使用nginx和PHPExcel设置内容类型

我正在使用Zend Framework 2开发一个站点，客户希望能够将一些数据导出到Excel文件中。为此，我使用了PHPExcel，并在本地计算机上运行它，在那里我运行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;
?>

Nginx头文件：

您可以从Apache env和nginx one中转储头文件吗？我现在从这两个环境中添加了头文件。请参阅pastie，我无法复制您的案例：。提供的代码返回提供的标题。我想这不是代码的这一部分，而是一个nginx设置，或者基于您的环境php版本、fw版本等的一些差异。我尝试了您的pastie代码，也得到了正确的标题。这让我走上了另一条道路，我设法解决了这个问题。这是第一次初步的ob_冲洗，这是这个问题的根源。我无法理解为什么这会影响nginx而不是apache。谢谢你花时间帮我解决这个问题
