分页列举全部多版本对象

以下代码展示分页列举全部多版本对象:

// 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);
//分页列举全部多版本对象
try
{
    ListVersionsRequest request = new ListVersionsRequest();
    request.BucketName = "bucketname";
    request.MaxKeys = 100;
    ListVersionsResponse response;
    do
    {
        response = client.ListVersions(request);
        Console.WriteLine("List versions response: {0}", response.StatusCode);
        foreach (ObsObjectVersion objectVersion in response.Versions)
        {
            Console.WriteLine("Key: {0}", objectVersion.ObjectKey);
            Console.WriteLine("VersionId: {0}", objectVersion.VersionId);
        }
        request.KeyMarker = response.NextKeyMarker;
        request.VersionIdMarker = response.NextVersionIdMarker;
    }
    while (response.IsTruncated);
}
catch (ObsException ex)
{
    Console.WriteLine("ErrorCode: {0}", ex.ErrorCode);
    Console.WriteLine("ErrorMessage: {0}", ex.ErrorMessage);
}
