Laravel:如果日期存在，我如何验证该日期？

namespace App\Rules;

use Carbon\Carbon;
use Illuminate\Contracts\Validation\Rule;

class DateExistsRule implements Rule
{
    public function passes($attribute, $value)
    {
        try {
            Carbon::parse($value);
            return true;
        } catch (\Exception $e) {
            return false;
        }
    }

    public function message()
    {
        return 'The date does not exist.';
    }
}

use App\Rules\DateExistsRule;
use Illuminate\Support\Facades\Validator;

$validator = Validator::make($data, [
    'date' => ['required', 'date', new DateExistsRule],
]);

if ($validator->fails()) {
    // 验证失败的处理逻辑
} else {
    // 验证成功的处理逻辑
}
