c# - PayPal Classic API 验证一个调用但不验证下一个

Question

我正在尝试从 PayPal 下载交易历史记录。为此，我调用 TransactionSearch 来获取日期范围内交易的基本列表。然后我调用 GetTransactionDetails 以获取每笔交易的完整详细信息。

        using (var client = new PayPalService.PayPalAPIInterfaceClient())
        {
            var credentials = new PayPalService.CustomSecurityHeaderType
            {
                Credentials = new PayPalService.UserIdPasswordType
                {
                    Username = "MyUserName",
                    Password = "MyPassword",
                    Signature = "MySignature"
                }
            };

            TransactionSearchReq request = new TransactionSearchReq();
            request.TransactionSearchRequest = new TransactionSearchRequestType();
            request.TransactionSearchRequest.StartDate = DateTime.Now.AddHours(-12);
            request.TransactionSearchRequest.EndDate = DateTime.Now;
            request.TransactionSearchRequest.Version = "117.0";

            TransactionSearchResponseType transactionSearchResponseType = client.TransactionSearch(ref credentials, request);
            foreach (PaymentTransactionSearchResultType t in transactionSearchResponseType.PaymentTransactions)
            {
                var reqType = new GetTransactionDetailsRequestType
                {
                    TransactionID = t.TransactionID,
                    Version = "117.0"
                };
                reqType.DetailLevel = new DetailLevelCodeType[1];
                reqType.DetailLevel[0] = DetailLevelCodeType.ReturnAll;

                var treq = new GetTransactionDetailsReq
                {
                    GetTransactionDetailsRequest = reqType
                };
                GetTransactionDetailsResponseType transaction = client.GetTransactionDetails(ref credentials, treq);
            }

        }

对 TransactionSearch 的第一次调用有效并返回了一个交易列表。第二次调用 GetTransactionDetails 返回错误:

Error Code: "10002"
Long Message: "You do not have permissions to make this API call"
Short Message: "Authentication/Authorization Failed"
Correlation ID: 67970b9729a82
Ack: Failure
Build: 000000
Version: "117.0"
Any: null
PropertyChanged: null

我已经三次检查我在调用中传递的 TransactionId 是否是我的有效交易之一，它是。

有人见过这个吗？

似乎有些凭据没有在您的代码中为给定变量传递。确保以下变量包含值:

用户名 = "我的用户名",密码 = "我的密码",Sgnature = "我的签名"

您可以对 API 凭据进行硬编码，然后尝试 .
