AWS getobject + 保存时设置权限

Question

我正在与 AWS PHP SDK V2.8 和 cakephp V2.3 合作 AWS EC2 Ubuntu machine。我正在尝试将对象从 AWS S3 下载到我的 AWS 服务器。它工作正常只是一个问题是我如何设置文件的权限 644 到 777。

这是我的代码。

        $saveAs = "/var/www/html/app/webroot/files/image/" . $result[$type][0]['id'] . "/" . $result[$type][0]['attachment'];
        $key = "files/image/" . $result[$type][0]['id'] . "/" . $result[$type][0]['attachment'];
        $result = $this->Amazon->S3->getObject(array(
            'Bucket' => 'mytest.sample',
            // 'Key' => 'avtar-auth_test_latest5.png',
            'Key' => $key,
            'version' => 'latest',
            'SaveAs' => $saveAs
        ));

我也试过了

   $saveAs = "/var/www/html/app/webroot/files/image/" . $result[$type][0]['id'] . "/" . $result[$type][0]['attachment'];
    $key = "files/image/" . $result[$type][0]['id'] . "/" . $result[$type][0]['attachment'];
    $result = $this->Amazon->S3->getObject(array(
        'Bucket' => 'mytest.sample',
        // 'Key' => 'avtar-auth_test_latest5.png',
        'Key' => $key,
        'version' => 'latest',
        'SaveAs' => chmod($saveAs,'0777')
    ));

Answer 1

不执行 chmod 函数并将其结果传递给 getObject 函数，而是在保存文件后使用单独的语句修改文件权限：

$saveAs = "/var/www/html/app/webroot/files/image/" . $result[$type][0]['id'] . "/" . $result[$type][0]['attachment'];
$key = "files/image/" . $result[$type][0]['id'] . "/" . $result[$type][0]['attachment'];
$result = $this->Amazon->S3->getObject(array(
    'Bucket' => 'mytest.sample',
    // 'Key' => 'avtar-auth_test_latest5.png',
    'Key' => $key,
    'version' => 'latest',
    'SaveAs' => $saveAs
));

chmod($saveAs,0777);
