为什么添加商品后 Paypal Checkout 返回错误？

Question

我正在尝试使用 Javascript SDK 创建 PayPal 订单。如果 PayPal 不返回非描述性 400 错误，我就无法添加商品。

这个标记效果很好：

return actions.order.create({
  purchase_units: [{
    description: "Stuff",
    amount: {
      value: '57.49',
      currency_code: "CAD",
    },
  }],
  application_context: {
    brand_name: "MyBusiness",
    shipping_preference: 'NO_SHIPPING'
  }
});

此标记，我添加了金额细目，而项目则没有：

return actions.order.create({
  purchase_units: [{
    description: "Stuff",
    amount: {
      value: '57.49',
      currency_code: "CAD",
      breakdown: {
        item_total: '57.49',
      }
    },
    items: [{
      unit_amount: '57.49',
      quantity: '1',
      name: "item 1",
    }],
  }],
  application_context: {
    brand_name: "MyBusiness",
    shipping_preference: 'NO_SHIPPING'
  }
});

我正在关注此文档：

https://developer.paypal.com/docs/api/orders/v2/#definition-purchase_unit_request

https://developer.paypal.com/docs/api/orders/v2/#definition-item

我猜我添加故障的方式不起作用。但规范暗示它是数量 -> 细分。

2024 编辑：actions.order.create 已弃用，v2/checkout/orders create 的有效负载只能从服务器发送。请参阅标准集成指南：https://developer.paypal.com/docs/checkout/standard/integrate/

application_context 也已弃用，请使用

payment_source.paypal.experience_context

代替（请参阅 API 参考）
