您可以通过存储空间(Bucket)的标签功能, 对Bucket进行分类管理,如ListBucket时只显示带有指定标签的Bucket。

注意事项

使用Bucket标签功能时,有如下注意事项:

  • 只有Bucket的拥有者及授权的RAM用户才能为Bucket设置标签,否则返回403 Forbidden错误,错误码:AccessDenied。
  • 最多可设置20对Bucket标签(Key-Value对)。
    • Key最大长度为64字节,不能以http://https://Aliyun为前缀,且不能为空。
    • Value最大长度为128字节,允许为空。
    • Key和Value必须为UTF-8编码。
  • PutBucketTags是覆盖语义,即新设置的标签完全覆盖已有的标签。

设置Bucket标签

以下代码用于设置Bucket标签:

#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);

    /*设置Bucket标签*/
    SetBucketTaggingRequest request(BucketName);
    Tag tag1("yourTagkey1","yourTagValue1");
    Tag tag2("yourTagkey2", "yourTagValue2");
    TagSet tagset;
    tagset.push_back(tag1);
    tagset.push_back(tag2);
    Tagging taging;
    taging.setTags(tagset);
    request.setTagging(taging);
    auto outcome = client.SetBucketTagging(request);

    if (outcome.isSuccess()) {      
            std::cout << " SetBucketTagging success " << std::endl;
    }
    else {
        /*异常处理*/
        std::cout << "SetBucketTagging 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;
}

获取Bucket标签

以下代码用于获取Bucket标签:

#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);

    /*获取Bucket标签*/
    GetBucketTaggingRequest request(BucketName);
    auto outcome = client.GetBucketTagging(request);

    if (outcome.isSuccess()) {      
        std::cout << " GetBucketTagging success " << std::endl;
        for (const auto& tag : outcome.result().Tagging().Tags()) {
            std::cout << "tag key:" << tag.Key() <<
            "tag value:" << tag.Value() << std::endl; 
        }
    }
    else {
        /*异常处理*/
        std::cout << "GetBucketTagging 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;
}

列举带指定标签的Bucket

以下代码用于列举带指定标签的Bucket:

#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);

    /*列举带指定标签的Bucket*/
    ListBucketsRequest request;
    Tag tag1("yourTagkey1","yourTagValue1");

    request.setTag(tag1);
    auto outcome = client.ListBuckets(request);

    if (outcome.isSuccess()) {      
        std::cout << "ListBuckets success" << std::endl;
        for (const auto& bucket : outcome.result().Buckets()) {
            std::cout << "bucket name:" << bucket.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;
}
