Firebase的云功能-onWrite发送电子邮件 [英] Cloud Functions for Firebase - Send email onWrite

问题描述

当在/emails 中写入任何内容时，我试图将测试电子邮件发送到我的电子邮件中，但是该电子邮件从未发送过且功能日志为空.

I m trying to send a test email to my email when anything is written in /emails but the email never gets sent and the function logs are empty.

exports.sendTestEmail = functions.database.ref('/emails')
  .onWrite(event => {
    return sendTestEmail('[e-mail]');
  })
// [END onWrite]

// Sends a welcome email to the given user.
function sendTestEmail(email) {
  const mailOptions = {
    from: `${APP_NAME} <[e-mail]>`,
    to: email
  };
  // The user subscribed to the newsletter.
  mailOptions.subject = `Welcome to ${APP_NAME}!`;
  mailOptions.text = `Hey there! Welcome to ${APP_NAME}. I hope you will enjoy our service.`;
  return mailTransport.sendMail(mailOptions).then(() => {
    console.log('New welcome email sent to:', email);
  });

}

编辑***

上面的代码有效.我试图在 emails 上触发功能，而正确的名称是 email .

The above code works. I was trying to trigger the function on emails while the correct name was email.
