Types

type Client 

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

Client is the interface for the Firebase auth service.

Client facilitates generating custom JWT tokens for Firebase clients, and verifying ID tokens issued by Firebase backend services.

func NewClient 

func NewClient(ctx context.Context, c *internal.AuthConfig) (*Client, error)

NewClient creates a new instance of the Firebase Auth Client.

This function can only be invoked from within the SDK. Client applications should access the Auth service through firebase.App.

func (*Client) CreateUser 

func (c *Client) CreateUser(ctx context.Context, user *UserToCreate) (*UserRecord, error)

CreateUser creates a new user with the specified properties.

func (*Client) CustomToken 

func (c *Client) CustomToken(uid string) (string, error)

CustomToken creates a signed custom authentication token with the specified user ID. The resulting JWT can be used in a Firebase client SDK to trigger an authentication flow. See https://firebase.google.com/docs/auth/admin/create-custom-tokens#sign_in_using_custom_tokens_on_clients for more details on how to use custom tokens for client authentication.

func (*Client) CustomTokenWithClaims 

func (c *Client) CustomTokenWithClaims(uid string, devClaims map[string]interface{}) (string, error)

CustomTokenWithClaims is similar to CustomToken, but in addition to the user ID, it also encodes all the key-value pairs in the provided map as claims in the resulting JWT.

func (*Client) DeleteUser 

func (c *Client) DeleteUser(ctx context.Context, uid string) error

DeleteUser deletes the user by the given UID.

func (*Client) GetUser 

func (c *Client) GetUser(ctx context.Context, uid string) (*UserRecord, error)

GetUser gets the user data corresponding to the specified user ID.

func (*Client) GetUserByEmail 

func (c *Client) GetUserByEmail(ctx context.Context, email string) (*UserRecord, error)

GetUserByEmail gets the user data corresponding to the specified email.

func (*Client) GetUserByPhoneNumber 

func (c *Client) GetUserByPhoneNumber(ctx context.Context, phone string) (*UserRecord, error)

GetUserByPhoneNumber gets the user data corresponding to the specified user phone number.

func (*Client) RevokeRefreshTokens 

func (c *Client) RevokeRefreshTokens(ctx context.Context, uid string) error

RevokeRefreshTokens revokes all refresh tokens issued to a user.

RevokeRefreshTokens updates the user's TokensValidAfterMillis to the current UTC second. It is important that the server on which this is called has its clock set correctly and synchronized.

While this revokes all sessions for a specified user and disables any new ID tokens for existing sessions from getting minted, existing ID tokens may remain active until their natural expiration (one hour). To verify that ID tokens are revoked, use `verifyIdTokenAndCheckRevoked(ctx, idToken)`.

func (*Client) SetCustomUserClaims 

func (c *Client) SetCustomUserClaims(ctx context.Context, uid string, customClaims map[string]interface{}) error

SetCustomUserClaims sets additional claims on an existing user account.

Custom claims set via this function can be used to define user roles and privilege levels. These claims propagate to all the devices where the user is already signed in (after token expiration or when token refresh is forced), and next time the user signs in. The claims can be accessed via the user's ID token JWT. If a reserved OIDC claim is specified (sub, iat, iss, etc), an error is thrown. Claims payload must also not be larger then 1000 characters when serialized into a JSON string.

func (*Client) UpdateUser 

func (c *Client) UpdateUser(ctx context.Context, uid string, user *UserToUpdate) (ur *UserRecord, err error)

UpdateUser updates an existing user account with the specified properties.

DisplayName, PhotoURL and PhoneNumber will be set to "" to signify deleting them from the record.

func (*Client) Users 

func (c *Client) Users(ctx context.Context, nextPageToken string) *UserIterator

Users returns an iterator over Users.

If nextPageToken is empty, the iterator will start at the beginning. If the nextPageToken is not empty, the iterator starts after the token.

func (*Client) VerifyIDToken 

func (c *Client) VerifyIDToken(idToken string) (*Token, error)

VerifyIDToken verifies the signature and payload of the provided ID token.

VerifyIDToken accepts a signed JWT token string, and verifies that it is current, issued for the correct Firebase project, and signed by the Google Firebase services in the cloud. It returns a Token containing the decoded claims in the input JWT. See https://firebase.google.com/docs/auth/admin/verify-id-tokens#retrieve_id_tokens_on_clients for more details on how to obtain an ID token in a client app. This does not check whether or not the token has been revoked. See `VerifyIDTokenAndCheckRevoked` below.

func (*Client) VerifyIDTokenAndCheckRevoked 

func (c *Client) VerifyIDTokenAndCheckRevoked(ctx context.Context, idToken string) (*Token, error)

VerifyIDTokenAndCheckRevoked verifies the provided ID token and checks it has not been revoked.

VerifyIDTokenAndCheckRevoked verifies the signature and payload of the provided ID token and checks that it wasn't revoked. Uses VerifyIDToken() internally to verify the ID token JWT.

type ExportedUserRecord 

type ExportedUserRecord struct {
	*UserRecord
	PasswordHash string
	PasswordSalt string
}

ExportedUserRecord is the returned user value used when listing all the users.

type Token 

type Token struct {
	Issuer   string                 `json:"iss"`
	Audience string                 `json:"aud"`
	Expires  int64                  `json:"exp"`
	IssuedAt int64                  `json:"iat"`
	Subject  string                 `json:"sub,omitempty"`
	UID      string                 `json:"uid,omitempty"`
	Claims   map[string]interface{} `json:"-"`
}

Token represents a decoded Firebase ID token.

Token provides typed accessors to the common JWT fields such as Audience (aud) and Expiry (exp). Additionally it provides a UID field, which indicates the user ID of the account to which this token belongs. Any additional JWT claims can be accessed via the Claims map of Token.

type UserInfo 

type UserInfo struct {
	DisplayName string
	Email       string
	PhoneNumber string
	PhotoURL    string
	// In the ProviderUserInfo[] ProviderID can be a short domain name (e.g. google.com),
	// or the identity of an OpenID identity provider.
	// In UserRecord.UserInfo it will return the constant string "firebase".
	ProviderID string
	UID        string
}

UserInfo is a collection of standard profile information for a user.

type UserIterator 

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

UserIterator is an iterator over Users.

func (*UserIterator) Next 

func (it *UserIterator) Next() (*ExportedUserRecord, error)

Next returns the next result. Its second return value is iterator.Done if there are no more results. Once Next returns iterator.Done, all subsequent calls will return iterator.Done.

func (*UserIterator) PageInfo 

func (it *UserIterator) PageInfo() *iterator.PageInfo

PageInfo supports pagination. See the google.golang.org/api/iterator package for details. Page size can be determined by the NewPager(...) function described there.

type UserMetadata 

type UserMetadata struct {
	CreationTimestamp  int64
	LastLogInTimestamp int64
}

UserMetadata contains additional metadata associated with a user account. Timestamps are in milliseconds since epoch.

type UserRecord 

type UserRecord struct {
	*UserInfo
	CustomClaims           map[string]interface{}
	Disabled               bool
	EmailVerified          bool
	ProviderUserInfo       []*UserInfo
	TokensValidAfterMillis int64 // milliseconds since epoch.
	UserMetadata           *UserMetadata
}

UserRecord contains metadata associated with a Firebase user account.
