我正在尝试从 heroku 连接到在线 redis 服务器，但我的连接被拒绝

Question

我正在使用 Node 的 Redis 包.js (ioredis(，我有一个托管在 ScaleGrid 上的 redis 集群，我试图从 heroku 连接到它，但我一直收到错误[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？ 还有为什么我仍然得到这个Error: connect ECONNREFUSED 127.0.0.1:6379

附言Redis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)后立即发送密码进行身份验证。 我不得不为我的 redis 托管redislabs enterprise，并且由于一些奇怪的错误ioredis也不得不从包更改为redis包。这是下面的代码

雷迪斯.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，它仅显示如何在索引文件中使用连接的 redis 客户端。

索引.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 }),
}));

这在本地主机和在线上都有效。希望这对某人有所帮助
