管理存储空间访问权限（C++ SDK V2）

注意事项

• 运行示例代码前，请将代码中的 <region> 替换为实际的地域，如 cn-hangzhou。

• 本文示例代码使用环境变量获取访问凭证。

• 要设置存储空间ACL，您必须拥有 oss:PutBucketAcl 权限。要获取存储空间ACL，您必须拥有 oss:GetBucketAcl 权限。

Bucket ACL说明

设置存储空间ACL

以下代码演示如何设置存储空间的ACL：

#include <iostream>
#include "alibabacloud/oss2/ClientConfiguration.h"
#include "alibabacloud/oss2/OSSClient.h"
#include "alibabacloud/oss2/credentials/CredentialsProvider.h"

namespace oss = alibabacloud::oss2;

int main() {
    auto conf = oss::ClientConfiguration::loadDefault();
    conf.region = "<region>";
    conf.credentialsProvider = std::make_shared<oss::EnvironmentVariableCredentialsProvider>();

    oss::OSSClient client(conf);

    auto outcome = client.putBucketAcl(
        oss::models::PutBucketAclRequest()
            .setBucket("examplebucket")
            .setAcl("public-read"));

    if (!outcome.has_value()) {
        auto& e = outcome.error();
        std::cerr << "设置存储空间ACL失败"
                  << ", code: " << e.getCode()
                  << ", message: " << e.getMessage()
                  << ", requestId: " << e.getRequestId() << std::endl;
        return 1;
    }

    auto& result = outcome.value();
    std::cout << "设置存储空间ACL成功"
              << ", status: " << result.getStatusCode()
              << ", requestId: " << result.getRequestId() << std::endl;
    return 0;
}
        

获取存储空间ACL

以下代码演示如何获取存储空间的ACL：

#include <iostream>
#include "alibabacloud/oss2/ClientConfiguration.h"
#include "alibabacloud/oss2/OSSClient.h"
#include "alibabacloud/oss2/credentials/CredentialsProvider.h"

namespace oss = alibabacloud::oss2;

int main() {
    auto conf = oss::ClientConfiguration::loadDefault();
    conf.region = "<region>";
    conf.credentialsProvider = std::make_shared<oss::EnvironmentVariableCredentialsProvider>();

    oss::OSSClient client(conf);

    auto outcome = client.getBucketAcl(
        oss::models::GetBucketAclRequest()
            .setBucket("examplebucket"));

    if (!outcome.has_value()) {
        auto& e = outcome.error();
        std::cerr << "获取存储空间ACL失败"
                  << ", code: " << e.getCode()
                  << ", message: " << e.getMessage()
                  << ", requestId: " << e.getRequestId() << std::endl;
        return 1;
    }

    auto& result = outcome.value();
    auto& acp = result.getAccessControlPolicy();
    std::cout << "获取存储空间ACL成功"
              << ", status: " << result.getStatusCode() << std::endl;
    if (acp.owner) {
        std::cout << "Owner Id: " << acp.owner->id.value_or("") << std::endl;
    }
    if (acp.accessControlList) {
        std::cout << "ACL Grant: " << acp.accessControlList->grant.value_or("") << std::endl;
    }
    return 0;
}
