c# - 在 ASP.NET Core 中嵌入 View 本地化

Question

我有一个 ASP.NET 网站。我成功地从另一个项目加载了嵌入 View ，但我无法运行本地化。它适用于启动程序集的 View ，但在加载嵌入 View 时出现错误消息:

InvalidOperationException: No service for type 'Microsoft.AspNetCore.Mvc.Localization.IHtmlLocalizer' has been registered.

View 代码如下:

_ViewImports.cshtml(嵌入):

@using Microsoft.AspNetCore.Mvc.Localization
@inject IHtmlLocalizer Localizer
@addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers

Index.cshtml(嵌入)

@{
    ViewData["Title"] = Localizer["Home"];
}

<div>
    @Localizer["Test"]
</div>

我的 startup.cs(在主项目中)如下所示:

namespace My.Name.Space //Not the real one
{
    public class Startup
    {
        public Startup(IHostingEnvironment env)
        {
            //Standard builder function
        }

        public IConfigurationRoot Configuration { get; set; }

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

            //Add EF DbContext, identity, etc.

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

            //Localization

            var supportedCultures = GetListOfCultures();

            services.Configure<RequestLocalizationOptions>(options =>
            {
                options.DefaultRequestCulture = new RequestCulture(culture: "en-US", uiCulture: "en-US");
                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);

            loggerFactory.AddConsole(Configuration.GetSection("Logging"));
            loggerFactory.AddDebug();

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

                // For more details on creating database during deployment see http://go.microsoft.com/fwlink/?LinkID=615859
                try
                {
                    using (var serviceScope = app.ApplicationServices.GetRequiredService<IServiceScopeFactory>()
                        .CreateScope())
                    {
                        serviceScope.ServiceProvider.GetService<ApplicationDbContext>()
                             .Database.Migrate();
                    }
                }
                catch { }
            }

            app.UseStaticFiles();

            app.UseIdentity();

            // To configure external authentication please see http://go.microsoft.com/fwlink/?LinkID=532715

            app.UseMvc(routes =>
            {
                // Areas support
                routes.MapRoute(
                    name: "areaRoute",
                    template: "{area:exists}/{controller=Home}/{action=Index}/{id?}");

                routes.MapRoute(
                    name: "default",
                    template: "{controller=Home}/{action=Index}/{id?}");
            });
        }
    }
}

我是不是遗漏了什么或者是 RC2 中的错误？

问候，

Answer 1

我的应用程序从 RC1 升级到 RC2 时遇到了完全相同的问题。

我变了

services.AddLocalization(options => options.ResourcesPath = "Resources");

到

services.AddLocalization();

您的 Web 项目的 Resources 文件夹中需要有 *.resx 文件才能工作。
