Can'；t将ComplexType对象从ksoap2 for android发送到soap Web服务

我正在做一个移动应用程序，通过使用ksoap2使用web服务

到目前为止，我能够通过包含字符串、double、int等的Web服务发送复杂对象

然后我就可以通过网络发送字节数组了。现在我的问题来了：

当我试图创建一个对象通过网络发送时，当其中一个参数是字节数组时，我从服务器获得一个faultstring

我正在访问的web服务具有以下wsdl文件：

我用于访问web服务的值如下：

String NAMESPACE = "http://sensors.components/xsd";
        try {
            SoapObject request = new SoapObject(connection.getNAMESPACE(), connection.getMETHOD_NAME());

            PropertyInfo object = new PropertyInfo();
            object.setName("picture");
            object.setValue(picture);
            object.setType(picture.getClass());
            object.setNamespace(NAMESPACE);
            request.addProperty(object);

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

            MarshalDouble md = new MarshalDouble();
            md.register(envelope);
            new MarshalBase64().register(envelope);


            envelope.addMapping(NAMESPACE, "Pic", new Pic().getClass());

            HttpTransportSE androidHttpTransport = new HttpTransportSE(
                    connection.getURL());

            androidHttpTransport.call(connection.getSOAP_ACTION(), envelope);

            SoapPrimitive response = (SoapPrimitive) envelope.getResponse();
            System.out.println("response: " + response.toString());
        } catch (Exception e) {
            e.printStackTrace();
        }

namespace=“” url=“” soap action=“” 方法名称=“pictureWebservice”

然后，我将使用以下代码将其发送到Web服务：

String NAMESPACE = "http://sensors.components/xsd";
        try {
            SoapObject request = new SoapObject(connection.getNAMESPACE(), connection.getMETHOD_NAME());

            PropertyInfo object = new PropertyInfo();
            object.setName("picture");
            object.setValue(picture);
            object.setType(picture.getClass());
            object.setNamespace(NAMESPACE);
            request.addProperty(object);

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

            MarshalDouble md = new MarshalDouble();
            md.register(envelope);
            new MarshalBase64().register(envelope);


            envelope.addMapping(NAMESPACE, "Pic", new Pic().getClass());

            HttpTransportSE androidHttpTransport = new HttpTransportSE(
                    connection.getURL());

            androidHttpTransport.call(connection.getSOAP_ACTION(), envelope);

            SoapPrimitive response = (SoapPrimitive) envelope.getResponse();
            System.out.println("response: " + response.toString());
        } catch (Exception e) {
            e.printStackTrace();
        }

尽管我曾经尝试并成功地通过double传递对象，并注册它们，并且能够传递byte[]，但我无法传递一个复杂类型，其中包含byte[]作为参数

logcat错误如下所示：

有人有什么想法、解决方案或建议吗？事先非常感谢

编辑：

从我所能看出的问题是，在服务器的Web服务中，我调用类Pic中的imageInByte参数为null。没有其他参数为null。名称、纬度、经度、精度和时间都是有效参数，byt imageInByte为空。为什么？请帮助

在您的wsdl中，您已经将这个字段“imageInByte”定义为简单类型，这就是为什么它会给您这个错误

将其定义为复杂类型，包含您试图传递的所有字段

谢谢，

发生的情况是，在web服务的服务器中，Pic imageInByte的参数为空。没有其他参数仅为null imageInByte。为什么？有人能帮我吗？目前没有回应。
