Cacher 缓存接口

type Redis

type Redis struct {
	Pool *redis.Pool
}

func Default

func Default(host string, port int, password ...string) *Redis

func New

func New(pool *redis.Pool) *Redis

func (*Redis) Close

func (r *Redis) Close()

Close 关闭redis 链接

func (*Redis) Delete

func (r *Redis) Delete(key string)

Delete 删除key

func (*Redis) Exists

func (r *Redis) Exists(key string) bool

Exists 判断key是否存在

func (*Redis) Get

func (r *Redis) Get(key string, target interface{}) bool

Get 根据key获取值 如果存在key，则返回值，true，如果不存在，返回nil，false

func (*Redis) GetBool

func (r *Redis) GetBool(key string) bool

func (*Redis) GetConn

func (r *Redis) GetConn() redis.Conn

GetConn 获取链接

func (*Redis) GetFloat64

func (r *Redis) GetFloat64(key string) float64

func (*Redis) GetInt

func (r *Redis) GetInt(key string) int

func (*Redis) GetString

func (r *Redis) GetString(key string) string

func (*Redis) Set

func (r *Redis) Set(key string, value interface{})

Set 放置值

func (*Redis) SetExpired

func (r *Redis) SetExpired(key string, value interface{}, expire time.Duration)

SetExpired 放置值 如果value 为非 golang 基本类型，则转换成, 如果 expire 为<=0，那么不设置过期时间
