Amzon MWS API開發之訂單接口

       Amazon訂單接口是Amazon MWS 開發接口中的一大塊，我們可以通過接口調用來獲得訂單數據。

　　 在調用接口之前，首先我們要獲得相關店鋪商家的店鋪密鑰等信息。如下：

      在此我將所有信息定義在一個類中，采用序列化的方式，方便存取值。

　　

    /// <summary>
    /// 賬戶信息
    /// </summary>
    [Serializable]
    public class AccountConfig : BaseConfig<AccountConfig>
    {
        /// <summary>
        /// 應用程序名稱
        /// </summary>
        public string AppName { get; set; }

        /// <summary>
        /// 應用程序版本
        /// </summary>
        public string AppVersion { get; set; }

        /// <summary>
        /// 賬戶KeyId
        /// </summary>
        public string AccessKeyId { get; set; }

        /// <summary>
        /// 密鑰Id
        /// </summary>
        public string SecretAccessKey { get; set; }

        /// <summary>
        /// 商城Id
        /// </summary>
        public string MerchantId { get; set; }

        /// <summary>
        /// 商城唯一標識Id
        /// </summary>
        public string MarketplaceId { get; set; }

        /// <summary>
        /// 服務端URL
        /// </summary>
        public string ServiceUrl { get; set; }
    }

 

　　然后我們回到文檔中，我們會發現，請求參數中，有兩個參數是必填的：CreatedAfter、MarketplaceId。調用接口的方法很簡單，無非是構造完整的對象，其實主要還是保持必填參數的完整性，這次我們拿ListOrder 接口來舉例：

　　

   /// <summary>
        /// 獲得賬戶信息
        /// </summary>
        protected AccountConfig Account
        {
            get
            {
                return AccountConfig.Instance;
            }
        }

        private MarketplaceWebServiceOrdersConfig GetConfig()
        {
            var config = new MarketplaceWebServiceOrdersConfig();
            config.ServiceURL = Account.ServiceUrl;
            return config;
        }

        private MarketplaceWebServiceOrdersClient GetClient()
        {
            var config = this.GetConfig();
            var client = new MarketplaceWebServiceOrdersClient(Account.AppName,
              Account.AppVersion, Account.AccessKeyId, Account.SecretAccessKey, config);
            return client;
        }

        #region 獲得訂單列表(OrderList)


        private List<Order> GetNextOrderList(ref string nextToken)
        {
            var client = this.GetClient();
            var request = new ListOrdersByNextTokenRequest();
            request.SellerId = Account.MerchantId;
            request.NextToken = nextToken;

            var response = client.ListOrdersByNextToken(request);
            var result = response.ListOrdersByNextTokenResult;
            nextToken = result.NextToken;
            List<Order> orderList = result.Orders.Order;

            return orderList;
        }

        /// <summary>
        /// 獲得訂單列表（指定Request模式）
        /// </summary>
        /// <param name="request">ListOrdersRequest</param>
        /// <returns></returns>
        public List<Order> GetOrderList(DateTime createdAfter, DateTime createdBefore)
        {
            var request = new ListOrdersRequest();
            request.CreatedAfter = AmazonHelper.ConvertToISO8601(createdAfter);
            request.CreatedBefore = AmazonHelper.ConvertToISO8601(createdBefore);
            request.MarketplaceId = new MarketplaceIdList();
            request.MarketplaceId.Id = new List<string> { Account.MarketplaceId };
            request.SellerId = Account.MerchantId;

            var client = GetClient();
            var response = client.ListOrders(request);
            var result = response.ListOrdersResult;
            var orderList = result.Orders.Order;
            string nextToken = result.NextToken;

            while (!string.IsNullOrEmpty(nextToken))
            {
                List<Order> tempList = GetNextOrderList(ref nextToken);
                orderList = orderList.Concat(tempList).ToList();
            }

            return orderList;
        }
        #endregion

      

    切記，在調用中不要忽視了在請求參數中給 SellerId 賦值。
