如何使用PHP与又拍云API实现音视频的存储加密和访问权限控制的功能

<?php
require_once('vendor/autoload.php');

// 配置又拍云账号密钥和存储空间名称
$config = array(
    'service' => 'video-storage',
    'bucket' => 'your-bucket-name',
    'operator' => 'your-operator',
    'password' => 'your-password'
);

// 创建又拍云实例
$upyun = new UpyunUpyun($config['service'], $config['bucket'], $config['operator'], $config['password']);

// 要上传的文件路径
$file_path = 'path/to/your/video.mp4';

// 设置加密存储参数
$options = array(
    'encryption' => true
);

// 执行上传操作
$response = $upyun->writeFile('/path/to/your/video.mp4', file_get_contents($file_path), $options);

// 打印上传结果
var_dump($response);
?>

<?php
require_once('vendor/autoload.php');

// 配置又拍云账号密钥和存储空间名称
$config = array(
    'service' => 'video-storage',
    'bucket' => 'your-bucket-name',
    'operator' => 'your-operator',
    'password' => 'your-password'
);

// 创建又拍云实例
$upyun = new UpyunUpyun($config['service'], $config['bucket'], $config['operator'], $config['password']);

// 要获取访问密钥的文件路径
$file_path = '/path/to/your/video.mp4';

// 设置访问密钥参数
$options = array(
    'expiration' => time()+3600 // 设置密钥有效期为1小时
);

// 获取访问密钥
$signature = $upyun->getPolicyAndAuthorization($file_path, $options);

// 打印访问密钥
var_dump($signature);
?>
