Functions

func SetKeyPrefix

func SetKeyPrefix(s Store, prefix string) error

SetKeyPrefix sets the key prefix in the redis database.

Types

type GobSerializer

type GobSerializer struct{}

GobSerializer uses gob package to encode the sessions map

func (GobSerializer) Deserialize

func (s GobSerializer) Deserialize(d []byte, ss *sessions.Session) error

Deserialize back to map[interface{}]interface{}

func (GobSerializer) Serialize

func (s GobSerializer) Serialize(ss *sessions.Session) ([]byte, error)

Serialize using gob

type JSONSerializer

type JSONSerializer struct{}

JSONSerializer encode the sessions map to JSON.

func (JSONSerializer) Deserialize

func (s JSONSerializer) Deserialize(d []byte, ss *sessions.Session) error

Deserialize back to map[string]interface{}

func (JSONSerializer) Serialize

func (s JSONSerializer) Serialize(ss *sessions.Session) ([]byte, error)

Serialize to JSON. Will err if there are unmarshalable key values

type RediStore

type RediStore struct {
	Pool          *redis.Pool
	Options       *sessions.Options // default configuration
	DefaultMaxAge int               // default Redis TTL for a MaxAge == 0 sessions
	// contains filtered or unexported fields
}

RediStore stores sessions in a redis backend.

func GetRedisStore

func GetRedisStore(s Store) (err error, rediStore *RediStore)

GetRedisStore get the actual woking store.

Ref: https://godoc.org/github.com/boj/redistore#RediStore

func NewRediStore

func NewRediStore(size int, network, address, password string) (*RediStore, error)

NewRediStore returns a new RediStore. size: maximum number of idle connections.

func NewRediStoreWithDB

func NewRediStoreWithDB(size int, network, address, password, DB string) (*RediStore, error)

NewRediStoreWithDB - like NewRedisStore but accepts `DB` parameter to select redis DB instead of using the default one ("0")

func NewRediStoreWithPool

func NewRediStoreWithPool(pool *redis.Pool) (*RediStore, error)

NewRediStoreWithPool instantiates a RediStore with a *redis.Pool passed in.

func (*RediStore) Close

func (s *RediStore) Close() error

Close closes the underlying *redis.Pool

func (*RediStore) Delete

func (s *RediStore) Delete(r *http.Request, w http.ResponseWriter, session *sessions.Session) error

Delete removes the sessions from redis, and sets the cookie to expire.

WARNING: This method should be considered deprecated since it is not exposed via the gorilla/sessions interface. Set sessions.Options.MaxAge = -1 and call Save instead. - July 18th, 2013

func (*RediStore) Get

func (s *RediStore) Get(r *http.Request, name string) (*sessions.Session, error)

Get returns a sessions for the given name after adding it to the registry.

See gorilla/sessions FilesystemStore.Get().

func (*RediStore) New

func (s *RediStore) New(r *http.Request, name string) (*sessions.Session, error)

New returns a sessions for the given name without adding it to the registry.

See gorilla/sessions FilesystemStore.New().

func (*RediStore) Save

func (s *RediStore) Save(r *http.Request, w http.ResponseWriter, session *sessions.Session) error

Save adds a single sessions to the response.

func (*RediStore) SetKeyPrefix

func (s *RediStore) SetKeyPrefix(p string)

SetKeyPrefix set the prefix

func (*RediStore) SetMaxAge

func (s *RediStore) SetMaxAge(v int)

SetMaxAge restricts the maximum age, in seconds, of the sessions record both in database and a browser. This is to change sessions storage configuration. If you want just to remove sessions use your sessions `s` object and change it's `Options.MaxAge` to -1, as specified in

http://godoc.org/github.com/gorilla/sessions#Options

Default is the one provided by this package value - `sessionExpire`. Set it to 0 for no restriction. Because we use `MaxAge` also in SecureCookie crypting algorithm you should use this function to change `MaxAge` value.

func (*RediStore) SetMaxLength

func (s *RediStore) SetMaxLength(l int)

SetMaxLength sets RediStore.maxLength if the `l` argument is greater or equal 0 maxLength restricts the maximum length of new sessions to l. If l is 0 there is no limit to the size of a sessions, use with caution. The default for a new RediStore is 4096. Redis allows for max. value sizes of up to 512MB (http://redis.io/topics/data-types) Default: 4096,

func (*RediStore) SetSerializer

func (s *RediStore) SetSerializer(ss SessionSerializer)

SetSerializer sets the serializer

type SessionSerializer

type SessionSerializer interface {
	Deserialize(d []byte, ss *sessions.Session) error
	Serialize(ss *sessions.Session) ([]byte, error)
}

SessionSerializer provides an interface hook for alternative serializers

type Store

type Store interface {
	sessions.Store
}

func NewStore

func NewStore(size int, network, address, password string) (Store, error)

func NewStoreWithDB

func NewStoreWithDB(size int, network, address, password, DB string) (Store, error)

NewStoreWithDB - like NewStore but accepts `DB` parameter to select redis DB instead of using the default one ("0")

Ref: https://godoc.org/github.com/boj/redistore#NewRediStoreWithDB

func NewStoreWithPool

func NewStoreWithPool(pool *redis.Pool) (Store, error)

NewStoreWithPool instantiates a RediStore with a *redis.Pool passed in.
