产品控制器：

    */
    public function index()
    {
        $products = Product::all();
        return view('home', ['products'=> $products]);
    }

    public function getAddToCart(Request $request, $id) 
    {
        $product = Product::find($id);
        $oldCart = Session::has('cart') ? Session::get('cart') : null;
        $cart = new Cart($oldCart);
        $cart->add($product, $product->id);
        
        $request->session()->put('cart', $cart);
        return redirect()->route('home');
    }

    public function getCart()
    {
        if (!Session::has('cart')) {
            return view('cart');
        }
        $oldCart = Session::get('cart');

        $cart = new Cart($oldCart); 
        return view('cart', ['products' => $cart->items, 'totalPrice' => $cart->totalPrice]);
    }

    public function destroy(Request $request, $id)
    {
        $oldCart = Session::has('cart') ? Session::get('cart') : null;
        $cart = new Cart($oldCart);
        $cart->delete($product, $product->id);
        $request->session()->put('cart', $cart);
