您应将其应用于heroku设置->配置变量->添加REDIS_URL。并且，最好在heroku附加组件中找到并应用redis cloud。

您如何使用节点js中的redis会话设置heroku redis

我正在努力让heroku redis在Node.js上工作...我创建了一个具有注册登录并查看计划的基本应用程序。我所有的终点都是邮递员，当我点击登录路径时，我会收到一个cookie。如下图所示。在本地，我在邮递员中获取cookie，并在我的应用程序浏览器中获取。

enter image description here这是邮递员cookie的图像。

下面是我的开发代码的片段。

const express = require("express");
const session = require("express-session");
const redis = require("redis");
const client = redis.createClient();
const redisStore = require("connect-redis")(session);
const cors = require("cors");
const cookieParser = require("cookie-parser");
const authRouter = require("../Auth/authRouter");
const plansRouter = require("../Plans/plansRouter");

// const redis = require("redis");
// if (process.env.NODE_ENV == "production") {
//   client = redis.createClient(process.env.REDIS_URL);
// } else {
//   client = redis.createClient();
// }

const server = express();
server.use(
  cors({
    credentials: true,
    origin: "http://localhost:3000"
  })
);
server.use(express.json());
server.use(cookieParser("this is my secret"));
server.use(
  session({
    secret: "this is my secret",
    name: "sequelize",
    unset: "destroy",
    rolling: true,
    credentials: "include",
    cookie: { secure: false },
    store: new redisStore({
      host: "localhost",
      port: 6379,
      client: client,
      ttl: 86400
    }),
    saveUninitialized: false,
    resave: false
  })
);
server.use("/auth", authRouter);
server.use("/plans", plansRouter);
console.log(client);

client.on("connect", () => {
  console.log(`\n ** Redis client connected ** \n`);
});
client.on("error", function(err) {
  console.log("Something went wrong " + err);
});

module.exports = server;
