go-curl

go-curl is a GoLang interface to libcurl, the multiprotocol file transfer library. Similar to the HTTP support in [net/http] (https://pkg.go.dev/net/http), go-curl can be used to fetch objects from a Go program. While go-curl can provide simple fetches, it also exposes most of the functionality of libcurl, including:

• Speed - libcurl is very fast.
• Multiple protocol (not just HTTP).
• SSL, authentication and proxy support.
• Support for libcurl's callbacks.

This said, libcurl API can be less easy to learn than net/http.
