客户端数据未到达服务器端......也许

Question

我有一个联系表，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 并且它出现在控制台中，但是，我的 nodemailer 文件无法使用该数据。我得到一个状态码 "Need at least one of 'text' or 'html' parameters specified..." mail.js 和 server.js 都在根目录中，我将数据传递给 server.js 使用 jQuery 然后 module.exports mail.js 到 server.js 但是在交换的某个地方，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

这是我的 mail.js 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 和我的 server.js:

Answer 1

根据错误消息（期望字段 text 或 html 存在）和一般的 nodemailer 文档（不包括 message 字段），看起来你只需要在 mailOptions 对象中将 message 字段重命名为 text。所以你会：

const mailOptions = {
    from: email, 
    to: "...", // TODO: the receiver email has to be authorized for the free 
         tier
    name,
    phone,
    subject,
    text: message // <-- Simple change!
  };

客户端数据未到达服务器端......也许

Client side data not reaching server side...maybe
