仅在确认付款后，如何在 NodeMailer 中发送电子邮件？答案

【问题标题】：How do I send email in NodeMailer only when payment is confirmed?仅在确认付款后，如何在 NodeMailer 中发送电子邮件？

【问题描述】：

当我确认付款并验证付款时，NodeMailer 必须将电子邮件发送到从req.body.email 获得的特定电子邮件 ID。但是我收到了这个错误，并且没有发送电子邮件就完成了付款。

Razorpay 用于支付处理。

接下来我可以尝试什么？

【问题讨论】：

看起来req.body.email 未定义。这与 razorpay 无关。
你能告诉我现在应该做什么，因为我是初学者，你的帮助对我来说会很棒。
找出req.body.email 未定义的原因
请提供足够的代码，以便其他人更好地理解或重现问题。

【解决方案1】：

在您链接的屏幕截图中，我看不到任何电子邮件字段正在传递

这会导致您的电子邮件字段未定义，从而导致 node-mailer 抛出错误。您必须在发布电子邮件时传递带有数据的对象，这是官方网站上的示例 - https://axios-http.com/docs/post_example
