我想在SwiftMailer消息中附加Excel文件。將excel流附加到swiftmailer消息?
訣竅是我不想保存excel文件,然後附加它然後刪除它,而我只是想生成excel並將其附加到消息。
這個功能可以附加OutputByteStream
/**
* Create a new Attachment.
*
* @param string|Swift_OutputByteStream $data
* @param string $filename
* @param string $contentType
*
* @return Swift_Mime_Attachment
*/
public static function newInstance($data = null, $filename = null, $contentType = null)
{
return new self($data, $filename, $contentType);
}
有一個在Symfony的PHPExcel功能捆綁創建響應
/**
* Stream the file as Response.
*
* @param \PHPExcel_Writer_IWriter $writer
* @param int $status
* @param array $headers
*
* @return StreamedResponse
*/
public function createStreamedResponse(\PHPExcel_Writer_IWriter $writer, $status = 200, $headers = array())
{
return new StreamedResponse(
function() use ($writer) {
$writer->save('php://output');
},
$status,
$headers
);
}
他們似乎調用該回調的時候都渲染效應初探,但我怎樣才能將php://輸出保存在一個變量中或將其傳遞給newInstance方法?我嘗試了$ response-> getContent()並將$ writer-> save('php:// output')傳遞給newInstance方法(我試過傳遞響應對象(StreamedResponse) 。
這將是有用的? http://stackoverflow.com/questions/4279577/php-add-attachments-to-emails-on-the-fly – BentCoder
我保存了php://輸出ob_start()和ob_get_clean() –
