Node.js express无法在Heroku上设置cookies

const express = require('express');
const cookieParser = require('cookie-parser');
const session = require('express-session');

const app = express();

// 使用 cookie-parser 和 express-session 中间件
app.use(cookieParser());
app.use(session({
  secret: 'your-secret-key',
  resave: false,
  saveUninitialized: true,
  cookie: {
    secure: process.env.NODE_ENV === 'production', // 仅在生产环境中启用 Secure 属性
    sameSite: 'none' // 设置 SameSite 属性为 'none' 以允许跨站请求携带 cookies
  }
}));

app.get('/', (req, res) => {
  // 设置一个 cookie
  res.cookie('username', 'exampleUser', {
    maxAge: 900000,
    httpOnly: true,
    secure: process.env.NODE_ENV === 'production',
    sameSite: 'none'
  });
  res.send('Cookie has been set');
});

const PORT = process.env.PORT || 3000;
app.listen(PORT, () => {
  console.log(`Server is running on port ${PORT}`);
});
