Backblaze S3 Upload String

See more Backblaze S3 Examples

Demonstrates how to upload the contents of a string to an 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 = 'orchard.json';
  final contentType = 'application/json';

  http.keepResponseBody = true;

  // Let's say we have JSON in a string and want to upload it to a file in Backblaze..
  final jsonStr = '{ "orchard": "apple" }';

  // The charset indicates the byte representation of what is uploaded.
  // If needed, Chilkat will internally convert to the desired byte representation before uploading.
  final charset = 'utf-8';

  try {
    http.s3UploadString(jsonStr, charset, contentType, bucketName, objectName);
    print('String uploaded.');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);

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