Zookeeper::addAuth — Specify application credentials

说锟斤拷

public Zookeeper::addAuth ( string $scheme , string $cert [, callable $completion_cb = NULL ] ) : bool

The application calls this function to specify its credentials for purposes of authentication. The server will use the security provider specified by the scheme parameter to authenticate the client connection. If the authentication request has failed: - the server connection is dropped. - the watcher is called with the ZOO_AUTH_FAILED_STATE value as the state parameter.
