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.

- a Multipart Form supports file uploading
- Most curl_easy_setopt option
- partly implement share & multi interface
- new callback function prototype
- Any version of Go
- libcurl 7.x or higher (including development headers and static/dynamic libs)
- Python 3 (used only by configure scripts)
