我遵循了authorized-https-endpoint的示例，只添加了console.log来打印req.cookies，问题是cookies总是空的{}我使用客户端JS调用设置cookies并且它们确实保存但由于某种原因，我可以不要让他们在服务器端。
这是 index.js 的完整代码，它与示例完全相同：
'use strict';
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);
const express = require('express');
const cookieParser = require('cookie-parser')();
const cors = require('cors')({origin: true});
const app = express();
const validateFirebaseIdToken = (req, res, next) => {
console.log(req.cookies); //// <----- issue this is empty {} why??
next();
};
app.use(cors);
app.use(cookieParser);
app.use(validateFirebaseIdToken);
app.get('/hello', (req, res) => {
res.send(`Hello!!`);
});
exports.app = functions.https.onRequest(app);
存储饼干：
curl http://FUNCTION_URL/hello --cookie "__session=bar" // req.cookies =
{__session: bar}
不存储：
curl http://FUNCTION_URL/hello --cookie "foo=bar" // req.cookies =
{}
