Types

type Client

type Client struct {
	// contains filtered or unexported fields
}

Client 返回redis的客户端

func NewClient

func NewClient(addrs []string, password string) (*Client, error)

NewClient 新建一个redis的客户端，addr为集群地址，如果只有一个默认单机

func (*Client) Add

func (c *Client) Add(ctx context.Context, k string, v []byte, ttl int64) error

Add 如果key不存在则放入value，如果存在返回ErrKeyExsit

func (*Client) Append

func (c *Client) Append(ctx context.Context, k string, v []byte) error

Append 将value添加到set之中

func (*Client) Close

func (c *Client) Close() error

Close 关闭与redis的连接

func (*Client) Del

func (c *Client) Del(ctx context.Context, k string) error

Del 删除一个key的value

func (*Client) Discard

func (c *Client) Discard() error

Discard 将管道中的操作列表清空，用于取消事务

func (*Client) Exec

func (c *Client) Exec() ([]interface{}, error)

Exec 执行管道中缓存的操作，用于提交事务

func (*Client) Expire

func (c *Client) Expire(ctx context.Context, k string, ttl int64) error

Expire 给key设置过期时间，单位（s）

func (*Client) Get

func (c *Client) Get(ctx context.Context, s string) ([]byte, error)

Get 按key获取value，如果不存在返回ErrCacheMiss

func (*Client) Incr

func (c *Client) Incr(ctx context.Context, k string) (int64, error)

Incr 将key的value+1

func (*Client) IsMember

func (c *Client) IsMember(ctx context.Context, k string, v []byte) (bool, error)

IsMember value是否是key的set中的值

func (*Client) LLen

func (c *Client) LLen(ctx context.Context, k string) (int64, error)

LLen 查看key的list的长度

func (*Client) LPop

func (c *Client) LPop(ctx context.Context, k string) ([]byte, error)

LPop 在list中移除最左的数据

func (*Client) Pipeline

func (c *Client) Pipeline() *Client

Pipeline 返回一个管道，用于开启事务

func (*Client) Put

func (c *Client) Put(ctx context.Context, k string, v []byte, ttl int64) error

Put 将数据放入缓存，ttl为过期时间 单位（s）

func (*Client) RPush

func (c *Client) RPush(ctx context.Context, k string, v []byte) error

RPush 将数据push到key的list中

func (*Client) SMembers

func (c *Client) SMembers(ctx context.Context, k string) ([]string, error)

SMembers 列出set的所有的值

func (*Client) SRem

func (c *Client) SRem(ctx context.Context, k string, v []byte) error

SRem 在set中移除特定的value
