Newtonsoft JSON反序列化可在本地和实时环境中使用，但不适用于ASP.NET MVC应用程序的测试

我目前正在从事一个涉及使用支付网关的项目。iframe用于保存付款网关。通过发送以下POST可以检索iframe的网址。

ResponseBody b = new ResponseBody();
b.SenderId = ConfigurationManager.AppSettings["SenderId"];
b.Username = ConfigurationManager.AppSettings["PayUsername"];
b.Password = ConfigurationManager.AppSettings["PayPassword"];
b.PaymentSessionProviderReference = transaction.TransactionRef;
b.AmountInCents = Decimal.ToInt32(purchaseDetails.CartTotal * 100);
b.ReturnURL = redirectorLink;
b.BackgroundColor = "#ffffff";
b.InlineFrame = true;
if ((string)Session["Language"] == "en-EN") { b.Language = "EN"; }

client.BaseAddress = new Uri(url);

 HttpResponseMessage response = await client.PostAsJsonAsync("PreparePayment", b);

然后，对此帖子的回复将保留指向付款网关的网址，然后在iframe中打开该网址。另外，在此POST中也指定了returnLink，在该位置上，网关将在用户输入其付款明细之后，在iframe中重定向用户。

为了让我确认付款状态以继续工作流，然后我使用returnLink属性中指定的操作方法通过另一个POST请求付款。这样做如下：

GetPaymentModel b = new GetPaymentModel();
b.SenderId = ConfigurationManager.AppSettings["SenderId"];
b.Username = ConfigurationManager.AppSettings["PayUsername"];
b.Password = ConfigurationManager.AppSettings["PayPassword"];
b.PaymentSessionProviderReference = transaction.TransactionRef;
b.MessageId = null;
b.PaymentId = null;

client.BaseAddress = new Uri(url);

HttpResponseMessage response = await client.PostAsJsonAsync("GetPayment", b);

现在这是问题开始的地方。在所有环境中都正确返回了JSON。然后，此JSON将反序列化，如下所示：

string jsonResponse = "";
jsonResponse = await response.Content.ReadAsStringAsync();
AvaLogger.WriteLog(jsonResponse);

//Yet to figure out how to log trace on the test server.
ITraceWriter traceWriter = new MemoryTraceWriter();
paymentDetails = JsonConvert.DeserializeObject<PaymentDetailsModel>(jsonResponse, 
    new JsonSerializerSettings { TraceWriter = traceWriter, Converters = { new 
    JavaScriptDateTimeConverter() }}
);

AvaLogger.WriteLog("Information For: " + paymentDetails.paymentSessionProviderReference + ". Host message: " + paymentDetails.hostMessage);

在本地和实时环境上记录此信息时，日志方法记录以下信息：

[24/06/2020 08:38:46] <PaymentResolver>d__12: MoveNext: {"transactionTypeField":0,"authorisationCodeField":"425643","batchNumberField":"","hostCodeField":"000","hostMessageField":"APPROVED","merchantAccountField":"1000","merchantTerminalField":null,"maskedCardNumberField":"444444****4444","detectedCardApplicationField":"VISA","paymentDateField":"2020-06-24T08:38:59","anyField":null,"paymentIdField":153938,"paymentSessionProviderReferenceField":"G2315","paymentStateField":3,"amountInCentsField":2000,"pGDataField":{"paymentGatewayReferenceField":"93177947","emailAddressField":"[email protected]","anyField":null,"PropertyChangedEvent":null},"assignmentsField":[],"PropertyChangedEvent":null}

 LogMode:   NotSet
 UTC TimeStamp:     24/06/2020 06:38:46

JSON已被完全检索，并且数据已正确反序列化。但是，当涉及到测试环境时，会发生以下情况：

[24/06/2020 09:48:32] <PaymentResolver>d__12: MoveNext: {"transactionTypeField":0,"authorisationCodeField":"316120","batchNumberField":"","hostCodeField":"000","hostMessageField":"APPROVED","merchantAccountField":"1000","merchantTerminalField":null,"maskedCardNumberField":"444444****4444","detectedCardApplicationField":"VISA","paymentDateField":"2020-06-24T09:48:26","anyField":null,"paymentIdField":153949,"paymentSessionProviderReferenceField":"G2333","paymentStateField":3,"amountInCentsField":500,"pGDataField":{"paymentGatewayReferenceField":"93180750","emailAddressField":"[email protected]","anyField":null,"PropertyChangedEvent":null},"assignmentsField":[],"PropertyChangedEvent":null}
 LogMode:   NotSet
 UTC TimeStamp:     24/06/2020 07:48:32
 
