android访问webservice

   // nameSpace 命名空间，methodName：方法名字；maps：参数集合；webserviceUrl：访问的webservice的网址；比如：http://17.18.199.100:80805/doReqToWebWs.asmx

    private String ws(String nameSpace,String methodName,HashMap<String,String> maps,String webserviceUrl){
        String result="";
        try{
            SoapObject request=new SoapObject(nameSpace,methodName);//NameSpace

            //webService方法中的参数，这个根据你的webservice来，可以没有。
            //但请注意，参数名称和参数类型客户端和服务端一定要一致，否则将可能获取不到你想要的
            Iterator<String> it = maps.keySet().iterator();
            while (it.hasNext()) {
                String keyString = it.next();
                request.addProperty(keyString, maps.get(keyString));
            }

            SoapSerializationEnvelope envelope=new SoapSerializationEnvelope(
                    SoapEnvelope.VER11);

            envelope.dotNet=true;

            envelope.setOutputSoapObject(request);

            HttpTransportSE ht=new HttpTransportSE(webserviceUrl);

            ht.call(nameSpace + methodName, envelope);

            if(envelope.getResponse()!=null){
                SoapPrimitive response=(SoapPrimitive)envelope.getResponse();
                result=response.toString();//这里获得了webService的返回值
                Log.e("resultCode",result);
            }

        }catch(Exception e){
            result=e.getMessage();
            Log.e("resultCode22",result);
        }
        return result;
    }
