Functions

func AddRequestContextToHttpContext

func AddRequestContextToHttpContext(r *http.Request, rc RequestContext)

func GetJsonFields

func GetJsonFields(prefix string, m map[string]interface{}, result JsonFields)

func TimeoutHandler

func TimeoutHandler(next http.Handler, timeout time.Duration, apiErr *errorz.ApiError, mapper ResponseMapper) http.Handler

TimeoutHandler will create a http.Handler that wraps the given http.Handler. If the given timeout is reached, the supplied errorz.ApiError and ResponseMapper will be used to create an error response. This handler assumes JSON output.

This handler functions by creating a proxy ResponseWriter that is passed to downstream http.Handlers. This proxy ResponseWriter is ignored on timeout and panics. On panic, a blank response is returned with a 500 Internal Error status code. Downstream handlers are encouraged to implement their own panic recovery.

func WrapCorsHandler

func WrapCorsHandler(innerHandler http.Handler) http.Handler
