Laravel中的互動控制台命令

>在Laravel構建命令行工具時，常見的挑戰之一是優雅地處理丟失或不正確的用戶輸入。 Laravel的提示formissingInput特徵通過將標準工匠命令轉換為交互式對話來解決這一問題。

>當缺失參數時，您的命令可以通過有用的提示使用戶吸引用戶，從而通過所需的輸入引導他們。這種方法對於復雜的維護任務，部署腳本或您需要確保准確的命令行輸入的任何情況而在維護專業且用戶友好的界面時尤其有價值。

>讓我們探索帶有交互式提示的數據庫備份命令的實踐示例：

namespace App\Console\Commands;

use Illuminate\Console\Command;
use Illuminate\Contracts\Console\PromptsForMissingInput;

class BackupDatabase extends Command implements PromptsForMissingInput
{
    protected $signature = &#39;db:backup
        {connection? : Database connection to backup}
        {--tables=* : Specific tables to backup}
        {--compress : Compress the backup file}&#39;;
    protected $description = &#39;Create a database backup&#39;;

    protected function promptForMissingArgumentsUsing(): array
    {
        return [
            &#39;connection&#39; => fn () => choice(
                'Which database connection should be backed up?',
                [
                    'mysql' => 'MySQL Primary Database',
                    'sqlite' => 'SQLite Testing Database',
                    'pgsql' => 'PostgreSQL Analytics Database'
                ],
                'mysql'
            ),
            '--tables' => fn () => multiChoice(
                'Select tables to backup (leave empty for all):',
                $this->getAvailableTables()
            ),
            '--compress' => fn () => confirm(
                'Would you like to compress the backup?',
                true
            )
        ];
    }

    private function getAvailableTables(): array
    {
        // Fetch tables from database
        return ['users', 'posts', 'comments', 'orders'];
    }

    public function handle()
    {
        $connection = $this->argument('connection');
        $tables = $this->option('tables');
        $compress = $this->option('compress');
        $this->info("Starting backup of {$connection} database...");

        // Backup logic here...
    }
}
