Frequently Asked Questions

java.net.http.HttpClient, built into the JDK since Java 11 — no extra dependency required.

-X/--request, -H/--header, -d/--data (and --data-raw/--data-binary/--data-urlencode), -u/--user, -A/--user-agent, -b/--cookie, --url, and a bare URL. Other flags are ignored rather than causing an error.
