/**
 * Default implementation of {@link UserTokenHandler}. This class will use

 * if it can be obtained from the given execution context. This helps ensure
 * persistent connections created with a particular user identity within
 * a particular security context can be reused by the same user only.
 * 

* DefaultUserTokenHandler will use the user principal of connection * based authentication schemes such as NTLM or that of the SSL session * with the client authentication turned on. If both are unavailable, * {@code null} token will be returned. * * @since 4.0 */ @Contract(threading = ThreadingBehavior.IMMUTABLE) public class DefaultUserTokenHandler implements UserTokenHandler { public static final DefaultUserTokenHandler INSTANCE = new DefaultUserTokenHandler(); @Override public Object getUserToken(final HttpContext context) { final HttpClientContext clientContext = HttpClientContext.adapt(context); Principal userPrincipal = null; final AuthState targetAuthState = clientContext.getTargetAuthState(); if (targetAuthState != null) { userPrincipal = getAuthPrincipal(targetAuthState); if (userPrincipal == null) { final AuthState proxyAuthState = clientContext.getProxyAuthState(); userPrincipal = getAuthPrincipal(proxyAuthState); } } if (userPrincipal == null) { final HttpConnection conn = clientContext.getConnection(); if (conn.isOpen() && conn instanceof ManagedHttpClientConnection) { final SSLSession sslsession = ((ManagedHttpClientConnection) conn).getSSLSession(); if (sslsession != null) { userPrincipal = sslsession.getLocalPrincipal(); } } } return userPrincipal; } private static Principal getAuthPrincipal(final AuthState authState) { final AuthScheme scheme = authState.getAuthScheme(); if (scheme != null && scheme.isComplete() && scheme.isConnectionBased()) { final Credentials creds = authState.getCredentials(); if (creds != null) { return creds.getUserPrincipal(); } } return null; } }
