Special notes for reviews

plz downgrade the go version to no higher than 1.18 to keep it consistent with main package, so as to avoid introducing new features now or in the future and support more go versions

if extractedName := options.resourceExtract(r); extractedName != "" {
resourceName = extractedName
}
It looks the same as the code logic above? But readability will be improved
