Functions

func BadRequestf

func BadRequestf(w http.ResponseWriter, f string, args ...interface{})

BadRequestf writes the given bad request message to the given ResponseWriter. It should be used by IDPs when they do not have enough state to pass the error message along to the initiating page.

func DischargeID

func DischargeID(req *http.Request) string

DischargeID gets the discharge ID from the given request using the standard form value.

func GetLoginMethods

func GetLoginMethods(ctx context.Context, c *httprequest.Client, u *url.URL, v interface{}) error

GetLoginMethods uses c to perform a request to get the list of available login methods from u. The result is unmarshalled into v.

func HandleLoginForm

func HandleLoginForm(
	ctx context.Context,
	w http.ResponseWriter,
	req *http.Request,
	idpChoice params.IDPChoiceDetails,
	tmpl *template.Template,
	loginUser func(ctx context.Context, username, password string) (*store.Identity, error),
) (*store.Identity, error)

HandleLoginForm is a handler that displays and process a standard login form.

func NameWithDomain

func NameWithDomain(name, domain string) string

NameWithDomain builds a name out of name and domain. If domain is empty then name is returned unchanged.

func RedirectURL

func RedirectURL(prefix, path, state string) string

RedirectURL creates a URL addressed to the given path within the IDP handler and adds the given state.

func RegistrationForm

func RegistrationForm(ctx context.Context, w http.ResponseWriter, params RegistrationParams, t *template.Template) error

RegistrationForm writes a registration form to the given writer using the given parameters.

func RequestParams

func RequestParams(ctx context.Context, w http.ResponseWriter, req *http.Request) httprequest.Params

RequestParams creates an httprequest.Params object from the given fields.

func ServiceURL

func ServiceURL(location, dest string) string

ServiceURL determines the URL within the specified location. If the given dest is a relative URL then a new url is calculated relative to location, otherwise it is returned unchanged.

func State

func State(req *http.Request) string

State gets the state from the given request using the standard form value.

func URL

func URL(prefix, path, dischargeID string) string

URL creates a URL addressed to the given path within the IDP handler and adds the given dischargeID (when specified).
