javascript - 为什么 req.cookies 未定义？

Question

情况:

我正在尝试检查我的用户在向服务器发出请求时是否经过身份验证。

我用谷歌搜索了一下，发现了这个:

How to show different page if user is logged in via firebase

下面是我尝试使用这个库实现这个解决方案:

代码:

服务器端

  var cookies = require("cookie-parser");

  router.get("/", function(req, res, next){


      const { token } = req.cookies;

      console.log('Verifying token', token);


 });

客户端

<script src="/public/js/cookieScript.js"> </script>

<a href="/upload" class = "authIn uploadButton btn btn-success pull-right">UPLOAD</a>

<script>

        const setAppCookie = () => firebase.auth().currentUser &&
            firebase.auth().currentUser.getToken().then(token => {
                Cookies.set('token', token, {
                    domain: window.location.hostname,
                    expire: 1 / 24, // One hour
                    path: '/',
                    secure: true // If served over HTTPS
             });
        });

</script>

除了需要 cookie-parser 之外，您还应该配置您的 express 应用程序以使用它:

var express = require('express');
var app = express();
var cookies = require("cookie-parser");

app.use(cookies());
