// 导包
const redis = require('redis');
// 配置信息
const RDS_PORT = 6379
const RDS_HOST = '127.0.0.1'
const RDS_OPTS = {}
// 连接redis
let client = redis.createClient(RDS_PORT, RDS_HOST, RDS_OPTS)


client.on('ready', () => {
    // console.log(client.values, client)
    // console.log('ready')
})

// 连接成功触发事件 
client.on('connect', () => {
    // client.flushall()
    // 变量存入redis 
    client.set('author0', 'user0', function (q,val) {
        console.log(val, 0)
    })
    client.set('author1', 'user1', function (q, val) {
        console.log(val, 0)
    })
    client.set('author2', 'user2', function (q, val) {
        console.log(val, 0)
    })
    getAllData(client)
    
    // 删除redis key
    client.DEL('author', redis.print)
    client.get('author', redis.print)

// 获取所有值
function getAllData(client) {
