     Amazon订单接口是Amazon MWS 开发接口中的一大块,我们可以通过接口调用来获得订单数据。

   在调用接口之前,首先我们要获得相关店铺商家的店铺密钥等信息。如下:

      在此我将所有信息定义在一个类中,采用序列化的方式,方便存取值。

/// <summary>
    /// 账户信息
    /// </summary>
    [Serializable]
    public class AccountConfig : BaseConfig<AccountConfig>
    {
        /// <summary>
        /// 应用程序名称
        /// </summary>
        public string AppName { get; set; }

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

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

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

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

        /// <summary>
        /// 商城唯一标识Id
        /// </summary>
        public string MarketplaceId { get; set; }

        /// <summary>
        /// 服务端URL
        /// </summary>
        public string ServiceUrl { get; set; }
    }

然后我们回到文档中,我们会发现,请求参数中,有两个参数是必填的:CreatedAfter、MarketplaceId。调用接口的方法很简单,无非是构造完整的对象,其实主要还是保持必填参数的完整性,这次我们拿ListOrder 接口来举例:

  

/// <summary>
        /// 获得账户信息
        /// </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 获得订单列表(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>
        /// 获得订单列表(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

    切记,在调用中不要忽视了在请求参数中给 SellerId 赋值。
