag.Test = ErrorMessages.Test; and in the Index view I added <p>@ViewBag.Test</p>

当我查看页面时，会看到带有语言的下拉列表，并且只列出了英语.我在页面上显示的文本是来自ErrorMessages.resx的文本.

When I look at the page I see the drop down with languages and it only has English listed there. The text that I displayed on the page is the one coming from ErrorMessages.resx.

我错过了一步吗?为什么西班牙语在任何地方都没有被拾起?正如您将在下面看到的那样，我什至尝试将西班牙语设置为主要文化，但没有区别.

Am I missing a step? How come Spanish is not getting picked up anywhere? As you will see below, I even tried setting spanish as the main culture, yet no difference.

我尝试从列表中删除eglish，结果下拉菜单仍然存在，这次列出了西班牙语.但是，该文本仍为英文.

I tried removing eglish from the list and the result that I got the dropdown was still there and this time it had Spanish listed. However, the text was still in English.

然后，我尝试将英语作为第二项添加回该列表中，并将英语设置为主语言，并且下拉菜单仅显示一种语言，而西班牙语消失了.

Then I tried adding English back as a second list in the item and setting english as the main language and the dropdown only displayed 1 language and spanish was now gone.

推荐答案

大约一周前，我遇到了同样的问题.我用这个解决了:

I had this same problem around a week ago. I solved it with this:

public void ConfigureServices(IServiceCollection services)
{
    services.AddLocalization(options => options.ResourcesPath = "Resources");

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

    services.Configure<RequestLocalizationOptions>(options =>
    {
        var supportedCultures = new[] { new CultureInfo("en"), new CultureInfo("es") };

        options.DefaultRequestCulture = new RequestCulture(culture: "en", uiCulture: "en");
        options.SupportedCultures = supportedCultures;
        options.SupportedUICultures = supportedCultures;
    });
}

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    var locOptions = app.ApplicationServices.GetService<IOptions<RequestLocalizationOptions>>();
    app.UseRequestLocalization(locOptions.Value);

    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
        app.UseBrowserLink();
    }
    else
    {
        app.UseExceptionHandler("/Home/Error");
    }

    app.UseStaticFiles();
    app.UseMvcWithDefaultRoute();
}

不过，还有一条评论.在ASP.NET Core中，不应创建默认的区域性资源，而只能创建特定的区域性资源:

One more comment, though. In ASP.NET Core, the default culture resource should not be created, only specific ones:

所以，给定

Views/Shared/Layout.cshtml

仅创建

Resources/Views/Shared/Layout.es-MX.resx

还要注意，您以此限制西班牙语为墨西哥语，因此您应该使用es后备广告，或同时添加es和es-MX.

Do notice, also, that you are limiting Spanish to Mexican by this, so you should either have a es fallback, or add both es and es-MX.
