Session Management for QOR

It wrapped other libs like SCS, Gorilla Session into a common interface, which will be used for QOR libs and your application.

Basic Usage

import (
    // ""

var SessionManager = session.ManagerInterface

func main() {
    // Use gorilla session as the backend
    engine := sessions.NewCookieStore([]byte("something-very-secret"))
    SessionManager = gorilla.New("_session", engine)
    // Use SCS as the backend
    // engine := memstore.New(0)
    // SessionManager := scs.New(engine)

    mux := http.NewServeMux()
    mux.HandleFunc("/put", putHandler)
    mux.HandleFunc("/get", getHandler)
    // Your routes

    // Wrap your application's handlers or router with session manager's middleware
    http.ListenAndServe(":7000", manager.Middleware(mux))

func putHandler(w http.ResponseWriter, req *http.Request) {
    // Store a key and associated value into session data
    SessionManager.Add(w, req, "key", "value")

func getHandler(w http.ResponseWriter, req *http.Request) {
    // Get saved session data with key
    value := SessionManager.Get(req, "key")
    io.WriteString(w, value)

Session Manager's Interface

type ManagerInterface interface {
    // Add value to session data, if value is not string, will marshal it into JSON encoding and save it into session data.
    Add(w http.ResponseWriter, req *http.Request, key string, value interface{}) error

    // Get value from session data
    Get(req *http.Request, key string) string

    // Pop value from session data
    Pop(w http.ResponseWriter, req *http.Request, key string) string

    // Flash add flash message to session data
    Flash(w http.ResponseWriter, req *http.Request, message Message) error

    // Flashes returns a slice of flash messages from session data
    Flashes(w http.ResponseWriter, req *http.Request) []Message

    // Load get value from session data and unmarshal it into result
    Load(req *http.Request, key string, result interface{}) error

    // PopLoad pop value from session data and unmarshal it into result
    PopLoad(w http.ResponseWriter, req *http.Request, key string, result interface{}) error

    // Middleware returns a new session manager middleware instance.
    Middleware(http.Handler) http.Handler

QOR Integration

We have created a default session manager in package, which is used in some QOR libs like QOR Admin, QOR Auth by default to manage session, flash messages.

It is defined like below:

var SessionManager session.ManagerInterface = gorilla.New("_session", sessions.NewCookieStore([]byte("secret")))

You should change it to your own session storage or use your own secret code.

import (

func main() {
    // Overwrite session manager
    engine := sessions.NewCookieStore([]byte("your-own-secret-code"))
    manager.SessionManager = gorilla.New("_gorilla_session", engine)
