管理桶策略

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。
除了桶访问权限外,桶的拥有者还可以通过桶策略,提供对桶和桶内对象的集中访问控制。
更多关于桶策略的内容请参考桶策略。
设置桶策略
您可以通过ObsClient.SetBucketPolicy设置桶策略。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); try { SetBucketPolicyRequest request = new SetBucketPolicyRequest { BucketName = "bucketname", Policy = "your policy", }; SetBucketPolicyResponse response = client.SetBucketPolicy(request); Console.WriteLine("Set bucket policy response: {0}", response.StatusCode); } catch (ObsException ex) { Console.WriteLine("ErrorCode: {0}", ex.ErrorCode); Console.WriteLine("ErrorMessage: {0}", ex.ErrorMessage); }

桶策略内容的具体格式(JSON格式字符串)请参考《对象存储服务API参考》。
获取桶策略
您可以通过ObsClient.GetBucketPolicy获取桶策略。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); try { GetBucketPolicyRequest request = new GetBucketPolicyRequest { BucketName = "bucketname", }; GetBucketPolicyResponse response = client.GetBucketPolicy(request); Console.WriteLine("Get bucket policy response: {0}", response.StatusCode); Console.WriteLine("Policy: {0}", response.Policy); } catch (ObsException ex) { Console.WriteLine("ErrorCode: {0}", ex.ErrorCode); Console.WriteLine("ErrorMessage: {0}", ex.ErrorMessage); }
删除桶策略
您可以通过ObsClient.DeleteBucketPolicy删除桶策略。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); try { DeleteBucketPolicyRequest request = new DeleteBucketPolicyRequest { BucketName = "bucketname", }; DeleteBucketPolicyResponse response = client.DeleteBucketPolicy(request); Console.WriteLine("Delete bucket policy response: {0}", response.StatusCode); } catch (ObsException ex) { Console.WriteLine("ErrorCode: {0}", ex.ErrorCode); Console.WriteLine("ErrorMessage: {0}", ex.ErrorMessage); }
