OSS Upload String (Alibaba Cloud)

See more Alibaba Cloud OSS Examples

Demonstrates how to upload the contents of a string to an AliCloud OSS bucket.

The Chilkat S3 functions in the HTTP class are compatible with Alibaba Cloud's OSS service.

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();

  // Insert your AccessKey ID here:
  http.awsAccessKey = 'access-key';

  // Insert your AccessKey Secret here:
  http.awsSecretKey = 'secret-key';

  // To upload to a bucket located in a different region, use the endpoint for that region, such as "oss-cn-hangzhou.aliyuncs.com 	"
  // See Alibaba Object Storage Service Regions and Endpoints
  http.awsEndpoint = 'oss-us-east-1.aliyuncs.com';

  final bucketName = 'chilkat';
  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 Aliyun..
  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());
  }
