2.1 Log in to Qiniu Cloud Console

Log in to Qiniu Cloud Console with the registered Qiniu Cloud account, click "Personal Center", and select "Key Management" from the left menu .

2.2 Obtain AccessKey and SecretKey

On the secret key management page, we can see AccessKey and SecretKey. These two keys are used for authentication and authorization, so be sure to keep them in a safe place.

3: Install Qiniu Cloud PHP SDK

To use Qiniu Cloud Storage in PHP, you need to install the SDK first. Qiniuyun PHP SDK can be installed through Composer.

Enter the following command in the command line window:

composer require qiniu/php-sdk

Four: Upload files to Qiniu Cloud Storage

Get the AccessKey and SecretKey of Qiniu Cloud Storage and install it After installing the SDK, we can use PHP to upload files to Qiniu Cloud Storage.

require_once DIR . '/vendor/autoload.php';

$accessKey = 'ACCESS_KEY';
$secretKey = 'SECRET_KEY';
$bucket = 'BUCKET_NAME';
$filePath = '/path/to/local/file';
$key = 'remote_file_name';

// Construct authentication object
$auth = new \Qiniu\Auth($accessKey, $secretKey);

// Generate upload Token
$token = $auth->uploadToken($ bucket);

// Initialize the UploadManager object and upload files.
$uploadMgr = new \Qiniu\Storage\UploadManager();
list($ret, $err) = $uploadMgr->putFile($token, $key, $filePath);

echo "\n====> putFile result: \n";
if ($err !== null) {

 var_dump($err);

} else {

 var_dump($ret);

}

?>

It should be noted that before using the above code, you need to replace the $accessKey, $secretKey, $bucket, $filePath, $key and other parameters.

5: Get the list of uploaded files

Through the above method, we can upload local files to Qiniu Cloud Storage. As files are uploaded, we may need to get a list of files that have been uploaded. This can be achieved through Qiniu Cloud’s SDK. The following is the code to get a list of all files in a specified space.

require_once DIR . '/vendor/autoload.php';

$accessKey = 'ACCESS_KEY';
$secretKey = 'SECRET_KEY';
$bucket = 'BUCKET_NAME';

$config = new \Qiniu\Config();
$config->useHTTPS = true;
/ / Manage credentials
$auth = new \Qiniu\Auth($accessKey, $secretKey);
// Build Qiniu cloud storage object
$client = new \Qiniu\Storage\BucketManager($auth, $config);
// File prefix
$prefix = '';
// List files
list($items, $marker, $err) = $client->listFiles($ bucket, $prefix);

if ($err !== null) {

echo "\n====> list file err: \n";
var_dump($err);

} else {

echo "\n====> list file result: \n";
var_dump($items);

}

?>
