kSoap2发送收藏

Question

我有android应用程序，该应用程序将一些数据发送到android应用程序上的.net Web服务（不是wcf，简单的Web服务）。我有类，该类实现了KvmSerializable接口

public class OrderDTO extends BaseSoapObject
{
    public int ID;
    public Date OrderDate;
    public UserDTO Owner; 
    public Vector<OrderItemDTO> Products;

    @Override
public void getPropertyInfo(int index, Hashtable properties, PropertyInfo info)
{
    switch(index)
    {
        case 0:
            info.type = PropertyInfo.INTEGER_CLASS;
            info.name = "ID";
            break;

        case 1:
            info.type = MarshalDate.DATE_CLASS;
            info.name = "OrderDate";
            break;

        case 2:
            info.type = UserDTO.class;
            info.name = "Owner";
            break;

        case 3:
            info.type = PropertyInfo.VECTOR_CLASS;
            info.name = "Products";
            break;

        default:
            break;
    }       
}
}

在服务器端，我上课

public class OrderDTO
{
    public virtual int ID { get; set; }
    public virtual UserDTO Owner { get; set; }
    public virtual DateTime OrderDate { get; set; }
    public virtual OrderItemDTO[] Products { get; set; }

    public OrderDTO()
    {    
    }
}

和网络服务方法

[WebMethod]

public void SaveOrder(OrderDTO order)
{
    try
    {
        // do somthing
    }
    catch (Exception e)
    {

    }
    finally
    {
    }

}

我已经成功从android调用了此方法，字段Owner和OrderDate已正确填写，但是Products字段为空（不为null，只是空的）

我尝试使用Array，ArrayList和Vector-没有变化

当我看到请求转储并看到唯一的不同时（集合项的标签名称：

<Products i:type="c:Array" c:arrayType="d:anyType[1]">
    <item i:type="n0:OrderItemDTO">
       <ID i:type="d:int">0</ID>
       <AssignedCode i:type="d:string">0001</AssignedCode>
       <Count i:type="d:int">5</Count>
    </item>
</Products>

在我的wsdl中：

<Products>
    <OrderItemDTO>
        <ID>int</ID>
        <Count>int</Count>
        <AssignedCode>string</AssignedCode>
    </OrderItemDTO>
    <OrderItemDTO>
        <ID>int</ID>
        <Count>int</Count>
        <AssignedCode>string</AssignedCode>
    </OrderItemDTO>
</Products>

和我与服务交互的android代码：

OrderDTO dto = new OrderDTO(order);
SoapObject request = new SoapObject(Namespace, SaveOrderMethod);

PropertyInfo pi = new PropertyInfo();
pi.setName("order");
pi.setValue(dto);
pi.setType(dto.getClass());
request.addProperty(pi); 

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

envelope.addMapping(Namespace, "OrderItemDTO", new OrderItemDTO().getClass());
envelope.addMapping(Namespace, "UserDTO", new UserDTO().getClass());
envelope.addMapping(Namespace, "OrderDTO", new OrderDTO().getClass());

Marshal dateMarshal = new MarshalDate();
dateMarshal.register(envelope);

HttpTransportSE androidHttpTransport = new HttpTransportSE(Url);
androidHttpTransport.debug = true;

try
{
    androidHttpTransport.call(SaveOrderSoapAction, envelope);
} 
catch (Exception e) 
{
    Log.e(Tag, e.getMessage());
}

Answer 1

我已经找到了答案，我需要向OrderDTO.getPropertyInfo方法添加一些代码PropertyInfo elementInfo = new PropertyInfo（）; elementInfo.name =“ OrderItemDTO”; elementInfo.type = new OrderItemDTO（）。getClass（）; info.elementType = elementInfo;
