使用 ksoap2 将对象从 android 传递给 wcf soap 服务；它发送和接收 0 [英] passing objects to wcf soap service from android using ksoap2; it sends and receives 0
问题描述
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，它运行良好.但是当我尝试传递对象时，wcf 方法接收到所有对象值的 0.
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.
我在 WP7 应用程序中使用了相同的 SOAP 服务，并且运行良好.
I have used the same SOAP service with a WP7 app and it runs fine.
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 接受一个类 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).
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).
我认为它与命名空间有关，但我不知道如何解决它.我一直在反复试验以使肥皂请求正确，但还没有运气.
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.
谁能帮我弄清楚该怎么做?我尝试了许多选项，它们以某种方式帮助了其他有类似问题的人，但无济于事.
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.

这是我使用 ksoap2 的 java 代码:
this is my java code using ksoap2:

private static final String SOAP_ACTION4 = "http://tempuri.org/IService1/ksoapAdd";

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

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体情况.
I know this is a lot of code, but it think its necessary to understand the whole picture.
谢谢！
推荐答案
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).
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，对于默认命名空间，请求信封无法将传递的 testadd 对象映射到服务中定义了 testadd 类的数据契约.通过为 WCF 服务中的 servicecontract 和 datacontract 显式定义命名空间，这会更改/重新排列 wsdl 并使数据契约可访问.
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
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
我在服务代码(VB)的适当位置添加了以下内容
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.
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!
这是肥皂请求:

<number_2>25</number_2>

</v:Body>
</v:Envelope>
肥皂反应:
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">

<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，设置你自己的命名空间.我浪费了一个星期试图弄清楚这一点.
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.
希望有一天这对某人有所帮助！！
Hope this helps someone someday!!
