Object Storage Service:Manage logging using OSS SDK for PHP 1.0

Prerequisites

Before you begin, ensure that you have the following RAM permissions:

• oss:PutBucketLogging to enable logging

• oss:GetBucketLogging to query logging configuration

• oss:DeleteBucketLogging to disable logging

For details, see Attach a custom policy to a RAM user.

Usage notes

• The examples use the public endpoint for the China (Hangzhou) region. To access OSS from other Alibaba Cloud services in the same region, use an internal endpoint. For supported regions and endpoints, see Regions and endpoints.

• The examples initialize the OssClient instance using an OSS endpoint. For other initialization options, such as custom domains or Security Token Service (STS) credentials, see Create an OssClient instance.

Enable logging for a bucket

Call putBucketLogging with the source bucket name, destination bucket name, and an optional target prefix. If you omit the target prefix, log objects are stored in the root directory of the destination bucket.

Parameters

<?php
if (is_file(__DIR__ . '/../autoload.php')) {
    require_once __DIR__ . '/../autoload.php';
}
if (is_file(__DIR__ . '/../vendor/autoload.php')) {
    require_once __DIR__ . '/../vendor/autoload.php';
}

use OSS\Credentials\EnvironmentVariableCredentialsProvider;
use OSS\OssClient;
use OSS\CoreOssException;

// 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.
$provider = new EnvironmentVariableCredentialsProvider();
// 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.
$endpoint = "yourEndpoint";
// Specify the name of the source bucket for which you want to enable logging. Example: examplebucket.
$bucket= "examplebucket";

$option = array();
// Specify the name of the destination bucket in which the log objects are stored.
$targetBucket = "destbucket";
// Specify the directory in which the log objects are stored. 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.
$targetPrefix = "log/";

try {
    $config = array(
        "provider" => $provider,
        "endpoint" => $endpoint,
        "signatureVersion" => OssClient::OSS_SIGNATURE_VERSION_V4,
        "region"=> "cn-hangzhou"
    );
    $ossClient = new OssClient($config);

    // Enable logging for the source bucket.
    $ossClient->putBucketLogging($bucket, $targetBucket, $targetPrefix, $option);
} catch (OssException $e) {
    printf(__FUNCTION__ . ": FAILED\n");
    printf($e->getMessage() . "\n");
    return;
}
print(__FUNCTION__ . ": OK" . "\n");

Query the logging configuration of a bucket

Call getBucketLogging to retrieve the current logging configuration. The method returns a configuration object; call serializeToXml() to inspect it.

<?php
if (is_file(__DIR__ . '/../autoload.php')) {
    require_once __DIR__ . '/../autoload.php';
}
if (is_file(__DIR__ . '/../vendor/autoload.php')) {
    require_once __DIR__ . '/../vendor/autoload.php';
}

use OSS\Credentials\EnvironmentVariableCredentialsProvider;
use OSS\OssClient;
use OSS\CoreOssException;

// 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.
$provider = new EnvironmentVariableCredentialsProvider();
// 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.
$endpoint = "yourEndpoint";
// Specify the name of the bucket. Example: examplebucket.
$bucket= "examplebucket";

$loggingConfig = null;
$options = array();
try {
    $config = array(
        "provider" => $provider,
        "endpoint" => $endpoint,
        "signatureVersion" => OssClient::OSS_SIGNATURE_VERSION_V4,
        "region"=> "cn-hangzhou"
    );
    $ossClient = new OssClient($config);

    // Query the logging configurations of the bucket.
    $loggingConfig = $ossClient->getBucketLogging($bucket, $options);
} catch (OssException $e) {
    printf(__FUNCTION__ . ": FAILED\n");
    printf($e->getMessage() . "\n");
    return;
}
print(__FUNCTION__ . ": OK" . "\n");
print($loggingConfig->serializeToXml() . "\n");

Disable logging for a bucket

Call deleteBucketLogging with the bucket name. No additional parameters are required.

<?php
if (is_file(__DIR__ . '/../autoload.php')) {
    require_once __DIR__ . '/../autoload.php';
}
if (is_file(__DIR__ . '/../vendor/autoload.php')) {
    require_once __DIR__ . '/../vendor/autoload.php';
}

use OSS\Credentials\EnvironmentVariableCredentialsProvider;
use OSS\OssClient;
use OSS\CoreOssException;

// 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.
$provider = new EnvironmentVariableCredentialsProvider();
// 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.
$endpoint = "yourEndpoint";
// Specify the name of the bucket. Example: examplebucket.
$bucket= "examplebucket";

try {
    $config = array(
        "provider" => $provider,
        "endpoint" => $endpoint,
        "signatureVersion" => OssClient::OSS_SIGNATURE_VERSION_V4,
        "region"=> "cn-hangzhou"

    );
    $ossClient = new OssClient($config);

    // Disable logging for the bucket.
    $ossClient->deleteBucketLogging($bucket);
} catch (OssException $e) {
    printf(__FUNCTION__ . ": FAILED\n");
    printf($e->getMessage() . "\n");
    return;
}
print(__FUNCTION__ . ": OK" . "\n");
