Question

努力实现：
我正在写一个宁静的插件，允许从外部相关系统（网站）搜索产品。并允许他们在自己的网站上展示我们的产品。

我不想从头开始编写所有内容，而是想使用已经在NopCommerce中编写的内容。我已经设法搜索产品，但是我无法通过使用已存在的东西获得产品图像。

在CatalogController内，我看到SearchTermAutoComplete ActionResult，它正是我想要的。但我无法从我的插件代码中调用它。我不想将控制器文件/代码复制到插件项目中。因为，那么我将不得不复制所有扩展对象和其他依赖项。

在MVC / NopCommerce中有没有办法访问控制器代码并从插件中调用它们？

插件代码：

public ActionResult Search(String authToken, string keywords)
        {
            if (!IsAuthTokenValid(authToken, out _tokenStatus))
                return InvalidAuthToken(_tokenStatus);

            var _products = _productService.SearchProducts(0, int.MaxValue, null, 0, 0, 0, 0, null, false, false, false, null, null, 0, keywords, true, true, true);

            if (_products == null || _products.Count <= 0)
                return ErrorOccured("No product was found");
            else
                return Successful(_productHelper.GetProductsJson(_products, _productPictures));
        }

P.S。新手MVC / NopCommerce

更新：我试图加载控制器，然后调用该方法，请参阅下面的代码。但是，我最终在BaseController's RenderPartialViewToString方法中收到错误。

代码：

var _shoppingCartController = DependencyResolver.Current.GetService<ShoppingCartController>();
            return _shoppingCartController.AddProductToCart_Catalog(productId, 1, quantity);

执行时出错：类型＆＃39; System.ArgumentNullException＆＃39;的例外情况发生在System.Web.Mvc.dll中但未在用户代码中处理

Additional information: Value cannot be null.

NopCommerce，在Nop.Plugins项目中调用Nop.Web控制器方法
