http.get(url, { options })

Parameters

  • result_str is set to "OK" if successful or contains a description of the failure.
  • result_code is the HTTP result code of the get.

function progress(total, current)
  local ratio = current / total;
  ratio = math.min(math.max(ratio, 0), 1);
  local percent = math.floor(ratio * 100);
  print("Download progress (" .. percent .. "%/100%)")
end

local resource, result_str, response_code = http.get("http://example.com/api.json", {
    progress = progress,
    headers = { "From: Premake", "Referer: Premake" },
    userpwd = "username:password"
})
