我在试着和你联系 redis （指docker示例）使用 express(node.js) . 这是我的 index.ts 我正在尝试连接的文件 redis ```
import mongoose from 'mongoose'
import express from 'express'
import session from 'express-session'
import connectRedis from 'connect-redis'
import Redis from 'ioredis'
import { MONGO_URI, MONGO_OPTIONS, REDIS_OPTIONS, APP_PORT } from './config'
import { createApp } from './app';

; (async () => {
await mongoose.connect(MONGO_URI, MONGO_OPTIONS)

const RedistStore = connectRedis(session)

const client = new Redis(REDIS_OPTIONS)

const store = new RedistStore({ client })

const app = createApp(store)

app.listen(APP_PORT, () => console.log('server running on port 3000'))

})()

这是我的 `REDIS_OPTIONS` 我所有的文件 `redis` 选项。

import { RedisOptions } from 'ioredis'

const {
REDIS_PORT = 6379,
REDIS_HOST = 'localhost',
REDIS_PASSWORD = 'secret'
} = process.env

export const REDIS_OPTIONS: RedisOptions = {
port: +REDIS_PORT,
host: REDIS_HOST,
password: REDIS_PASSWORD
}
`docker-compose.yml`
version: '3'

services:
db:
user: $UID
image: mongo
ports:

environment:
MONGO_INITDB_ROOT: ''
MONGO_INITDB_PASSWORD: ''

MONGO_USERNAME: ''
MONGO_PASSWORD: ''
volumes:

- ./mongo-init.sh:/docker-entrypoint-initdb.d/mongo-init.sh:ro

cache:

ports:

command: ['--requirepass "secret"']
`package.json`

"stop": "docker-compose stop",
"down": "docker-compose down",
"dev": "npm run dev --prefix api"
},
"keywords": [],

}

现在，当我试图运行我的主应用程序文件，所以我得到这个错误

[ioredis] Unhandled error event: Error: connect ECONNREFUSED 127.0.0.1:6379 at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1106:14) node.js

我怎样才能摆脱这个错误？
