I am trying to do an HTTP POST of some data. The following is a test
routine that I wrote to try and accomplish this:
void Put()
{
HttpURLConnection connection = null;
DataOutputStream outputStream = null;
String urlServer =
"http://localhost:3571/mycmd.aspx?command=test";;
String message = "This is a message";
try
{
URL url = new URL(urlServer);
connection = (HttpURLConnection) url.openConnection();
// Allow Inputs & Outputs
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setUseCaches(false);
// Enable POST method
connection.setRequestMethod("POST");
connection.setRequestProperty("Connection",
"Keep-Alive");
connection.setRequestProperty("Content-Type",
"application/octet-
stream");
outputStream = new
DataOutputStream( connection.getOutputStream() );
outputStream.writeBytes(message);
// Responses from the server (code and message)
int serverResponseCode = connection.getResponseCode();
String serverResponseMessage =
connection.getResponseMessage();
outputStream.flush();
outputStream.close();
}
catch (Exception ex)
{
int i = 0;
//Exception handling
}
}
If I set urlServer to 'localhost' I get an exception:
java.net.ConnectException: localhost/127.0.0.1:3571 - Connection
refused
I am presuming that this is because the localhost is not being
resolved properly to my host machine (I am running under the
emulator). Is there a way to access a localhost server on my host
machine from the emulator, or do I need a real IP address?
Thanks
