{/// summary/// 商品对象/// /summary[OrchardFeature(Aivics.Commerce)]public class ProductPart : ContentPartProductPartRecord, IProduct {/// summary/// 商品SKU/// /summary[Required]public string Sku{get { return Retrieve(r r.Sku); }set { Store(r r.Sku, value); }}/// summary/// 价格/// /summary[Required]public double Price{get { return Retrieve(r r.Price); }set { Store(r r.Price, value); }}/// summary/// 折扣价/// /summarypublic double DiscountPrice{get { return Retrieve(r r.DiscountPrice, -1); }set { Store(r r.DiscountPrice, value); }}/// summary/// 数字商品、虚拟商品没有物流/// /summarypublic bool IsDigital{get { return Retrieve(r r.IsDigital); }set { Store(r r.IsDigital, value); }}/// summary/// 物流费用 -不填写时将使用物流费用模板进行计算/// /summarypublic double?

}2. 套餐商品类 目前UI菜单中不公布此功能与流程调试中 /// summary/// 产品套餐/// /summarypublic class BundlePart : ContentPartBundlePartRecord{public IEnumerableint ProductIds{get { return Record.Products.Select(p p.ContentItemRecord.Id); }}public IEnumerableProductQuantity ProductQuantities{get{returnRecord.Products.Select(p new ProductQuantity{Quantity p.Quantity,ProductId p.ContentItemRecord.Id});}}}二。物流计费方案模块 说明 该模块为商品所需运费自动匹配计算的功能 如果商品中指定了【运费】金额则不从此处计算运费。 目前支持 【重量计算规则】和【大小规格计算】 有效区域应为 所有省份 目前仅提供几个周边省份测试数据 实体的相关代码 namespace Aivics.Commerce.Models
{/// summary/// 基于重量的物流计费/// /summarypublic class WeightBasedShippingMethodPart : ContentPartWeightBasedShippingMethodPartRecord,IShippingMethod{public string Name{get { return Retrieve(r r.Name); }set { Store(r r.Name, value); }}public string ShippingCompany{get { return Retrieve(r r.ShippingCompany); }set { Store(r r.ShippingCompany, value); }}public double Price{get { return Retrieve(r r.Price); }set { Store(r r.Price, value); }}public string IncludedShippingAreas{get { return Retrieve(r r.IncludedShippingAreas); }set { Store(r r.IncludedShippingAreas, value); }}public string ExcludedShippingAreas{get { return Retrieve(r r.ExcludedShippingAreas); }set { Store(r r.ExcludedShippingAreas, value); }}public double? MinimumWeight{get { return Retrieve(r r.MinimumWeight); }set { Store(r r.MinimumWeight, value); }}public double? MaximumWeight{get { return Retrieve(r r.MaximumWeight); }set { Store(r r.MaximumWeight, value); }} // Set to double.PositiveInfinity (the default) for unlimited weight rangespublic IEnumerableShippingOption ComputePrice(IEnumerableShoppingCartQuantityProduct productQuantities,IEnumerableIShippingMethod shippingMethods,string country,string zipCode,IWorkContextAccessor workContextAccessor){var quantities productQuantities.ToList();var fixedCost quantities.Where(pq pq.Product.ShippingCost ! null pq.Product.ShippingCost 0 !pq.Product.IsDigital).Sum(pq pq.Quantity * (double)pq.Product.ShippingCost);var weight quantities.Where(pq (pq.Product.ShippingCost null || pq.Product.ShippingCost 0) !pq.Product.IsDigital).Sum(pq pq.Quantity * pq.Product.Weight);if (weight.CompareTo(0) 0){yield return GetOption(fixedCost);}else if (weight MinimumWeight weight MaximumWeight){yield return GetOption(fixedCost Price);}}private ShippingOption GetOption(double price){return new ShippingOption{Description Name,Price price,IncludedShippingAreas IncludedShippingAreas null? new string[] { }: IncludedShippingAreas.Split(new[] { , }, StringSplitOptions.RemoveEmptyEntries),ExcludedShippingAreas ExcludedShippingAreas null? new string[] { }: ExcludedShippingAreas.Split(new[] { , }, StringSplitOptions.RemoveEmptyEntries)};}}
