Enabling a Listener for HTTP(s) Support with Basic Auth Challenge

When a client attempts to connect to a host (like a relay server), this connection is authenticated with a basic authentication challenge.To setup a HTTP basic authentication, the application registers a listener with the OData SDK. If the IODPHTTPAuthChallengeListener is not registered, an HTTP_AUTH_FAILURE error is returned when a challenge is received.

Syntax

public static void setODPHTTPAuthChallengeListener(ODPClientListeners.IODPHTTPAuthChallengeListener listener) throws ODPException;

Parameters

listener – Listener object that implements the ODPClientListeners.IODPHTTPAuthChallengeListener.The object invokes the callback method of this interface when a connection receives the HTTP_AUTH_FAILURE (HTTP response code 401) challenge

Examples

Register a listener for HTTP(s) Auth Challenge –

ODPUserManager.enableHTTPS(true);
ODPUserManager.setODPHTTPAuthChallengeListener(this);

Implementation of the Listener –

public class UserRegistration implements IODPHTTPAuthChallengeListener
{
      .
      .
     public void startUserRegistration(){
         ODPUserManager.initialize(appID);
         ODPUserManager.setConnectionProfile(serverIP,serverPort,farmID);
         ODPUserManager.enableHTTPS(true);
         ODPUserManager.setODPHTTPAuthChallengeListener(this);
         ODPUserManager.registerUser(username,activationCode,false);

}

// callback method for HTTP authentication 401 challenge 
public ODPHTTPAuthChallengeCredentials getCredentials(String sHostName,String oldUserName, String realm) {
// query the user for credentials, username and password for sHostName
		.
		.
		.
// return the credentials in ODPHTTPAuthChallengeCredentials structure.

			.
return new ODPHTTPAuthChallengeCredentials(username,password);


			
		}
