通过谷歌云函数发送电子邮件会触发不稳定的语法错误

Question

在这些例子之后，我正在尝试使用谷歌云函数发送电子邮件：https://github.com/firebase/functions-samples/tree/master/quickstarts/email-users和 https://angularfirebase.com/lessons/sendgrid-v3-nodejs-transactional-email-cloud-function/然后我不得不做一些调整以适应发展中的技术，我的结果是这样的：

const functions = require('firebase-functions');
const cors = require('cors')({ origin: true });
const sendGrid = require('@sendgrid/mail');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);
const db = admin.firestore();
const SENDGRID_API_KEY="***";
sgMail.setApiKey(SENDGRID_API_KEY);
sendGrid.setApiKey(functions.config().sendgrid.apikey);
sendGrid.setSubstitutionWrappers('{{', '}}');
exports.httpEmail = functions.https.onRequest((req, res) => {
cors( req, res, () => { 
const name  = req.body.toName;
const email = req.body.Email;
const id = req.body.ID;
const msg = {
    to: email,
    from: [e-mail]',
    subject: id,
    text: `Hello {{name}}`,
    html: `<h1>Hello {{name}}</h1>`
};
return sgMail.send(msg)
    .then(() => res.status(200).send('email sent!') )
    .catch(err => res.status(400).send(err) )
});});

现在这给了我一个语法错误

/user_code/index.js：20 to： {{email}}， ^ 语法错误：意外的标记

{
  "name": "email",
  "description": "sending emails",
  "version": "0.0.1",
    "dependencies": {
    "sendgrid/mail": "^6.3.1",
    "cors": "^2.8.1",
    "moment": "^2.17.1",
    "firebase-admin": "~5.11.0",
    "firebase-functions": "^1.0.0"
  },
  "scripts": {
    "lint": "./node_modules/.bin/eslint --max-warnings=0 .",
    "serve": "firebase serve --only functions",
    "shell": "firebase experimental:functions:shell",
    "start": "npm run shell",
    "deploy": "firebase deploy --only functions",
    "logs": "firebase functions:log"
  },
  "private": true
}

这给了我一个解析错误：

无法解析 package.json，第 7 行第 6 列出错

这两个错误对我来说都没有意义，我不得不进行 4 种不同的调整，这让我怀疑我是否走在正确的道路上。有人有一个工作示例或教程，包括cors，带有变量的文本和sendgrid？或者有人可以为我解决错误消息吗？

Answer 1

1. 第一个错误是由于mail@homepage'中没有开场白
2. 其次可能是sendgrid/mail之前没有"@"，或者"dependencies"下没有缩进

虽然sendgrid是一个不错的选择，但您也可以查看 nodemailer .它不需要 API 密钥。这两种方法的工作方式相同，如以下示例所示。

app.yaml

runtime: nodejs8

包.json

{
  "dependencies": {
    "nodemailer": "^4.0.1",
    "@sendgrid/mail": "^6.3.1"
  }
}

应用.js

const nodemailer = require('nodemailer');
const sendgridmail = require('@sendgrid/mail');
exports.sendEmail = (req, res) => {
  // destination email passed as argument
  var email = req.query.message;
  // sender email config (mailserver)
  var gmailEmail = process.env.EMAIL;
  var gmailPassword = process.env.PASSWORD;

  // Nodemailer config
  var mailTransport = nodemailer.createTransport({
    service: 'Gmail',
    auth: {
      user: gmailEmail,
      pass: gmailPassword
    }
  });
  var msg = {
    from: gmailEmail,
    to: email,
    subject: 'Nodemailer',
    text: 'Sent with Nodemailer'
  };
  mailTransport.sendMail(msg);
  // Sendgrid config
  sendgridmail.setApiKey(process.env.GRIDKEY);
  var msg = {
    from: gmailEmail,
    to: email,
    subject: 'Sendgrid',
    text: 'Sent with Sendgrid/mail'
  };
  sendgridmail.send(msg);
  return `Sent two emails with Sendgrid and Nodemailer`;
};

注意：由于我使用Gmail作为邮件服务器，因此需要两个额外的步骤才能从中发送电子邮件：

1. 允许安全性较低的应用
2. 允许访问您的谷歌帐户
