在服务器端使用nodejs express服务器通过openid协议处理googleoauth，我试图让回调函数在google将用户重定向到带有auth code+in query string的api之后运行这个清单。
只允许与学校的特殊领域的电子邮件通过（这是一个学校的项目）。
交换包含身份验证令牌、刷新令牌等的令牌对象。
通过cookie存储身份验证令牌
将整个令牌对象通过redis缓存存储在json对象中。。。这就是我被抓的地方(使用redis模块rejson。因为可以将数据库中的用户数据添加到内存中的对象以缓存用户数据…）
接下来的逻辑步骤包括检查用户是否存在于mongodb中，如果不存在则在mongodb中创建用户，重定向到浏览器，携带cookie，使用auth token检查redis缓存以维护持久会话。。。最终将通过hash、httponly、https等实现安全。。。
希望这能让您了解我的逻辑，但这似乎是一个redis或redis相关模块的问题。
为了使用redis rejson模块，我正在运行一个redis redisjson docker映像，它暴露在端口6379上，而express服务器（在端口4000上运行）将成为redis缓存服务器的客户机。。。
节点模块redis rejson允许redisjson命令Map到javascript友好名称。节点模块redis是节点的redis客户端库。

//This is a minimalist web-framework for NodeJS
var express = require("express");

//axios - handles HTTP requests

//redis - use for caching
//rejson - store JSON via redis

      rejson(redis);

//set ports
const PORT = process.env.PORT || 4000;
const REDIS_PORT = process.env.PORT || 6379;

const client = redis.createClient(REDIS_PORT);

// Init Express app 
var app = express();

  //callback route from google

        return res.redirect(301, 'http://localhost:3000/?error=invalid_domain');
