putBucketTagging method

Future<Response> putBucketTagging({
  1. String? bucketName,
  2. String? region,
  3. required COSTagging tagging,
})

COS 支持为已存在的对象设置标签。PUT Object tagging 接口通过为对象添加键值对作为对象标签，可以协助您分组管理已有的对象资源 bucketName region tagging

Implementation

Future<Response> putBucketTagging({
  String? bucketName,
  String? region,
  required COSTagging tagging,
}) async {
  final Map<String, String> headers = <String, String>{};
  final String xmlString = tagging.toXmlString();
  // http 框架设置body时，会自动给 Content-Type 指定字符集为 charset=utf-8
  // 设置 application/xml; charset=utf-8 保持一致
  headers['Content-Type'] = 'application/xml; charset=utf-8';
  headers['Content-Length'] = xmlString.length.toString();
  final String md5String = Base64Encoder()
      .convert(md5.convert(xmlString.codeUnits).bytes)
      .toString();
  headers['Content-MD5'] = md5String;
  final Response response = await client.put(
    '${getBaseApiUrl(bucketName, region)}/?tagging',
    headers: headers,
    body: xmlString,
  );
  return toValidation(response);
