我有一个联系人表单，正在尝试使用这些值向自己发送电子邮件。服务器正在接收req.body，它出现在控制台中，但是，我的nodemailer文件无法使用数据。我得到一个状态代码"需要至少指定一个'text'或'html'参数…"mail.js和server.js都在根目录中，我使用jQuery将数据传递给server.js，然后module.exports将mail.js导出到server.js。但在交换的某个地方，客户端数据没有进入我在mail.js中创建的对象，即使它只在server.js中被调用。
以下是我的mail.js中减去敏感信息后的内容：
const nodemailer = require("nodemailer");
const mailGun = require("nodemailer-mailgun-transport");
const auth = {
auth: {
api_key: "...",
domain: "..."
}
};
const transporter = nodemailer.createTransport(mailGun(auth));
const sendMail = (name, subject, email, phone, message, cb) => {
const mailOptions = {
from: email,
to: "...", // TODO: the receiver email has to be authorized for the free
tier
name,
phone,
subject,
message
};
transporter.sendMail(mailOptions, function (err, data) {
if (err) {
cb(err, null);
console.log("error occurs");
console.log(err)
} else {
cb(null, data);
console.log("Message sent");
}
});
};
newFunction();
function newFunction() {
module.exports = sendMail;
}
这是我的HTML和server.js:
// Chunk 1
const express = require('express');
const path = require('path');
const sendMail = require('./mail');
const log = console.log;
const app = express();
const PORT = 8080;
// Data parsing
app.use(express.urlencoded({
extended: false
}));
app.use(express.json());
//STATIC FOLDER
app.use("/public", express.static(path.join(__dirname, "public")));
// Render home page
app.get('/', (req, res) => {
res.sendFile(path.join(__dirname, 'views', 'index.html'));
});
// field data
app.post('/email', (req, res) => {
const {
name,
subject,
email,
phone,
message
} = req.body;
log('Data: ', req.body);
sendMail(name, subject, email, phone, message, function(err, data) {
if (err) {
res.status(500).json({
message: 'Internal Error'
})
} else {
res.json({
message: "Email sent!!!!"
})
}
});
});
// Error page
app.get('/error', (req, res) => {
res.sendFile(path.join(__dirname, 'views', 'error.html'));
});
// Email sent page
app.get('/email/sent', (req, res) => {
res.sendFile(path.join(__dirname, 'views', 'emailMessage.html'));
});
// Start server
app.listen(PORT, () => log(`Server is starting on PORT, ${PORT}`));

根据错误消息(期望字段text或html存在(和常规nodemailer文档(不包括message字段(，您似乎只需要在mailOptions对象中将message字段重命名为text。所以你会有：
const mailOptions = {
from: email,
to: "...", // TODO: the receiver email has to be authorized for the free
tier
name,
phone,
subject,
text: message // <-- Simple change!
};
