我正在使用 Zend Framework 2 开发网站,其中客户端希望能够将某些数据导出到Excel文件。为此,我选择了 PHPExcel ,然后我在本地计算机上运行它,我在那里运行Apache2。
<?php
//Create a writer for Excel
$objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);
// Get the data from php://output
// https://stackoverflow.com/questions/16551375/phpexcel-in-zend2-controller
ob_flush();
ob_start();
$objWriter->save('php://output');
$excelOutput = ob_get_clean();
//Get a new response object
$response = new \Zend\Http\Response();
//Set headers for the response object
$response->getHeaders()
->addHeaderLine('Last-Modified: ' . gmdate("D, d M Y H:i:s") . ' GMT')
->addHeaderLine('Cache-Control: no-store, no-cache, must-revalidate')
->addHeaderLine('Cache-Control: post-check=0, pre-check=0')
->addHeaderLine('Pragma: no-cache')
->addHeaderLine('Content-Type', 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet')
->addHeaderLine('Content-Disposition: attachment;filename="report.xlsx"');
//Set the content for the response object
$response->setContent($excelOutput);
return $response;
?>
问题在于,当我将项目上传到生产服务器时,使用 PHP-FPM 以非常标准的设置运行 Nginx , Excel文件未使用正确的标头发送。看起来他们被#34; text / html&#34;这使浏览器显示一些乱码,而不是让文件可供下载。
我按照这个(PHPExcel in Zend2 Controller)问题将内容转换为变量。
我无法弄清楚为什么会发生这种情况,使用 Apache 上的 PHP 而不是使用 Nginx 设置标头的方式不同 PHP-FPM
