Types

type AuthenticationScheme

type AuthenticationScheme byte

AuthenticationScheme defines scheme of the authentication method

const (
	// BasicAuth is scheme for Basic HTTP Authentication RFC 7617
	BasicAuth AuthenticationScheme = 1 << iota
	// DigestAuth is scheme for HTTP Digest Access Authentication RFC 7616
	DigestAuth
	// BearerAuth is scheme for OAuth 2.0 Bearer Tokens RFC 6750
	BearerAuth
)

type Challenge

type Challenge struct {
	// scheme is the auth-scheme according to RFC 2617
	Scheme AuthenticationScheme

	// parameters are the auth-params according to RFC 2617
	Parameters map[string]string
}

Challenge carries information from a WWW-Authenticate response header. See RFC 2617.

func ParseAuthHeader

func ParseAuthHeader(header http.Header) []Challenge

ParseAuthHeader parses challenges from WWW-Authenticate header

type FetchTokenResponse

type FetchTokenResponse struct {
	Token        string    `json:"token"`
	AccessToken  string    `json:"access_token"`
	ExpiresIn    int       `json:"expires_in"`
	IssuedAt     time.Time `json:"issued_at"`
	RefreshToken string    `json:"refresh_token"`
}

FetchTokenResponse is response from fetching token with GET request

func FetchToken

func FetchToken(ctx context.Context, client *http.Client, headers http.Header, to TokenOptions) (*FetchTokenResponse, error)

FetchToken fetches a token using a GET request

type OAuthTokenResponse

type OAuthTokenResponse struct {
	AccessToken  string    `json:"access_token"`
	RefreshToken string    `json:"refresh_token"`
	ExpiresIn    int       `json:"expires_in"`
	IssuedAt     time.Time `json:"issued_at"`
	Scope        string    `json:"scope"`
}

OAuthTokenResponse is response from fetching token with a OAuth POST request

func FetchTokenWithOAuth

func FetchTokenWithOAuth(ctx context.Context, client *http.Client, headers http.Header, clientID string, to TokenOptions) (*OAuthTokenResponse, error)

FetchTokenWithOAuth fetches a token using a POST request

type TokenOptions

type TokenOptions struct {
	Realm    string
	Service  string
	Scopes   []string
	Username string
	Secret   string
}

TokenOptions are options for requesting a token

func GenerateTokenOptions

func GenerateTokenOptions(ctx context.Context, host, username, secret string, c Challenge) (TokenOptions, error)

GenerateTokenOptions generates options for fetching a token based on a challenge
