为什么我从 ASP.net Core 2.2 调用的 SOAP 调用返回 null 结果？

Question

I'm having an issue where some SOAP calls are returning null objects in ASP.netCore 2.2. I appreciate any help that anyone can give, I'm not getting much support from the vendor and I know this may be a lot to ask.

I'm able to make some calls successfully and get expected results. Other calls are received by the API successfully (for example I can post data to the API), and return results in SOAP UI, but in my ASP.net application the return objects are null. I've confirmed that the data I'm sending works. The result does contain the expected model types, but the contents of the models are null.

The call that works returns a simple model, the call that doesn't work has a more complicated return type. I suspect that is the important difference, but I can't see anywhere to debug how things go wrong. The result process does hit the constructor for the return object, but it hits the empty constructor, not the one that I'd expect to return the value. I don't know if that's an issue or not, or how to troubleshoot it. I also have my doubts about the namespace in use on the WSDL code. I can't resolve that address, so it it's used for deserialization it seems like that would be an issue. Do I need to add that to my project somehow?

The code for the API calls is generated by a WSDL. I'm new to SOAP APIs and WSDLs, so this has been tough so far. There's unfortunately a lot happening here that I don't understand but I hope i'm close since I can get some calls to work. Much of appears to be 'black-box' as far as I'm concerned. I'm not sure where else to turn.

Here is the call that works successfully:

My call that works:

var task = await cardManagementEPClient.getCardAsync(EFSConnection.ClientID, testCardNumber);

My call that returns a null result:

var task = await cardManagementEPClient.getPayrollCashHistoryAsync(EFSConnection.ClientID, cardNumber, beginDate, DateTime.Now);

The WSDL interface for the calls:

namespace Project.EFS.Interfaces
{    
    [System.ServiceModel.ServiceContractAttribute(Namespace = "http://com.tch.cards.service", ConfigurationName = "CardManagementEP")]
    public interface ICardManagementEP
    {
        [System.ServiceModel.OperationContractAttribute(Action = "", ReplyAction = "*")]
        [System.ServiceModel.XmlSerializerFormatAttribute(Style = System.ServiceModel.OperationFormatStyle.Rpc, SupportFaults = true)]
        [return: System.ServiceModel.MessageParameterAttribute(Name = "result")]
        System.Threading.Tasks.Task<WSCard> getCardAsync(string clientId, string cardNumber);

        [System.ServiceModel.OperationContractAttribute(Action = "", ReplyAction = "*")]
        [System.ServiceModel.XmlSerializerFormatAttribute(SupportFaults = true)]
        System.Threading.Tasks.Task<getPayrollCashHistoryResponse> getPayrollCashHistoryAsync(getPayrollCashHistoryRequest request);
//Additional methods omitted for brevity
}

The WSDL interface implementation:

namespace Project.EFS
{
    [System.ServiceModel.ServiceContractAttribute(Namespace = "http://com.tch.cards.service", ConfigurationName = "CardManagementEP")]
    public partial class CardManagementEPClient : System.ServiceModel.ClientBase<ICardManagementEP>, ICardManagementEP
    {
        public System.Threading.Tasks.Task<WSCard> getCardAsync(string clientId, string cardNumber)
        {
            return base.Channel.getCardAsync(clientId, cardNumber);
        }



[System.ComponentModel.EditorBrowsableAttribute(System.ComponentModel.EditorBrowsableState.Advanced)]
        System.Threading.Tasks.Task<getPayrollCashHistoryResponse> ICardManagementEP.getPayrollCashHistoryAsync(getPayrollCashHistoryRequest request)
        {
            return base.Channel.getPayrollCashHistoryAsync(request);
        }

        public System.Threading.Tasks.Task<getPayrollCashHistoryResponse> getPayrollCashHistoryAsync(string clientId, string cardNumber, System.DateTime begDate, System.DateTime endDate)
        {
            getPayrollCashHistoryRequest inValue = new getPayrollCashHistoryRequest();
            inValue.clientId = clientId;
            inValue.cardNumber = cardNumber;
            inValue.begDate = begDate;
            inValue.endDate = endDate;
            return ((ICardManagementEP)(this)).getPayrollCashHistoryAsync(inValue);
        }

    //Additional methods omitted for brevity
    }
}

The WSDL models:

namespace Project.EFS.Models
{
[System.Xml.Serialization.XmlTypeAttribute(Namespace = "http://com.tch.cards.service/types")]
    public partial class WSCard
    {

        private string cardNumberField;


        [System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified, IsNullable = true, Order = 0)]
        public string cardNumber
        {
            get
            {
                return this.cardNumberField;
            }
            set
            {
                this.cardNumberField = value;
            }
        }
        //Additional fields, getters, and setters omitted
    }

[System.Xml.Serialization.XmlTypeAttribute(Namespace = "http://com.tch.cards.service/types")]
    public partial class WSCashRecord
    {

        private double amountField;

        [System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified, Order = 0)]
        public double amount
        {
            get
            {
                return this.amountField;
            }
            set
            {
                this.amountField = value;
            }
        }
        //Additional fields, getters, and setters omitted
    }
}

namespace Project.EFS.Methods
{
[System.ComponentModel.EditorBrowsableAttribute(System.ComponentModel.EditorBrowsableState.Advanced)]
    [System.ServiceModel.MessageContractAttribute(WrapperName = "getPayrollCashHistoryResponse", WrapperNamespace = "http://com.tch.cards.service", IsWrapped = true)]
    public partial class getPayrollCashHistoryResponse
    {

        [System.ServiceModel.MessageBodyMemberAttribute(Namespace = "", Order = 0)]
        [System.Xml.Serialization.XmlArrayAttribute()]
        [System.Xml.Serialization.XmlArrayItemAttribute("value", Form = System.Xml.Schema.XmlSchemaForm.Unqualified)]
        public WSCashRecord[] resultWSCashRecord;

        public getPayrollCashHistoryResponse()
        {
        }

        public getPayrollCashHistoryResponse(WSCashRecord[] result)
        {
            this.resultWSCashRecord = result;
        }
    }
}

Answer 1

I could be blind but I dont see anything in your WSDL etc for getCurrentCashAllAmountsAsync

I see it for getCardAsync and getCashHistoryAsync
