我正在构建一个使用 Firestore 作为其数据库的 React 应用程序，并且我将 Google Cloud Functions 设置为在使用 nodemailer 将新文档添加到数据库中的某个集合时向用户发送电子邮件。发出的电子邮件需要包含个性化数据，即 - 你好，${user}!，我不确定在这种情况下如何将该数据注入 HTML。我目前有一个单独的 HTML 文件，我正在使用 fs.readFileSync 将其注入到 nodemailer 传输器中，但我被卡住了并正在寻找意见/建议。我的代码如下。谢谢！
index.js
const nodemailer = require("nodemailer");
const functions = require("firebase-functions");
const admin = require("firebase-admin");
const fs = require("fs");
admin.initializeApp();
// // Create and deploy your first functions
// // https://firebase.google.com/docs/functions/get-started
const transporter = nodemailer.createTransport({
service: "gmail",
auth: {
user: "*********",
pass: "*********",
},
});
const emailHTML = fs.readFileSync("./invite.html");
exports.sendSubRequest = functions.firestore.document("/subRequests/{id}")
.onCreate((snap, context) => {
console.log(snap.data());
console.log(emailHTML);
const inviteList = snap.data().invite;
inviteList.forEach((contact) => {
const mailOptions = {
from: "Weam <[email protected]>",
to: contact,
subject: "You've been invited to a game!",
html: emailHTML,
};
// returning result
return transporter.sendMail(mailOptions, (error, info, response) => {
if (error) {
return response.send(error.toString());
}
return response.send("Sent");
});
});
});
