responsewriter

This package contains code forked from github.com/urfave/negroni. It includes extensive changes, including the removal of features that depend on the rest of the framework, and additions of things we need to support integrations with the rest of Dapr, such as support for user values.

Types

type ResponseWriter

type ResponseWriter interface {
	http.ResponseWriter

	// Status returns the status code of the response or 0 if the response has
	// not been written
	Status() int
	// Written returns whether or not the ResponseWriter has been written.
	Written() bool
	// Size returns the size of the response body.
	Size() int
	// Before allows for a function to be called before the ResponseWriter has been written to. This is
	// useful for setting headers or any other operations that must happen before a response has been written.
	Before(func(ResponseWriter))
}

ResponseWriter is a wrapper around http.ResponseWriter that provides extra information about the response. It is recommended that middleware handlers use this construct to wrap a responsewriter if the functionality calls for it.

func EnsureResponseWriter

func EnsureResponseWriter(rw http.ResponseWriter) ResponseWriter

EnsureResponseWriter creates a ResponseWriter that wraps a http.ResponseWriter, unless it's already a ResponseWriter.

func NewResponseWriter

func NewResponseWriter(rw http.ResponseWriter) ResponseWriter

NewResponseWriter creates a ResponseWriter that wraps a http.ResponseWriter
