有一个过滤器叫做login_redirect.

add_filter( \'login_redirect\', \'wpse377295_login_redirect\', 10, 3 );
function wpse377295_login_redirect( $url, $request, $user ) {
    if ( is_wp_error( $user ) ) {
        // It\'s possible that the $user param is a WP_Error. If so, bail out.
        return $url;
    }
    if ( ! user_can( $user, \'update_core\' ) {
        // Only admin users can update core, normally.
        $url = site_url( \'/\' );
    }
    return $url;
}
