package main
import (
"github.com/gin-gonic/contrib/sessions"
"github.com/gin-gonic/gin"
)
func main() {
r := gin.Default()
store := sessions.NewCookieStore([]byte("secret"))
r.Use(sessions.Sessions("mysession", store))
r.GET("/incr", func(c *gin.Context) {
session := sessions.Default(c)
var count int
v := session.Get("count")
if v == nil {
count = 0
} else {
count = v.(int)
count += 1
}
session.Set("count", count)
session.Save()
c.JSON(200, gin.H{"count": count})
})
r.Run(":8000")
}
```
#### Redis
```go
package main
import (
"github.com/gin-gonic/contrib/sessions"
"github.com/gin-gonic/gin"
)
func main() {
r := gin.Default()
store, _ := sessions.NewRedisStore(10, "tcp", "localhost:6379", "", []byte("secret"))
r.Use(sessions.Sessions("session", store))
r.GET("/incr", func(c *gin.Context) {
session := sessions.Default(c)
var count int
v := session.Get("count")
if v == nil {
count = 0
} else {
count = v.(int)
count += 1
}
session.Set("count", count)
session.Save()
c.JSON(200, gin.H{"count": count})
})
r.Run(":8000")
