Options options to initiate your client
func NewRedisClient ¶ added in v3.4.2
func (*Client) ACLLogReset ¶ added in v3.6.4
func (*Client) Append ¶
Append 如果 key 已经存在并且是一个字符串, APPEND 命令将 value 追加到 key 原来的值的末尾。 如果 key 不存在, APPEND 就简单地将给定 key 设为 value ,就像执行 SET key value 一样。
func (*Client) BLPop ¶
func (r *Client) BLPop(ctx context.Context, timeout time.Duration, keys ...any) (val []string, err error)
BLPop 是列表的阻塞式(blocking)弹出原语。 它是 LPop 命令的阻塞版本,当给定列表内没有任何元素可供弹出的时候,连接将被 BLPop 命令阻塞,直到等待超时或发现可弹出元素为止。 当给定多个 key 参数时,按参数 key 的先后顺序依次检查各个列表,弹出第一个非空列表的头元素。
func (*Client) BRPop ¶
func (r *Client) BRPop(ctx context.Context, timeout time.Duration, keys ...any) (val []string, err error)
BRPop 是列表的阻塞式(blocking)弹出原语。 它是 RPOP 命令的阻塞版本,当给定列表内没有任何元素可供弹出的时候,连接将被 BRPOP 命令阻塞,直到等待超时或发现可弹出元素为止。 当给定多个 key 参数时,按参数 key 的先后顺序依次检查各个列表,弹出第一个非空列表的尾部元素。 关于阻塞操作的更多信息,请查看 BLPOP 命令, BRPOP 除了弹出元素的位置和 BLPOP 不同之外,其他表现一致。
func (*Client) BRPopLPush ¶
func (r *Client) BRPopLPush(ctx context.Context, source, destination any, timeout time.Duration) (val string, err error)
BRPopLPush 是 RPOPLPUSH 的阻塞版本,当给定列表 source 不为空时, BRPOPLPUSH 的表现和 RPOPLPUSH 一样。 当列表 source 为空时, BRPOPLPUSH 命令将阻塞连接,直到等待超时,或有另一个客户端对 source 执行 LPUSH 或 RPUSH 命令为止。
func (*Client) BZPopMax ¶
func (r *Client) BZPopMax(ctx context.Context, timeout time.Duration, keys ...any) (val *redis.ZWithKey, err error)
BZPopMax 是有序集合命令 ZPOPMAX带有阻塞功能的版本。
func (*Client) BZPopMin ¶
func (r *Client) BZPopMin(ctx context.Context, timeout time.Duration, keys ...any) (val *redis.ZWithKey, err error)
BZPopMin 是有序集合命令 ZPOPMIN带有阻塞功能的版本。
func (*Client) BgRewriteAOF ¶
BgRewriteAOF 异步重写附加文件
func (*Client) BitCount ¶
func (r *Client) BitCount(ctx context.Context, key any, bitCount *redis.BitCount) (val int64, err error)
BitCount 计算给定字符串中,被设置为 1 的比特位的数量。 一般情况下,给定的整个字符串都会被进行计数,通过指定额外的 start 或 end 参数,可以让计数只在特定的位上进行。 start 和 end 参数的设置和 GETRANGE 命令类似,都可以使用负数值:比如 -1 表示最后一个位,而 -2 表示倒数第二个位,以此类推。 不存在的 key 被当成是空字符串来处理,因此对一个不存在的 key 进行 BITCOUNT 操作,结果为 0 。
func (*Client) BitPos ¶
func (r *Client) BitPos(ctx context.Context, key any, bit int64, pos ...int64) (val int64, err error)
BitPos -> BitCount
func (*Client) BitPosSpan ¶ added in v3.6.12
func (*Client) ClientGetName ¶

