use Abdursoft\LaravelBkash\Bkash;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Session;
use Illuminate\Support\Facades\Validator;

class BkashController extends Controller
{

    protected $bkash;
    public function __construct()
    {

        $this->bkash = new Bkash(env('BKASH_USERNAME'),env('BKASH_PASSWORD'),env('BKASH_APP_KEY'),env('BKASH_APP_SECRET'),'sandbox',"http://127.0.0.1:8000/bkash/callback"); //use sandbox for sandbox testing and production for production service
    }

    /**
     * Create payment
     */
    public function createPayment(Request $request){
        $validator = Validator::make($request->all(),[
            'amount' => 'required',
            'reference' => 'required',
        ]);

        if($validator->fails()){
            return response()->json($validator->errors());
        }

        $payment = $this->bkash->paymentCreate($request->reference,$request->amount,uniqid());
        return redirect()->away($payment['bkashURL']);
    }

    /**
     * Refund payment
     */
    public function refundPayment(Request $request){
        $refund = $this->bkash->refund($request->id,$request->txn,$request->amount,$request->sku,$request->reason);
        if($refund['statusCode'] === '0000'){
            return redirect('/')->with('success',"Refund process has been completed");
        }else{
            return redirect('/')->with('error',"Refund process has been faild");
        }
    }

    /**
     * Bkash callback
     */
    public function callbackResponse(Request $request){
        if($request->query('status') == 'success'){
            $execute = $this->bkash->paymentExecute($request->query('paymentID'));
            Session::put(['paymentExecution' => $execute]);
            if($execute['statusCode'] == '0000'){
                return redirect('/')->with('success','Payment has been completed');
            }elseif($execute['statusCode'] == '2062'){
                return redirect('/')->with('success','Payment has already been compeled');
            }
        }elseif($request->query('status') == 'cancel'){
            return redirect('/')->with('error','Payment has been canceled');
        }elseif($request->query('status') == 'failure'){
            return redirect('/')->with('error','Payment has been faild');
        }else{
            return redirect('/')->with('error','Payment couldn\'t completed');
        }
    }
}

Route::prefix('bkash')->group(function(){
    Route::post('payment', [BkashController::class, 'createPayment']);
    Route::post('refund', [BkashController::class, 'refundPayment']);
    Route::get('cancel', [BkashController::class, 'callbackResponse']);
    Route::get('callback', [BkashController::class, 'callbackResponse']);
});
