如何保存TWAIN扫描数据?

Question

所以我使用TWAIN扫描文档(计费时需要的报价表)，当文档被扫描时，数据应该保存在我的数据库的rubrique_facturations表中。然而，当我按下注册(保存)按钮，什么都没有发生，数据不保存，我不知道问题在哪里(我没有得到任何错误);问题是，我不熟悉Laravel scan和TWAIN，所以在知道扫描的文档是一个表的情况下，如何将扫描的数据插入到我的数据库中?它包含与我的rubrique_facturation表相同的字段。这是我的控制器。

namespace AppHttpControllers;
use AppModelsRubrique_facturation;
use IlluminateHttpRequest;
use IlluminateSupportFacadesDB;
class Rubrique_facturationController extends Controller
{
/**
* Display a listing of the resource.
*
* @return IlluminateHttpResponse
*/
public function index()
{
$rubrique = Rubrique_facturation::all();
return view('facturation.index', ['facturations' => $rubrique]);
}
public function scan(Request $request)
{
// Get the scanned data from the POST request
$scannedData = $request->input('scanned_data');
// Validate the scanned data before storing it
$request->validate([
'scanned_data' => 'required|string|max:255',
]);
// Convert the base64-encoded scanned data to binary
$binaryData = base64_decode($scannedData);
// Store the scanned data in your database
$scan = new Rubrique_facturation;
$scan->scan_data = $binaryData;
$scan->save();
// Redirect the user to a success page or back to the form page
return redirect()->back()->with('success', 'Scanned data has been stored successfully.');
}
public function saveScan(Request $request)
{
// récupération des données scannées
$designation = $_POST['designation'];
$quantite = $_POST['quantite'];
$prix_unitaire  = $_POST['prix_unitaire '];
$MontantHT = $_POST['MontantHT'];
$totaleHT = $_POST['totaleHT'];
$tva = $_POST['tva'];
$TotalTtc = $_POST['TotalTtc'];
$unite_rebrique_financier = $_POST['unite_rebrique_financier'];
// sérialisation des colonnes qui peuvent contenir de 1 jusqu'à n valeurs
$designation = serialize($designation);
$quantite = serialize($quantite);
$prix_unitaire  = serialize($prix_unitaire);
$MontantHT = serialize($MontantHT);
$totaleHT = serialize($totaleHT);
$tva = serialize($tva);
$TotalTtc = serialize($TotalTtc);
$unite_rebrique_financier = serialize($unite_rebrique_financier);
// insertion des données dans la table
DB::table('rubrique_facturation')->insert([
'designation' => $designation,
'quantite' => $quantite,
'prix_unitaire ' => $prix_unitaire,

public function create()
{
//

/**

public function store(Request $request)

这是我对扫描和保存扫描数据的看法

您的post actionsave.php是不正确的。你应该先注册网络路由。例如，在"web.php"中添加如下代码:

Route::post('/barcode_qr_reader/upload', 'AppHttpControllersRubrique_facturationController@saveScan')->name('saveScan');

然后改变动作:

<form action="{{ route('saveScan') }}" method="post" enctype="multipart/form-data">
