Nopcommerce 重写控制器

Question

我正在尝试覆盖 Nopcommerce 产品控制器中的方法，但失败了。

在我的插件中，我成功地扩展了服务 classes，但是当涉及到覆盖控制器时，我遇到了问题并且它没有到达断点。

所以我试图重写 Nop.Web.Controllers.Product

中的虚方法 PrepareProductDetailsPageModel

    [NonAction]
    protected virtual ProductDetailsModel PrepareProductDetailsPageModel(Product product, 
        ShoppingCartItem updatecartitem = null, bool isAssociatedProduct = false)
    {
    }

我正在创建我的新 class ProductController.cs 如：

  public partial class ProductController :      Nop.Web.Controllers.ProductController
     { 

     #region Fields

    private readonly ICategoryService _categoryService;
    private readonly IManufacturerService _manufacturerService;
    private readonly IProductService _productService;

    private readonly IProductAttributeService _productAttributeService;

    private readonly IDateTimeHelper _dateTimeHelper;
    private readonly IRecentlyViewedProductsService _recentlyViewedProductsService;
    private readonly ICompareProductsService _compareProductsService;
    private readonly IWorkflowMessageService _workflowMessageService;
    private readonly IProductTagService _productTagService;
    private readonly IOrderReportService _orderReportService;
    private readonly IBackInStockSubscriptionService _backInStockSubscriptionService;
    private readonly IAclService _aclService;
    private readonly IStoreMappingService _storeMappingService;
    private readonly IPermissionService _permissionService;
    private readonly ICustomerActivityService _customerActivityService;
    private readonly IProductAttributeParser _productAttributeParser;
    private readonly IShippingService _shippingService;

     }

但是，这不会命中我重写的方法。

谁能帮忙，请告诉我我做错了什么。

覆盖 TaxService.cs 时，我在 DependencyRegistrar 中注册了我的 TaxService。

我应该为这个控制器做些什么吗？

感谢您的帮助。

对于遇到此问题的任何其他人，我现在已经解决了。

您需要在 DependencyRegistrar 中注册您的控制器，基本上添加这一行...

   public virtual void Register(ContainerBuilder builder, ITypeFinder typeFinder)
   {
      builder.RegisterType<YourPlugin.Controllers.
      ProductController>().As<Nop.Web.Controllers.ProductController>();
   }
   public int Order
   {
        get { return 100; }
   }

然后这将命中您重写的方法。

另外记得把Order设为100，不知道下限是多少。

使用 autofac 注册组件是一个很好的解决方案。您还可以在 Route.cs 中进行更改，以便将具有 url : /plugin/controller/XXX 的新控制器指向前一个
