获取对象访问权限

您可以通过ObsClient.GetObjectAcl获取对象的访问权限。以下代码展示如何获取对象访问权限：

// 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);
// 获取对象访问权限
try
{
    GetObjectAclRequest request = new GetObjectAclRequest();
    request.BucketName = "bucketname";
    request.ObjectKey = "objectname";
    GetObjectAclResponse response = client.GetObjectAcl(request);
    Console.WriteLine("Get bucket acl response: {0}", response.StatusCode);
    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);
}
