Question

我正在使用Redis包用于Node.js（ioredis），我在ScaleGrid上托管了一个Redis集群，我试图从heroku连接到该集群，但是我一直收到错误[ioredis] Unhandled error event: Error: connect ECONNREFUSED 127.0.0.1:6379 at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1106:14) Redis Error: { ReplyError: NOAUTH Authentication required.。这是我的代码

//This is what my redis uri provided by ScaleGrid uri looks like, this is not exact string though
REDIS_URI=SG-Stack-12345.servers.mongodirector.com:6379

import session from 'express-session';
import Redis from 'ioredis';
import connectRedis from 'connect-redis';

const redisClient = process.env.REDIS_URI;

const redis = new Redis(redisClient);
const redisStore = connectRedis(session);

redis.on('error', (err) => {
  console.log('Redis Error:', err);
});

app.use(session({
  secret: process.env.SESSION_SECRET,
  name: '_redisSession',
  resave: false,
  saveUninitialized: true,
  cookie: { secure: false },
  store: new redisStore({ client: redis, ttl: 86400 }),
}));

请问我该如何解决这个问题？以及为什么我仍然得到这个Error: connect ECONNREFUSED 127.0.0.1:6379

PS Redis可以在我的本地主机上完美运行

我意识到我所需要的只是在Redis客户端连接(client.auth(password)之后立即发送用于身份验证的密码。我必须为redislabs enterprise做好自己的Redis托管服务，并且由于一些奇怪的错误，还不得不从ioredis软件包更改为redis软件包。这是下面的代码

redis.js

import { createClient } from 'redis';

const {
  PASSWORD: password,
  REDIS_HOST: host, // On localhost, set to 'localhost' or '127.0.0.1'
  REDIS_PORT: port, // On localhost,  set to 6379
} = process.env;

// connect to Redis host with port and host set as environment variables
const client = createClient(port, host, { no_ready_check: true });

// If password is in environment variable, send password to the host for authentication
if (password) {
  client.auth(password, (err) => {
    if (err) throw err;
  });
}

client.on('connect', () => console.log('connected to Redis'));

client.on('error', (err) => {
  console.log('Redis Error:', err);
});

export default client;

这是可选的，仅显示索引文件中如何使用连接的Redis客户端。

index.js

import session from 'express-session';
import connectRedis from 'connect-redis';
import client from './redis'

const redisStore = connectRedis(session);

app.use(session({
  secret: 'IwontTell',
  name: '_stackOverflow',
  resave: false,
  saveUninitialized: true,
  cookie: { secure: false },
  store: new redisStore({ client, ttl: 86400 }),
}));

这在localhost和联机上均有效。希望这对某人有帮助

我正在尝试从heroku连接到在线Redis服务器，但是我的连接被拒绝了
