    Object Storage Service:Almacenamiento de registros (C# SDK V1)

    Última actualización: Sep 02, 2026

    El registro de acceso de Object Storage Service (OSS) captura información detallada sobre las solicitudes realizadas a sus buckets. Una vez que habilita el registro para un bucket de origen, OSS genera y entrega automáticamente archivos de registro cada hora en un bucket de destino que usted especifique, mediante una convención de nombres predefinida.

    Notas

    • En este tema se utiliza el endpoint público de la región China (Hangzhou). Si desea acceder a OSS desde otros servicios de Alibaba Cloud en la misma región que OSS, utilice un endpoint interno. Para obtener más información sobre las regiones y endpoints de OSS, consulte Regions and endpoints.

    • Este tema muestra cómo crear una instancia de OSSClient con un endpoint de OSS. Para configuraciones alternativas, como el uso de un dominio personalizado o la autenticación con credenciales de Security Token Service (STS), consulte Initialization (C# SDK V1).

    • La gestión del registro de un bucket requiere permisos específicos: oss:PutBucketLogging para habilitarlo, oss:GetBucketLogging para consultarlo y oss:DeleteBucketLogging para deshabilitarlo. Para obtener más información, consulte Grant a custom policy.

    Habilitar el registro de un bucket

    A continuación se muestra un ejemplo de código para habilitar el registro de un bucket:

    using Aliyun.OSS;
using Aliyun.OSS.Common;

// Set the Endpoint. This example uses https://oss-cn-hangzhou.aliyuncs.com, the public Endpoint for the China (Hangzhou) region. For other regions, set the Endpoint to the actual value.
var endpoint = "https://oss-cn-hangzhou.aliyuncs.com";
// 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 configured.
var accessKeyId = Environment.GetEnvironmentVariable("OSS_ACCESS_KEY_ID");
var accessKeySecret = Environment.GetEnvironmentVariable("OSS_ACCESS_KEY_SECRET");
// Set the name of the bucket for which to enable log storage, for example, examplebucket.
var bucketName = "examplebucket";
// Set the destination bucket to store the log files. The destination bucket can be the same as or different from the source bucket.
var targetBucketName = "destbucket";
// Set the region where the bucket is located. This example uses cn-hangzhou, which is the ID of the China (Hangzhou) region.
const string region = "cn-hangzhou";

// Create a ClientConfiguration instance and modify the default parameters as needed.
var conf = new ClientConfiguration();

// Use Signature Version 4.
conf.SignatureVersion = SignatureVersion.V4;

// Create an OssClient instance.
var client = new OssClient(endpoint, accessKeyId, accessKeySecret, conf);
client.SetRegion(region);
try
{
    // Set the folder where the log files are stored to log/. If you specify this folder, the log files are saved to the specified folder in the destination bucket. If you do not specify this folder, the log files are saved to the root directory of the destination bucket.
    var request = new SetBucketLoggingRequest(bucketName, targetBucketName, "log/");
    // Enable the log storage feature.
    client.SetBucketLogging(request);
    Console.WriteLine("Set bucket:{0} Logging succeeded ", bucketName);
}
catch (OssException ex)
{
    Console.WriteLine("Failed with error code: {0}. Error message: {1}. \nRequestID:{2}\tHostID:{3}",
        ex.ErrorCode, ex.Message, ex.RequestId, ex.HostId);
}
catch (Exception ex)
{
    Console.WriteLine("Failed with error message: {0}", ex.Message);
}

    Consultar la configuración de registro de un bucket

    A continuación se muestra un ejemplo de código para consultar la configuración de registro de un bucket:

    using Aliyun.OSS;
using Aliyun.OSS.Common;
// Set the Endpoint. This example uses https://oss-cn-hangzhou.aliyuncs.com, the public Endpoint for the China (Hangzhou) region. For other regions, set the Endpoint to the actual value.
var endpoint = "https://oss-cn-hangzhou.aliyuncs.com";
// 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 configured.
var accessKeyId = Environment.GetEnvironmentVariable("OSS_ACCESS_KEY_ID");
var accessKeySecret = Environment.GetEnvironmentVariable("OSS_ACCESS_KEY_SECRET");
// Set the bucket name, for example, examplebucket.
var bucketName = "examplebucket";
// Set the region where the bucket is located. This example uses cn-hangzhou, which is the ID of the China (Hangzhou) region.
const string region = "cn-hangzhou";

// Create a ClientConfiguration instance and modify the default parameters as needed.
var conf = new ClientConfiguration();

// Use Signature Version 4.
conf.SignatureVersion = SignatureVersion.V4;

// Create an OssClient instance.
var client = new OssClient(endpoint, accessKeyId, accessKeySecret, conf);
client.SetRegion(region);
try
{
    // View the log storage configuration.
    var result = client.GetBucketLogging(bucketName);
    Console.WriteLine("Get bucket:{0} Logging succeeded, prefix:{1}", bucketName, result.TargetPrefix);
}
catch (OssException ex)
{
    Console.WriteLine("Failed with error code: {0}. Error message: {1}. \nRequestID:{2}\tHostID:{3}",
        ex.ErrorCode, ex.Message, ex.RequestId, ex.HostId);
}
catch (Exception ex)
{
    Console.WriteLine("Failed with error message: {0}", ex.Message);
}

    Deshabilitar el registro de un bucket

    A continuación se muestra un ejemplo de código para deshabilitar el registro de un bucket:

    using Aliyun.OSS;
using Aliyun.OSS.Common;
// Set the Endpoint. This example uses https://oss-cn-hangzhou.aliyuncs.com, the public Endpoint for the China (Hangzhou) region. For other regions, set the Endpoint to the actual value.
var endpoint = "https://oss-cn-hangzhou.aliyuncs.com";
// 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 configured.
var accessKeyId = Environment.GetEnvironmentVariable("OSS_ACCESS_KEY_ID");
var accessKeySecret = Environment.GetEnvironmentVariable("OSS_ACCESS_KEY_SECRET");
// Set the bucket name, for example, examplebucket.
var bucketName = "examplebucket";
// Set the region where the bucket is located. This example uses cn-hangzhou, which is the ID of the China (Hangzhou) region.
const string region = "cn-hangzhou";

// Create a ClientConfiguration instance and modify the default parameters as needed.
var conf = new ClientConfiguration();

// Use Signature Version 4.
conf.SignatureVersion = SignatureVersion.V4;

// Create an OssClient instance.
var client = new OssClient(endpoint, accessKeyId, accessKeySecret, conf);
client.SetRegion(region);
try
{
    // Disable the log storage feature.
    client.DeleteBucketLogging(bucketName);
    Console.WriteLine("Delete bucket:{0} Logging succeeded ", bucketName);
}
catch (OssException ex)
{
    Console.WriteLine("Failed with error code: {0}. Error message: {1}. \nRequestID:{2}\tHostID:{3}",
        ex.ErrorCode, ex.Message, ex.RequestId, ex.HostId);
}
catch (Exception ex)
{
    Console.WriteLine("Failed with error message: {0}", ex.Message);
}
