如何使用Laravel 8验证哈希码是否存在于MySQL表中

php artisan make:model YourModel

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class YourModel extends Model
{
    protected $table = 'your_table';

    protected $fillable = [
        'hash_code',
    ];
}

namespace App\Http\Controllers;

use App\Models\YourModel;
use Illuminate\Http\Request;

class YourController extends Controller
{
    public function validateHashCode(Request $request)
    {
        $hash = $request->input('hash_code');

        $existingRecord = YourModel::where('hash_code', $hash)->first();

        if ($existingRecord) {
            // 哈希码存在于MySQL表中
            // 可以在这里执行相应的逻辑操作
            return '存在';
        } else {
            // 哈希码不存在于MySQL表中
            return '不存在';
        }
    }
}

use App\Http\Controllers\YourController;

Route::post('/validate-hash', [YourController::class, 'validateHashCode']);
