Перезаписать Generi c Route в nopcommerce бета-версии 4.3

Question

Я пишу плагин для nopcommerce beta 4.3 и пытаюсь переписать общий c маршрут (Category / Slug). Приложение было перемещено в. net core 3.x, и поэтому маршрутизация теперь находится в промежуточном программном обеспечении и обрабатывается иначе, чем раньше. Я попытался перезаписать Nop.Web.Infrastructure.GenericUrlRouteProvider и Nop.Web.Framework. Mvc .Routing.SlugRouteTransformer, как показано ниже ...

public partial class GenericUrlRouteProviderExt : IRouteProvider
{
    #region Methods

    /// <summary>
    /// Register routes
    /// </summary>
    /// <param name="endpointRouteBuilder">Route builder</param>
    public void RegisterRoutes(IEndpointRouteBuilder endpointRouteBuilder)
    {
        var pattern = "{SeName}";
        if (DataSettingsManager.DatabaseIsInstalled)
        {
            var localizationSettings = endpointRouteBuilder.ServiceProvider.GetRequiredService<LocalizationSettings>();
            if (localizationSettings.SeoFriendlyUrlsForLanguagesEnabled)
            {
                var langservice = endpointRouteBuilder.ServiceProvider.GetRequiredService<ILanguageService>();
                var languages = langservice.GetAllLanguages().ToList();
                pattern = "{language:lang=" + languages.FirstOrDefault().UniqueSeoCode + "}/{SeName}";
            }
        }
        endpointRouteBuilder.MapDynamicControllerRoute<SlugRouteTransformerExt>(pattern);

        endpointRouteBuilder.MapControllerRoute("WineCategory", pattern,
             new { controller = "Wine", action = "WineCategory" });
   }

    #endregion

    #region Properties

    /// <summary>
    /// Gets a priority of route provider
    /// </summary>
    /// <remarks>
    /// it should be the last route. we do not set it to -int.MaxValue so it could be overridden (if required)
    /// </remarks>
    public int Priority => 1000;

    public int Order => 1;

                break;
        }

        return new ValueTask<RouteValueDictionary>(values);
    }
}

но получите сообщение об ошибке: Использование ExpandEndpoint требует, чтобы замененная конечная точка имела уникальный приоритет. Следующие конечные точки были найдены с одинаковым приоритетом ...

Я ищу эффективный способ перехватить указанный маршрут и перенаправить его ...

Я также пытался это сделать в PluginStratup не знаю, к кому подойти ...

public void Configure(IApplicationBuilder application)
    {

        //our custom middleware
        application.Use(async (context, next) =>
        {


            await next();

        });
    }

Кто-нибудь изучал это и нашел решение?

Я не прочитал весь код, который вы выложили, но если я правильно понимаю, вы просто пытаетесь угнать маршрут.

Взгляните на Nop.Web.Infrastructure.GenericUrlRouteProvider.RegisterRoutes(), вот где категория / маршрут пули определен.

Все, что вам нужно сделать в вашем плагине, это определить класс, реализующий IRouteProvider с Приоритетом, превышающим -1000000 (который является Приоритетом, используемым GenericUrlRouteProvider)

Например:

using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Routing;
using Microsoft.Extensions.DependencyInjection;
using Nop.Core.Domain.Localization;
using Nop.Data;
using Nop.Services.Localization;
using Nop.Web.Framework.Mvc.Routing;
using System.Linq;

namespace Namespace
{
    public class RouteProvider : IRouteProvider
    {
        /// <summary>
        /// Register routes
        /// </summary>
        /// <param name="endpointRouteBuilder">Route builder</param>
        public void RegisterRoutes(IEndpointRouteBuilder endpointRouteBuilder)
        {
            var pattern = "{SeName}";
            if (DataSettingsManager.DatabaseIsInstalled)
            {
                var localizationSettings = endpointRouteBuilder.ServiceProvider.GetRequiredService<LocalizationSettings>();
                if (localizationSettings.SeoFriendlyUrlsForLanguagesEnabled)
                {
                    var langservice = endpointRouteBuilder.ServiceProvider.GetRequiredService<ILanguageService>();
                    var languages = langservice.GetAllLanguages().ToList();
                    pattern = "{language:lang=" + languages.FirstOrDefault().UniqueSeoCode + "}/{SeName}";
                }
            }

            endpointRouteBuilder.MapControllerRoute("overriden_Category", pattern, new { controller = "OverridenCatalog", action = "Category" });
        }

        /// <summary>
        /// Gets a priority of route provider
        /// </summary>
        public int Priority => 0;
    }
}

Измените это, чтобы указать ваш правильный контроллер / действие
