import 'package:chilkat/chilkat.dart';

void main() {
  // This example assumes the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  final http = CkHttp();

  // Adds the "Authorization: Bearer $OPENAI_API_KEY" header.
  // This is NOT a real key.  Change the "sk-vi...." to your own key.
  http.authToken = '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';

  final fileId = 'file-1H4vJq0H775gQVrjWY5jpp15';

  // Download to local file.
  final url = 'https://api.openai.com/v1/files/{\$file_id}/content';
  http.setUrlVar('file_id', fileId);

  // Note: Free accounts are not able to download files.
  // If using a free account, you'll receive an error response:  "To help mitigate abuse, downloading of fine-tune training files is disabled for free accounts."
  try {
    http.download(url, 'c:/aaworkarea/mydata.jsonl');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    print('Failed');
    return;
  }

  print('Downloaded OpenAI file to a local file.');

  // Alternatively, download into a StringBuilder
  final sbData = CkStringBuilder();
  try {
    http.downloadSb(url, 'utf-8', sbData);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
