A golang mgo. (Mongodb) session store for Martini.
Since Martini uses Gorilla this store extends Gorilla to create a sessions store using Mongo.
The code is pretty much unmodified from the original Gorilla code on another project but it was not packaged up so I packaged it up for martini.
##Usage
//You can pass a mongo connection string. This example is connecting to 3 servers
var params = map[string]string{
"secret": "biglongsecrettext",
"mdb": "databasename",
"muri": "mongodb://user:[email protected]:123,ovdb1-server-mongo-1.mgoserver.net:234,ovdb1-server-mongo-2.mgoserver.net:567"
}
//I'm using a global to store the session database but you don't need to
var DBSESS *mgo.Session
func init() {
//middleware
//db handler
m.Use(DB())
//sessions
store := mgosessions.NewMongoStore(DBSESS.DB(params["mdb"]).C("sessions"), []byte(params["secret"]))
m.Use(sessions.Sessions("sessionid", store))
//do a test
//testSessionFlashes(t, store)
}
//
// MongoDb middleware - Returns a martini.Handler
//
func DB() martini.Handler {
//
//global mongo database connection - used for sessions as well
//
var err error
DBSESS, err = mgo.Dial(params["muri"])
if err != nil {
//panic(err)
fmt.Println("MGO Dial: ", err)
}
return func(c martini.Context) {
s := DBSESS.Clone()
c.Map(s.DB(params["mdb"]))
defer s.Close()
c.Next()
}
}##In a function
db would be the database sess would be the mgo sessions store
func PostAuth(req *http.Request, w http.ResponseWriter, db *mgo.Database, sess sessions.Session) (int, []byte) {
set := session.Set("hello")
get := session.Get("hello")
}
