我正在尝试通过 Stripe 结账会话传递元数据。目前，我正在尝试按照 Stripe 文档中的建议通过 payment_intent_data.metadata 传递它，但我收到 500 错误异常 ： “Stripe\Exception\InvalidRequestException”，消息 ： “无效对象”。但我似乎遵循了 Stripe 文档上的建议配置，所以我陷入了停滞。

StripeController.php

    public function handle_checkout(Request $request)
    {
        $stripe = new \Stripe\StripeClient(env("STRIPE_PRIVATE_KEY"));

        $req_content = json_decode($request->getContent(), true);

        $line_items = []; 

        $email = "";

        foreach($req_content as $key => $val) {
            $new_line_item = [
                'price_data' => [
                'currency' => 'usd',
                'product_data' => [
                    'name' => $val["product_item"]["name"],
                ],
                'unit_amount' => $val["product_item"]["price"] * 100,
                ],
                'quantity' => $val["cart_item"]["quantity"]
            ];
            
            $email = $val["user_email"];

            array_push($line_items, $new_line_item);
        }

        $checkout_session = $stripe->checkout->sessions->create([
            'shipping_address_collection' => ['allowed_countries' => ['US']],
            'payment_method_types' => ['card'],
            "customer_email" => $email,
            'line_items' => $line_items,
            'payment_intent_data' => [ 
                 ## Here, I am just putting "AAA" for testing
                'metadata' => "AAA"
            ],
            'mode' => 'payment',
            'success_url' => 'my success url ...',
            'cancel_url' => 'my cancel url...',
          ]);
     
        return $checkout_session->url; 
    }

如果我不添加

'payment_intent_data' => [ 
                 ## Here, I am just putting "AAA" for testing
                'metadata' => "AAA"
            ], 

然后就可以了。但我想通过结帐流程传递元数据并在 payment_intent.succeeded 上获取它。

想法？
