I wrote the below code

    def decorator(f):
        @functools.wraps(f)
        def wrapped(*args, **kwargs):
            try:
                return f(*args, **kwargs)
            except Exception as exc:
                if isinstance(exc, webob.exc.WSGIHTTPException):
                    if isinstance(errors, int):
                        t_errors = (errors,)
                    else:
                        t_errors = errors
                    if (exc.code in t_errors):
                        raise
                elif isinstance(exc, exception.Forbidden):
                    raise
                elif isinstance(exc, exception.ValidationError):
                    raise
                elif isinstance(exc, exception.Unauthorized):
                    raise
                LOG.exception('Unexpected    exception    in    API    method')
                msg = (_('Unexpected    API    Error.    Please    report    this    at    http://bugs.launchpad.net/nova/    and    attach    the    Nova    API    log    if    possible.\n%s') % type(exc))
                raise webob.exc.HTTPInternalServerError(explanation=msg)
        return wrapped
    return decorator
