# 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.
dt = Chilkat::CkDateTime.new()
dt.SetFromCurrentSystemTime()
# Get the UNIX time string in the GMT timezone.
bLocalTime = false
unixTimeStr = dt.getAsUnixTimeStr(bLocalTime)
print unixTimeStr + "\n";

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

sb = Chilkat::CkStringBuilder.new()
sb.Append(apiKey)
sb.Append(secret)
sb.Append(unixTimeStr)

crypt = Chilkat::CkCrypt2.new()
crypt.put_HashAlgorithm("sha256")
crypt.put_EncodingMode("hexlower")
signature = crypt.hashStringENC(sb.getAsString())

print signature + "\n";

http = Chilkat::CkHttp.new()

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

jsonResponse = http.quickGetStr("https://api.test.hotelbeds.com/hotel-api/1.0/status")
print jsonResponse + "\n";
print http.get_LastStatus().to_s() + "\n";
