func NewTransportWithFallbackHeaders ¶

func NewTransportWithFallbackHeaders(t http.RoundTripper, headers http.Header) http.RoundTripper

NewTransportWithFallbackHeaders creates a new http.RoundTripper that wraps the given http.RoundTripper and adds the given headers to the request if they are not already set.

This is useful if you want to ensure a signed header like `Content-Type` is set on all requests, including GETs.
