如何通過C++SDK實現Bucket的標籤管理 - Object Storage Service

您可以通過標籤（Tags）標記不同用途的儲存空間（Bucket），並對Bucket進行分類管理。

注意事項

本文以華東1（杭州）外網Endpoint為例。如果您希望通過與OSS同地區的其他阿里雲產品訪問OSS，請使用內網Endpoint。關於OSS支援的Region與Endpoint的對應關係，請參見訪問網域名稱和資料中心。
本文以OSS網域名稱建立OSSClient為例。如果您希望通過自訂網域名、STS等方式建立OSSClient，請參見建立OssClient。
只有Bucket擁有者及授予oss:PutBucketTagging許可權的使用者才能為Bucket設定標籤，否則返回403 Forbidden錯誤，錯誤碼為AccessDenied。
每個Bucket最多可設定20個標籤（Key-Value對）。
Key和Value必須為UTF-8編碼。
Key最大長度為64字元，區分大小寫，不可為空。Key不支援以http://、https://、Aliyun為首碼（不區分大小寫）。
Value最大長度為128字元，可以為空白。

設定Bucket標籤

以下代碼用於為examplebucket儲存空間設定標籤。

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

int main(void)
{
    /*初始化OSS帳號資訊。*/
    
    /*yourEndpoint填寫Bucket所在地區對應的Endpoint。以華東1（杭州）為例，Endpoint填寫為https://oss-cn-hangzhou.aliyuncs.com。*/
    std::string Endpoint = "yourEndpoint";
    /*填寫Bucket名稱，例如examplebucket。*/
    std::string BucketName = "examplebucket";

    /*初始化網路等資源。*/
    InitializeSdk();

    ClientConfiguration conf;
    /* 從環境變數中擷取訪問憑證。運行本程式碼範例之前，請確保已設定環境變數OSS_ACCESS_KEY_ID和OSS_ACCESS_KEY_SECRET。*/
    auto credentialsProvider = std::make_shared<EnvironmentVariableCredentialsProvider>();
    OssClient client(Endpoint, credentialsProvider, conf);

    /*設定Bucket標籤。*/
    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 {
        /*異常處理。*/
        std::cout << "SetBucketTagging fail" <<
        ",code:" << outcome.error().Code() <<
        ",message:" << outcome.error().Message() <<
        ",requestId:" << outcome.error().RequestId() << std::endl;
        return -1;
    }

    /*釋放網路等資源。*/
    ShutdownSdk();
    return 0;
}

擷取Bucket標籤

以下代碼用於擷取examplebucket儲存空間的標籤。

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

int main(void)
{
    /*初始化OSS帳號資訊。*/
    
    /*yourEndpoint填寫Bucket所在地區對應的Endpoint。以華東1（杭州）為例，Endpoint填寫為https://oss-cn-hangzhou.aliyuncs.com。*/
    std::string Endpoint = "yourEndpoint";
    /*填寫Bucket名稱，例如examplebucket。*/
    std::string BucketName = "examplebucket";

    /*初始化網路等資源。*/
    InitializeSdk();

    ClientConfiguration conf;
    /* 從環境變數中擷取訪問憑證。運行本程式碼範例之前，請確保已設定環境變數OSS_ACCESS_KEY_ID和OSS_ACCESS_KEY_SECRET。*/
    auto credentialsProvider = std::make_shared<EnvironmentVariableCredentialsProvider>();
    OssClient client(Endpoint, credentialsProvider, conf);

    /*擷取Bucket標籤。*/
    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 {
        /*異常處理。*/
        std::cout << "GetBucketTagging fail" <<
        ",code:" << outcome.error().Code() <<
        ",message:" << outcome.error().Message() <<
        ",requestId:" << outcome.error().RequestId() << std::endl;
        return -1;
    }

    /*釋放網路等資源。*/
    ShutdownSdk();
    return 0;
}

列舉帶指定標籤的Bucket

以下代碼用於列舉帶指定標籤的Bucket。

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

int main(void)
{
    /*初始化OSS帳號資訊。*/
    
    /*yourEndpoint填寫Bucket所在地區對應的Endpoint。以華東1（杭州）為例，Endpoint填寫為https://oss-cn-hangzhou.aliyuncs.com。*/
    std::string Endpoint = "yourEndpoint";  

    /*初始化網路等資源。*/
    InitializeSdk();

    ClientConfiguration conf;
    /* 從環境變數中擷取訪問憑證。運行本程式碼範例之前，請確保已設定環境變數OSS_ACCESS_KEY_ID和OSS_ACCESS_KEY_SECRET。*/
    auto credentialsProvider = std::make_shared<EnvironmentVariableCredentialsProvider>();
    OssClient client(Endpoint, credentialsProvider, conf);

    /*列舉帶指定標籤的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 {
        /*異常處理。*/
        std::cout << "ListBuckets fail" <<
        ",code:" << outcome.error().Code() <<
        ",message:" << outcome.error().Message() <<
        ",requestId:" << outcome.error().RequestId() << std::endl;
        return -1;
    }

    /*釋放網路等資源。*/
    ShutdownSdk();
    return 0;
}

以下代碼用於刪除Buckey的所有標籤：

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

int main(void)