} 三。商品阶梯价格 说明可设置一个全局的阶梯价格表 满立减的规则 同时商品可以对此进行覆盖 如果需要做定期的促销类活动则可使用下面一个模块。。。。 public class TieredPriceProvider : ITieredPriceProvider{private readonly IWorkContextAccessor _wca;public TieredPriceProvider(IWorkContextAccessor wca){_wca wca;}public ShoppingCartQuantityProduct GetTieredPrice(ShoppingCartQuantityProduct quantityProduct){var priceTiers GetPriceTiers(quantityProduct.Product);var priceTier priceTiers ! null ? priceTiers.Where(t t.Quantity quantityProduct.Quantity).OrderByDescending(t t.Quantity).Take(1).SingleOrDefault() : null;if (priceTier ! null){quantityProduct.Price (double)priceTier.Price;}return quantityProduct;}public IEnumerablePriceTier GetPriceTiers(ProductPart product){var productSettings _wca.GetContext().CurrentSite.AsProductSettingsPart();IEnumerablePriceTier priceTiers null;ListPriceTier adjustedPriceTiers new ListPriceTier();if (productSettings.AllowProductOverrides product.OverrideTieredPricing){priceTiers product.PriceTiers;}else if (productSettings.DefineSiteDefaults (!productSettings.AllowProductOverrides || !product.OverrideTieredPricing)){priceTiers productSettings.PriceTiers;}if (priceTiers null)return priceTiers;foreach (var tier in priceTiers){var adjustedPrice tier.Price;if (tier.Price null tier.PricePercent ! null){adjustedPrice product.Price * (double)tier.PricePercent / 100;}adjustedPriceTiers.Add(new PriceTier{Price adjustedPrice,Quantity tier.Quantity,PricePercent tier.PricePercent});}return adjustedPriceTiers.OrderBy(t t.Quantity);}} 四。促销模块 说明目前提供一个促销模块规则 主要为满立减活动等适用。 1.可设置折扣的比例9折等和固定的折扣金额 2.指定参与的时间 3.可参加此活动的角色高级会员 4.有效数量区间 5.URL匹配可以设置与指定特定的商品参加。。 主要代码如下 目前继承自IPromotion类之后相关其他活动促销规则可从此直接继承。如买10赠1活动设置等 public class Discount : IPromotion{private readonly IWorkContextAccessor _wca;private readonly IClock _clock;public Discount(IWorkContextAccessor wca, IClock clock){_wca wca;_clock clock;}public DiscountPart DiscountPart { get; set; }public IContent ContentItem { get { return DiscountPart.ContentItem; } }public string Name { get { return DiscountPart null ? Discount : DiscountPart.Name; } }public bool Applies(ShoppingCartQuantityProduct quantityProduct, IEnumerableShoppingCartQuantityProduct cartProducts){if (DiscountPart null) return false;var now _clock.UtcNow;if (DiscountPart.StartDate ! null DiscountPart.StartDate now) return false;if (DiscountPart.EndDate ! null DiscountPart.EndDate now) return false;if (DiscountPart.StartQuantity ! null DiscountPart.StartQuantity quantityProduct.Quantity)return false;if (DiscountPart.EndQuantity ! null DiscountPart.EndQuantity quantityProduct.Quantity)return false;if (!string.IsNullOrWhiteSpace(DiscountPart.Pattern) || !string.IsNullOrWhiteSpace(DiscountPart.ExclusionPattern)){string path null;if (DiscountPart.DisplayUrlResolver ! null){path DiscountPart.DisplayUrlResolver(quantityProduct.Product);}else if (_wca.GetContext().HttpContext ! null){var urlHelper new UrlHelper(_wca.GetContext().HttpContext.Request.RequestContext);path urlHelper.ItemDisplayUrl(quantityProduct.Product);}else{var autoroutePart quantityProduct.Product.AsAutoroutePart();if (autoroutePart ! null){path / autoroutePart.Path; }}if (path null) return false;if (!string.IsNullOrWhiteSpace(DiscountPart.Pattern)){var patternExpression new Regex(DiscountPart.Pattern, RegexOptions.Singleline | RegexOptions.IgnoreCase);if (!patternExpression.IsMatch(path))return false;}if (!string.IsNullOrWhiteSpace(DiscountPart.ExclusionPattern)){var exclusionPatternExpression new Regex(DiscountPart.ExclusionPattern,RegexOptions.Singleline | RegexOptions.IgnoreCase);if (exclusionPatternExpression.IsMatch(path))return false;}}if (DiscountPart.Roles.Any()){var user _wca.GetContext().CurrentUser;if (!user.HasIUserRoles()) return false;var roles