README

fasthttpsession is a fast and powerful session package for fasthttp servers

中文文档

Description

fasthttpsession is a session manager for Go. It only supports fasthttp, currently support providers:

• file
• memcache
• memory
• mysql
• postgres
• redis
• sqlite3

Features

• Focus on the design of the code architecture and expansion.
• Provide full session storage.
• Convenient switching of session storage.
• Customizable data serialization.
• Implement concurrent map(ccmap.go) to improve performance.

Install

The only requirement is the Go Programming Language, at least v1.7

$ go get -u github.com/phachon/fasthttpsession
$ go get ./...

Used

Quick Start

// fasthttpsession use memory provider

import (
	"github.com/mikhailzhukov/fasthttpsession"
	"github.com/mikhailzhukov/fasthttpsession/memory"
	"github.com/valyala/fasthttp"
	"log"
	"os"
)

// default config
var session = fasthttpsession.NewSession(fasthttpsession.NewDefaultConfig())

func main()  {
	// you must set up provider before use
	err := session.SetProvider("memory", &memory.Config{})
	if err != nil {
		log.Println(err.Error())
		os.Exit(1)
	}
	addr := ":8086"
	log.Println("fasthttpsession example server listen: "+addr)
	
	// fasthttp start listen serve
	err = fasthttp.ListenAndServe(addr, requestHandle)
	if err != nil {
		log.Println("listen server error :"+err.Error())
	}
}

// request handler
func requestHandle(ctx *fasthttp.RequestCtx) {
	// start session
	sessionStore, err := session.Start(ctx)
	if err != nil {
		ctx.SetBodyString(err.Error())
		return
	}
	// must defer sessionStore.save(ctx)
	defer sessionStore.Save(ctx)

	sessionStore.Set("name", "fasthttpsession")

	ctx.SetBodyString(fmt.Sprintf("fasthttpsession setted key name= %s ok", sessionStore.Get("name").(string)))
}

Custom configuration

If you don't want to use the default configuration, please use the following struct custom.

type Config struct {

	// cookie name
	CookieName string
	
	// cookie domain
	Domain string
	
	// If you want to delete the cookie when the browser closes, set it to -1.
	//
	//  0 means no expire, (24 years)
	// -1 means when browser closes
	// >0 is the time.Duration which the session cookies should expire.
	Expires time.Duration
	
	// gc life time(s)
	GCLifetime int64
	
	// session life time(s)
	SessionLifetime int64
	
	// set whether to pass this bar cookie only through HTTPS
	Secure bool
	
	// sessionId is in url query
	SessionIdInURLQuery bool
	
	// sessionName in url query
	SessionNameInUrlQuery string
	
	// sessionId is in http header
	SessionIdInHttpHeader bool
	
	// sessionName in http header
	SessionNameInHttpHeader string
	
	// SessionIdGeneratorFunc should returns a random session id.
	SessionIdGeneratorFunc func() string
	
	// Encode the cookie value if not nil.
	EncodeFunc func(cookieValue string) (string, error)
	
	// Decode the cookie value if not nil.
	DecodeFunc func(cookieValue string) (string, error)
}

Different session provider config, please look at the Config.go the provider name directory.
