本文介绍了如何使用Go的go-redis库进行Redis操作，包括创建普通模式、主从模式和哨兵模式的客户端，重点讲解了连接（Conn）、Pipeline和发布订阅（PubSub）的使用方法，并提供了相关示例代码。

内容：

一 . 客户端Client（普通模式，主从模式，哨兵模式）

二. conn连接(连接， pipline，发布订阅等)

三. 示例程序(连接， pipline，发布订阅等)

客户端

Client 普通模式的客户端

go redis依据用途提供了多种客户端创建的函数，如下：

func NewClient(opt *Options) *Client
func NewFailoverClient(failoverOpt *FailoverOptions) *Client
func (c *Client) Context() context.Context
func (c *Client) Do(args ...interface{}) *Cmd
func (c *Client) DoContext(ctx context.Context, args ...interface{}) *Cmd
func (c *Client) Options() *Options
func (c *Client) PSubscribe(channels ...string) *PubSub
func (c *Client) Pipeline() Pipeliner
func (c *Client) Pipelined(fn func(Pipeliner) error) ([]Cmder, error)
func (c *Client) PoolStats() *PoolStats
func (c *Client) Process(cmd Cmder) error
func (c *Client) ProcessContext(ctx context.Context, cmd Cmder) error
func (c *Client) SetLimiter(l Limiter) *Client
func (c *Client) Subscribe(channels ...string) *PubSub
func (c *Client) TxPipeline() Pipeliner
func (c *Client) TxPipelined(fn func(Pipeliner) error) ([]Cmder, error)
func (c *Client) Watch(fn func(*Tx) error, keys ...string) error
func (c *Client) WithContext(ctx context.Context) *Client

NewClient 创建一个普通连接

NewFailoverClient 具有故障检测以及故障转移的client

PSubscribe / Subscribe 发布订阅模式的client

Pipeline 启用pipline管道模式的client

PoolStats 连接池状态

Close 关闭连接

集群模式的ClusterClient

func NewClusterClient(opt *ClusterOptions) *ClusterClient
func (c *ClusterClient) Close() error
func (c *ClusterClient) Context() context.Context
func (c *ClusterClient) DBSize() *IntCmd
func (c *ClusterClient) Do(args ...interface{}) *Cmd
func (c *ClusterClient) DoContext(ctx context.Context, args ...interface{}) *Cmd
func (c *ClusterClient) ForEachMaster(fn func(client *Client) error) error
func (c *ClusterClient) ForEachNode(fn func(client *Client) error) error
func (c *ClusterClient) ForEachSlave(fn func(client *Client) error) error
func (c *ClusterClient) Options() *ClusterOptions
func (c *ClusterClient) PSubscribe(channels ...string) *PubSub
func (c *ClusterClient) Pipeline() Pipeliner
func (c *ClusterClient) Pipelined(fn func(Pipeliner) error) ([]Cmder, error)
func (c *ClusterClient) PoolStats() *PoolStats
func (c *ClusterClient) Process(cmd Cmder) error
func (c *ClusterClient) ProcessContext(ctx context.Context, cmd Cmder) error
func (c *ClusterClient) ReloadState() error
func (c *ClusterClient) Subscribe(channels ...string) *PubSub
func (c *ClusterClient) TxPipeline() Pipeliner
func (c *ClusterClient) TxPipelined(fn func(Pipeliner) error) ([]Cmder, error)
func (c *ClusterClient) Watch(fn func(*Tx
