管理桶策略

开发过程中,您有任何问题可以在github上提交issue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/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);
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/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);
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/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);
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);
}