user.AsIUserRoles().Roles;if (!roles.Any(r DiscountPart.Roles.Contains(r))) return false;}return true;}public ShoppingCartQuantityProduct Apply(ShoppingCartQuantityProduct quantityProduct, IEnumerableShoppingCartQuantityProduct cartProducts){if (DiscountPart null) return quantityProduct;var comment DiscountPart.Comment; var percent DiscountPart.DiscountPercent;if (percent ! null){return new ShoppingCartQuantityProduct(quantityProduct.Quantity, quantityProduct.Product, quantityProduct.AttributeIdsToValues){Comment comment,Price Math.Round(quantityProduct.Price * (1 - ((double)percent / 100)), 2),Promotion DiscountPart};}var discount DiscountPart.Discount;if (discount ! null){return new ShoppingCartQuantityProduct(quantityProduct.Quantity, quantityProduct.Product, quantityProduct.AttributeIdsToValues){Comment comment,Price Math.Round(Math.Max(0, quantityProduct.Price - (double)discount), 2),Promotion DiscountPart};}return quantityProduct;}} 五。商品扩展模块 主要为解决需要 用户确定附属配置的 商品 。 用户可在选择了主商品的基础上 选择额外配置 不同的配置将决定追加的金额不同。 这个功能需与购物车整合体现 namespace Aivics.Commerce.Models
{/// summary/// 商品扩展插件对象 用户可选择不同的插件需支付额外的插件价格/// /summarypublic class ProductAttributePart : ContentPartProductAttributePartRecord{public IEnumerableProductAttributeValue AttributeValues{get{return ProductAttributeValue.DeserializeAttributeValues(AttributeValuesString);}set{AttributeValuesString ProductAttributeValue.SerializeAttributeValues(value);}}/// summary/// 排序号/// /summary[DisplayName(Sort Order)]public int SortOrder{get { return Retrieve(r r.SortOrder); }set { Store(r r.SortOrder, value); }}/// summary/// 显示名/// /summary[DisplayName(Display Name)]public string DisplayName{get { return Retrieve(r r.DisplayName); }set { Store(r r.DisplayName, value); }}/// summary/// 设置信息/// /summaryinternal string AttributeValuesString{get{return Retrieve(r r.AttributeValues);}set{Store(r r.AttributeValues, value);}}}
} 六。订单管理 查看所有用户下单等。 七。购物车模块设置 除了domain/cart为进入购物车页面外 购物车模块已经做成widget. 可以做到layout的其中一个位置固定。 购物车相关代码 [OrchardFeature(Aivics.Commerce)]public class ShoppingCart : IShoppingCart{private readonly IContentManager _contentManager;private readonly IShoppingCartStorage _cartStorage;private readonly IPriceService _priceService;private readonly IEnumerableIProductAttributesDriver _attributesDrivers;private readonly INotifier _notifier;private IEnumerableShoppingCartQuantityProduct _products;public ShoppingCart(IContentManager contentManager,IShoppingCartStorage cartStorage,IPriceService priceService,IEnumerableIProductAttributesDriver attributesDrivers,INotifier notifier){_contentManager contentManager;_cartStorage cartStorage;_priceService priceService;_attributesDrivers attributesDrivers;_notifier notifier;T NullLocalizer.Instance;}public Localizer T { get; set; }public IEnumerableShoppingCartItem Items{get { return ItemsInternal.AsReadOnly(); }}private ListShoppingCartItem ItemsInternal{get{return _cartStorage.Retrieve();}}/// summary/// 添加商品至购物车中目前将商品存放在session中/// /summary/// param nameproductId/param/// param namequantity/param/// param nameattributeIdsToValues/parampublic void Add(int productId, int quantity 1, IDictionaryint, ProductAttributeValueExtended attributeIdsToValues null){if (!ValidateAttributes(productId, attributeIdsToValues)){// 将该商品添加到购物车时该商品扩展属性不正确或后台有更新或前台数据结构异常。