Example
Here is a simple example using BoltStore. You can see other examples on the BoltStore's GoDoc page.
package main
import (
"fmt"
"net/http"
"github.com/boltdb/bolt"
"github.com/admpub/sessions"
"github.com/admpub/boltstore/reaper"
"github.com/admpub/boltstore/store"
)
var db *bolt.DB
func handler(w http.ResponseWriter, r *http.Request) {
// Create a store.
str, err := store.New(db, store.Config{}, []byte("secret-key"))
if err != nil {
http.Error(w, err.Error(), http.StatusInternalServerError)
}
// Get a session.
session, err := str.Get(r, "session-key")
if err != nil {
http.Error(w, err.Error(), http.StatusInternalServerError)
}
// Add a value on the session.
session.Values["foo"] = "bar"
// Save the session.
if err := sessions.Save(r, w); err != nil {
http.Error(w, err.Error(), http.StatusInternalServerError)
}
fmt.Fprintf(w, "Hello BoltStore")
}
func main() {
var err error
// Open a Bolt database.
db, err = bolt.Open("./sessions.db", 0666, nil)
if err != nil {
panic(err)
}
defer db.Close()
// Invoke a reaper which checks and removes expired sessions periodically.
defer reaper.Quit(reaper.Run(db, reaper.Options{}))
http.HandleFunc("/", handler)
http.ListenAndServe(":8080", nil)
}
