您的代码已经在使用 Checkout-NET-SDK（抽象了 v2/checkout/orders PayPal REST API）来创建和捕获 PayPal 订单。 捕获 API 响应提供成功或失败的即时通知。 特别是purchase_units[0].payments.captures[0].id是 PayPal 交易 ID，以及应该保存在数据库中的内容。 此时还应验证订单总额。
另外，您似乎正在使用旧的基于重定向的流程进行审批。 相反，请遵循PayPal Checkout 集成指南，并通过服务器上的 2 个路由（url 路径）执行创建订单和捕获订单 API 步骤。 这两个路由都应该只返回 JSON 数据（没有 HTML 或文本）。 第二条路线将订单 ID 作为输入参数（路径或正文变量），如前所述，应检查操作结果以验证金额是否正确并存储其生成的付款详细信息，以及执行任何必要的业务逻辑（例如在将返回的 JSON 转发给前端调用者之前立即发送确认电子邮件或预订产品）。 如果发生错误，也转发它的 JSON 详细信息，因为前端必须处理这种情况。
将这 2 条路由与此前端审批流程配对： https ://developer.paypal.com/demo/checkout/#/pattern/server。 （如果您需要从客户端向服务器发送任何其他数据，例如项目数组或选定的选项，请在获取中添加一个body参数，其值为 JSON 字符串或对象）
