以下是我一直在使用的技巧：

使用数组存储重写，对数组进行哈希运算，将哈希数组存储为选项，检查存储的选项是否与当前重写哈希匹配；如果不是，请更新“重写”代码段（这是一个起点，而不是成品）：

add_action( \'init\', \'wpse_393260_rewrites\' );
function wpse_393260_rewrites() {
    // Array of rewrites.
    $my_rewrites = array(
        \'foo/([a-z0-9-]+)[/]?$\' => \'index.php?foo=$matches[1]\',
        \'bar/([a-z0-9-]+)[/]?$\' => \'index.php?bar=$matches[1]\',
        // etc.
    );
    // Implements the rewrite rules.
    foreach ( $my_rewrites as $regex => $query ) {
        add_rewrite_rule( $regex, $query, \'top\' );
    }
    // Hashes the $my_rewrites array.
    $hashed_rewrites = md5( serialize( $my_rewrites ) );
    // Gets the currently-active rewrites from the option.
    $my_current_rewrites = get_option( \'my_rewrites_option\' );
    // If anything\'s changed, flush the rewrites and update the option.
    if ( $my_current_rewrites !== $hashed_rewrites ) {
        flush_rewrite_rules();
        update_option( \'my_rewrites_option\', $hashed_rewrites );
    }
}
