redisclient's Introduction

实现方式

通过对底层redis client的封装，实现接口Client来提供redis常用的一些操作
当前封装的底层redis client是go-redis，git地址为https://github.com/go-redis/redis/tree/v7

实现目的

在底层redis client之上增加一层接口封装，该接口供上层调用，有利于代码的扩展性
在底层redis client发生替换或变化时，无需对Client接口协议协议进行变更，只需改变接口方法内的具体实现，增强了代码的可维护性

	})
	DBOps(sentinelClient)
}

func DBOps(cli redisclient.Client) {
	ctx := context.Background()
	key := "mykey"

	pipe := cli.Pipeline()
	pipe.Set("aaa", 99, 0)
	pipe.Get("aaa")
	vals, err := pipe.Exec()
	checkErr(err)
	fmt.Println("Pipeline", vals)

	err = cli.Set(ctx, key, "Hello,man!", 0).Err()
	checkErr(err)

	intVal, err := cli.Exists(ctx, key).Result()
	checkErr(err)
	fmt.Println("Exists", intVal)

	strVal, err := cli.Get(ctx, key).Result()
	checkErr(err)
	fmt.Println("Get", key, strVal)
}

func checkErr(err error) {
	if err != nil {
		if err == redis.Nil {
			return
