Function regexPathTerminatedWithMarker

app/api/middleware/encode/encode.go:240–262

regexPathTerminatedWithMarker is similar to pathTerminatedWithMarker but with regex prefix support. Example: 1. Path: "/registry/app1%2Fremote2/artifact/foo/bar/+/summary" Prefix: => "^/registry/([^/]+)/artifact/" Marker: => "/+" MarkerReplacement: => "" ==> "/registry/app1%2Fremote2/artifact/foo%2

(
	r *http.Request,
	regexPrefix string,
	marker string,
	markerReplacement string,
)

// ==> "/registry/abc/artifact/foo%2Fbar/summary"

func regexPathTerminatedWithMarker(
	r *http.Request,
	regexPrefix string,
	marker string,
	markerReplacement string,
) (bool, error) {
	prefixPattern := regexp.MustCompile(regexPrefix)

	matches := prefixPattern.FindStringSubmatch(r.URL.Path)
	// In case path doesn't start with prefix - nothing to encode
	if len(matches) == 0 {
		return false, nil
	}

	// We only care about the first match as we provide prefix
	prefix := matches[0]

	urlPath := r.URL.Path
	if r.URL.RawPath != "" {
		urlPath = r.URL.RawPath
	}
	return pathTerminatedWithMarkerAndURL(r, prefix, marker, markerReplacement, urlPath)
}

// cutOutTerminatedPath cuts out the resource path terminated with the provided marker (path segment suffix).
// e.g. subPath: "/space1/space2/+/authToken", marker: "/+" => "/space1/space2"
