Gin middleware for session management with multi-backend support:
Usage
Start using it
Download and install it:
go get github.com/wyy-go/wsession
Import it in your code:
import "github.com/wyy-go/wsession"
Basic Examples
single session
package main
import (
"github.com/wyy-go/wsession"
"github.com/wyy-go/wsession/cookie"
"github.com/gin-gonic/gin"
)
func main() {
r := gin.Default()
store := cookie.NewStore([]byte("secret"))
r.Use(wsession.New("mysession", store))
r.GET("/hello", func(c *gin.Context) {
session := wsession.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/wyy-go/wsession"
"github.com/wyy-go/wsession/cookie"
"github.com/gin-gonic/gin"
)
func main() {
r := gin.Default()
store := cookie.NewStore([]byte("secret"))
sessionNames := []string{"a", "b"}
r.Use(wsession.NewMany(sessionNames, store))
r.GET("/hello", func(c *gin.Context) {
sessionA := wsession.DefaultMany(c, "a")
sessionB := wsession.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")
}
Backend Examples
cookie-based
package main
import (
"github.com/wyy-go/wsession"
"github.com/wyy-go/wsession/cookie"
"github.com/gin-gonic/gin"
)
func main() {
r := gin.Default()
store := cookie.NewStore([]byte("secret"))
r.Use(wsession.New("mysession", store))
r.GET("/incr", func(c *gin.Context) {
session := wsession.Default(c)
var count int
v := session.Get("count")
if v == nil {
count = 0
} else {
count = v.(int)
count++
}
session.Set("count", count)
session.Save()
c.JSON(200, gin.H{"count": count})
})
r.Run(":8000")
}
Redis
package main
import (
"github.com/wyy-go/wsession"
"github.com/wyy-go/wsession/redis"
"github.com/gin-gonic/gin"
)
func main() {
r := gin.Default()
store, _ := redis.NewStore(10, "tcp", "localhost:6379", "", []byte("secret"))
r.Use(wsession.New("mysession", store))
r.GET("/incr", func(c *gin.Context) {
session := wsession.Default(c)
var count int
v := session.Get("count")
if v == nil {
count = 0
} else {
count = v.(int)
count++
}
session.Set("count", count)
session.Save()
c.JSON(200, gin.H{"count": count})
})
r.Run(":8000")
}
memstore
package main
import (
"github.com/wyy-go/wsession"
"github.com/wyy-go/wsession/memstore"
"github.com/gin-gonic/gin"
)
func main() {
r := gin.Default()
store := memstore.NewStore([]byte("secret"))
r.Use(wsession.New("mysession", store))
r.GET("/incr", func(c *gin.Context) {
session := wsession.Default(c)
var count int
v := session.Get("count")
if v == nil {
count = 0
} else {
count = v.(int)
count++
}
session.Set("count", count)
session.Save()
c.JSON(200, gin.H{"count": count})
})
r.Run(":8000")
}