func (*Client) ClientInfo ¶ added in v3.6.1
func (*Client) ClientKill ¶
ClientKill 杀掉客户端的连接
func (*Client) ClientKillByFilter ¶
ClientKillByFilter is new style synx, while the ClientKill is old CLIENT KILL <option> [value] ... <option> [value]
func (*Client) ClientList ¶
ClientList 获取客户端连接列表
func (*Client) ClientPause ¶
ClientPause 停止处理来自客户端的命令一段时间
func (*Client) ClientUnblock ¶ added in v3.2.31
func (*Client) ClientUnblockWithError ¶ added in v3.2.31
func (*Client) ClientUnpause ¶ added in v3.2.31
ClientPause 停止处理来自客户端的命令一段时间

func (*Client) ClusterCountKeysInSlot ¶
ClusterCountKeysInSlot Return the number of local keys in the specified hash slot
func (*Client) ClusterDelSlots ¶
ClusterDelSlots Set hash slots as unbound in receiving node
func (*Client) ClusterDelSlotsRange ¶

func (*Client) ModuleLoadex ¶ added in v3.6.1
func (*Client) Move ¶
Move 将当前数据库的 key 移动到给定的数据库 db 当中。 如果当前数据库(源数据库)和给定数据库(目标数据库)有相同名字的给定 key ,或者 key 不存在于当前数据库,那么 MOVE 没有任何效果。

func (*Client) PExpireTime ¶ added in v3.5.4
func (*Client) PTTL ¶
PTTL 这个命令类似于 TTL 命令,但它以毫秒为单位返回 key 的剩余生存时间,而不是像 TTL 命令那样,以秒为单位。 当 key 不存在时,返回 -2 。 当 key 存在但没有设置剩余生存时间时,返回 -1 。 否则,以毫秒为单位,返回 key 的剩余生存时间。
func (*Client) Persist ¶
Persist 移除给定 key 的生存时间,将这个 key 从『易失的』(带生存时间 key )转换成『持久的』(一个不带生存时间、永不过期的 key )。 当生存时间移除成功时,返回 1 . 如果 key 不存在或 key 没有设置生存时间,返回 0 。
func (*Client) Ping ¶
Ping 使用客户端向 Redis 服务器发送一个 PING ,如果服务器运作正常的话,会返回一个 PONG 。 通常用于测试与服务器的连接是否仍然生效,或者用于测量延迟值。 如果连接正常就返回一个 PONG ,否则返回一个连接错误。

func (*Client) RPopLPush ¶
RPopLPush 命令 RPOPLPUSH 在一个原子时间内,执行以下两个动作: 将列表 source 中的最后一个元素(尾元素)弹出,并返回给客户端。 将 source 弹出的元素插入到列表 destination ,作为 destination 列表的的头元素。 举个例子,你有两个列表 source 和 destination , source 列表有元素 a, b, c , destination 列表有元素 x, y, z ,执行 RPOPLPUSH source destination 之后, source 列表包含元素 a, b , destination 列表包含元素 c, x, y, z ,并且元素 c 会被返回给客户端。 如果 source 不存在,值 nil 被返回,并且不执行其他动作。 如果 source 和 destination 相同,则列表中的表尾元素被移动到表头,并返回该元素,可以把这种特殊情况视作列表的旋转(rotation)操作。
func (*Client) RPush ¶
RPush 将一个或多个值 value 插入到列表 key 的表尾(最右边)。 如果有多个 value 值,那么各个 value 值按从左到右的顺序依次插入到表尾:比如对一个空列表 mylist 执行 RPUSH mylist a b c ,得出的结果列表为 a b c ,等同于执行命令 RPUSH mylist a 、 RPUSH mylist b 、 RPUSH mylist c 。 如果 key 不存在,一个空列表会被创建并执行 RPUSH 操作。 当 key 存在但不是列表类型时,返回一个错误。
func (*Client) RPushX ¶
RPushX 将值 value 插入到列表 key 的表尾,当且仅当 key 存在并且是一个列表。 和 RPUSH 命令相反,当 key 不存在时, RPUSHX 命令什么也不做。
func (*Client) Rename ¶
Rename 将 key 改名为 newkey 。 当 key 和 newkey 相同,或者 key 不存在时,返回一个错误。 当 newkey 已经存在时, RENAME 命令将覆盖旧值。
func (*Client) Restore ¶
func (r *Client) Restore(ctx context.Context, key any, ttl time.Duration, value string) (val string, err error)
Restore 反序列化给定的序列化值,并将它和给定的 key 关联。 参数 ttl 以毫秒为单位为 key 设置生存时间;如果 ttl 为 0 ,那么不设置生存时间。 RESTORE 在执行反序列化之前会先对序列化值的 RDB 版本和数据校验和进行检查,如果 RDB 版本不相同或者数据不完整的话,那么 RESTORE 会拒绝进行反序列化,并返回一个错误。
func (*Client) RestoreReplace ¶
func (r *Client) RestoreReplace(ctx context.Context, key any, ttl time.Duration, value string) (val string, err error)
RestoreReplace -> Restore
func (*Client) SAdd ¶
SAdd 将一个或多个 member 元素加入到集合 key 当中,已经存在于集合的 member 元素将被忽略。 假如 key 不存在,则创建一个只包含 member 元素作成员的集合。 当 key 不是集合类型时,返回一个错误。
func (*Client) SDiffStore ¶
func (r *Client) SDiffStore(ctx context.Context, destination any, keys ...any) (val int64, err error)

