如何测试oss php的功能

要测试OSS PHP的功能，您需要首先确保已经安装了PHP和相关的依赖库。然后，您可以按照以下步骤进行测试：

1. 导入必要的库和类：

require_once 'vendor/autoload.php';
use OSS\OssClient;
use OSS\Core\OssException;

2. 配置OSS客户端：

$accessKeyId = 'your_access_key_id';
$accessKeySecret = 'your_access_key_secret';
$endpoint = 'your_oss_endpoint'; // 例如：https://oss-cn-shanghai.aliyuncs.com
$client = new OssClient($accessKeyId, $accessKeySecret, $endpoint);

3. 上传文件：

$bucketName = 'your_bucket_name';
$filePath = 'path/to/your/local/file';
$objectKey = 'path/to/your/oss/object';

try {
    $result = $client->putObject($bucketName, $objectKey, $filePath);
    echo "Upload success: " . $result['ObjectURL'] . PHP_EOL;
} catch (OssException $e) {
    echo "Upload failed: " . $e->getMessage() . PHP_EOL;
}

4. 下载文件：

try {
    $result = $client->getObject($bucketName, $objectKey);
    file_put_contents('downloaded_file', $result['Body']->getContents());
    echo "Download success: downloaded_file" . PHP_EOL;
} catch (OssException $e) {
    echo "Download failed: " . $e->getMessage() . PHP_EOL;
}

5. 列出指定目录下的所有文件：

$delimiter = '';
$prefix = 'path/to/your/oss/directory/';

try {
    $result = $client->listObjects($bucketName, $delimiter, $prefix);
    foreach ($result['Contents'] as $file) {
        echo "File: " . $file['Key'] . PHP_EOL;
    }
} catch (OssException $e) {
    echo "List objects failed: " . $e->getMessage() . PHP_EOL;
}

6. 删除文件或目录：

$objectKey = 'path/to/your/oss/object';

try {
    $result = $client->deleteObject($bucketName, $objectKey);
    echo "Delete success" . PHP_EOL;
} catch (OssException $e) {
    echo "Delete failed: " . $e->getMessage() . PHP_EOL;
}

7. 判断文件是否存在：

$objectKey = 'path/to/your/oss/object';

try {
    $result = $client->headObject($bucketName, $objectKey);
    echo "File exists" . PHP_EOL;
} catch (OssException $e) {
    if ($e->getErrorCode() == '404') {
        echo "File not exists" . PHP_EOL;
    } else {
        echo "Error: " . $e->getMessage() . PHP_EOL;
    }
}

8. 获取文件元数据：

$objectKey = 'path/to/your/oss/object';

try {
    $result = $client->getObjectMetadata($bucketName, $objectKey);
    print_r($result);
} catch (OssException $e) {
    echo "Get object metadata failed: " . $e->getMessage() . PHP_EOL;
}

通过以上示例代码，您可以测试OSS PHP库的基本功能。如果需要更多信息，请参阅官方文档：https://help.aliyun.com/document_detail/31818.html
