Method Header

recorder_test.go:73–80

Header implements http.ResponseWriter. It returns the response headers to mutate within a handler. To test the headers that were written after a handler completes, use the Result method and see the returned Response value's Header.

// written after a handler completes, use the Result method and see
// the returned Response value's Header.
func (rw *ResponseRecorder) Header() http.Header {
	m := rw.HeaderMap
	if m == nil {
		m = make(http.Header)
		rw.HeaderMap = m
	}
	return m
}

// writeHeader writes a header if it was not written yet and
// detects Content-Type if needed.
