部署新更改后,Firebase功能未显示

我从sample-function复制了一个电子邮件混淆云功能,并将其部署到我的项目中,它正常工作,该功能在我的firebase控制台中显示。

但是,在根据我的需要自定义代码然后部署到firebase之后,该函数就会从我的firebase函数中消失。

原始代码是:

'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 = 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,我没有看到代码有任何问题,请告知。

被修改

我如何部署它:

firebase deploy

以下是Cmder对新代码部署的响应:

@Jerry该函数无法正常工作,因为您已使用自己的函数替换此函数调用

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

这一行是你的函数的触发器,所以当然这个函数不能正常工作。

部署云功能时,请始终查看生成的日志。 例如:如果您现在部署旧代码,日志会说&#34; 创建sendEmailConfirmation函数&#34;

如果您更新同一功能的内容,它将记录,&#34; sendEmailConfirmation功能已更新&#34;

如果您删除或删除该功能,它将记录, &#34; sendEmailConfirmation功能已删除&#34;

希望这有帮助。

    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));
        });
