How to use PHP to implement OSS cloud storage

In recent years, cloud storage has become more and more widely used, and Alibaba Cloud's OSS cloud storage service has also occupied a place in the domestic market. On this basis, this article will share how to use PHP to implement OSS cloud storage.

First, we need to register an account on the Alibaba Cloud official website and create an OSS storage space. The creation steps are described in detail in the official documentation and will not be repeated here.

Next, we need to install the OSS SDK for PHP provided by Alibaba Cloud. Use the following command in the terminal to install:

composer require aliyuncs/oss-sdk-php

After the installation is complete, we can connect and set up the OSS client through the following code:

use OSSOssClient;
use OSSCoreOssException;

$accessKeyId = '<Your AccessKeyId>';
$accessKeySecret = '<Your AccessKeySecret>';
$endpoint = '<Your endpoint>';
$bucket = '<Your bucket name>';

try {
    //创建OSS客户端连接
    $ossClient = new OssClient($accessKeyId, $accessKeySecret, $endpoint);
    //设置存储空间默认ACL设置为私有
    $ossClient->putBucketAcl($bucket, OssClient::OSS_ACL_TYPE_PRIVATE);
} catch (OssException $e) {
    //连接失败处理
}

Among them, $accessKeyId and $accessKeySecret are the AccessKey ID and AccessKey Secret obtained through the Alibaba Cloud official website, $endpoint is the access domain name of the OSS service, and $bucket is the created storage space name.

Next, we can upload and delete files through the following code:

$file = '<Your local file path>';
$object = '<Your object name>';

try {
    //上传文件到指定的存储空间中
    $ossClient->uploadFile($bucket, $object, $file);
    //删除存储空间中的指定文件
    $ossClient->deleteObject($bucket, $object);
} catch (OssException $e) {
    //处理上传或删除文件失败的情况
}

Among them, $file is the local file path that needs to be uploaded, $object is the name of the object stored in OSS. We can also download files through the following code:

$localFile = '<Your local file path>';

try {
    //从存储空间中下载指定名称的文件到指定本地路径
    $ossClient->getObject($bucket, $object, ['fileDownload' => $localFile]);
} catch (OssException $e) {
    //处理下载文件失败的情况
}

When uploading and downloading files, we can set some optional parameters, such as the file's ACL, Content-Type, etc. Specific parameters can be found in the official documentation.

Finally, when we do not need to use the OSS client, we can close and clean up the client through the following code:

try {
    //断开OSS客户端连接并清理客户端实例
    $ossClient->close();
} catch (OssException $e) {
    //处理断开OSS客户端连接失败的情况
}

The above is the basic process of using PHP to implement OSS cloud storage. Through these codes, we can easily implement functions such as file upload, download, and deletion in OSS storage space. In practical applications, we can also perform parameter settings and function expansion according to our own needs.
