php - PayPal API 无法连接

Question

这是我的情况，我正在尝试将我的 PayPal API 详细信息插入到为我开发的应用程序中。 PayPal API 详细信息作为占位符提供，并且运行良好。然而，当我插入我的电源时，它每次都会失败。我意识到这是非常模糊的，您可能无法帮助我进行如此概括，但是任何提示都会有所帮助!代码如下。此外，如果您知道我可以获得有关正在发生的事情(错误代码等)的更多详细信息的方法，这也会有所帮助，这样我也可以进行更多研究。

最后，我之前想到的解决方案是，我需要升级账户，但是我只需要知道我是否需要添加信用卡或银行。

您可能混淆了实时凭证和沙盒凭证。代码片段默认采用实时模式。
