ロギング - Object Storage Service - Alibaba Cloud ドキュメントセンター

Object Storage Service (OSS) は、OSSバケットに保存されているリソースへのアクセスを記録するためのアクセスログを生成します。バケットのロギングを有効にして設定すると、事前定義された命名規則に基づいて1時間ごとにアクセスログが生成され、ログが特定のバケットに保存されます。

使用上の注意

このトピックでは、中国 (杭州) リージョンのパブリックエンドポイントを使用します。 OSSと同じリージョンにある他のAlibaba CloudサービスからOSSにアクセスする場合は、内部エンドポイントを使用します。 OSSリージョンとエンドポイントの詳細については、「OSSリージョンとエンドポイント」をご参照ください。
このトピックでは、OSSエンドポイントを使用してOSSClientインスタンスを作成します。カスタムドメイン名またはSecurity Token Service (STS) を使用してOSSClientを作成する場合は、「OSSClientインスタンスの作成」をご参照ください。
ロギングを有効にするには、oss:PutBucketLogging権限が必要です。ログ設定をクエリするには、oss:GetBucketLogging権限が必要です。ロギングを無効にするには、oss:DeleteBucketLogging権限が必要です。詳細については、「RAMポリシーの一般的な例」をご参照ください。

バケットのロギングの有効化

次のサンプルコードは、バケットのロギングを有効にする方法の例を示しています。

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

int main(void)
{
    /* Initialize information about the account that is used to access OSS. */
            
    /* Specify the endpoint of the region in which the bucket is located. For example, if the bucket is located in the China (Hangzhou) region, set the endpoint to https://oss-cn-hangzhou.aliyuncs.com. */
    std::string Endpoint = "yourEndpoint";
    /* Specify the region in which the bucket is located. For example, if the bucket is located in the China (Hangzhou) region, set the region to cn-hangzhou. */
    std::string Region = "yourRegion";
    /* Specify the name of the source bucket for which you want to enable logging. Example: examplebucket. */
    std::string BucketName = "examplebucket";
    /* Specify the name of the destination bucket in which the log objects are stored. The source bucket and the destination bucket can be the same bucket or different buckets. */
    std::string TargetBucketName = "destbucket";
    /* Set the directory in which the log objects are stored to log/. If you specify this parameter, the log objects are stored in the specified directory of the destination bucket. If you do not specify this parameter, the log objects are stored in the root directory of the destination bucket. */
    std::string TargetPrefix  ="log/";

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

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

    /* Enable logging for the bucket. */
    SetBucketLoggingRequest request(BucketName, TargetBucketName, TargetPrefix);
    auto outcome = client.SetBucketLogging(request);

    if (!outcome.isSuccess()) {
        /* Handle exceptions. */
        std::cout << "SetBucketLogging fail" <<
        ",code:" << outcome.error().Code() <<
        ",message:" << outcome.error().Message() <<
        ",requestId:" << outcome.error().RequestId() << std::endl;
        return -1;
    }

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

バケットのログ設定の照会

次のサンプルコードは、バケットのログ設定を照会する方法の例を示しています。

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

int main(void)
{
    /* Initialize information about the account that is used to access OSS. */
            
    /* Specify the endpoint of the region in which the bucket is located. For example, if the bucket is located in the China (Hangzhou) region, set the endpoint to https://oss-cn-hangzhou.aliyuncs.com. */
    std::string Endpoint = "yourEndpoint";
    /* Specify the region in which the bucket is located. For example, if the bucket is located in the China (Hangzhou) region, set the region to cn-hangzhou. */
    std::string Region = "yourRegion";
    /* Specify the name of the bucket. Example: examplebucket. */
    std::string BucketName = "examplebucket";

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

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

    /* View the logging configurations of the bucket. */
    GetBucketLoggingRequest request(BucketName);
    auto outcome = client.GetBucketLogging(request);

    if (outcome.isSuccess()) {
        std::cout <<" GetBucketLogging success, TargetBucket: " << outcome.result().TargetBucket() << 
        ",TargetPrefix: " << outcome.result().TargetPrefix() << std::endl;
    }
    else { 
        /* Handle exceptions. */
        std::cout << "GetBucketLogging fail" <<
        ",code:" << outcome.error().Code() <<
        ",message:" << outcome.error().Message() <<
        ",requestId:" << outcome.error().RequestId() << std::endl;
        return -1;
    }

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