我正在尝试使用 ksoap2 从 android 访问 wcf soap 服务中的方法。 我能够成功地将简单的类型参数传递给该方法，它工作正常。 但是当我尝试传递对象时，wcf 方法接收到的所有对象值都是 0。

我在 WP7 应用程序中使用了相同的 SOAP 服务，它运行良好。

我的服务中有 2 个方法，ksoapadd 和 addParam。 addParam 接受两个整数并返回它们的总和(这有效)。 ksoapadd 接受类 testadd 的一个对象，它有两个整数元素，ksoapadd 返回它们的总和(这获取并发送 0)。

我认为它与 namespace 有关，但我不知道如何解决它。我一直在反复试验以使 soap 请求正确，但还没有成功。

谁能帮我弄清楚该怎么做？我尝试了很多选择，这些选择以某种方式帮助了其他遇到类似问题但无济于事的人。

这是我使用 ksoap2 的 java 代码:

private static final String NAMESPACE = "http://tempuri.org/";
private static final String URL = "http://10.0.2.2:51086/Service1.svc?wsdl";
private static final String SOAP_ACTION4 = "http://tempuri.org/IService1/ksoapAdd";
private static final String METHOD_NAME4 = "ksoapAdd";
private static final String SOAP_ACTION5 = "http://tempuri.org/IService1/addParam";
private static final String METHOD_NAME5 = "addParam";

try {
    testadd numX = new testadd(25,25);

    SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME4);

    PropertyInfo prop = new PropertyInfo();
    prop.setNamespace(NAMESPACE);
    prop.setName("num1");
    prop.setType(numX.getClass());
    prop.setValue(numX);
    Request.addProperty(prop);

    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.dotNet = true;
    envelope.setOutputSoapObject(Request);

    envelope.implicitTypes = true;

    HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
    androidHttpTransport.debug=true;
    androidHttpTransport.call(SOAP_ACTION4, envelope);

    Log.d(logtag + " request dump", androidHttpTransport.requestDump);
    Log.d(logtag + " response dump", androidHttpTransport.responseDump);

    final SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
    final int num = Integer.parseInt(response.toString());

    } catch (Exception e) 
    {
        e.printStackTrace();
    }

这是我的 java 类 testadd:

import java.util.Hashtable;
import org.ksoap2.serialization.KvmSerializable;
import org.ksoap2.serialization.PropertyInfo;

public class testadd implements KvmSerializable{
int number1;
int number2;

testadd(){}
testadd(int a, int b){ number1 = a; number2 = b;}


@Override
public Object getProperty(int arg0) {
    switch(arg0)
    {
    case 0:
        return number1;
    case 1:
        return number2;

    }

return null;
}

@Override
public int getPropertyCount() {

    return 2;
}

@Override
public void getPropertyInfo(int arg0, Hashtable arg1, PropertyInfo arg2) {

     switch(arg0)
        {
        case 0:
            arg2.type = PropertyInfo.INTEGER_CLASS;
            arg2.name = "number_1";
            break;
        case 1:
            arg2.type = PropertyInfo.INTEGER_CLASS;
            arg2.name = "number_2";
            break;

        default:break;
        }

}

@Override
public void setProperty(int arg0, Object value) {

    switch(arg0)
    {
    case 0:
       number1 = Integer.parseInt(value.toString());
        break;
    case 1:
        number2 = Integer.parseInt(value.toString());
        break;

    default:
        break;
    }
}
}

服务代码:

<ServiceContract()> _
Public Interface IService1
<OperationContract()> _
Function ksoapAdd(ByVal num1 As testadd) As Integer

<OperationContract()> _
Function addParam(ByVal num1 As Integer, ByVal num2 As Integer) As Integer

End Interface

<DataContract()> _
Public Class testadd
Private number1 As Integer
Private number2 As Integer

<DataMember()> _
Public Property number_1() As Integer
    Get
        Return number1
    End Get
    Set(ByVal value As Integer)
        number1 = value
    End Set
End Property

<DataMember()> _
Public Property number_2() As Integer
    Get
        Return number2
    End Get
    Set(ByVal value As Integer)
        number2 = value
    End Set
End Property

End Class

服务方式:

Public Function ksoapAdd(ByVal num1 As testadd) As Integer Implements IService1.ksoapAdd
    MsgBox(num1.number_1)
    Return num1.number_1 + num1.number_2
End Function

Public Function addParam(ByVal num1 As Integer, ByVal num2 As Integer) As Integer Implements IService1.addParam
    MsgBox(num1 + num2)
    Return num1 + num2
End Function

我知道这是很多代码，但它认为有必要了解整个画面。

谢谢!

最佳答案

我终于让它工作了!

原来我的 android ksoap2 代码不喜欢 WCF 在 SOAP 服务中设置的默认命名空间 (tempuri.org)。

我的猜测是，使用默认命名空间，请求信封无法将传递的 testadd 对象映射到服务中定义了 testadd 类的数据协定。通过为 WCF 服务中的服务契约(Contract)和数据契约(Contract)显式定义命名空间，这会更改/重新排列 wsdl 并使数据契约(Contract)可访问。

我按照本教程摆脱了 tempuri.org 命名空间- http://blogs.msdn.com/b/endpoint/archive/2011/05/12/how-to-eliminate-tempuri-org-from-your-service-wsdl.aspx

我在服务代码(VB)的适当位置添加了以下内容

<ServiceContract(Namespace:="http://wcfservicetest.org/Service1")> _
<DataContract(Namespace:="http://wcfservicetest.org/Service1")> _
<ServiceBehavior(Namespace:="http://wcfservicetest.org/Service1")> _

我将命名空间更改为“http://wcfservicetest.org/Service1”，并使用新命名空间在 android java 代码中编辑了 NAMESPACE 和 SOAP_ACTION。

这样做之后我得到了我想要的结果!

这是 soap 请求:

<v:Envelope xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns:d="http://www.w3.org/2001/XMLSchema" xmlns:c="http://schemas.xmlsoap.org/soap/encoding/" xmlns:v="http://schemas.xmlsoap.org/soap/envelope/">
<v:Header />
<v:Body>
<ksoapAdd xmlns="http://wcfservicetest.org/Service1" id="o0" c:root="1">
<n0:num1 xmlns:n0="http://wcfservicetest.org/Service1">
<number_1>25</number_1>
<number_2>25</number_2>
</n0:num1>
</ksoapAdd>
</v:Body>
</v:Envelope>

SOAP react :

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Body>
<ksoapAddResponse xmlns="http://wcfservicetest.org/Service1">
<ksoapAddResult>50</ksoapAddResult>
</ksoapAddResponse>
</s:Body>
</s:Envelope>

所以我建议任何其他使用 ksoap2 学习 SOAP 服务的人，不要使用默认命名空间，设置你自己的命名空间。我浪费了一个星期的时间来解决这个问题。

希望有一天这对某人有所帮助!!
