使用ksoap2从android传递对象到wcf soap服务;它发送和接收0

2019-09-27 10:24:56 作者：互联网

我试图使用ksoap2来访问来自android的wcf soap服务中的方法.
我能够成功地将简单类型参数传递给方法,它工作正常.
但是当我尝试传递对象时,wcf方法对所有对象值都接收0.

我在WP7应用程序中使用了相同的SOAP服务,运行正常.

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(这是有效的). ksoapadd接受类testadd的对象,它有两个整数元素,ksoapadd返回它们的总和(这得到并发送0).

我认为这与命名空间有关,但我无法弄清楚如何解决它.我一直在做试验和错误,以获得正确的肥皂请求,但没有运气.

任何人都可以帮我弄清楚该怎么办？我尝试了很多选项,以某种方式帮助其他有类似问题的人,但无济于事.

这是我的wsdl：

这是我的xsd2：

这是我的肥皂要求：

</v:Envelope>

肥皂反应：

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Body>
<ksoapAddResponse xmlns="http://tempuri.org/">
<ksoapAddResult>0</ksoapAddResult>
</ksoapAddResponse>
</s:Body>
</s:Envelope>

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图片.

谢谢！

解决方法:

我终于开始工作了！

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对象映射到在服务中定义testadd类的datacontract.通过明确定义WCF服务中的servicecontract和datacontract的名称空间,这会更改/重新排列wsdl并使datacontract可访问.

我按照本教程摆脱了tempuri.org名称空间 –
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")> _

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

这样做后,我得到了我想要的结果！

这是肥皂要求：

<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>

肥皂反应：

<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>

所以我建议其他人使用ksoap2学习SOAP服务,不要使用默认命名空间,设置自己的命名空间.我浪费了一周时间试图解决这个问题.

希望有一天能帮到某人！
