使用Node.js和bluebird读取Redis数据

我用bluebird重写了以下程序。使用Node.js：Async/Await来读取Redis数据。

安装图书馆。

sudo npm install -g bluebird

#! /usr/bin/node
// ---------------------------------------------------------------
//
//  bluebird_read.js
//
//                  Dec/30/2020
// ---------------------------------------------------------------
'use strict'

const bluebird = require("bluebird")
const redis = require('redis')
bluebird.promisifyAll(redis.RedisClient.prototype)
bluebird.promisifyAll(redis.Multi.prototype)

// ---------------------------------------------------------------
async function proc01 ()
{
    const redisUrl = 'redis://127.0.0.1:6379'
    const client = redis.createClient(redisUrl)

    const keys = await client.keysAsync('*')

    keys.forEach(async function(key,index)
        {
        const value = await client.getAsync(key)
        console.log(key,value)
        })

    await client.quitAsync()
}

// ---------------------------------------------------------------
console.error ("*** 開始 ***")
proc01()
console.error ("*** 終了 ***")

// ---------------------------------------------------------------

执行脚本

export NODE_PATH=/usr/lib/node_modules
./bluebird_read.js