_notifier.Warning(T(Couldnt add this product because of invalid attributes. Please refresh the page and try again.));return;}var item FindCartItem(productId, attributeIdsToValues);if (item ! null){item.Quantity quantity;}else{ItemsInternal.Insert(0, new ShoppingCartItem(productId, quantity, attributeIdsToValues));}_products null;}/// summary/// 查找一个商品 可以通过商品id直接从查询或者也需同时传递扩展属性进行匹配/// /summary/// param nameproductId/param/// param nameattributeIdsToValues/param/// returns/returnspublic ShoppingCartItem FindCartItem(int productId, IDictionaryint, ProductAttributeValueExtended attributeIdsToValues null){if (attributeIdsToValues null || attributeIdsToValues.Count 0){return Items.FirstOrDefault(i i.ProductId productId (i.AttributeIdsToValues null || i.AttributeIdsToValues.Count 0));}return Items.FirstOrDefault(i i.ProductId productId i.AttributeIdsToValues ! null i.AttributeIdsToValues.Count attributeIdsToValues.Count i.AttributeIdsToValues.All(attributeIdsToValues.Contains));}/// summary/// 验证该商品扩展属性是否正确或后台有更新或前台数据结构异常。/// /summary/// param nameproductId/param/// param nameattributeIdsToValues/param/// returns/returnsprivate bool ValidateAttributes(int productId, IDictionaryint, ProductAttributeValueExtended attributeIdsToValues){if (_attributesDrivers null ||attributeIdsToValues null ||!attributeIdsToValues.Any()) return true;var product _contentManager.Get(productId);return _attributesDrivers.All(d d.ValidateAttributes(product, attributeIdsToValues));}/// summary/// 批量添加商品至购物车/// /summary/// param nameitems/parampublic void AddRange(IEnumerableShoppingCartItem items){foreach (var item in items){Add(item.ProductId, item.Quantity, item.AttributeIdsToValues);}}/// summary/// 移除购物车商品/// /summary/// param nameproductId/param/// param nameattributeIdsToValues/parampublic void Remove(int productId, IDictionaryint, ProductAttributeValueExtended attributeIdsToValues null){var item FindCartItem(productId, attributeIdsToValues);if (item null) return;ItemsInternal.Remove(item);_products null;}/// summary/// 获取目前选购的商品 1.数量0, 2. 重新从服务器匹配商品避免商品被删除脏数据。/// /summary/// returns/returnspublic IEnumerableShoppingCartQuantityProduct GetProducts(){if (_products ! null) return _products;//从session中获得所有保存的商品ID (用户购物车)var ids Items.Select(x x.ProductId);var productParts _contentManager.GetManyProductPart(ids, VersionOptions.Published,new QueryHints().ExpandPartsTitlePart, ProductPart, AutoroutePart()).ToArray();var productPartIds productParts.Select(p p.Id);//保证Session中存储的ID是 服务器端 在用的Product对象 排除掉未发布删除等避免脏数据var shoppingCartQuantities (from item in Itemswhere productPartIds.Contains(item.ProductId) item.Quantity 0select new ShoppingCartQuantityProduct(item.Quantity, productParts.First(p p.Id item.ProductId), item.AttributeIdsToValues)) //使用ShoppingCartQuantityProduct完善的购物车商品字段等信息.ToList();//返回所有0选购条数的商品return _products shoppingCartQuantities.Select(q _priceService.GetDiscountedPrice(q, shoppingCartQuantities)).Where(q q.Quantity 0).ToList();}/// summary/// 更新购物车数据删除数量为0的数据 *疑问点*/// /summarypublic void UpdateItems(){ItemsInternal.RemoveAll(x x.Quantity 0);_products null;}/// summary/// 获得总价格/// /summary/// returns/returnspublic double Subtotal(){return Math.Round(GetProducts().Sum(pq Math.Round(pq.Price * pq.Quantity pq.LinePriceAdjustment, 2)), 2);}/// summary/// 总价/// /summary/// param namesubTotal/param/// returns/returnspublic double Total(double subTotal 0){if (subTotal.Equals(0)){subTotal Subtotal();}return subTotal;}/// summary/// 购买总数/// /summary/// returns/returnspublic double ItemCount(){return Items.Sum(x x.Quantity);}/// summary/// 清空/// /summarypublic void Clear(){_products null;ItemsInternal.Clear();UpdateItems();}} 目前购物车使用 Session存储。 八。商品列表详情 商品的列表与详情我们完全可以借助于orchard本身的模块实现 简单介绍。。具体可查询 orchard Projection 等相关 一。创建筛选 可理解为创建分页查询与筛选语句等。。 二。创建Projection或者Projection Widget 转载于:https://www.cnblogs.com/cuiyangMJ/p/5903875.html
