javascript - 部署新更改后，Firebase 功能未显示

Question

我从示例函数复制了电子邮件确认云函数并将其部署到我的项目中，它可以工作，并且该函数显示在我的 Firebase 控制台中。

但是，当我根据需要自定义代码然后部署到 firebase 后，该函数就从我的 firebase 函数中消失了。

原代码为:

'use strict';

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,
  },
});

// Sends an email confirmation when a user changes his mailing list subscription.
exports.sendEmailConfirmation = functions.database.ref('/users/{uid}').onWrite((event) => {
  const snapshot = event.data;
  const val = snapshot.val();

  if (!snapshot.changed('subscribedToMailingList')) {
    return null;
  }

  const mailOptions = {
    from: '"Spammy Corp." <noreply@firebase.com>',
    to: val.email,
  };

  const subscribed = val.subscribedToMailingList;

  // Building Email message.
  mailOptions.subject = subscribed ? 'Thanks and Welcome!' : 'Sad to see you go :`(';
  mailOptions.text = subscribed ? 'Thanks you for subscribing to our newsletter. You will receive our next weekly newsletter.' : 'I hereby confirm that I will stop sending you the newsletter.';

  return mailTransport.sendMail(mailOptions)
    .then(() => console.log(`New ${subscribed ? '' : 'un'}subscription confirmation email sent to:`, val.email))
    .catch((error) => console.error('There was an error while sending the email:', error));
});

更新后的代码是:

'use strict';

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,
  },
});

// Sends an email confirmation when a user changes his mailing list subscription.
exports.sendEmailConfirmation = (req, res) => {
  if (req.body.subject === undefined || req.body.recipient === undefined) {
    // This is an error case, as "message" is required.
    //res.status(400).send('subject/body/recipient is missing!');
    return false
  } else {
      const mailSubject = req.body.subject;
      const mailHtmlBody = req.body.htmlBody;
      const mailRecipient = req.body.recipient;



      const mailOptions = {
        from: '"Food Ninja." <foodninjaapp@gmail.com>',
        to:  mailRecipient,
        subject: mailSubject,
        html: mailHtmlBody
      };

      //res.status(200).send('Success: ' + mailSubject + ' to ' + mailRecipient);

      return mailTransport.sendMail(mailOptions)
//        .then(() => console.log(`${mailSubject}subscription confirmation email sent to: `, mailRecipient))
//        .catch((error) => console.error('There was an error while sending the email:', error));
  }
};

到目前为止，我没有发现代码有任何问题，请指教。

我如何部署它:

firebase deploy

@Jerry 该函数不起作用，因为您已用自己的函数替换了该函数调用

functions.database.ref('/users/{uid}').onWrite

这一行是您的函数的触发器，所以自然地，该函数现在无法运行。

部署云功能时，请务必查看生成的日志。例如:如果您现在部署旧代码，日志将显示“sendEmailConfirmation 函数已创建”

如果您更新同一函数的内容，它将记录“sendEmailConfirmation 函数已更新”

如果您删除或删除该功能，它将记录，“sendEmailConfirmation 功能已删除”

希望这有帮助。

收到评论后进行编辑:

    exports.sendEmailConfirmation = functions.database.ref('/users/{uid}').onWrite((event) => {
          const snapshot = event.data;
          const val = snapshot.val();

          if (!snapshot.changed('subscribedToMailingList')) {
            return null;
          }

//instead of getting from the request, have the mail variables either in a firebase node or for now just hard code it. for email, get it from the variable val
    const mailSubject = "This is my mail subject";
          const mailHtmlBody ="this is a awesome mail";
          const mailRecipient = val.email;



          const mailOptions = {
            from: '"Food Ninja." <foodninjaapp@gmail.com>',
            to:  mailRecipient,
            subject: mailSubject,
            html: mailHtmlBody
          };




          return mailTransport.sendMail(mailOptions)
            .then(() => console.log(`New ${subscribed ? '' : 'un'}subscription confirmation email sent to:`, val.email))
            .catch((error) => console.error('There was an error while sending the email:', error));
        });
