Demonstrates how to calculate the X-Signature header and add to requests sent to api.test.hotelbeds.com. Dart

  // 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.
  final dt = CkDateTime();
  dt.setFromCurrentSystemTime();
  // Get the UNIX time string in the GMT timezone.
  final bLocalTime = false;
  final unixTimeStr = dt.getAsUnixTimeStr(bLocalTime);
  print(unixTimeStr);

  // Use your own API key and secret.  (These are not valid values)
  final apiKey = '227b20a2cb705e45f3b0a0944672dc07';
  final secret = '54dc7ba9e2';

  final sb = CkStringBuilder();
  sb.append(apiKey);
  sb.append(secret);
  sb.append(unixTimeStr);

  final crypt = CkCrypt2();
  crypt.hashAlgorithm = 'sha256';
  crypt.encodingMode = 'hexlower';
  final signature = crypt.hashStringENC(sb.getAsString());

  print(signature);

  final http = CkHttp();

  http.setRequestHeader('Accept', 'application/json');
  http.setRequestHeader('Api-key', apiKey);
  http.setRequestHeader('X-Signature', signature);

  final jsonResponse = http.quickGetStr('https://api.test.hotelbeds.com/hotel-api/1.0/status');
  print(jsonResponse);
  print(http.lastStatus);

  // Sample output:  

  // 1605549542
  // 2146aefb36e7331b3b29aafd7638398ca22e689573224f1a71274d60bd201ec2
