本文介绍了使用kso​​ap2 Android的传递对象到WCF SOAP服务;它发送和接收0的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我想使用kso​​ap2访问方法在WCF SOAP服务的机器人。 我能够顺利通过简单类型参数的方法，它工作得很好。 但是，当我试图通过对象，WCF的方法是接受0的所有对象的值。

I am trying to use ksoap2 to access methods in a wcf soap service from android. I was able to successfully pass simple type parameters to the method, it worked fine. But when I try to pass objects, the wcf method is receiving 0 for all the object values.

我已经使用了相同的SOAP服务与WP7的应用程序，它运行良好。

I have used the same SOAP service with a WP7 app and it runs fine.

我有2个方法，我的服务，ksoapadd和addParam。 addParam接受两个整数并返回它们的总和（这部作品）。 ksoapadd需要在课堂上testadd的一个对象，它有两个整型元素ksoapadd返回它们的总和（这获取并发送0）。

I have 2 methods in my service, ksoapadd and addParam. addParam takes in two integer and returns their sum(this works). ksoapadd takes in an object of class testadd which has two integer elements and ksoapadd returns their sum(this gets and sends 0).

我认为这是与命名​​空间，但我不知道如何解决它。我一直在做试验和错误，以获得SOAP请求权，但没有运气。

I think it has something to do with the namespace but I can't figure out how to resolve it. I have been doing trial and error to get the soap request right, but no luck yet.

谁能帮我找出该怎么办？我已经尝试了许多的选择这在某种程度上帮助了其他人有类似的问题，但都无济于事。

Can anyone help me figure out what to do? I have tried many options which somehow helped other people with similar problem but with no avail.

这是我的SOAP请求：

here is my soap request:

<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/">

SOAP响应：

soap response:

<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>

这是使用kso​​ap2我的Java code：

this is my java code using ksoap2:

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：

this is my java class 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code：

service code:

<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

我知道这是一个很大的code，但它认为它有必要了解其全貌。

I know this is a lot of code, but it think its necessary to understand the whole picture.

感谢您！

推荐答案

我终于得到它的工作！

原来我的Andr​​oid ksoap2 code不喜欢默认的命名空间（tempuri.org）通过WCF在SOAP服务中设置。

Turns out my android ksoap2 code didn't like the default namespace(tempuri.org) set by WCF in the SOAP service.

我的猜测是，使用默认命名空间，请求信封无法映射传递testadd对象，其中testadd类是在服务中定义的datacontract。通过在WCF服务明确定义命名空间的的ServiceContract和datacontract，这改变/重排的WSDL，使datacontract访问。

My guess is that with the default namespace, the request envelop was unable to map the passed testadd object to the datacontract in which the testadd class is defined in the service. By defining a namespace explicitly to the servicecontract and datacontract in the WCF service, this changes/rearranges the wsdl and makes the datacontract accessible.

我跟着这个教程摆脱tempuri.org namespace-的 <一href="http://blogs.msdn.com/b/endpoint/archive/2011/05/12/how-to-eliminate-tempuri-org-from-your-service-wsdl.aspx">http://blogs.msdn.com/b/endpoint/archive/2011/05/12/how-to-eliminate-tempuri-org-from-your-service-wsdl.aspx

I followed this tutorial to get rid of the tempuri.org namespace- http://blogs.msdn.com/b/endpoint/archive/2011/05/12/how-to-eliminate-tempuri-org-from-your-service-wsdl.aspx

我添加在服务code（VB）的相应位置以下

I added the following in the appropriate places in the service code (VB)

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

我改变了我的名字空间http://wcfservicetest.org/Service1和编辑命名空间和SOAP_ACTION在Android的Java code与新的命名空间。

I changed my namespace to "http://wcfservicetest.org/Service1" and edited NAMESPACE and SOAP_ACTION in the android java code with the new namespace.

这样做后，我得到了我想要的结果！

After doing this I got the result I wanted!

下面是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响应：

soap response:

<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>

所以我的建议给其他人学习的SOAP服务，ksoap2，做没有用默认的命名空间，设置自己的命名空间。我一个星期浪费试图找出了这一点。

So my advice to anyone else learning SOAP services with ksoap2, do no use the default namespace, set your own namespace. I wasted a week trying to figure this out.

希望这可以帮助别人一天！

Hope this helps someone someday!!
