sessions

Build Status codecov Go Report Card GoDoc Join the chat at https://gitter.im/gin-gonic/gin

Gin middleware for session management with multi-backend support:

Usage

Start using it

Download and install it:

$ go get github.com/gin-contrib/sessions

Import it in your code:

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

Basic Examples

single session

package main

import (
	"github.com/gin-contrib/sessions"
	"github.com/gin-contrib/sessions/cookie"
	"github.com/gin-gonic/gin"
)

func main() {
	r := gin.Default()
	store := cookie.NewStore([]byte("secret"))
	r.Use(sessions.Sessions("mysession", store))

	r.GET("/hello", func(c *gin.Context) {
		session := sessions.Default(c)

		if session.Get("hello") != "world" {
			session.Set("hello", "world")
			session.Save()
		}

		c.JSON(200, gin.H{"hello": session.Get("hello")})
	})
	r.Run(":8000")
}

multiple sessions

package main

import (
	"github.com/gin-contrib/sessions"
	"github.com/gin-contrib/sessions/cookie"
	"github.com/gin-gonic/gin"
)

func main() {
	r := gin.Default()
	store := cookie.NewStore([]byte("secret"))
	sessionNames := []string{"a", "b"}
	r.Use(sessions.SessionsMany(sessionNames, store))

	r.GET("/hello", func(c *gin.Context) {
		sessionA := sessions.DefaultMany(c, "a")
		sessionB := sessions.DefaultMany(c, "b")

		if sessionA.Get("hello") != "world!" {
			sessionA.Set("hello", "world!")
			sessionA.Save()
		}

		if sessionB.Get("hello") != "world?" {
			sessionB.Set("hello", "world?")
			sessionB.Save()
		}

		c.JSON(200, gin.H{
			"a": sessionA.Get("hello"),
			"b": sessionB.Get("hello"),
		})
	})
	r.Run(":8000")
}
