浏览器中的PHPS预览表下载xlsx。

Question

我想在浏览器上下载我的生成Xlsx文件，但当我执行这段代码时，请求没有错误地启动，但什么也没有发生。

   header("Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
    header('Content-Disposition: attachment; filename='.basename($pathfile).'');
    header('Cache-Control: max-age=0');


    File::setUseUploadTempDirectory(true);

    $objWriter = IOFactory::createWriter($objWorkBookExcel, 'Xlsx');

    $objWriter->save("php://output");

当我使用这个.NET技术时，我的文件是在我的服务器上生成的。

$objWriter->save($pathfile);

我的文件是在我的服务器上生成的

Answer 1

我建议使用 PHPspreedsheet PHPOffice的进化

试试吧。

$objWriter = io_factory::createWriter($objPHPExcel, 'Xlsx');


header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");;
header("Content-Disposition: attachment;filename=nameoffile.xlsx");
header("Content-Transfer-Encoding: binary ");

ob_end_clean();
ob_start();
$objWriter->save('php://output');
exit;

如果你使用PHPExcel:

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="' . $filename . '.xlsx"');
$objWriter->save('php://output');
die();

Answer 2

现在我在这里

  $objWriter = IOFactory::createWriter($objWorkBookExcel, 'Xlsx');

    header("Pragma: public");
    header("Expires: 0");
    header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
    header("Content-Type: application/force-download");
    header("Content-Type: application/octet-stream");
    header("Content-Type: application/download");;
    header("Content-Disposition: attachment;filename='nameoffile.xlsx'");
    header("Content-Transfer-Encoding: binary ");

    ob_end_clean();
    ob_start();
    File::setUseUploadTempDirectory(true);
    $objWriter->save('php://output');      
    exit;
