Amzon MWS API开发之订单接口

       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。

　　

 1     /// <summary>

 2     /// 账户信息

 3     /// </summary>

 4     [Serializable]

 5     public class AccountConfig : BaseConfig<AccountConfig>

 6     {

 7         /// <summary>

 8         /// 应用程序名称

 9         /// </summary>

10         public string AppName { get; set; }

11 

12         /// <summary>

13         /// 应用程序版本

14         /// </summary>

15         public string AppVersion { get; set; }

16 

17         /// <summary>

18         /// 账户KeyId

19         /// </summary>

20         public string AccessKeyId { get; set; }

21 

22         /// <summary>

23         /// 密钥Id

24         /// </summary>

25         public string SecretAccessKey { get; set; }

26 

27         /// <summary>

28         /// 商城Id

29         /// </summary>

30         public string MerchantId { get; set; }

31 

32         /// <summary>

33         /// 商城唯一标识Id

34         /// </summary>

35         public string MarketplaceId { get; set; }

36 

37         /// <summary>

38         /// 服务端URL

39         /// </summary>

40         public string ServiceUrl { get; set; }

41     }

　　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：

　　

 1    /// <summary>

 2         /// 获得账户信息

 3         /// </summary>

 4         protected AccountConfig Account

 5         {

 6             get

 7             {

 8                 return AccountConfig.Instance;

 9             }

10         }

11 

12         private MarketplaceWebServiceOrdersConfig GetConfig()

13         {

14             var config = new MarketplaceWebServiceOrdersConfig();

15             config.ServiceURL = Account.ServiceUrl;

16             return config;

17         }

18 

19         private MarketplaceWebServiceOrdersClient GetClient()

20         {

21             var config = this.GetConfig();

22             var client = new MarketplaceWebServiceOrdersClient(Account.AppName,

23               Account.AppVersion, Account.AccessKeyId, Account.SecretAccessKey, config);

24             return client;

25         }

26 

27         #region 获得订单列表(OrderList)

28 

29 

30         private List<Order> GetNextOrderList(ref string nextToken)

31         {

32             var client = this.GetClient();

33             var request = new ListOrdersByNextTokenRequest();

34             request.SellerId = Account.MerchantId;

35             request.NextToken = nextToken;

36 

37             var response = client.ListOrdersByNextToken(request);

38             var result = response.ListOrdersByNextTokenResult;

39             nextToken = result.NextToken;

40             List<Order> orderList = result.Orders.Order;

41 

42             return orderList;

43         }

44 

45         /// <summary>

46         /// 获得订单列表（指定Request模式）

47         /// </summary>

48         /// <param name="request">ListOrdersRequest</param>

49         /// <returns></returns>

50         public List<Order> GetOrderList(DateTime createdAfter, DateTime createdBefore)

51         {

52             var request = new ListOrdersRequest();

53             request.CreatedAfter = AmazonHelper.ConvertToISO8601(createdAfter);

54             request.CreatedBefore = AmazonHelper.ConvertToISO8601(createdBefore);

55             request.MarketplaceId = new MarketplaceIdList();

56             request.MarketplaceId.Id = new List<string> { Account.MarketplaceId };

57             request.SellerId = Account.MerchantId;

58 

59             var client = GetClient();

60             var response = client.ListOrders(request);

61             var result = response.ListOrdersResult;

62             var orderList = result.Orders.Order;

63             string nextToken = result.NextToken;

64 

65             while (!string.IsNullOrEmpty(nextToken))

66             {

67                 List<Order> tempList = GetNextOrderList(ref nextToken);

68                 orderList = orderList.Concat(tempList).ToList();

69             }

70 

71             return orderList;

72         }

73         #endregion

    切记，在调用中不要忽视了在请求参数中给 SellerId 赋值。
