Zend框架亚马逊S3 - 如何将文件存储为减少冗余?

标签: php zend-framework amazon-s3

zend框架为amazon S3 api提供了一个php包装器,简化了低级REST功能。

http://framework.zend.com/manual/en/zend.service.amazon.s3.html

例如,要在s3中存储文件,您需要做的就是

$s3->putFile("me.png", "my-own-bucket/Pictures/Me.png",
    array(Zend_Service_Amazon_S3::S3_ACL_HEADER =>
          Zend_Service_Amazon_S3::S3_ACL_PUBLIC_READ));

默认情况下,对象作为常规存储存储在存储桶中。 zend框架中是否有任何功能允许我指定对象在S3中存储为Reduced Redundancy Storage(RRS)?

如果没有,我可以将存储桶中所有对象的默认存储设置为RRS吗?

在RockyFords建议之后你有没有尝试过以下内容? 下面的代码应该以正确的模式上传。

$s3->putFile("me.png", "my-own-bucket/Pictures/Me.png",
    array(
        Zend_Service_Amazon_S3::S3_ACL_HEADER => Zend_Service_Amazon_S3::S3_ACL_PUBLIC_READ,
        'x-amz-storage-class' => 'REDUCED_REDUNDANCY'
    )
);

看起来您可以将第三个参数传递给Zend_Services_S3::putFile and putObject $meta并且它接受标量或数组。

public function putFile($path, $object, $meta=null)
    {
        $data = @file_get_contents($path);
        if ($data === false) {
            /**
             * @see Zend_Service_Amazon_S3_Exception
             */
            require_once 'Zend/Service/Amazon/S3/Exception.php';
            throw new Zend_Service_Amazon_S3_Exception("Cannot read file $path");
        }

        if (!is_array($meta)) {
            $meta = array();
        }

        if (!isset($meta[self::S3_CONTENT_TYPE_HEADER])) {
           $meta[self::S3_CONTENT_TYPE_HEADER] = self::getMimeType($path);
        }

        return $this->putObject($object, $data, $meta);
    }

和S3只想更改标题以将对象或文件设置为RRS:

  

问:如何指定我想使用RRS存储数据?

     

Amazon S3中的所有对象都具有存储类设置。默认   设置是STANDARD。您可以在PUT请求中使用可选标头   指定设置REDUCED_REDUNDANCY。

你可能需要深入研究一下API以找到准确传递的内容,但这应该指向正确的方向。

如果出现以下错误。在php.ini中简单地增加文件上传大小。默认是2 mb增加20mb或根据您的要求。
