一、redis

go get -u github.com/go-redis/redis

var redisdb *redis.Client

redisdb = redis.New(&redis.Options{

Addr:"127.0.0.1:6379",

Password:"",

DB:0,

})

redisdb.Set("test:name","value",time.Minute * 10) 十分钟失效 过期时间设置为0 是永不过期

val,err:=redisdb.Get("key").Result()

println(val)

二、session

go get github.com/gin-contrib/sessions

import "github.com/gin-contrib/sessions"

2.1、基于redis使用

在main.go 中

import(

"github.com/gin-contrib/sessions"

"github.com/gin-contrib/sessions/redis"

)

engine:=gin.Default()

strore,_:=redis.NewStore(10,"tpc","localhost:6379","",[]byte("secret"))

engine.Use(sessions.Sessions("mysession",store))

engine.GET("/path",func(context *gin.Context){

session:=sessions.Default(context)

//保存

num:=16

session.Set("count",num)

session.Save()

//读取

num=session.Get("count")

})

json.Marshal(member) //将 member 对象序列化

session.Set("user_id",json.Marshal(member))

反序列化

var member Member

sess:=session.Get("user_id")

json.Unmarshal(sess.([]byte),&member)

三、上传图片

file,err:=context.FormFile("file")

filename:="./uploadPath/"+strcov.Format(time.Now().Unix(),10)+file.Filename

err:=context.SaveUploadFile(file,filename)

四、cookie

//设置cookie

context.SetCookie("cookie_key","val",10*60,"localhost",true,true)

获取cookie

cookie,err:=context.Request.Cookie("cookie_key")

const CookieName="cookie_user"

const CookieTiimeLen=10*60

func CookieAuth(context *gin.Context) (*http.Cookie,error){

cookie,err:=context.Request.Cookie(CookieName)

if err==nil{

context.SetCookie(cookie.Name,cookie.Value,cookie.MaxAge,cookie.Path,cookie.Domain,cookie.Secure,cookie.HttpOnly)

return cookie,nil

}else{

return nil,err

}

}
