在我的应用程序中,我想使用ksoap
将双值
传递给网络服务
,但我得到了NPE
。在代码中“exit_distance”是 double 值。任何人都可以找到其中的错误并发送示例示例
在此处编写代码
//valus required for test
RB_Constant.RB_Webservice_URL = ?
RB_Constant.RB_Webservice_Namespace = ?
public String getExitsRestaurants() throws SoapFault
{
String data = "";
String serviceUrl = RB_Constant.RB_Webservice_URL;
String serviceNamespace = RB_Constant.RB_Webservice_Namespace;
String soapAction = "http://www.roadbrake.com/GetExitDetailsExtn";
String type_of_soap = "GetExitDetailsExtn";
try
{
SoapObject Request = new SoapObject(serviceNamespace, type_of_soap);
PropertyInfo HighwayIdObj = new PropertyInfo ();
HighwayIdObj.name = "HighwayId";
HighwayIdObj.type = PropertyInfo.INTEGER_CLASS;
Request.addProperty("ExitNo", 7);
Request.addProperty(HighwayIdObj, highwayid);
Request.addProperty("HighwayName", 95);
Request.addProperty("exit_distance", 1.2);
System.out.println("Request Value->"+Request.toString());
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
MarshalDouble md = new MarshalDouble();
md.register(envelope);
envelope.setOutputSoapObject(Request);
try
{
HttpTransportSE androidHttpTransport = new HttpTransportSE(serviceUrl);
androidHttpTransport.call(soapAction, envelope);
}
catch(Exception e)
{
System.out.println("Webservice calling error ->"+e.toString());
}
SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
data = response.toString();
System.out.println("web service response->"+response.toString());
}
catch(Exception e)
{
System.out.println("Soap Method Error ->"+e.toString());
}
return data;
}
public class MarshalDouble implements Marshal
{
@Override
public Object readInstance(XmlPullParser parser, String namespace, String name,
PropertyInfo expected) throws IOException, XmlPullParserException {
return Double.parseDouble(parser.nextText());
}
public void register(SoapSerializationEnvelope cm) {
cm.addMapping(cm.xsd, exit_distance, Double.class, this);
}
@Override
public void writeInstance(XmlSerializer writer, Object obj) throws IOException {
writer.text(obj.toString());
}
}
最佳答案
确切地说,像这样使用它
编码(marshal)级
import org.ksoap2.serialization.Marshal;
import org.ksoap2.serialization.PropertyInfo;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.xmlpull.v1.XmlPullParser;
import org.xmlpull.v1.XmlPullParserException;
import org.xmlpull.v1.XmlSerializer;
import java.io.IOException;
public class MarshalDouble implements Marshal {
public Object readInstance(XmlPullParser parser, String namespace, String name,
PropertyInfo expected) throws IOException, XmlPullParserException {
return Double.parseDouble(parser.nextText());
}
public void register(SoapSerializationEnvelope cm) {
cm.addMapping(cm.xsd, "double", Double.class, this);
}
public void writeInstance(XmlSerializer writer, Object obj) throws IOException {
writer.text(obj.toString());
}
}
实现
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.implicitTypes = true;
envelope.dotNet = true;
envelope.encodingStyle = SoapSerializationEnvelope.XSD;
envelope.setOutputSoapObject(request);
**MarshalDouble md = new MarshalDouble();
md.register(envelope);**
