Nodejs操作redis的一些常用命令[持续更新ing]

初始化redis

//连接redis
var redis = require('redis'),
  RDS_PORT = 6379,        //端口号
  RDS_HOST = '127.0.0.1',    //服务器IP
  RDS_OPTS = {},            //设置项
  //RDS_PWD = 'porschev',           //密码
  //RDS_OPTS = {auth_pass:RDS_PWD},            //设置项
  redClient = redis.createClient(RDS_PORT, RDS_HOST, RDS_OPTS);
  //选择哪个库
  redClient.select(1, function () {
  console.log('连接redis库1');
})

redClient.on('ready', function (res) {
  console.log('ready');
});

redClient.on('connect', function () {
  redClient.set('Hello', 'Redis');
  redClient.get('Hello', redis.print);
  console.log('Hello');
});

一些常用操作命令

//删除list的元素
redClient.lrem('list', 0, value, function (err, res) {
            if (err) {
              console.log(err);
            } else {
              console.log(res);
            }
          });

//判断是否存在key
redClient.EXISTS(key, function (err, replay) {
          if (err) return false;
          return replay;
        })
