Firebase Node.JS Admin SDK 发送验证电子邮件

Question

我正在使用 sdk 为该用户创建一个用户和一个数据库条目，这一切都可以完美运行。在创建数据库条目后，我调用了一个函数 sendEmailVerification() 但我猜这是一个客户端函数，因为它在被调用时返回 null。

直接从 admin sdk 发送验证电子邮件的过程是什么（如果可能的话）。目前我所做的是将一些 JSON 发送回客户端，以说明验证电子邮件是否发送成功。但是调用该函数不起作用，所以它没有那么远。这是我在节点中的函数。

function verifiyEmail(email, res) {

    var user = admin.auth().currentUser;
    user.sendEmailVerification().then(function() {


        // Email sent.
        var jsonResponse = {

            status: 'success',
            alertText: '1',
            email: email
        }

        res.send(jsonResponse); 

    }, function(error) {

        // An error happened.
        var jsonResponse = {

            status: 'success',
            alertText: '0',
            email: email
        }

        res.send(jsonResponse); 

    });

}

我猜这是不可能的，所以我在节点中生成了一个自定义令牌并将其发送回客户端。然后，我使用返回的令牌尝试通过调用以下命令登录用户，但不会调用 signInWithCustomToken() 函数。这是我的代码我错过了什么。发送验证邮件似乎需要做很多工作！

function signInUserWithToken(token) {

    firebase.auth().signInWithCustomToken(token).catch(function(error) {

      // Handle Errors here.
      var errorCode = error.code;
      var errorMessage = error.message;

      console.log(errorCode);
      console.log(errorMessage);

      verifiyEmail();

    });
}

我放弃了令牌的想法。我现在所做的就是使用 onAuthStateChanged() 函数并在客户端实现中处理电子邮件验证。它并不完美，因为此方法被多次调用。但是，添加标志似乎可以解决问题。如下所示。

function authListenerContractor() {
  // Listening for auth state changes.
  $('#not-verified').css('display','none'); 
  var flag = true;
  firebase.auth().onAuthStateChanged(function(user) {

        if (user) {

            // User is verified.
            var displayName = user.displayName;
            var email = user.email;
            var emailVerified = user.emailVerified;
            var photoURL = user.photoURL;
            var isAnonymous = user.isAnonymous;
            var uid = user.uid;
            var providerData = user.providerData;
            console.log("Email Verified?: " + emailVerified);

            if(emailVerified) {

                  window.location.href = "http://www.my-redirect-url.com";

            } else {

                if (flag == true) {

                    $('#not-verified').css('display','inherit');
                    verifiyEmail();

                    flag = false;
                }
            }

        } else {

            console.log("User is signed out.");
        }
   });
 }

function verifiyEmail() {

    var user = firebase.auth().currentUser;
    user.sendEmailVerification().then(function() {

        // Email sent.
        console.log("Verification email sent");
        $('#not-verified').text('**Email verification sent. Please check your email now!**');

    }, function(error) {

        // An error happened.
        console.log("Email verification not sent. An error has occurred! >>" + error);

    });
}

这是使用Firebase Cloud Functions的经典案例

发送欢迎邮件示例

const functions = require('firebase-functions');
const nodemailer = require('nodemailer');

const gmailEmail = encodeURIComponent(functions.config().gmail.email);
const gmailPassword = encodeURIComponent(functions.config().gmail.password);
const mailTransport = nodemailer.createTransport(
    `smtps://${gmailEmail}:${gmailPassword}@smtp.gmail.com`);


const APP_NAME = 'My App';


exports.sendWelcomeEmail = functions.auth.user().onCreate(event => {

  const user = event.data; // The Firebase user.

  const email = user.email; // The email of the user.
  const displayName = user.displayName; // The display name of the user.


  return sendWelcomeEmail(email, displayName);
});

function sendWelcomeEmail(email, displayName) {
  const mailOptions = {
    from: `${APP_NAME} <noreply@firebase.com>`,
    to: email
  };

  mailOptions.subject = `Welcome to ${APP_NAME}!`;
  mailOptions.text = `Hey ${displayName || ''}! Welcome to ${APP_NAME}. I hope you will enjoy our service.`;
  return mailTransport.sendMail(mailOptions).then(() => {
    console.log('New welcome email sent to:', email);
  });
}

// Sends a welcome email to the given user.

  mailOptions.subject = `Welcome to ${APP_NAME}!`;
