Introduction of github.com/gomodule/redigo/redis

Initialize redis connection func InitRedis () {password: = beego.AppConfig.String ("Redis::Password") redisHost: = beego.AppConfig.String ("Redis::Address") dataBase,_: = beego.AppConfig.Int ("Redis::DataBase") rc: = & redis.Pool {/ / maximum idle link MaxIdle: 10 / / maximum active link MaxActive: 10, / / maximum idle link waiting time IdleTimeout: 5 * time.Second, Dial: func () (redis.Conn, error) {r, err: = redis.Dial ("tcp", redisHost) ) if err! = nil {return nil, err} / / aws redis has no password if password! = "" {if _, err: = r.Do ("AUTH", password) Err! = nil {r.Close () return nil, err}} r.Do ("SELECT", dataBase) return r, nil} } redisConn = rc.Get ()} commonly used get set del examples func SetKV (key string,value interface {}, time int) (err error) {_, err = redisConn.Do ("SET", key, value, "EX", time) if err! = nil {beego.Error ("set key:", key, ", value:", value Err)} return} func GetKV (key string) (value interface {}) {value, err: = redisConn.Do ("GET", key) if err! = nil {beego.Error ("GetKV key:", key,err)} return value} func DelKey (key string) (err error) {_, err = redisConn.Do ("DEL") Key) if err! = nil {beego.Error ("DelKey key:", key,err)} return} use lua script example / * * counter * / func Counter (key string,time int, limitTimes int) int {script: = "local num = redis.call ('incr') KEYS [1])\ n "+" if tonumber (num) = = 1 then\ n "+"\ t redis.call ('expire', KEYS [1]) ARGV [1])\ n "+"\ t return 1\ n "+" elseif tonumber (num) > tonumber (ARGV [2]) then\ n "+"\ t return 0\ n "+ "else\ n" + "\ t return 1\ n" + "end\ n" / / result: = invokeLua (1 Lua,key,time,limitTimes) luaScript: = redis.NewScript (1Powerscript) result,err: = luaScript.Do (redisConn,key,time,limitTimes) if err! = nil {beego.Error ("invokeLua script:", script,err)} return int (result. (int64))} so far I believe you have a deeper understanding of "the use of redis in golang", so you might as well do it in practice.
