在 Angular 2 应用程序中从 Cloud Functions for Firebase 发送 mailgun 电子邮件

Question

我正在尝试使用 Mailgun 的 api 从 firebase 云功能发送电子邮件。我已经尝试在 Cloud Function 中实现相同的 nodejs 教程，但我总是得到“错误：无法处理请求”。请问我做错了什么。

云函数代码如下：

 <pre>
  <code>
 var functions = require('firebase-functions');

 var nodemailer = require('nodemailer');

  var auth = {
  auth: {
      api_key: '###################',
       domain: 's###############g'
   }
 }
 exports.helloWorld = functions.https.onRequest((request, response) => {
  response.send("Hello from Firebase!");
  });

   var nodemailerMailgun = nodemailer.createTransport(auth);

 exports.sendEmail = functions.https.onRequest((request, response) =>{
  //app.get('/', function(req, res) {
   test();
 });

  function test(){
     const mailOptions = {
        //Specify email data
            from: "info@xyz.com",
            //The email to contact
        to: "xyz@yahoo.com",
        //Subject and text data  
        subject: 'Hello from Mailgun',
        text: 'Hello, This is not a plain-text email, I wanted to test        some spicy Mailgun sauce in NodeJS! <a href="http://0.0.0.0:3030/validate?' +     req.params.mail + '">Click here to add your email address to a mailing     list</a>'
   };
    return smtpTransport.sendMail(mailOptions).then(() => {
    console.log("It works");
  });
}
</pre>

谢谢你的协助。

正如@GokulKathirvel 所述，只有付费帐户才会发送出站电子邮件。但我能够证明功能仪表板中的功能。触发该函数时，您将收到以下消息：

未配置结算帐户。外部网络无法访问并且 名额受到严格限制。配置结算帐户以删除这些 限制

除此之外，您还应该能够使用节点包mailgun-js 来做到这一点。

var functions = require('firebase-functions')
var mailgun = require('mailgun-js')({apiKey, domain})

exports.sendWelcomeEmail = functions.database.ref('users/{uid}').onWrite(event => {

  // only trigger for new users [event.data.previous.exists()]
  // do not trigger on delete [!event.data.exists()]
  if (!event.data.exists() || event.data.previous.exists()) {
    return
  }

  var user = event.data.val()
  var {email} = user

  var data = {
    from: 'app@app.com',
    subject: 'Welcome!',
    html: `<p>Welcome! ${user.name}</p>`,
    'h:Reply-To': 'app@app.com',
    to: email
  }

  mailgun.messages().send(data, function (error, body) {
    console.log(body)
  })
})
