Question

我有一个Firebase数据库，其中onCreate Google Cloud Functions调用nodemailer并向我发送电子邮件。一切正常，但现在我也尝试在电子邮件中包括添加到数据库的数据。我无法使用它，似乎是因为它不是文本格式，并且我尝试了转换为文本，但似乎没有做到这一点。我在做什么错了？

const functions = require('firebase-functions');
const nodemailer = require('nodemailer');
// Configure the email transport using the default SMTP transport and a GMail account.
// For other types of transports such as Sendgrid see https://nodemailer.com/transports/
 // TODO: Configure the `gmail.email` and `gmail.password` Google Cloud environment variables.
const gmailEmail = functions.config().gmail.email;
const gmailPassword = functions.config().gmail.password;
const mailTransport = nodemailer.createTransport({
  service: 'gmail',
  auth: {
    user: gmailEmail,
    pass: gmailPassword,
  },
});

exports.sendWelcomeEmail =      functions.database.ref('/PickupRequests/{pushId}')
.onCreate(async(snapshot, context) => {

  const val = snapshot.data;

  const mailOptions = {
    from: '<noreply@firebase.com>',
    to: "mike@puravidalaundry.com",
    subject: "New Pickup Request",
    text: val //How do i convert this to a text format?
  };

  try {
    await mailTransport.sendMail(mailOptions);
    console.log('email sent');
  } catch(error) {
    console.error('There was an error while sending the email:',     error);
  }
  return null;
});

Answer 1

要从快照中获取值，请使用snapshot.val()。所以：

const val = snapshot.val();

请注意，这在handling event data for Realtime Database triggered Cloud Functions文档中的示例中显示。

Answer 2

弄清楚了。我必须创建一个新变量const newvar = JSON.stringify（val），然后说文本：newvar

电子邮件数据库结果
