当用户登录时，我在响应中发送回一个HttpOnly cookie。

然而，当我尝试读取cookie时，当我对API进行后续调用时，什么都没有
以下是我如何制作饼干的：

var signOptions = {
    expiresIn: '30d',
    algorithm: 'RS256'
  }
  var CurrentDate = new Date()
  CurrentDate.setMonth(CurrentDate.getMonth() + 1)
  var cookieOptions = {
    httpOnly: true,
    expires: CurrentDate
  }

  const token = jwt.sign({ _id: user._id },
    fs.readFileSync(path.resolve('routes/keys/private.key'), 'utf8'),
    signOptions)

  res.status(200).cookie('stickyAccessJwt', token, cookieOptions).send('well done')

路径（'/test'）：

const express = require('express')
const router = express.Router()
const { CheckAuthorisation } = require('./middleware/checkAuthorisation')

router.get('/', CheckAuthorisation, async (req, res) => {
  res.send(':)')
})

module.exports = router

中间件（401在这里到达）：

let checkAuthorisation = (req, res, next) => {
  var userJWT = req.cookies.stickyAccessJwt
  if (!userJWT) {
    res.status(401).send('Invalid or missing authorization token')
  } else {
    // 2. There's a token; see if it is a valid one and retrieve the payload

    var verifyOptions = {
      expiresIn: '30d',
      algorithm: ['RS256']
    }

    const userJWTPayload = jwt.verify(
      userJWT,
      fs.readFileSync(path.resolve('routes/keys/private.key'), 'utf8'),
      verifyOptions)

    if (!userJWTPayload) {
      // Kill the token since it is invalid
      res.clearCookie('stickyAccessJwt')
      res.status(401).send('Kill the token since it is invalid')
    } else {
      // 3. There's a valid token...see if it is one we have in the db as a logged-in user
      User.findOne({ '_id': userJWTPayload._id })
        .then(function (user) {
          if (!user) {
            res.status(401).send('User not currently logged in')
          } else {
            console.log('Valid user:', user.email)
            next()
          }
        })
    }
  }
}

这是我的index.js

const Joi = require('joi')
Joi.objectId = require('joi-objectid')(Joi)
const bodyParser = require('body-parser')
const cors = require('cors')
const cookieParser = require('cookie-parser')
const mongoose = require('mongoose')
const express = require('express')
const app = express()
const register = require('./routes/register')
const login = require('./routes/login')
const test = require('./routes/test')

mongoose.connect('mongodb://localhost/stickywall', { useNewUrlParser: true })
  .then(() => console.log('Now connected to MongoDB!'))
  .catch(err => console.error('Something went wrong', err))
mongoose.set('useCreateIndex', true)

app.use(cors())
app.use(cookieParser())
app.use(express.json())
app.use(bodyParser.json())
app.use(bodyParser.urlencoded({ extended: true }))
app.use('/register', register)
app.use('/login', login)
app.use('/test', test)

const port = process.env.PORT || 4000
app.listen(port, () => console.log(`Listening on port ${port}...`))

我不明白为什么req.cookies是空的，是不是我遗漏了什么？
