Access Azure Blob Storage with PHP
PHP：7.2
Azure 本身有提供 azure-storage-php 這個 PHP Client Libraries 讓使用 PHP 的開發者可以操作 Azure Blob Storage。
azure-storage-php 裡面又細分成數個 repo，可以根據需要的操作功能做選擇，這篇就先以 azure-storage-blob: 1.5.2 當範例。
Installation
透過 composer 便可以安裝使用。
composer require microsoft/azure-storage-blob
Configuration
操作 Azure Blob Storage 需要兩種資訊，一個是 Storage Account 的 Connection String，另一個則是 Container Name。
Connection String，可以從 Storage Account 介面左邊的 存取金鑰（Access Keys） 看到。
require_once "vendor/autoload.php";
use MicrosoftAzure\Storage\Blob\BlobRestProxy;
$connectionString = 'DefaultEndpointsProtocol=https;AccountName=XXXXXX;AccountKey=XXXXXX;EndpointSuffix=core.windows.net';
$blobClient = BlobRestProxy::createBlobService($connectionString);
// Container Name
$myContainer = 'XXXXXXX';
Basic Usage
上傳檔案
use MicrosoftAzure\Storage\Common\Exceptions\ServiceException;
$content = fopen('4710765081331-1.xml', 'r');
// Virtual Hierarchy
$blobName = 'company/4710765081331-1.xml';
try {
// Upload blob
$blobClient->createBlockBlob($myContainer, $blobName, $content);
} catch (ServiceException $e) {
$code = $e->getCode();
$errorMessage = $e->getMessage();
echo $code . ': ' . $errorMessage . PHP_EOL;
}
下載檔案
use MicrosoftAzure\Storage\Common\Exceptions\ServiceException;
try {
// Download blob
$getBlobResult = $blobClient->getBlob($myContainer, 'xx.png');
} catch (ServiceException $e) {
$code = $e->getCode();
$errorMessage = $e->getMessage();
echo $code . ': ' . $errorMessage . PHP_EOL;
}
file_put_contents("xx.png", $getBlobResult->getContentStream());
建立 Container
use MicrosoftAzure\Storage\Blob\Models\CreateContainerOptions;
use MicrosoftAzure\Storage\Blob\Models\PublicAccessType;
use MicrosoftAzure\Storage\Common\Exceptions\ServiceException;
$createContainerOptions = new CreateContainerOptions();
// 設定 Public Access 權限
$createContainerOptions->setPublicAccess(PublicAccessType::CONTAINER_AND_BLOBS);
// 設定 Metadata
$createContainerOptions->addMetaData("key1", "value1");
try {
// Create Container
$blobClient->createContainer($myContainer, $createContainerOptions);
} catch (ServiceException $e) {
$code = $e->getCode();
$errorMessage = $e->getMessage();
echo $code . ': ' . $errorMessage . PHP_EOL;
}
取得 Container Property
$properties = $blobClient->getContainerProperties($myContainer);
echo 'Last modified: ' . $properties->getLastModified()->format('Y-m-d H:i:s') . PHP_EOL;
echo 'ETAG: ' . $properties->getETag() . PHP_EOL;
