Question

我有一个与Firebase连接的有角度的应用程序。到目前为止，我已经完成了数据库和身份验证。但是现在，我只能使用云功能。每当有人预订受益人时，我都会尝试通过nodemailer发送电子邮件。该功能代码大部分是从firebase github函数示例复制的像这样：

'use strict';

const functions = require('firebase-functions');
const nodemailer = require('nodemailer');
// Configure the email transport using the default SMTP transport and a GMail account.
// For other types of transports such as Sendgrid see https://nodemailer.com/transports/
// TODO: Configure the `gmail.email` and `gmail.password` Google Cloud environment variables.
const gmailEmail = functions.config().gmail.email;
const gmailPassword = functions.config().gmail.password;
const mailTransport = nodemailer.createTransport({
  service: 'gmail',
  auth: {
    user: gmailEmail,
    pass: gmailPassword,
  },
});

// Sends an email confirmation when a user changes his mailing list subscription.
exports.sendEmailConfirmation = functions.database.ref('/users/{uid}').onWrite(async (change) => {
  const snapshot = change.after;
  const val = snapshot.val();

  if (!snapshot.changed('subscribedToMailingList')) {
    return null;
  }

  const mailOptions = {
    from: '"Spammy Corp." <noreply@firebase.com>',
    to: val.email,
  };

  const subscribed = val.subscribedToMailingList;

  // Building Email message.
  mailOptions.subject = subscribed ? 'Thanks and Welcome!' : 'Sad to see you go :`(';
  mailOptions.text = subscribed ?
      'Thanks you for subscribing to our newsletter. You will receive our next weekly newsletter.' :
      'I hereby confirm that I will stop sending you the newsletter.';

  try {
    await mailTransport.sendMail(mailOptions);
    console.log(`New ${subscribed ? '' : 'un'}subscription confirmation email sent to:`, val.email);
  } catch(error) {
    console.error('There was an error while sending the email:', error);
  }
  return null;
});

此后，我将环境变量设置如下：

firebase functions:config:set gmail.email="myusername@gmail.com" gmail.password="secretpassword"

我在使用firebase服务时将我的功能部署到firebase时出现错误： -TypeError：无法读取未定义的属性“电子邮件”

当我检查firebase函数时：config：得到它向我显示正确的数据该Webapp本身尚未部署（可以吗？）

任何想法/帮助将不胜感激

Answer 1

如果您想使用firebase serve在本地进行功能仿真以获取环境变量，则需要遵循documentation中的以下说明：

如果您使用的是自定义函数配置变量，请运行在项目的功能目录中的以下命令之前运行Firebase服务。
firebase functions:config:get > .runtimeconfig.json
但是，如果您使用的是Windows PowerShell，请替换上面的命令与：
firebase functions:config:get | ac .runtimeconfig.json

Answer 2

为什么不使用.env目录中的functions文件？它会自动捕获环境变量。

Firebase函数环境变量无法读取未定义的属性
