你要做的是authenticate 钩子，检查用户是否有pending 角色，如果是，则抛出错误。

//* Add filter to the authenticate hook
add_filter( \'authenticate\', \'wpse_263762_authenticate\', 20, 3 );
function wpse_263762_authenticate( $user, $username, $password ) {
  //* Check if the user has the pending role
  if( ! is_wp_error( $user ) && in_array( \'pending\', $user->roles ) ) {
    //* Throw an error
    $error = new WP_Error();
    $errorMessage = __( \'Your error message goes here.\' );
    $error->add( 401, $errorMessage );
    return $error;
  }
  //* Or return the user
  return $user;
}
