Constants ¶
const AccessTokenContextKey = "fire.auth.access_token"
AccessTokenContextKey is the key used to save the access token in a context.

Functions ¶
func Callback ¶
Callback returns a callback that can be used to protect resources by requiring an access token with the provided scopes to be granted.
Note: It requires that the request has already been authorized using the Authorizer middleware of an authenticator.
func DefaultGrantStrategy ¶
func DefaultGrantStrategy(req *GrantRequest) (bool, []string)
DefaultGrantStrategy grants the complete requested scope.
Types ¶
type AccessToken ¶
type AccessToken struct {
fire.Base `json:"-" bson:",inline" fire:"access-tokens:access_tokens"`
Signature string `json:"signature" valid:"required"`
ExpiresAt time.Time `json:"expires-at" valid:"required" bson:"expires_at"`
Scope []string `json:"scope" valid:"required" bson:"scope"`
ClientID bson.ObjectId `json:"client-id" valid:"-" bson:"client_id"`
ResourceOwnerID *bson.ObjectId `json:"resource-owner-id" valid:"-" bson:"resource_owner_id"`
}
AccessToken is the built-in model used to store access tokens.
func (*AccessToken) GetTokenData ¶
func (t *AccessToken) GetTokenData() *TokenData
GetTokenData implements the Token interface.
func (*AccessToken) SetTokenData ¶
func (t *AccessToken) SetTokenData(data *TokenData)
SetTokenData implements the Token interface.
func (*AccessToken) TokenIdentifier ¶
func (t *AccessToken) TokenIdentifier() string
TokenIdentifier implements the Token interface.
type Application ¶
type Application struct {
fire.Base `json:"-" bson:",inline" fire:"applications"`
Name string `json:"name" valid:"required"`
Key string `json:"key" valid:"required"`
SecretHash []byte `json:"-" valid:"required"`
Scope string `json:"scope" valid:"required"`
RedirectURI string `json:"redirect_uri" valid:"required"`
}
Application is the built-in model used to store clients.
func (*Application) ClientIdentifier ¶
func (a *Application) ClientIdentifier() string
ClientIdentifier implements the Client interface.
func (*Application) ValidRedirectURI ¶
func (a *Application) ValidRedirectURI(uri string) bool
ValidRedirectURI implements the Client interface.
func (*Application) ValidSecret ¶
func (a *Application) ValidSecret(secret string) bool
ValidSecret implements the Client interface.
type Authenticator ¶
type Authenticator struct {
// contains filtered or unexported fields
}
An Authenticator provides OAuth2 based authentication. The implementation currently supports the Resource Owner Credentials Grant, Client Credentials Grant and Implicit Grant.
func New ¶
func New(store *fire.Store, policy *Policy) *Authenticator
New constructs a new Authenticator from a store and policy.
func (*Authenticator) Authorizer ¶
Authorizer returns a middleware that can be used to authorize a request by requiring an access token with the provided scopes to be granted.
type Client ¶
type Client interface {
fire.Model
ClientIdentifier() string
ValidRedirectURI(string) bool
ValidSecret(string) bool
}
Client is the interface that must be implemented to provide a custom client fire.
type GrantRequest ¶
type GrantRequest struct {
Scope []string
Client Client
ResourceOwner ResourceOwner
}
A GrantRequest is used in conjunction with the GrantStrategy.
type GrantStrategy ¶
type GrantStrategy func(req *GrantRequest) (bool, []string)
The GrantStrategy is invoked by the authenticator with the grant type, the requested scope, the client and the resource owner before issuing an access token. The callback should return the scopes that should be granted.
Note: The Owner is not set for a client credentials grant.
type Policy ¶
type Policy struct {
Secret []byte
PasswordGrant bool
ClientCredentialsGrant bool
ImplicitGrant bool
AccessToken Token
RefreshToken Token
Client Client
ResourceOwner ResourceOwner
GrantStrategy GrantStrategy
AccessTokenLifespan time.Duration
RefreshTokenLifespan time.Duration
}
A Policy configures the provided authentication schemes.
func DefaultPolicy ¶
DefaultPolicy returns a simple policy that uses all built-in models and strategies.
type RefreshToken ¶
type RefreshToken struct {
fire.Base `json:"-" bson:",inline" fire:"refresh-tokens:refresh_tokens"`
Signature string `json:"signature" valid:"required"`
ExpiresAt time.Time `json:"expires-at" valid:"required" bson:"expires_at"`
Scope []string `json:"scope" valid:"required" bson:"scope"`
ClientID bson.ObjectId `json:"client-id" valid:"-" bson:"client_id"`
ResourceOwnerID *bson.ObjectId `json:"resource-owner-id" valid:"-" bson:"resource_owner_id"`
}
RefreshToken is the built-in model used to store refresh tokens.
func (*RefreshToken) GetTokenData ¶
func (t *RefreshToken) GetTokenData() *TokenData
GetTokenData implements the Token interface.
func (*RefreshToken) SetTokenData ¶
func (t *RefreshToken) SetTokenData(data *TokenData)
SetTokenData implements the Token interface.
func (*RefreshToken) TokenIdentifier ¶
func (t *RefreshToken) TokenIdentifier() string
TokenIdentifier implements the Token interface.
type ResourceOwner ¶
type ResourceOwner interface {
fire.Model
ResourceOwnerIdentifier() string
ValidPassword(string) bool
}
ResourceOwner is the interface that must be implemented to provide a custom resource owner fire.
type Token ¶
type Token interface {
fire.Model
TokenIdentifier() string
GetTokenData() *TokenData
SetTokenData(*TokenData)
}
Token is the interface that must be implemented to provide a custom access token and refresh token fire.
type TokenData ¶
type TokenData struct {
Signature string
Scope []string
ExpiresAt time.Time
ClientID bson.ObjectId
ResourceOwnerID *bson.ObjectId
}
TokenData is used to carry token related information.
type User ¶
type User struct {
fire.Base `json:"-" bson:",inline" fire:"users"`
Name string `json:"name" valid:"required"`
Email string `json:"email" valid:"required"`
PasswordHash []byte `json:"-" valid:"required"`
}
User is the built-in model used to store resource owners.
func (*User) ResourceOwnerIdentifier ¶
ResourceOwnerIdentifier implements the ResourceOwner interface.
func (*User) ValidPassword ¶
ValidPassword implements the ResourceOwner interface.
