Is there a way for a Callout to inspect the method and path on the request?

[DinoChiesa]

I am looking through the Java callout examples. I don't see a way for the Callout to see the method or path on the request.

Envoyproxy has "pseudo headers" of :path and :method, but I have not been able to retrieve values for them.

BTW is this really the simplest way to retrieve a header value?

  private static String getHeader(HttpHeaders headers, String headerName) {
    return headers.getHeaders().getHeadersList().stream()
        .filter(header -> headerName.equalsIgnoreCase(header.getKey()))
        .map(header -> new String(header.getRawValue().toByteArray(), StandardCharsets.UTF_8))
        .findFirst()
        .orElse(null);
  }

EDIT Check that. I had configured the service extension to receive only a specific set of headers. (Check this doc) . When I removed the forwardHeaders element, my Callout got all the headers, including the pseudo headers.

Still have a remaining question ... is that ^^ the correct way to get a single header?
