设置生命周期规则
您可以通过ObsClient.SetBucketLifecycle设置桶的生命周期规则。
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/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); }
设置对象过期时间
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过期时间:
// 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); // 设置对象过期时间 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; rule1.Expiration = new Expiration(); //指定满足前缀的对象创建60天后过期 rule1.Expiration.Days = 60; // 指定满足前缀的对象成为历史版本60天后过期 rule1.NoncurrentVersionExpiration = new NoncurrentVersionExpiration(); rule1.NoncurrentVersionExpiration.NoncurrentDays = 60; 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); }

- 调用设置生命周期规则后会将原有规则覆盖。
