Backblaze S3 Upload File

See more Backblaze S3 Examples

Demonstrates how to upload a file to a Backblaze bucket.

The Chilkat S3 functions in the HTTP class are compatible with the Backblaze service. However, because of some specific issues, Chilkat v9.5.0.89 or later is needed.

Dart

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();

  // keyID = Access Key ID or Access Key
  http.awsAccessKey = 'access-key';

  // applicationKey = Secret Access Key or Secret Key
  http.awsSecretKey = 'secret-key';

  // Region is the 2nd part of your S3 Endpoint
  http.awsEndpoint = 's3.us-west-002.backblazeb2.com';

  final bucketName = 'chilkat-test';
  final objectName = 'seahorse.jpg';
  final localFilePath = 'qa_data/jpg/seahorse.jpg';
  final contentType = 'image/jpg';

  http.keepResponseBody = true;

  try {
    http.s3UploadFile(localFilePath, contentType, bucketName, objectName);
    print('File uploaded.');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);

    final xml = CkXml();
    xml.loadXml(http.lastResponseBody);
    print(xml.getXml());
  }
