使用 EJS 模板时 Nodemailer 发送空白电子邮件

当启动页面上的提交按钮被点击时，我的服务器中的以下代码成功发送电子邮件。我正在提取来自 mongoDB 用户输入的列表。当我对变量数据调用 console.log 时，它显示一切都在正确的位置。这是我在终端中得到的内容，后面是代码本身。问题是，除了电子邮件正文为空白之外，一切看起来都正确。主题在那里，但控制台通过 ejs 以 html 形式打印的所有内容都消失了。终端说它在那里，但当我收到电子邮件时，空白......

The following code in my server successfully sends an email when a submit button is hit on the splash page. I am pulling a list that is input from the user coming from mongoDB. When I call console.log on the variable data it shows that everything is in it's right place. This is what I get in the terminal, followed by the code itself. The problem is that everything looks correct except the emails are blank in the body. Subject is there but everything that the console is printing out in html through ejs is gone. Terminal says its there but when I receive email, blank...

所以我第一次回答了我自己的问题。在我的代码中，当我初始化传输程序时，我将安全握手连接设置为“true”。我做了一些阅读，发现那里发生的事情与握手不匹配。在没有详细说明的情况下，我将其更改为“假”，而不是“真”，并且该应用程序第一次完美运行。

So I answered my own question for the first time. In my code, when I initialize the transporter, I have the handshake connection on secure set to 'true'. I did some reading and found that there is something going on there not matching the handshake. Without going into a ton of detail, I changed it to 'false', instead of 'true' and for the first time, the app works perfectly.
