Create a Google Cloud Storage Bucket

See more Google Cloud Storage Examples

Demonstrates how to create a Google Cloud Storage bucket. Dart

import 'package:chilkat/chilkat.dart';

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

  // This example uses a previously obtained access token having permission for the 
  // scope "https://www.googleapis.com/auth/cloud-platform"

  // In this example, Get Google Cloud Storage OAuth2 Access Token, 
  // the service account access token was saved to a text file.  This example fetches the access token from the file..
  final sbToken = CkStringBuilder();
  sbToken.loadFile('qa_data/tokens/googleCloudStorageAccessToken.txt', 'utf-8');

  // ---- Step 1
  // Create a JSON that contains the following information, replacing [VALUES_IN_BRACKETS] with the appropriate values:

  // {
  //   "name": "[BUCKET_NAME]",
  //   "location": "[BUCKET_LOCATION]",
  //   "storageClass": "[STORAGE_CLASS]"
  // }

  final json = CkJsonObject();
  json.updateString('name', 'chilkat-ocean');
  json.updateString('location', 'us');
  json.updateString('storageClass', 'multi_regional');

  // ---- Step 2
  // Send a POST equivalent to this curl command

  // curl -X POST --data-binary @[JSON_FILE_NAME].json \
  //      -H "Authorization: Bearer [OAUTH2_TOKEN]" \
  //      -H "Content-Type: application/json" \
  //      "https://www.googleapis.com/storage/v1/b?project=[PROJECT_ID]"

  final http = CkHttp();
  http.authToken = sbToken.getAsString();

  http.setUrlVar('project_id', 'chilkat-176611');
  final url = 'https://www.googleapis.com/storage/v1/b?project={\$project_id}';
  final resp = CkHttpResponse();
  try {
    http.httpJson('POST', url, json, 'application/json', resp);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  final responseCode = resp.statusCode;
  if (responseCode == 401) {
    print(resp.bodyStr);
    print('If invalid credentials, then it is likely the access token expired.');
    print('Your app should automatically fetch a new access token and re-try.');
    return;
  }

  print('Response code: $responseCode');
  print('Response body');
  print(resp.bodyStr);

  // A successful response looks like this:
  // Response code: 200
  // Response body
  // {
  //  "kind": "storage#bucket",
  //  "id": "chilkat-ocean",
  //  "selfLink": "https://www.googleapis.com/storage/v1/b/chilkat-ocean",
  //  "projectNumber": "933037264567",
  //  "name": "chilkat-ocean",

  //  "updated": "2017-08-13T12:27:10.811Z",
  //  "metageneration": "1",
  //  "location": "US",
  //  "storageClass": "MULTI_REGIONAL",
  //  "etag": "CAE="
  // }
  // 

  // Parse the JSON response:
  final jsonResp = CkJsonObject();
  jsonResp.load(resp.bodyStr);

  print('name: ${jsonResp.stringOf('name')}');
  print('timeCreated: ${jsonResp.stringOf('timeCreated')}');

  // Parse the date/time created.
  final dt = CkDateTime();
  dt.setFromTimestamp(jsonResp.stringOf('timeCreated'));
  // ...
