我如何序列化 (NewtonSoft) class，其中包含一个带有属性命名类型的接口？

Question

我需要序列化这个class（Assembly Adyen，版本=6.0.0.0）的结果：

<Runtime.Serialization.DataContractAttribute>
Public Class PaymentResponse
    Implements IEquatable(Of PaymentResponse), IValidatableObject

    Public Sub New(...)

    ...
   <Runtime.Serialization.DataMemberAttribute(Name:="action", EmitDefaultValue:=False)>
    Public Property Action As IPaymentResponseAction

    ...        

End Class

查看结果，我有预期的 Action.PaymentData、Action.PaymentMethodType、Action.Token、Action.[Type] 和 Action.Url： Screenshot of Autos

但是当我序列化结果时，

Dim tmp As String = Newtonsoft.Json.JsonConvert.SerializeObject(ret, GetType(PaymentResponse), New 
                     Newtonsoft.Json.JsonSerializerSettings() With {.[Error] = AddressOf jsonerror})

我只得到：

{
  "resultCode": "IdentifyShopper",
  "action": {
  "paymentData": "XXX",
  "paymentMethodType": "scheme",
  "token": "YYY"
},
"authentication": {
"threeds2.fingerprintToken": "ZZZ"
},
"details": [
 {
  "key": "threeds2.fingerprint",
  "type": "text"
 }
],
"paymentData": "QQQ"
}

我没有收到操作。[在我的 Json 字符串中输入 [Type] 和“Action.Url”。

jsonerror()

从未被击中。

编辑：我添加了一个跟踪器：

Dim tracewriter As Newtonsoft.Json.Serialization.ITraceWriter = New 
                      Newtonsoft.Json.Serialization.MemoryTraceWriter
Dim tmp As String = Newtonsoft.Json.JsonConvert.SerializeObject(ret, 
                      GetType(PaymentResponse), New 
                      Newtonsoft.Json.JsonSerializerSettings() With 
                     {.TraceWriter = tracewriter, .[Error] = AddressOf 
                        jsonerror})

一切看起来都很好，除了我没有采取行动。[type] 序列化：

Answer 1

这是 Adyen .NET 库中的错误。 IPaymentResponseAction 的实现类缺少 DataMember 注释。有一个 fix 准备合并，将很快在下一个补丁版本中提供。建议发布时更新补丁版本

对于 URL 字段，它仅适用于重定向等特定操作，例如理想的付款方式。对于方案，如您的情况，URL 不适用。
