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();
}
谁能帮帮我?我已经尝试使用 C#.net 项目调用它并且运行良好.很抱歉把所有的 XML 和代码放在这里，但我很绝望......
Can anyone help me? I already tried invoking it using a C#.net project and works perfectly. Sorry to put all the XML and code here but I'm desperate...
推荐答案
我对 android 开发了解不多，但 localhost 是到你的 android 设备的回送地址.您需要将 localhost 替换为运行您的网络服务的服务器的名称或 IP 地址.
i dont know much about android development but localhost is a loopback adress to your android device. you need to replace localhost with the name or ip-address of the server that is running your webservice.
