Gorilla's Session Store Implementation for ClusterSQL - Server Fram of MySQLs

Dependency

EnumApps/clustersql (https://github.com/EnumApps/clustersql) ;

EnumApps/aerror (https://github.com/EnumApps/aerror) - for error tracing;

Run

  go get github.com/go-sql-driver/mysql 
  go get github.com/EnumApps/clustersqlstore
  go get github.com/EnumApps/aerror

Installation

Run

  go get github.com/EnumApps/clustersqlstore

from command line. Gets installed in $GOPATH

Database Config

create table with following SQL CREATE TABLE session_cluster ( id char(40) NOT NULL COMMENT '2006-01-02T15:04:05.999999999Z07:00+(00000-99999)', data longblob NOT NULL, expire_on datetime NOT NULL, modify_at timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP ) ENGINE=InnoDB DEFAULT CHARSET=ascii;

clean up session with following SQL

  CREATE EVENT AutoDeleteOldSession
  ON SCHEDULE EVERY 1 HOUR
  ON COMPLETION PRESERVE
  DISABLE ON SLAVE
  DO DELETE LOW_PRIORITY FROM <database>.session_cluster WHERE `expire_on` < DATE_SUB(NOW(), INTERVAL 1 HOUR)

Usage

NewClusterSQLStore takes the following paramaters

driverName  - the name of pre-registered cluster drvier, see EnumApps/clustersql (https://github.com/EnumApps/clustersql) for detail
path        - path for Set-Cookie header
maxAge      - maxAge for session
codecs

Internally, clustersqlstore uses this ClusterSQL driver (not the original one; Since you may using another connection for your major data, this patched version allow multi drivers, each have a custom name).

e.g.,

  package main

  import (
    "fmt"
    "github.com/EnumApps/clustersqlstore"
    "net/http"
  )

  var store, _ = clustersqlstore.NewClusterSQLStore(<drivername>, "/", 3600, []byte("<SecretKey>"))
  defer store.Close()

  func sessTest(w http.ResponseWriter, r *http.Request) {
    session, err := store.Get(r, "foobar")
    session.Values["bar"] = "baz"
    session.Values["baz"] = "foo"
    err = session.Save(r, w)
    fmt.Printf("%#v\n", session)
    fmt.Println(err)
  }

func main() {
	http.HandleFunc("/", sessTest)
	http.ListenAndServe(":8080", nil)
}
