最近在学习Node.js，记录下Node连接redis基本操作

# mac安装
brew install redis# 修改配置文件 /usr/local/etc/redis.conf
requirepass password# bind 127.0.0.1 如果需要可放开# 启动
redis-server &# 停止
kill -9 PID
redis-cli shundown# 项目中npm install redis

var redis = require('redis');var port = 6379;
var host = '127.0.0.1';
var password = '111111';var client = redis.createClient(port, host);// 如果redis没开启验证,可不写
// client.auth(password, function (e) {
//     console.log(e)
// })// 设置key的value
function setKey(key, value, callback) {client.on('connect', function () {client.set(key, value, callback);})
}
// 得到key的value
function getKey(key, callback) {client.on('connect', function () {client.get(key, callback);})
}
// 设置key对象的field属性的value
function hset(hash, key, value, callback) {client.on('connect', function() {client.hset(hash, key, value, callback);})
}
// 得到key对象的field属性的value
function hget(hash, key, callback) {client.on('connect', function() {client.hget(hash, key, callback);})
}
//得到key对象的所有的属性和值
function hgetall(hash, callback) {client.on('connect', function() {client.hgetall(hash, callback);})
}
// 同时将多个 field-value (域-值)对设置到哈希表 key 中
function hmset(hash, paramArr, callback) {client.on('connect', function() {client.hmset(hash, ...paramArr, callback);})
}
/*** keys * 得到所有key* hdel key field 删除* hexists key field 判断对象是否存在这个field*/module.exports = {setKey, getKey, hset, hget, hgetall, hmset
}

var redisUtil = require('./index')redisUtil.setKey('key1', '123456', function (err, rep) {console.log(rep)
})
