CurlHTTP is a wrapper around LibCURL that provides a more Julia like interface to doing HTTP via Curl.
In particular, this module implements the CurlEasy and CurlMulti interfaces for curl, and allows using Client TLS certificates.
This module reexports LibCURL so everything available in LibCURL will be available when this module is used.
See https://curl.se/libcurl/c/libcurl-tutorial.html for a tutorial on using libcurl in C. The Julia interface should be similar.

curl = CurlEasy(
url="https://postman-echo.com/get?foo=bar",

)
res, http_status, errormessage = curl_execute(curl)
# curl.userdata[:databuffer] is a Vector{UInt8} containing the bytes of the response
responseBody = String(curl.userdata[:databuffer])
# curl.userdata[:responseHeaders] is a Vector{String} containing the response headers
