我正在使用firebase云函数。我已配置以下设置。虽然这在我的本地机器上运行得很好,但在服务器上运行时却给了我一个问题。我在互联网上尝试了无数的工作,但没有成功。这有什么问题?

'use strict'
const functions = require('firebase-functions');
var admin = require('firebase-admin');
const express = require('express');
const nodemailer = require('nodemailer');
const app = express()

var emailRecepient;
var userName;


const smtpTransport = nodemailer.createTransport({
service: "gmail",
host: 'smtp.gmail.com',
port: 587, // tried enabling and disabling these, but no luck
secure: false, // similar as above
auth: {
  user: '<emailid>',
  pass: '<password>'
    },
        tls: {
        rejectUnauthorized: false
    }
});

var mailOptions = {
  from: 'test <hello@example.com>',
  to: emailRecepient,
  subject: 'Welcome to test',
  text: 'welcome ' + userName + ". did you see the new things?"
};

function sendmail() {
smtpTransport.sendMail(mailOptions, function (error, info) {
    if (error) {
        console.log(error);
    }
    else {
        console.log('Email sent: ' + info.response);
    }
});
};

exports.sendEmails = functions.database.ref('/users/{userID}/credentials').onCreate((snap, context) => {

  const userID = context.params.userID;
  const vals = snap.val()

  userName = vals.name;
  emailRecepient = vals.email;

  smtpTransport.sendMail(mailOptions, function (error, info) {
  if (error) {
      console.log("Error sending email ---- ",error);
  }
  else {
      console.log('Email sent: ' + info.response);
  }
  });

  return true;

});

我甚至已经转过身去了 allow secure apps in the google settings . 但出于某种原因,这似乎不起作用。非常感谢您的帮助。

firebase-samples/email-confirmation 我有以下错误:

当您在后台触发的云函数中执行异步操作时,必须返回一个承诺,以这种方式,云函数将等待该承诺解析以终止。

这在Firebase官方视频系列中得到了很好的解释: https://firebase.google.com/docs/functions/video-series/ . 特别是看三个名为“学习JavaScript承诺”的视频(第2部分和第3部分特别关注后台触发的云函数,但之前确实值得看第1部分)。

因此,您应该按如下方式修改代码:

exports.sendEmails = functions.database.ref('/users/{userID}/credentials').onCreate((snap, context) => {

  const userID = context.params.userID;
  const vals = snap.val()

  userName = vals.name;
  emailRecepient = vals.email;

  return smtpTransport.sendMail(mailOptions);
});

如果要将电子邮件发送的结果打印到控制台,可以执行以下操作:

  return smtpTransport.sendMail(mailOptions)
    .then((info) => console.log('Email sent: ' + info.response))
    .catch((error) => console.log("Error sending email ---- ", error));
});

实际上,有一个官方的云函数示例正是这样做的,请参见 https://github.com/firebase/functions-samples/blob/master/email-confirmation/functions/index.js

import * as admin from 'firebase-admin';
import * as functions from 'firebase-functions';
import * as nodemailer from 'nodemailer';

admin.initializeApp();

// I'm taking all these constants as secrets injected dynamically (important when you make `git push`), but you can simply make it as a plaintext.
declare const MAIL_ACCOUNT: string; // Declare mail account secret.
declare const MAIL_HOST: string; // Declare mail account secret.
declare const MAIL_PASSWORD: string; // Declare mail password secret.
declare const MAIL_PORT: number; // Declare mail password secret.

const mailTransport = nodemailer.createTransport({
  host: MAIL_HOST,
  port: MAIL_PORT, // This must be a number, important! Don't make this as a string!!
  auth: {
    user: MAIL_ACCOUNT,
    pass: MAIL_PASSWORD
  }
});

exports.sendMail = functions.https.onRequest(() => {
  const mailOptions = {
    from: 'ME <SENDER@gmail.com>',
    to: 'RECEIVER@gmail.com',
    subject: `Information Request from ME`,
    html: '<h1>Test</h1>'
  };
  mailTransport
    .sendMail(mailOptions)
    .then(() => {
      return console.log('Mail sent'); // This log will be shown in Firebase Firebase Cloud Functions logs.
    })
    .catch(error => {
      return console.log('Error: ', error); // This error will be shown in Firebase Cloud Functions logs.
    });
});

这就是说,您应该收到来自的电子邮件 SENDER@gmail.com RECEIVER@gmail.com

注意:我在网上正确发送邮件时遇到了同样的问题 localhost port 和 host 在里面 createTransport

const mailTransport = nodemailer.createTransport({
  service: 'gmail',
  auth: {
    user: MAIL_ACCOUNT,
    pass: MAIL_PASSWORD
  }
});

除此之外,不要忘记启用 Less secure app access 到 在…上 . 阿尔索 https://accounts.google.com/DisplayUnlockCaptcha

在检查了上面列出的所有事情都是在我的代码中完成的之后,我解决了在Google帐户中登录的问题(我在proyect中使用的帐户)。我必须从另一个来源(谷歌检测到Firebase试图访问该帐户)识别该活动,就是这样。
