var ErrInvalidStrategy = errors.New("auth: Invalid strategy")

ErrInvalidStrategy is returned by Append/Revoke functions, when passed strategy does not implement Append/Revoke.

Functions

func Append 

func Append(s Strategy, key interface{}, info Info) error

Append new Info to a strategy store. if passed strategy does not implement Append type ErrInvalidStrategy returned, Otherwise, nil.

WARNING: Append function does not guarantee safe concurrency, It's natively depends on strategy store.

func CtxWithUser 

func CtxWithUser(ctx context.Context, info Info) context.Context

CtxWithUser Save user information in context.

func NewTypeError 

func NewTypeError(prefix string, want, got interface{}) error

NewTypeError returns InvalidType error

func RequestWithUser 

func RequestWithUser(info Info, r *http.Request) *http.Request

RequestWithUser Save user information in request context.

func Revoke 

func Revoke(s Strategy, key interface{}) error

Revoke delete Info from strategy store. if passed strategy does not implement Revoke type ErrInvalidStrategy returned, Otherwise, nil.

WARNING: Revoke function does not guarantee safe concurrency, It's natively depends on strategy store.

func SetInfoConstructor 

func SetInfoConstructor(c InfoConstructor)

SetInfoConstructor replace the default InfoConstructor with any function that has the appropriate signature. This allows the developers to create custom user info from their own struct instead of using the DefaultUser that go-guardian expose.

Default is NewDefaultUser

Types

type Cache 

type Cache interface {
	// Load returns key value.
	Load(key interface{}) (interface{}, bool)
	// Store sets the key value.
	Store(key interface{}, value interface{})
	// StoreWithTTL sets the key value with TTL overrides the default.
	StoreWithTTL(key interface{}, value interface{}, ttl time.Duration)
	// Delete deletes the key value.
	Delete(key interface{})
}

Cache type describes the requirements for authentication strategies, that cache the authentication decisions.

func NewDefaultUser(name, id string, groups []string, extensions Extensions) *DefaultUser

NewDefaultUser return new default user

func (*DefaultUser) GetExtensions 

func (d *DefaultUser) GetExtensions() Extensions

GetExtensions return additional information.

func (*DefaultUser) GetGroups 

func (d *DefaultUser) GetGroups() []string

func (*DefaultUser) GetID 

func (d *DefaultUser) GetID() string

GetID returns a unique value identify a particular user

func (*DefaultUser) GetUserName 

func (d *DefaultUser) GetUserName() string

GetUserName returns the name that uniquely identifies this user among all other active users.

func (*DefaultUser) SetExtensions 

func (d *DefaultUser) SetExtensions(exts Extensions)

SetExtensions to contain additional information.

func (*DefaultUser) SetGroups 

func (d *DefaultUser) SetGroups(groups []string)

SetGroups set the names of the groups the user is a member of.

func (*DefaultUser) SetID 

func (d *DefaultUser) SetID(id string)

type Extensions 

type Extensions map[string][]string

Extensions represents additional information to a user.

func (Extensions) Add 

func (exts Extensions) Add(key, value string)

Add adds the key, value pair to the extensions. It appends to any existing values associated with key. The key is case sensitive.

func (Extensions) Del 

func (exts Extensions) Del(key string)

Del deletes the values associated with key.

func (Extensions) Get 

func (exts Extensions) Get(key string) string

Get gets the first value associated with the given key. It is case sensitive; If there are no values associated with the key, Get returns "".

func (Extensions) Has 

func (exts Extensions) Has(key string) bool

Has reports whether extensions has the provided key defined.

func (Extensions) Set 

func (exts Extensions) Set(key, value string)

Set sets the extensions entries associated with key to the single element value. It replaces any existing values associated with key.

func (Extensions) Values 

func (exts Extensions) Values(key string) []string

Values returns all values associated with the given key. It is case sensitive; The returned slice is not a copy.

type Info 

type Info interface {
	// GetUserName returns the name that uniquely identifies this user among all
	// other active users.
	GetUserName() string
	// SetUserName set the name that uniquely identifies this user among all
	// other active users.
	SetUserName(string)
	// GetID returns a unique value identify a particular user.
	GetID() string
	// SetID set a unique value identify a particular user.
	SetID(string)
	// GetGroups returns the names of the groups the user is a member of
	GetGroups() []string
	// SetGroups set the names of the groups the user is a member of.
	SetGroups(groups []string)
	// Extensions can contain any additional information.
	GetExtensions() Extensions
	// SetExtensions to contain additional information.
	SetExtensions(exts Extensions)
}

Info describes a user that has been authenticated to the system.

func NewUserInfo 

func NewUserInfo(name, id string, groups []string, extensions Extensions) Info

NewUserInfo implements InfoConstructor and return Info object. Typically called from strategies to create a new user object when its authenticated.

func User 

func User(r *http.Request) Info

User return user information from request context.

func UserFromCtx 

func UserFromCtx(ctx context.Context) Info

UserFromCtx return user information from context.

If you're unfamiliar with this style, see https://commandcenter.blogspot.com/2014/01/self-referential-functions-and-design.html and https://dave.cheney.net/2014/10/17/functional-options-for-friendly-apis.

type TypeError struct {
	Want string
	Got  string
	// contains filtered or unexported fields
}

TypeError represent invalid type assertion error.

func (TypeError) Error
