Types

type Config

type Config struct {
	// Email is the OAuth client identifier used when communicating with
	// the configured OAuth provider.
	Email string

	// PrivateKey contains the contents of an RSA private key or the
	// contents of a PEM file that contains a private key. The provided
	// private key is used to sign JWT payloads.
	// PEM containers with a passphrase are not supported.
	// Use the following command to convert a PKCS 12 file into a PEM.
	//
	//    $ openssl pkcs12 -in key.p12 -out key.pem -nodes
	//
	PrivateKey []byte

	// PrivateKeyID contains an optional hint indicating which key is being
	// used.
	PrivateKeyID string

	// Subject is the optional user to impersonate.
	Subject string

	// Scopes optionally specifies a list of requested permission scopes.
	Scopes []string

	// TokenURL is the endpoint required to complete the 2-legged JWT flow.
	TokenURL string

	// Expires optionally specifies how long the token is valid for.
	Expires time.Duration

	// Audience optionally specifies the intended audience of the
	// request.  If empty, the value of TokenURL is used as the
	// intended audience.
	Audience string

	// PrivateClaims optionally specifies custom private claims in the JWT.
	// See http://tools.ietf.org/html/draft-jones-json-web-token-10#section-4.3
	PrivateClaims map[string]interface{}

	// UseIDToken optionally specifies whether ID token should be used instead
	// of access token when the server returns both.
	UseIDToken bool

Config is the configuration for using JWT to fetch tokens, commonly known as "two-legged OAuth 2.0".

func (*Config) Client

func (c *Config) Client(ctx context.Context) *http.Client

Client returns an HTTP client wrapping the context's HTTP transport and adding Authorization headers with tokens obtained from c.

The returned client and its Transport should not be modified.

func (*Config) TokenSource

func (c *Config) TokenSource(ctx context.Context) oauth2.TokenSource

TokenSource returns a JWT TokenSource using the configuration in c and the HTTP client from the provided context.
