【问题描述】：
我在 Codeigniter 4 中集成了 PayPal，但在更新数据库的事务后我无法获取数据
我想做的是从 IPN 侦听器获得 PayPal 响应，以便我可以相应地修改我的数据库，但无论我做什么，它都不起作用。我已经在我的 PayPal Sandbox 帐户中完成了以下操作：
- 启用自动返回
- 设置自动返回 URL（“仪表板”）
- 启用支付数据传输 (PDT)
- 启用 IPN 消息接收
- 设置 IPN URL ('http:myDomain/Controller/index') 重定向到自动返回 URL 也无法正常工作，交易完成后，用户在单击返回按钮之前无法返回商店。
在此处输入代码
我无法获取数据库中的数据，我正在发送数据
