设置对象转换策略

以下代码展示了如何设置最新版本对象和历史版本对象的转换策略：

// 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);
//设置对象转换策略
try
{
    SetBucketLifecycleRequest request = new SetBucketLifecycleRequest();
    request.BucketName = "bucketname";
    request.Configuration = new LifecycleConfiguration();
    LifecycleRule rule1 = new LifecycleRule();
    rule1.Id = "rule1";
    rule1.Prefix = "prefix";
    rule1.Status = RuleStatusEnum.Enabled;
    Transition transition = new Transition();
    rule1.Transitions.Add(transition);     
    // 指定满足前缀的对象创建30天后转换
    transition.Days = 30;
    // 指定对象转换后的存储类型
    transition.StorageClass = StorageClassEnum.Warm;
    NoncurrentVersionTransition noncurrentVersionTransition  = new NoncurrentVersionTransition();
    rule1.NoncurrentVersionTransitions.Add(noncurrentVersionTransition);
    // 指定满足前缀的对象成为历史版本60天后转换
    noncurrentVersionTransition.NoncurrentDays = 60;
    // 指定历史版本对象转换后的存储类型
    noncurrentVersionTransition.StorageClass = StorageClassEnum.Warm;
    request.Configuration.Rules.Add(rule1);
    SetBucketLifecycleResponse response = client.SetBucketLifecycle(request);
    Console.WriteLine("Set bucket lifecycle response: {0}", response.StatusCode);
}
catch (ObsException ex)
{
    Console.WriteLine("ErrorCode: {0}", ex.ErrorCode);
    Console.WriteLine("ErrorMessage: {0}", ex.ErrorMessage);
}
