Question

我使用以下代码访问webserivce

public SoapObject getWeather() throws Exception
    {
        SoapObject request = new SoapObject("http://www.freewebservicesx.com", "GetCurrentGoldPrice");
        //request.addProperty("PlaceName", city);
        request.addProperty("Username","myusername");
        request.addProperty("Password","pass");
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.setOutputSoapObject(request);
        // It seems that it is a .NET Web service because it doesn't work without next line
        envelope.dotNet = true;

        HttpTransportSE transport = new HttpTransportSE("http://www.freewebservicesx.com/GetGoldPrice.asmx");
        transport.call("http://freewebservicesx.com/GetCurrentGoldPrice", envelope);

        return (SoapObject) envelope.getResponse();
    }


    public List<CharSequence> getWeatherForecast() 
    {
        SoapObject obj = null;
        try {
            obj = getWeather();
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
//error is being thrown here
            Log.e("error",e.getMessage());
        }
        SoapObject details = (SoapObject) obj.getProperty("GetCurrentGoldPriceResult");

        List<CharSequence> list = new ArrayList<CharSequence>(details.getPropertyCount());
        for (int i = 0; i < details.getPropertyCount(); i++) {
            Object property = details.getProperty(i);
            if (property instanceof SoapObject) {
                SoapObject weather = (SoapObject) property;
                String day = weather.getProperty("string").toString();
                String min = weather.getProperty("string").toString();
                //String max = weather.getProperty("MaxTemperatureF").toString();
                Log.v("ts is whait ai am ",day);

                list.add(day + " :: " + min);
            }
        }
        return list;
    }

http://www.freewebservicesx.com/GetGoldPrice.asmx?op=GetCurrentGoldPrice包含服务的详细信息。我的绑定交易失败了。

请更改行：

envelope.dotNet = "true";

到

envelope.dotNet = "false";

因为“true”总是向webserver发送一个空值，所以设置一个false ..

和你的代码中的其他东西

request.addProperty("Username","myusername");

request.addProperty("Password","pass");

检查客户端和服务器端webservice上的参数名称（用户名，密码）必须相同，这意味着它区分大小写。

我希望代码可以帮助你。
