Object Storage Service:Get object tags (C++ SDK)

O código a seguir mostra como obter as informações de tags de objeto:

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

int main(void)
{
    /* Initialize OSS account information. */
            
   /* Set yourEndpoint to the endpoint of the region where the bucket is located. For example, for 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, for the China (Hangzhou) region, set the region to cn-hangzhou. */
    std::string Region = "yourRegion";
    /* Specify the bucket name. For example, examplebucket. */
    std::string BucketName = "examplebucket";
    /* Specify the full path of the object. The full path cannot include the bucket name. For example, exampledir/exampleobject.txt. */
    std::string ObjectName = "exampledir/exampleobject.txt";

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

    ClientConfiguration conf;
    conf.signatureVersion = SignatureVersionType::V4;
    /* Obtain access credentials from environment variables. Before running 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);
    std::shared_ptr<std::iostream> content = std::make_shared<std::stringstream>();
    *content << "test cpp sdk";
    PutObjectRequest request(BucketName, ObjectName, content);

    /* Upload the file. */
    auto outcome = client.PutObject(request);

    /* Set object tags. */
    Tagging tagging;
    tagging.addTag(Tag("key1", "value1"));
    tagging.addTag(Tag("key2", "value2"));
    auto putTaggingOutcome = client.SetObjectTagging(SetObjectTaggingRequest(BucketName, ObjectName, tagging));

    /* Get object tags. */
    auto getTaggingOutcome = client.GetObjectTagging(GetObjectTaggingRequest(BucketName, ObjectName));

    if (!getTaggingOutcome.isSuccess()) {
        /* Handle exceptions. */
        std::cout << "getTaggingOutcome fail" <<
        ",code:" << getTaggingOutcome.error().Code() <<
        ",message:" << getTaggingOutcome.error().Message() <<
        ",requestId:" << getTaggingOutcome.error().RequestId() << std::endl;
        return -1;
    }
    else {
        auto taglist = getTaggingOutcome.result().Tagging();
        for (const auto& tag : taglist.Tags())
        {
          std::cout <<"GetObjectTagging success, Key:" 
          << tag.Key() << "; Value:" << tag.Value() << std::endl;
        }
    }

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