存储空间（Bucket）是存储对象（Object）的容器。对象都隶属于存储空间。本文介绍如何列举存储空间。

以下代码用于列举所有的存储空间：

#include <alibabacloud/oss/OssClient.h>
using namespace AlibabaCloud::OSS;

int main(void)
{
    /* 初始化OSS账号信息 */
    std::string AccessKeyId = "yourAccessKeyId";
    std::string AccessKeySecret = "yourAccessKeySecret";
    std::string Endpoint = "yourEndpoint";

    /* 初始化网络等资源 */
    InitializeSdk();

    ClientConfiguration conf;
    OssClient client(Endpoint, AccessKeyId, AccessKeySecret, conf);

    /* 列举存储空间 */
    ListBucketsRequest request;
    auto outcome = client.ListBuckets(request);

    if (outcome.isSuccess()) {
        /* 打印存储空间信息 */
        std::cout <<" success, and bucket count is" << outcome.result().Buckets().size() << std::endl;
        std::cout << "Bucket name is" << std::endl;
        for (auto result : outcome.result().Buckets())
        {
            std::cout << result.Name() << std::endl;
        }
    }
    else {
        /* 异常处理 */
        std::cout << "ListBuckets fail" <<
        ",code:" << outcome.error().Code() <<
        ",message:" << outcome.error().Message() <<
        ",requestId:" << outcome.error().RequestId() << std::endl;
        ShutdownSdk();
        return -1;
    }

    /* 释放网络等资源 */
    ShutdownSdk();
    return 0;
}
