How to list all buckets under the current account-Object Storage Service(OSS)-阿里云帮助中心

This topic describes how to list all the buckets in your account. The buckets are listed in alphabetical order.

Notes

In this topic, the public endpoint of the China (Hangzhou) region is used. If you want to access OSS from other Alibaba Cloud services in the same region as OSS, use an internal endpoint. For more information about OSS regions and endpoints, see Regions and endpoints.
This topic demonstrates creating an OSSClient instance with an OSS endpoint. For alternative configurations, such as using a custom domain or authenticating with credentials from Security Token Service (STS), see Create an OssClient instance.
To list buckets, you must have the oss:ListBuckets permission. For more information, see Grant a custom policy.

Sample code

The following code provides an example of how to list all the buckets in your account.

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

int main(void)
{
    /* Initialize the OSS account information. */
    
    /* Set yourEndpoint to the endpoint of the region where the bucket is located. For example, if the bucket is in the China (Hangzhou) region, set the endpoint to https://oss-cn-hangzhou.aliyuncs.com. */
    std::string Endpoint = "yourEndpoint";
    
    /* Set yourRegion to the region where the bucket is located. For example, if the bucket is in the China (Hangzhou) region, set the region to cn-hangzhou. */
    std::string Region = "yourRegion";

    /* Initialize network resources. */
    InitializeSdk();

    ClientConfiguration conf;
    conf.signatureVersion = SignatureVersionType::V4;
    /* Obtain access credentials from environment variables. Before you run this sample code, make sure that the OSS_ACCESS_KEY_ID and OSS_ACCESS_KEY_SECRET environment variables are set. */
    auto credentialsProvider = std::make_shared<EnvironmentVariableCredentialsProvider>();
    OssClient client(Endpoint, credentialsProvider, conf);
    client.SetRegion(Region);

    /* List all buckets under the current account. */
    ListBucketsRequest request;
    auto outcome = client.ListBuckets(request);

    if (outcome.isSuccess()) {
        /* Print bucket information. */
        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 {
        /* Handle the exception. */
        std::cout << "ListBuckets fail" <<
        ",code:" << outcome.error().Code() <<
        ",message:" << outcome.error().Message() <<
        ",requestId:" << outcome.error().RequestId() << std::endl;
        return -1;
    }

    /* Release network resources. */
    ShutdownSdk();
    return 0;
}
