Firebase 环境配置不起作用

Question

Firebase 环境变量似乎未定义，即使我按照文档进行了所有操作。

我根据这样的文档设置了我的 firebase 环境：

firebase functions:config:set mailerlite.key='12345' mailerlite.groupid='id123'

通过在我的终端中输入此 CLI

firebase functions:config:get

我找回来了

{
  "mailerlite": {
    "key": "12345",
    "id": "id123"
  }
}

到目前为止一切顺利。但我无法从我的 express.js 访问它。这是我的函数/index.js：

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

const express = require('express');
const bodyParser = require('body-parser');
const fetch = require("node-fetch");
const sensitive = require('./sensitive.js');
var cors = require('cors');


const app = express();


var allowedOrigins = ['http://localhost:8081',
    'https://myapp.com'];
app.use(cors({
    origin: function (origin, callback) {
        // allow requests with no origin 
        // (like mobile apps or curl requests)
        if (!origin) return callback(null, true);
        if (allowedOrigins.indexOf(origin) === -1) {
            var msg = 'The CORS policy for this site does not ' +
                'allow access from the specified Origin.';
            return callback(new Error(msg), false);
        }
        return callback(null, true);
    }
}));
app.use(bodyParser.urlencoded({ extended: true }));
const port = 3000
app.post('/subscribe', (req, res, next) => {

    console.log('key', functions.config().mailerlite.key);
    console.log('stringify', JSON.stringify(req.body));
    console.log('req.body: ', req.body);
    //console.log('req.body.email', req.body.email);

    (async function () {
        try {
            const mailerLiteResponse = await fetch('https://api.mailerlite.com/api/v2/groups/' + sensitive.groupId + '/subscribers', {
                method: 'POST',
                mode: 'Cors',
                headers: {
                    'content-type': 'application/json',
                    'X-MailerLite-ApiKey': functions.config().mailerlite.key,
                },
                body: JSON.stringify(req.body)

            });



            const responseJson = await mailerLiteResponse.json();

            res.status(mailerLiteResponse.status).send(mailerLiteResponse.body);

            console.log('mailer response: ', responseJson);
            console.log('key2', functions.config().mailerlite.key);
        } catch (err) {
            return next(err)
        }
    })();
});

app.listen(port, () => {
    console.log(`App listening at http://localhost:${port}`)
})

exports.app = functions.https.onRequest(app);

一旦我运行服务器，这就是我得到的响应：

你有一个更大的问题，只是功能配置。

首先，根本不可能在 Cloud Functions 中侦听端口。这在部署时根本不起作用：

app.listen(port, () => {
    console.log(`App listening at http://localhost:${port}`)
})

Cloud Functions 将安排监听您，并在收到请求时调用您的 API 端点。您只需导出您的 express 应用程序，它就会将其连接到托管套接字。

在对环境配置进行任何操作之前，我建议让您的 express 应用使用一个简单的示例，如 documentation 中所述，然后稍后将配置添加到其中。
