func ConfigOAuth added in v1.56.0

func ConfigOAuth(ctx context.Context, name string, m configmap.Mapper, ri *fs.RegInfo, in fs.ConfigIn) (*fs.ConfigOut, error)

ConfigOAuth does the oauth config specified in the config block

This is called with a state which has pushed on it

state prefixed with "*oauth"
state for oauth to return to
state that returned the OAuth when we wish to recall it
value that returned the OAuth

func ConfigOut added in v1.56.0

func ConfigOut(state string, oAuth *Options) (*fs.ConfigOut, error)

ConfigOut returns a config item suitable for the backend config

state is the place to return the config to oAuth is the config to run the oauth with

func Context

func Context(ctx context.Context, client *http.Client) context.Context

Context returns a context with our HTTP Client baked in for oauth2

func GetToken

func GetToken(name string, m configmap.Mapper) (*oauth2.Token, error)

GetToken returns the token saved in the config file under section name.

func PutToken

func PutToken(name string, m configmap.Mapper, token *oauth2.Token, newSection bool) error

PutToken stores the token in the config file

This saves the config file if it changes

Types

type AuthResult added in v1.6.1

type AuthResult struct {
	OK          bool // Failure or Success?
	Name        string
	Description string

	Form        url.Values // the complete contents of the form
	Err         error      // any underlying error to report
}

AuthResult is returned from the web server after authorization success or failure

func (*AuthResult) Error added in v1.6.1

func (ar *AuthResult) Error() string

type CheckAuthFn added in v1.6.1

type CheckAuthFn func(*oauth2.Config, *AuthResult) error

CheckAuthFn is called when a good Auth has been received

type Options added in v1.50.20

type Options struct {
	OAuth2Config *oauth2.Config          // Basic config for oauth2
	NoOffline    bool                    // If set then "access_type=offline" parameter is not passed
	CheckAuth    CheckAuthFn             // When the AuthResult is known the checkAuth function is called if set
	OAuth2Opts   []oauth2.AuthCodeOption // extra oauth2 options
	StateBlankOK bool                    // If set, state returned as "" is deemed to be OK

It will only renew the token if the number of uploads > 0

func (*Renew) Expire added in v1.59.1

func (r *Renew) Expire() error

Expire expires the token source

func (*Renew) Invalidate

func (r *Renew) Invalidate()

func (*Renew) Start

func (r *Renew) Start()

Start should be called before starting an upload

func (*Renew) Stop

func (r *Renew) Stop()

type TokenSource

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