如何将nodemailer与云端函数一起用于Firebase？ [英] How can I use nodemailer with Cloud Functions for Firebase?

问题描述

我正尝试在 nodemailer 。 /url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0ahUKEwiy3IXgpZfTAhXhB5oKHX3XDP8QFggaMAA&url=https%3A%2F%2Ffirebase.google Fireworks的云端函数，但不断出现错误，但似乎仍然不断因为smpt服务器无法到达或找到。我试过gmail，outlook和一个正常的托管smpt服务。它可以从我的本地节点服务器上运行。

这是从失败的尝试发送邮件时收到的记录错误：

  {
错误：getaddrinfoENOTFOUNDsmtp-mail.outlook.comsmtp-mail.outlook.com：587aterrnoException（dns.js：28：10）atGetAddrInfoReqWrap.onlookup [
 asoncomplete 
（dns.js：76：26）code：'ECONNECTION'，
 errno：'ENOTFOUND'，
 syscall：'getaddrinfo'，
 hostname：' smtp-mail.outlook.com'，
主机：'smtp-mail.outlook.com'，
端口：'587'，
命令：'CONN'
} 
  

如果有人有足够的名声，请用 firebase-cloud-functions 我创建了一个云端函数（http事件），通过以下方式从我的网站的联系表单部分发送电子邮件：http：//blog.csdn.net/shenzhen/article/details ：

  const functions = require（'firebase-functions'）; 
 const nodemailer = require（'nodemailer'）; 
 const rp = require（'request-promise'）; 
 
 //用于发送电子邮件的Google帐户凭证
 const mailTransport = nodemailer.createTransport（
`smtps：//[e-mail]：[e-mail] `）; 
 
 exports.sendEmailCF = functions.https.onRequest（（req，res）=> {
 
 //验证码验证
 rp（{
 uri：'https://recaptcha.google.com/recaptcha/api/siteverify'，
方法：'POST'，
 formData：{
秘密：'your_secret_key'，
 response：req.body ['g-recaptcha-response'] 
}，
 json：true 
}）。then（result => {
 if（result。 （（）=> {
 res.status（200）.send（true）; 
）{
 sendEmail（[e-mail]'，req.body） }）; 
} 
 else {
 res.status（500）.send（Recaptcha failed。）
} 
}）。catch（reason => ; {
 res.status（500）.send（Recaptcha req failed。）
}）
 
}）; 
 
发送邮件函数
函数sendEmail（email，body）{
 const mailOptions = {
 from：`< [e-mail]>`， 
到：email 
}; 
 // hmtl消息结构
 mailOptions.subject ='联系表单消息'; 
 mailOptions.html =`< p>< b>名称：< / b> $ {body.rsName}< / p> 
< p>< b>电子邮件：< / b> $ {body.rsEmail}< / p> 
< p>< b> Subject：< / b> $ {body.rsSubject}< / p> 
< p>< b>讯息：< / b> $ {body.rsMessage}< / p>`; 
返回mailTransport.sendMail（mailOptions）; 
} 
  

I'm trying to use nodemailer in a Cloud Functions for Firebase but keep getting errors seeming to be that the smpt server cant be reached or found. Iv'e tried gmail, outlook and a normal hosted smpt service. It works well from my local node server.

This is the logged error I receive from the failed attempt to send email:

{
  Error: getaddrinfoENOTFOUNDsmtp-mail.outlook.comsmtp-mail.outlook.com: 587aterrnoException(dns.js: 28: 10)atGetAddrInfoReqWrap.onlookup[
    asoncomplete
  ](dns.js: 76: 26)code: 'ECONNECTION',
  errno: 'ENOTFOUND',
  syscall: 'getaddrinfo',
  hostname: 'smtp-mail.outlook.com',
  host: 'smtp-mail.outlook.com',
  port: '587',
  command: 'CONN'
}

Could someone with enough reputation please tag this question with firebase-cloud-functions?

解决方案

I created a cloud function (http event) to send emails from the contact form section of my site with the following way:

const functions = require('firebase-functions');
const nodemailer = require('nodemailer');
const rp = require('request-promise');

//google account credentials used to send email
const mailTransport = nodemailer.createTransport(
    `smtps://[e-mail]:[e-mail]`);

exports.sendEmailCF = functions.https.onRequest((req, res) => {

  //recaptcha validation
  rp({
        uri: 'https://recaptcha.google.com/recaptcha/api/siteverify',
        method: 'POST',
        formData: {
            secret: 'your_secret_key',
            response: req.body['g-recaptcha-response']
        },
        json: true
    }).then(result => {
        if (result.success) {
            sendEmail('[e-mail]', req.body).then(()=> { 
              res.status(200).send(true);
            });
        }
        else {
            res.status(500).send("Recaptcha failed.")
        }
    }).catch(reason => {
        res.status(500).send("Recaptcha req failed.")
    })

});

// Send email function
function sendEmail(email, body) {
  const mailOptions = {
    from: `<[e-mail]>`,
    to: email
  };
  // hmtl message constructions
  mailOptions.subject = 'contact form message';
  mailOptions.html = `<p><b>Name: </b>${body.rsName}</p>
                      <p><b>Email: </b>${body.rsEmail}</p>
                      <p><b>Subject: </b>${body.rsSubject}</p>
                      <p><b>Message: </b>${body.rsMessage}</p>`;
  return mailTransport.sendMail(mailOptions);
}
