ASP.NET Core 3.0 Razor Pages 中的路由本地化

Question

我想在我的 ASP.NET Core 3.0 Razor Pages 应用程序中使用路由本地化。

/sf/answers/3708363781/似乎有 2.2 的解决方案，但现在有没有更好的方法在 3.0 中做到这一点，因为它已经重新设计了路由/端点？

Answer 1

ASP.NET Core 3.0 引入了端点路由的新功能，通过它我们可以在进入 MVC 之前从路由数据中获取文化。这使我们可以根据当前路线对内容进行本地化，而无需太多努力。

如何

首先，确保本地化服务已注册并且您已配置支持的文化，如下所示：

services.AddLocalization(opts =>  opts.ResourcesPath = "Resources" );
services.Configure<RequestLocalizationOptions>(options =>
{
    var supportedCultures = new[]{
        new CultureInfo("en-US"),
        new CultureInfo("de"),
        new CultureInfo("it"),
        // ... others
    };
    options.SupportedCultures = supportedCultures;
    options.SupportedUICultures = supportedCultures;
    options.RequestCultureProviders.Insert(0, new RouteDataRequestCultureProvider());
});

然后添加一个UseRequestLocalization中间件并为文化配置一条路由，以便它可以正确获取文化信息：

app.UseRouting();
app.UseRequestLocalization();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
    endpoints.MapControllerRoute(name: "culture-route", pattern:"{culture=en-US}/{controller=Home}/{action=Index}/{id?}"); 
    endpoints.MapControllerRoute( name: "default", pattern: "{controller=Home}/{action=Index}/{id?}");
});

注意上面的命令很重要。

抱歉，我没注意到你要 Razor 页面。要使用 Razor Page WebApp，请创建一个自定义IPageRouteModelConvention来映射路由：

public class CustomCultureRouteRouteModelConvention : IPageRouteModelConvention
{
    public void Apply(PageRouteModel model)
    {
        List<SelectorModel> selectorModels = new List<SelectorModel>();
        foreach (var selector in model.Selectors.ToList())
        {
            var template = selector.AttributeRouteModel.Template;
            selectorModels.Add(new SelectorModel(){
                AttributeRouteModel = new AttributeRouteModel
                {
                    Template = "/{culture}" + "/" + template
                }
            });
        }
        foreach(var m in selectorModels){
            model.Selectors.Add(m);
        }
    }
}

并添加此页面约定：

services.AddRazorPages().AddRazorPagesOptions(opts =>
{
    opts.Conventions.Add(new CustomCultureRouteRouteModelConvention());
});
services.AddLocalization(opts => opts.ResourcesPath = "Resources");
services.Configure<RequestLocalizationOptions>(options =>
{
    var supportedCultures = new[]{
        new CultureInfo("en-US"),
        new CultureInfo("de"),
        new CultureInfo("it"),
        new CultureInfo("zh"),
    };
    options.SupportedCultures = supportedCultures;
    options.SupportedUICultures = supportedCultures;
    options.RequestCultureProviders.Insert(0, new RouteDataRequestCultureProvider());
});

中间件：

app.UseRouting();

app.UseRequestLocalization();

app.UseAuthorization();

app.UseEndpoints(endpoints =>
{
    endpoints.MapRazorPages();
    //endpoints.MapControllerRoute(name: "culture-route", pattern:"{culture=en-US}/{controller=Home}/{action=Index}/{id?}");
    //endpoints.MapControllerRoute( name: "default", pattern: "{controller=Home}/{action=Index}/{id?}");
});
