Question

我有以下云功能，尝试使用sendgrid在新用户注册时发送电子邮件。这是关于如何使用nodemailer发送电子邮件的原始firebase repo的修改版本。这在早期工作正常，没有sendgrid功能。因此，您在下面看到的是代码的大量修改版本。

'use strict';

const functions = require('firebase-functions');
const nodemailer = require('nodemailer');
const SEND_GRID_API_KEY = functions.config().sengrid.key


const sgMail = require('@sengrid/mail');
sgMail.setApiKey(SEND_GRID_API_KEY);




// Your company name to include in the emails
// TODO: Change this to your app or company name to customize the email sent.
const APP_NAME = 'Asia Rubber';

// [START sendWelcomeEmail]
/**
 * Sends a welcome email to new user.
 */
// [START onCreateTrigger]
exports.sendWelcomeEmail = functions.auth.user().onCreate((event) => {
  // [END onCreateTrigger]
  // [START eventAttributes]
  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.
  // [END eventAttributes]

  return sendWelcomeEmail(email, displayName);
});
// [END sendWelcomeEmail]

// [END sendByeEmail]

// Sends a welcome email to the given user.
function sendWelcomeEmail(email, displayName) {
  const msg = {
    from: `${APP_NAME} <Welcome@rubber.asia>`,
    to: email,
    subject: 'Welcome to ${APP_NAME}!',


    //custom templates
    templateId: 'e3978a51-5343-4b3a-9128-8c4a493f265e'
  };
  return sgMail.send(msg)
  .then( () => console.log('email sent'))
.catch(err => console.log(err))
}

当我尝试部署时，我收到错误

PS E:\Cloudfunctions\erubberFunctions\functions> firebase deploy --only functions

=== Deploying to 'erubber'...

所以，从我的代码中我唯一的密钥是sendgrid api密钥，我已经像这样添加了

firebase functions:config:set sendgrid.key=SG.YOUR_API_KEY

键没有引号btw。

我做错了什么？一般来说，代码一般有什么问题吗？ TKS

Answer 1

你的云功能有一个小错字。您正在尝试访问该媒体资源sengrid（在d中遗漏send）。

正确的代码行应该是;

const SEND_GRID_API_KEY = functions.config().sendgrid.key

尽管添加了触发器
