//创建redis连接
const client = redis.createClient({
  host:'localhost',
  port: 6379,
  password: ''
});

client.on('ready', error=>{
    if (error){
        console.log('error: ' + error);
    }else{
        console.log('redis connect success');
    }
});

client.on('connect', ()=>{
    //字符串类型操作
    client.set('aaa', 'Hello redis');
    client.get('aaa',(error, result)=>{
        if (error){
            console.log('error: '+ error);
        } else {
            console.log(result);
        }
    });

    //集合类型操作
    let key = 'bbb';
    client.sadd(key, 'c++');
    client.sadd(key, 'node.js');
    client.sadd(key, 'js');

    client.multi().smembers(key)
        .exec((error, result)=>{
        if (error){
            console.log('error: ' + error);
        } else {
            result.forEach((value, index)=>{
                console.log(value.toString());
            });
        }
    });
    client.quit();
});

client.on('end', err=>{
    console.log('redis end');
});
