Firebase nodemailer - 快照数据问题

Question

我想收到带有变量“mail”“message”“name”的电子邮件......就像“你好{name}你好吗？你的电子邮件是{mail}，这是你的{message}联系人的副本form" .....问题是我只收到 {mail} 而不是 {message} {name}

const functions = require('firebase-functions');
const admin = require('firebase-admin');
const nodemailer = require('nodemailer');

const gmailEmail = functions.config().gmail.login;
const gmailPassword = functions.config().gmail.pass;

admin.initializeApp();


var goMail = function (message) {


    const transporter = nodemailer.createTransport({
        service: 'gmail',
        auth: {
            user: gmailEmail,
            pass: gmailPassword
        }
    });

    const mailOptions = {
        from: gmailEmail, 
        to: 'la***@gmail.com', 
        subject: 'Hello ✔', 
        text: '!' + message, 
        html: '!' + message 
    };

    const getDeliveryStatus = function (error, info) {
        if (error) {
            return console.log(error);
        }
        console.log('Message sent: %s', info.messageId);

    };

    transporter.sendMail(mailOptions, getDeliveryStatus);
}; 
exports.onDataAdded = functions.database.ref('/emails/{sessionId}').onCreate(function (snap, context) {

    const createdData = snap.val();
    var text = createdData.mail;
        goMail(text);
});

这就是我的 firebase 实时数据库的外观

 emails
     -**sesionID*
        mail: "randommail@gmail.com"
        message:"test"
        name:"testname"

我尝试从代码中添加/编辑它，但这无济于事：-/

   var goMail = function (message, secondmessage)


   const mailOptions = {
        from: gmailEmail, 
        to: 'la***@gmail.com', 
        subject: 'Hello ✔', 
        text: '!' + message +  secondmessage, 
        html: '!' + message +  secondmessage
    };


 var text = createdData.mail;
 var secondtext = createdData.name
 goMail(text, secondtext);

谢谢大家的回答，祝你有美好的一天！

您只收到 {{mail}}，因为该值已在您的云函数上设置为常量值，也在您的代码调用 goMail 函数时，您发送 2 个参数而不是预期的 1 个参数.尝试将您的 goMail 功能更改为（例如）：

var goMail = function (name, message) {


    const transporter = nodemailer.createTransport({
        service: 'gmail',
        auth: {
            user: gmailEmail,
            pass: gmailPassword
        }
    });

    const mailOptions = {
        from: gmailEmail, 
        to: 'la***@gmail.com', 
        subject: 'Hello ✔', 
        text: '!' + name + message, 
        html: '!' + name + message 
    };

    const getDeliveryStatus = function (error, info) {
        if (error) {
            return console.log(error);
        }
        console.log('Message sent: %s', info.messageId);

    };

    transporter.sendMail(mailOptions, getDeliveryStatus);
}; 

如果它有效，请告诉我。
