PHP implements open source Baidu Cloud SDK

With the rapid development of Internet technology, cloud storage has become a very convenient way to store files. Users can access their data anytime and anywhere through any Internet-connected device. Among the many cloud storage services, Baidu Cloud is undoubtedly the leader. However, if you want to use Baidu Cloud Storage services in your own website or application, you need to use Baidu Cloud SDK, and most Baidu Cloud SDKs are based on Java or Python. So, in this article, I will introduce how to use PHP to implement the open source Baidu Cloud SDK.

1. Register for Baidu Cloud and apply for a developer account
If you do not have a Baidu Cloud developer account, you need to log in to the Baidu Cloud official website and complete the registration. After successful registration, you can get an AppKey and AppSecret. These two parameters can be used in subsequent development.

2. Download Baidu Cloud SDK
Download the PHP version of Baidu Cloud SDK through the official website or other channels. The latest version is currently 2.0.0, which can be downloaded from the Github repository https://github.com/todohuq/bce-sdk-php.

3. Create a BceClient object
Before using the Baidu Cloud Storage service, you need to create a BceClient object first, and then you can implement various operations by calling the object's methods. The code to create the BceClient object is as follows:

require_once 'BaiduBce.phar';
use BaiduBceBceClientConfiguration;
use BaiduBceExceptionBceClientException;
use BaiduBceServicesBosBosClient;

// 设置AK/SK
$config = [
    'credentials' => [
        'accessKeyId' => 'yourAccessKeyId',
        'secretAccessKey' => 'yourSecretAccessKey',
    ],
    'endpoint' => 'yourBosEndpoint',
];

// 实例化BosClient
try {
    $bosClient = new BosClient($config);
} catch (BceClientException $e) {
    die($e->getMessage());
}

You need to replace the parameters "yourAccessKeyId", "yourSecretAccessKey" and "yourBosEndpoint" with the corresponding information in your Baidu Cloud account.

4. Upload files to Baidu Cloud Storage
The code for uploading files to Baidu Cloud Storage is as follows:

$bucketName = 'yourBucketName';
$objectKey = 'yourObjectKey';
$filePath = 'yourFilePath';

// 上传文件到BOS
try {
    $bosClient->putObjectFromFile($bucketName, $objectKey, $filePath);
    echo "Upload file $filePath successfully.
";
} catch (BceClientException $e) {
    echo $e->getMessage() . "
";
}

You need to replace the parameters "yourBucketName", "yourObjectKey" and "yourFilePath" with own information.

5. Download files in Baidu Cloud Storage
The code to download files in Baidu Cloud Storage is as follows:

$bucketName = 'yourBucketName';
$objectKey = 'yourObjectKey';
$downloadPath = 'yourDownloadPath';
$options = [];

// 下载BOS存储桶的对象
try {
    $bosClient->getObjectToFile($bucketName, $objectKey, $downloadPath, $options);
    echo "Download file $downloadPath successfully.
";
} catch (BceClientException $e) {
    echo $e->getMessage() . "
";
}

You need to change the parameters "yourBucketName", "yourObjectKey" and "yourDownloadPath" Replace with your own information.

6. Delete files in Baidu Cloud Storage
The code to delete files in Baidu Cloud Storage is as follows:

$bucketName = 'yourBucketName';
$objectKey = 'yourObjectKey';

// 删除BOS存储桶指定的对象
try {
    $bosClient->deleteObject($bucketName, $objectKey);
    echo "Delete object $objectKey successfully.
";
} catch (BceClientException $e) {
    echo $e->getMessage() . "
";
}

You need to replace the parameters "yourBucketName" and "yourObjectKey" with your own information.

7. Summary
Through the introduction of the above code snippets, we can understand how to use PHP to implement the open source Baidu Cloud SDK. Before using Baidu Cloud services, you need to register a Baidu Cloud developer account and obtain the corresponding AppKey and AppSecret. In terms of code implementation, you need to create a BceClient object first, and then you can upload, download or delete files by calling the object's methods. With the continuous popularity of cloud storage, I believe that the demand for PHP to implement Baidu Cloud SDK will become higher and higher. By mastering this SDK, we can better cope with the actual needs in daily work.
