存储空间（Bucket）是存储对象（Object）的容器。对象都隶属于存储空间。本文介绍如何判断存储空间是否存在。

#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";
    std::string BucketName = "yourBucketName";

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

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

    /* 判断存储空间是否存在 */
    auto outcome = client.DoesBucketExist(BucketName);

    if (outcome) {    
        std::cout << " The Bucket exists" << std::endl;
    }
    else {
        std::cout << "The Bucket does not exist" << std::endl;
    }

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