我在MacBook Pro的本地主机上，所以没有防火墙，而且还有我的代码：
private String callPHPWebServiceForAuthenticate(String username, String password) {
Log.w(TAG, "callPHPWebServiceForAuthenticate : start-end");
//Settings
String soap_url = "http://localhost/studentCo/bl/ws.php";//url du serveur SOAP
String soap_action = "http://localhost/studentCo/bl/ws.php/wsAuthenticate";//le service interrogé
String method_name = "wsAuthenticate";//La méthode
String target_namespace = "urn:StudentCo";//voir wsdl : targetNameSpace ou tns
//
String wsResponse = null;
SoapObject request = new SoapObject(target_namespace, method_name);
//Params :
PropertyInfo propInfo1 = new PropertyInfo();
propInfo1.setName("username");
propInfo1.setType(PropertyInfo.STRING_CLASS);
propInfo1.setValue(username);
request.addProperty(propInfo1);
//
PropertyInfo propInfo2 = new PropertyInfo();
propInfo2.setName("password");
propInfo2.setType(PropertyInfo.STRING_CLASS);
propInfo2.setValue(password);
request.addProperty(propInfo2);
Log.w(TAG, request.toString());
//Request-call
SoapSerializationEnvelope envelope = new
SoapSerializationEnvelope(SoapEnvelope.VER11);
//envelope.dotNet = true;//si le service est .NET based
envelope.setOutputSoapObject(request);
HttpTransportSE httpTransportSE = new HttpTransportSE(soap_url);
try {
httpTransportSE.call(soap_action, envelope);
Object response = envelope.getResponse();
wsResponse = response.toString();
return wsResponse;
}
catch (IOException e) {
e.printStackTrace();
return null;
}
catch (XmlPullParserException e) {
e.printStackTrace();
return null;
}
catch (Exception e) {
e.printStackTrace();
return null;
}
}
