多版本对象权限
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/intl/zh-cn/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); }

ACL中需要填写的所有者(Owner)或者被授权用户(Grantee)的ID,是指用户的账号ID,可通过OBS控制台“我的凭证”页面查看。
获取多版本对象访问权限
您可以通过ObsClient.GetObjectAcl接口传入版本号(VersionId)获取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/intl/zh-cn/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); // 获取多版本访问权限 try { GetObjectAclRequest request = new GetObjectAclRequest(); request.BucketName = "bucketname"; request.ObjectKey = "objectname"; request.VersionId = "versionId"; GetObjectAclResponse response = client.GetObjectAcl(request); Console.WriteLine("GetObjectAcl grant account: {0}", response.AccessControlList.Grants.Count); Console.WriteLine("GetObjectAcl owner id: {0}", response.AccessControlList.Owner.Id); foreach (Grant grant in response.AccessControlList.Grants) { if(grant.Grantee is CanonicalGrantee) { Console.WriteLine("Grantee id: {0}", (grant.Grantee as CanonicalGrantee).Id); }else if(grant.Grantee is GroupGrantee) { Console.WriteLine("Grantee type: {0}", (grant.Grantee as GroupGrantee).GroupGranteeType); } Console.WriteLine("Grant permission: {0}", grant.Permission); } } } catch (ObsException ex) { Console.WriteLine("ErrorCode: {0}", ex.ErrorCode); Console.WriteLine("ErrorMessage: {0}", ex.ErrorMessage); }