func (*Client) SMembersMap ¶
SMembersMap -> SMembers
func (*Client) SMove ¶
func (r *Client) SMove(ctx context.Context, source, destination any, member any) (val bool, err error)
SMove 将 member 元素从 source 集合移动到 destination 集合。 SMOVE 是原子性操作。 如果 source 集合不存在或不包含指定的 member 元素,则 SMOVE 命令不执行任何操作,仅返回 0 。否则, member 元素从 source 集合中被移除,并添加到 destination 集合中去。 当 destination 集合已经包含 member 元素时, SMOVE 命令只是简单地将 source 集合中的 member 元素删除。 当 source 或 destination 不是集合类型时,返回一个错误。
func (*Client) SRandMember ¶
SRandMember 如果命令执行时,只提供了 key 参数,那么返回集合中的一个随机元素。 从 Redis 2.6 版本开始, SRANDMEMBER 命令接受可选的 count 参数: 如果 count 为正数,且小于集合基数,那么命令返回一个包含 count 个元素的数组,数组中的元素各不相同。如果 count 大于等于集合基数,那么返回整个集合。 如果 count 为负数,那么命令返回一个数组,数组中的元素可能会重复出现多次,而数组的长度为 count 的绝对值。 该操作和 SPOP 相似,但 SPOP 将随机元素从集合中移除并返回,而 SRANDMEMBER 则仅仅返回随机元素,而不对集合进行任何改动。

func (*Client) SetBit ¶
func (r *Client) SetBit(ctx context.Context, key any, offset int64, value int) (val int64, err error)
SetBit 对 key 所储存的字符串值,设置或清除指定偏移量上的位(bit)。 位的设置或清除取决于 value 参数,可以是 0 也可以是 1 。 当 key 不存在时,自动生成一个新的字符串值。 字符串会进行伸展(grown)以确保它可以将 value 保存在指定的偏移量上。当字符串值进行伸展时,空白位置以 0 填充。 offset 参数必须大于或等于 0 ,小于 2^32 (bit 映射被限制在 512 MB 之内)。
func (*Client) SetEx ¶ added in v3.2.31
func (r *Client) SetEx(ctx context.Context, key any, value any, expiration time.Duration) (val string, err error)

SetNX 将 key 的值设为 value ,当且仅当 key 不存在。 若给定的 key 已经存在,则 SETNX 不做任何动作。 SETNX 是『SET if Not eXists』(如果不存在,则 SET)的简写。
func (*Client) SetRange ¶
func (r *Client) SetRange(ctx context.Context, key any, offset int64, value string) (val int64, err error)
SetRange 用 value 参数覆写(overwrite)给定 key 所储存的字符串值,从偏移量 offset 开始。 不存在的 key 当作空白字符串处理。
