paypal - 尝试将 PayPal REST Orders API 用于 PayPal Market Places 时出现 curl 问题

Question

我正在尝试遵循本文档中所示的订单集成指南:https://developer.paypal.com/docs/marketplaces/orders/integration-guide/

我能够完成获取访问 token 以及“创建订单”部分的所有内容。但是，当我尝试在我的本地主机中调用 Create Order 时，我得到以下输出:

注意: undefined variable :数据在C:\xampp\htdocs\ordersAPI.php第75行注意: undefined variable :数据在C:\xampp\htdocs\ordersAPI.php第85行

我一直在绞尽脑汁想弄清楚为什么会这样。我一直在查看各种堆栈问题，但我无法弄清楚我遗漏了什么。似乎我确实定义了“数据”变量，所以我不确定哪里出错了，也不确定为什么返回 1。

尝试在我发现的另一个测试站点上测试我的凭据时，我也收到返回 500 的错误。所以我不确定是账户有问题，还是我的代码有问题。我不认为这是一个帐户问题，因为它给出了有关 undefined variable 的错误。

Answer 1

$data 变量未作为参数传递到第 71 行的市场函数中，也未作为参数传递到第 96 行的函数调用中。这就是导致错误的原因。

此外，虽然“创建订单”调用会起作用，但如果您尝试下一步调用“支付订单”，则会生成错误 500，因为您正在尝试使用 PayPal 的 MarketPlaces API，并且尚未批准用于 MarketPlaces API。
