type Provider struct {
	ClientKey   string
	Secret      string
	CallbackURL string
	HTTPClient  *http.Client

New creates a new Twitch provider, and sets up important connection details. You should always call `twitch.New` to get a new Provider. Never try to create one manually.

func (*Provider) BeginAuth

func (p *Provider) BeginAuth(state string) (goth.Session, error)

func (*Provider) Client

func (p *Provider) Client() *http.Client

Client ...

func (*Provider) Debug

func (p *Provider) Debug(debug bool)

func (*Provider) FetchUser

func (p *Provider) FetchUser(session goth.Session) (goth.User, error)

FetchUser will go to Twitch and access basic info about the user.

func (*Provider) Name

	AccessToken  string
	RefreshToken string
	ExpiresAt    time.Time
}

Session stores data during the auth process with Twitch

func (*Session) Authorize

func (s *Session) Authorize(provider goth.Provider, params goth.Params) (string, error)

Authorize completes the authorization with Twitch and returns the access token to be stored for future use.

func (Session) GetAuthURL

func (s Session) GetAuthURL() (string, error)

GetAuthURL will return the URL set by calling the `BeginAuth` function on the Twitch provider.

func (Session) Marshal
