多版本对象权限
开发过程中，您有任何问题可以在github上提交issue，或者在华为云对象存储服务论坛中发帖求助。接口参考文档详细介绍了每个接口的参数和使用方法。
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);
}
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/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);
}
