Types

type Config

type Config struct {
	// The domain to assign cookies to.
	Domain string

	Env trails.Environment

	// The number of seconds a session is valid.
	MaxAge int

	// The name sessions are stored under.
	// Also used as the name of the cookie when WithCookie is used.
	SessionName string

	// Hex-encoded key
	AuthKey string

	// Hex-encoded key
	EncryptKey string
}

A Config provides values required for constructing a session.Service.

type Flash

type Flash struct {
	Type string `json:"type"`
	Msg  string `json:"message"`
}

A Flash is a structured message set in a session.

func (Flash) GetClass

func (f Flash) GetClass() string

type Service

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

A Service wraps a gorilla.Store to manage constructing a new one and accessing the sessions contained in it.

Service implements SessionStorer.

func NewStoreService

func NewStoreService(cfg Config) (Service, error)

NewStoreService initiates a data store for user web sessions with the provided config.

func (Service) GetSession

func (s Service) GetSession(r *http.Request) (Session, error)

GetSession retrieves the Session for the *http.Request, or creates a brand new one.

type ServiceOpt

type ServiceOpt func(*Service) error

A ServiceOpt configures the provided *Service, returning an error if unable to.

type Session

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

A Session provides all functionality for managing a fully featured session.

Its functionality is implemented by lightly wrapping a gorilla.Session.

func (Session) ClearFlashes

func (s Session) ClearFlashes(w http.ResponseWriter, r *http.Request)

ClearFlashes removes all Flashes from the Session.

func (Session) Delete

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

Delete removes a session by making the MaxAge negative.

func (Session) DeregisterUser

func (s Session) DeregisterUser(w http.ResponseWriter, r *http.Request) error

DeregisterUser removes the User from the session.

func (Session) Flashes

func (s Session) Flashes(w http.ResponseWriter, r *http.Request) []Flash

Flashes retrieves []Flash stored in the session.

func (Session) Get

func (s Session) Get(key any) any

Get retrieves a value from the session according to the key passed in.

func (Session) RegisterUser

func (s Session) RegisterUser(w http.ResponseWriter, r *http.Request, ID uint) error

RegisterUserSession stores the user's ID in the session.

func (Session) ResetExpiry

func (s Session) ResetExpiry(w http.ResponseWriter, r *http.Request) error

ResetExpiry resets the expiration of the session by saving it.

func (Session) Save

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

Save wraps gorilla.Session.Save, saving the session in the request.

func (Session) Set

func (s Session) Set(w http.ResponseWriter, r *http.Request, key trails.Key, val any) error

Set stores a value according to the key passed in on the session.

func (Session) SetFlash

func (s Session) SetFlash(w http.ResponseWriter, r *http.Request, flash Flash) error

SetFlash stores the passed in Flash in the session.

func (Session) UserID

func (s Session) UserID() (uint, error)

UserID gets the user ID out of the session. A user ID should be present in a session if the user is successfully authenticated. If no user ID can be found, this ErrNoUser is returned. This ought to only happen when a user is going through an authentication workflow or hitting unauthenticated pages.

If the value returned from the session is not a uint, ErrNotValid is returned and represents a programming error.

type SessionStorer

type SessionStorer interface {
	GetSession(r *http.Request) (Session, error)
}

The SessionStorer defines methods for interacting with a Sessionable for the given *http.Request.

type Stub

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

func NewStub

func NewStub(loggedIn bool) *Stub

func (Stub) Get

func (s Stub) Get(r *http.Request, name string) (*gorilla.Session, error)

func (*Stub) GetSession

func (s *Stub) GetSession(r *http.Request) (Session, error)

func (Stub) New

func (s Stub) New(r *http.Request, name string) (*gorilla.Session, error)

func (Stub) Save

func (s Stub) Save(r *http.Request, w http.ResponseWriter, sess *gorilla.Session) error
