const redisPool = require('redis-connection-pool')('myRedisPool', {
    host: '127.0.0.1',
    options: {
        auth_pass: '123456'
    }
});

const setValue = (key, value) => {
    if (typeof value == 'string') {
        redisPool.set(key, value)
    } else if (typeof value == 'object') {
        redisPool.set(key, JSON.stringify(value))
    }
}

const getValue = (key) => {
    return new Promise((resolve, reject) => {
        redisPool.get(key, (err, res) => {
            if (err) {
                reject(err)
            } else {
                resolve(JSON.parse(res))
            }
        })
    })
}

module.exports = {
    setValue,
    getValue,
    redisPool
}



使用：

setValue('name','tom');

getValue('name').then(res=>{
    console.log(res);
}).catch(err=>{
    throw new Error(err)
})