[24/06/2020 09:48:32] <PaymentResolver>d__12: MoveNext: Information For: . Host message: 
 LogMode:   NotSet
 UTC TimeStamp:     24/06/2020 07:48:32

JSON仍正确返回。但是，不会对数据进行反序列化。结果，paymentDetails的所有属性（在文章底部显示的PaymentDetailsModel实例）将保持为空。

是否存在某种可能与此混淆的服务器配置？感谢您的阅读，并希望这对您有足够的参考价值！

PS我正在尝试弄清楚如何打印TraceWriter实例的日志，因为在ASP.NET上处理API还是比较陌生的。

以供参考：

PaymentDetailsModel：

 public class PaymentDetailsModel
    {
        [JsonProperty("transactionTypeField", Required = Required.Default, NullValueHandling = NullValueHandling.Ignore)]
        public TransactionTypes transactionType { get; set; }

        [JsonProperty("authorisationCodeField", Required = Required.Default, NullValueHandling = NullValueHandling.Ignore)]
        public string authorisationCode { get; set; }

        public string batchNumber { get; set; }

        [JsonProperty("hostCodeField", Required = Required.Default, NullValueHandling = NullValueHandling.Ignore)]
        public string hostCode{ get; set; }

        [JsonProperty("hostMessageField", Required = Required.Default, NullValueHandling = NullValueHandling.Ignore)]
        public string hostMessage { get; set; }

        public string merchantAccount { get; set; }

        [JsonProperty("merchantTerminalField", Required = Required.Default, NullValueHandling = NullValueHandling.Ignore)]
        public string merchantTerminal { get; set; }

        [JsonProperty("maskedCardNumberField", Required = Required.Default, NullValueHandling = NullValueHandling.Ignore)]
        public string maskedCardNumber { get; set; }

        [JsonProperty("detectedCardApplicationField", Required = Required.Default, NullValueHandling = NullValueHandling.Ignore)]
        public string detectedCardApplication { get; set; }

        [JsonProperty("paymentDateField", Required = Required.Default, NullValueHandling = NullValueHandling.Ignore)]
        public string paymentDate { get; set; }

        [JsonProperty("anyField", Required = Required.Default, NullValueHandling = NullValueHandling.Ignore)]
        public object any { get; set; }

        [JsonProperty("paymentIdField", Required = Required.Default, NullValueHandling = NullValueHandling.Ignore)]
        public int paymentId { get; set; }

        [JsonProperty("paymentSessionProviderReferenceField", Required = Required.Default, NullValueHandling = NullValueHandling.Ignore)]
        public string paymentSessionProviderReference { get; set; }

        [JsonProperty("paymentStateField", Required = Required.Default, NullValueHandling = NullValueHandling.Ignore)]
        public PaymentStates paymentState { get; set; }

        [JsonProperty("amountInCentsField", Required = Required.Default, NullValueHandling = NullValueHandling.Ignore)]
        public int amountInCents { get; set; }

        [JsonProperty("pGDataField", Required = Required.Default, NullValueHandling = NullValueHandling.Ignore)]
        public PGdataModel pGData { get; set; }

        [JsonProperty("assignmentsField", Required = Required.Default, NullValueHandling = NullValueHandling.Ignore)]
        public object[] assignments { get; set; }
        public object PropertyChangedEvent { get; set; }
    }

更新：

我创建了一个控制台应用程序，以消除Web应用程序增加的复杂性，并且反序列化对于硬编码JSON字符串和从API检索的JSON都可以正常工作。这是否可以鼓励这可能是IIS配置问题呢？

因此，结果证明Web.config上发生了更改，将Newtonsoft版本从10更改为11，并且对于此……大的面部表情时刻没有引发任何错误。将版本更改为11以与其他环境匹配可以解决此问题。
