如何使用带有角度的laravel将产品添加到购物车

Question

请我需要关于 angular 9 的 laravel 帮助，我试图将产品从前端添加到购物车到后端，这是使用 api 路由的 laravel。当我点击添加到购物车按钮时，没有任何东西添加到购物车，下面是我的代码：

<?php

namespace App\Http\Controllers;

use Illuminate\Support\Facades\Session;

use Illuminate\Http\Request;

use App\Product;

use App\Cart;

class ProductController extends Controller
{

    public function addToCart(Request $request, $id){
         $product = Product::find($id);

         $cart = session()->get('cart');
        // if cart is empty then this the first product
        if(!$cart) {

            $cart = [
                    $id => [
                        "name" => $product->name,
                        "quantity" => 1,
                        "price" => $product->price,
                        "photo" => $product->image
                    ]
            ];

            session()->put('cart', $cart);

            return response()->json(['success'=> 'Product has been added to cart']);
        }

         // if cart not empty then check if this product exist then increment quantity
         if(isset($cart[$id])) {

            $cart[$id]['quantity']++;

            session()->put('cart', $cart);

            return response()->json(['success'=> 'Product has been added to cart']);

        }

        // if item not exist in cart then add to cart with quantity = 1
        $cart[$id] = [
            "name" => $product->name,
            "quantity" => 1,
            "price" => $product->price,
            "photo" => $product->image
        ];

        session()->put('cart', $cart);

        return response()->json(['success'=> 'Product has been added to cart']);
    }
}

请帮忙。
