对象存储服务 OBS

设置多版本对象访问权限

您可以通过ObsClient.SetObjectAcl接口传入版本号（VersionId）设置多版本对象的访问权限，示例代码如下：

// 初始化配置参数
ObsConfig config = new ObsConfig();
config.Endpoint = "https://your-endpoint";
// 认证用的ak和sk硬编码到代码中或者明文存储都有很大的安全风险，建议在配置文件或者环境变量中密文存放，使用时解密，确保安全；本示例以ak和sk保存在环境变量中为例，运行本示例前请先在本地环境中设置环境变量AccessKeyID和SecretAccessKey。
// 您可以登录访问管理控制台获取访问密钥AK/SK，获取方式请参见https://support.huaweicloud.com/usermanual-ca/ca_01_0003.html
string accessKey= Environment.GetEnvironmentVariable("AccessKeyID", EnvironmentVariableTarget.Machine);
string secretKey= Environment.GetEnvironmentVariable("SecretAccessKey", EnvironmentVariableTarget.Machine);
// 创建ObsClient实例
ObsClient client = new ObsClient(accessKey, secretKey, config);
// 设置多版本对象访问权限
try
{
    SetObjectAclRequest request = new SetObjectAclRequest();
    request.BucketName = "bucketname";
    request.ObjectKey = "objectname";
    request.VersionId = "versionId";
    request.AccessControlList = new AccessControlList();
    Owner owner = new Owner();
    owner.Id = "ownerid";
    request.AccessControlList.Owner = owner;
    Grant item = new Grant();
    item.Permission = PermissionEnum.FullControl;
    item.Grantee = new GroupGrantee(GroupGranteeEnum.AllUsers);
    request.AccessControlList.Grants.Add(item);
    SetObjectAclResponse response = client.SetObjectAcl(request);
    Console.WriteLine("Set object acl response: {0}", response.StatusCode);
}
catch (ObsException ex)
{
    Console.WriteLine("ErrorCode: {0}", ex.ErrorCode);
    Console.WriteLine("ErrorMessage: {0}", ex.ErrorMessage);
}
