.net – 使用Android调用SOAP Webservice时连接被拒绝

我在.net中开发了一个web服务,我试图在Android中调用它.
要调用web服务我正在使用kso​​ap2.

WDSL的URL是:http://localhost/Cidadaos_Cidade/Open.asmx?WSDL

这是WSDL

这是调用它的代码

SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);


        SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        //soapEnvelope.dotNet = true; //tried with and without this flag
        soapEnvelope.setOutputSoapObject(request);

        AndroidHttpTransport aht = new AndroidHttpTransport(URL);
        try{
            //crashes in the following line with the exception:
            //java.net.ConnectException: localhost/127.0.0.1:80 - Connection refused
            aht.call(SOAP_ACTION, soapEnvelope);
            SoapObject resultsRequestSOAP = (SoapObject) soapEnvelope.bodyIn;

        }catch(Exception ex){
            ex.printStackTrace();
        }

谁能帮我?我已经尝试使用C#.net项目调用它并且工作得很好.
很抱歉把所有的XML和代码放在这里,但我很绝望……

我不太了解Android开发,但localhost是你的Android设备的环回地址.您需要将localhost替换为运行Web服务的服务器的名称或IP地址.
