# 如何使用Redis缓存
DartMars 封装了缓存操作类，可以直接执行 Redis 相关操作，满足大部分日常需求。
使用之前，先导入缓存操作类。
import 'package:project_name/bootstrap/redis/Redis.dart';

接下来，可以这样使用
//初始化类
Redis redis = Redis();
//连接Redis服务器
await redis.connect('localhost', 3379);
//验证
await redis.auth('123456');
//设置key
await reids.set('key', '1');
//获取key
dynamic res = await redis.get('key');
print(res);

请注意，大多数操作都需要通过返回值是否等于字符串 OK 来判断是否成功。
