从我的 android 应用程序发送位置的函数如下..

private boolean sendLocation(String latitude, String longitude, String UserName)
    {
        boolean flag = false;
        final String SOAP_ACTION = "http://tempuri.org/addLocationData";
        final String METHOD_NAME = "addLocationData";
        SoapObject request = new SoapObject (NAMESPACE, METHOD_NAME);

        request.addProperty("Latitude",latitude);
        request.addProperty("Longitude", longitude);
        request.addProperty("UserName", UserName);
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

        System.out.println(request);
        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

        try
        {
            androidHttpTransport.call(SOAP_ACTION, envelope);
            SoapPrimitive result= (SoapPrimitive)envelope.getResponse();
            String res_string = result.toString();
            System.out.println(res_string);
        }
        catch(SocketException ex)
        {
            Log.e("Error : " , "Error on soapPrimitiveData() " + ex.getMessage());
            ex.printStackTrace();
        }
        catch(Exception e)
        {
            Log.e("Error : " , "Error on soapPrimitiveData() " + e.getMessage());
            e.printStackTrace();
        };
        return flag;
    }

谁能帮我写代码，谁能告诉我哪里错了？

Answer 1

试试这个：

最终字符串 SOAP_ACTION = "http://tempuri.org/addLocationData";

final String METHOD_NAME = "addLocationData";
SoapObject request = new SoapObject (NAMESPACE, METHOD_NAME);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
        SoapEnvelope.VER11);
envelope.dotNet = true;     
envelope.xsd = Constants.NAME_SPACE;
envelope.enc = "http://schemas.datacontract.org/2004/07/Entity";
 request.addProperty("Latitude",latitude);
request.addProperty("Longitude", longitude);
request.addProperty("UserName", UserName);

envelope.setOutputSoapObject(request);
AndroidHttpTransport androidHttpTransport = new AndroidHttpTransport(
        URL, 60000);
androidHttpTransport
        .setXmlVersionTag("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");

try {
    androidHttpTransport.call(NAMESPACE, METHOD_NAME, envelope);
    } 
catch (Exception e)
    {
    e.printStackTrace();
    }

SoapObject result = (SoapObject) envelope.bodyIn;
Log.e("result", "" + result.toString());
