Functions

func AsJSON

func AsJSON(next chain.Handler) chain.Handler

func Authenticate

func Authenticate(authenticator auth.Authenticator) chain.Middleware

Authenticate uses the provided authenticator to authenticate the request. On success, it yields to the next handler in the chain. On failure, it renders 401 Unauthorized.

func CheckAPIVersion

func CheckAPIVersion(serverVersion string) chain.Middleware

CheckAPIVersion checks that the request has a Draupnir-Version header with a version that matches the server's major version, and is equal to or lower than the minor version.

If the version doesn't match or the header is missing, it renders a 400 Bad Request.

func DefaultErrorRenderer

func DefaultErrorRenderer(next chain.Handler) chain.Handler

func GetAuthenticatedUser

func GetAuthenticatedUser(r *http.Request) (string, error)

func GetLogger

func GetLogger(r *http.Request) (log.Logger, error)

func NewErrorHandler

func NewErrorHandler(logger log.Logger) chain.TerminatingMiddleware

func NewRequestLogger

func NewRequestLogger(logger log.Logger) chain.Middleware

func NewSentryReporter

func NewSentryReporter(sentry *raven.Client) chain.Middleware

func WithVersion
