-- This example requires the Chilkat API to have been previously unlocked.
-- See Global Unlock Sample for sample code.

-- This example duplicates the following CURL statement provided in the hotelbeds.com "Getting Started"
-- developer documentation:

-- #!/bin/bash
-- apiKey="yourApiKey"
-- secret="yourSecret"
-- curl -i \
--   -X GET \
--   -H 'Accept:application/json' \
--   -H 'Api-key:'$apiKey'' \
--   -H 'X-Signature:'$(echo -n ${apiKey}${secret}$(date +%s)|sha256sum|awk '{ print $1}')'' \
--   https://api.test.hotelbeds.com/hotel-api/1.0/status

-- The "date + %s" command emits a UNIX date/time number such as 1605548842
-- We need to concatenate the apiKey, secret, and current date/time in UNIX (numeric) time format.
local dt = chilkat.DateTime.new()
dt:set_from_current_system_time()
-- Get the UNIX time string in the GMT timezone.
local bLocalTime = false
local unixTimeStr = dt:get_as_unix_time_str(bLocalTime)
print(unixTimeStr)

-- Use your own API key and secret.  (These are not valid values)
local apiKey = "227b20a2cb705e45f3b0a0944672dc07"
local secret = "54dc7ba9e2"

local sb = chilkat.StringBuilder.new()
sb:append(apiKey)
sb:append(secret)
sb:append(unixTimeStr)

local crypt = chilkat.Crypt2.new()
crypt.hash_algorithm = "sha256"
crypt.encoding_mode = "hexlower"
local signature = crypt:hash_string_enc(sb:get_as_string())

print(signature)

local http = chilkat.Http.new()

http:set_request_header("Accept", "application/json")
http:set_request_header("Api-key", apiKey)
http:set_request_header("X-Signature", signature)
