Types

type FromMemory

type FromMemory struct {
	Sessions map[string]Session
	// contains filtered or unexported fields
}

session来自内存

func (*FromMemory) DestroySession

func (fm *FromMemory) DestroySession(Sid string) error

func (*FromMemory) GCSession

func (fm *FromMemory) GCSession()

func (*FromMemory) GetSession

func (fm *FromMemory) GetSession(Sid string) Session

func (*FromMemory) In

func (m *FromMemory) In(i []byte)

func (*FromMemory) InitSession

func (fm *FromMemory) InitSession(Sid string, MaxAge int64) (Session, error)

func (*FromMemory) Out

func (m *FromMemory) Out() []byte

type Session

type Session interface {
	Set(key, value interface{})
	Get(key interface{}) interface{}
	Remove(key interface{}) error
	GetId() string
	Update()
}

-------------session_implements----------------- Session操作接口，不同存储方式的Sesion操作不同，实现也不同

type SessionFromMemory

type SessionFromMemory struct {
	Sid string

	LastAccessedTime time.Time
	MaxAge           int64
	Data             map[interface{}]interface{}
	// contains filtered or unexported fields
}

session实现

func (*SessionFromMemory) Get

func (si *SessionFromMemory) Get(key interface{}) interface{}

func (*SessionFromMemory) GetId

func (si *SessionFromMemory) GetId() string

func (*SessionFromMemory) Remove

func (si *SessionFromMemory) Remove(key interface{}) error

func (*SessionFromMemory) Set

func (si *SessionFromMemory) Set(key, value interface{})

func (*SessionFromMemory) Update

func (si *SessionFromMemory) Update()

type SessionManager

type SessionManager struct {
	// contains filtered or unexported fields
}

--------------session_manager---------------------- 管理Session,实际操作cookie，Storage 由于该结构体是整个应用级别的，写、修改都需要枷锁

func NewSessionManager

func NewSessionManager() *SessionManager

实例化一个session管理器

func (*SessionManager) BeginSession

func (m *SessionManager) BeginSession(w http.ResponseWriter, r *http.Request) Session

先判断当前请求的cookie中是否存在有效的session,存在返回，不存在创建

func (*SessionManager) CookieIsExists

func (m *SessionManager) CookieIsExists(r *http.Request) bool

func (*SessionManager) Destroy

func (m *SessionManager) Destroy(w http.ResponseWriter, r *http.Request)

手动销毁session，同时删除cookie

func (*SessionManager) GC

func (m *SessionManager) GC()

func (*SessionManager) GetCookieN

func (m *SessionManager) GetCookieN() string

func (*SessionManager) GetSessionById

func (m *SessionManager) GetSessionById(sid string) Session

通过ID获取session

func (*SessionManager) In

func (m *SessionManager) In(i []byte)

func (*SessionManager) Out

func (m *SessionManager) Out() []byte

func (*SessionManager) SetMaxAge

func (m *SessionManager) SetMaxAge(t int64)

func (*SessionManager) SetSessionFrom

func (m *SessionManager) SetSessionFrom(storage Storage)

func (*SessionManager) Update

func (m *SessionManager) Update(w http.ResponseWriter, r *http.Request)

更新超时

type Storage

type Storage interface {
	//初始化一个session，id根据需要生成后传入
	InitSession(sid string, maxAge int64) (Session, error)
	//根据sid，获得当前session
	GetSession(sid string) Session
	//销毁session
	DestroySession(sid string) error
	//回收
	GCSession()
	In([]byte)
	Out() []byte
}

--------------session_from--------------------------- session存储方式接口，可以存储在内存，数据库或者文件 分别实现该接口即可 如存入数据库的CRUD操作
