PHPExcel不下载xls

Question

看到了许多类似的问题，但无济于事。 我使用PHPExcel。 我试过了

$filename = "report.xls";
header("Content-Type: application/vnd.ms-excel; charset=utf-8");
header("Content-Disposition: attachment; filename=".$filename);
header("Cache-Control: max-age=0");
header("Content-Type: application/octet-stream");
header("Content-Description: File Transfer");
header("Content-Transfer-Encoding: Binary");
$objWriter = PHPExcel_IOFactory::createWriter($pExcel, 'Excel5');
$objWriter->save("php://output");

和这个

$filename = "report.xlsx";
    header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
    header("Content-Disposition: attachment; filename=\"".$filename."\"");
    header("Cache-Control: max-age=0");
    header("Content-Type: application/octet-stream");
    header("Content-Description: File Transfer");
    header("Content-Transfer-Encoding: Binary");
    $objWriter = PHPExcel_IOFactory::createWriter($pExcel, 'Excel2007');
    $objWriter->save("php://output");

但是它会在浏览器中显示为“ PKoCjKG.D.X。[Content_Types].xml MN.0....”“，并且不会强制下载。

Answer 1

如果之前确定过，请将文件名更改为$ filename。 例：

require_once 'Classes/PHPExcel.php';
$objPHPExcel = new PHPExcel();
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename='.$filename);
header('Cache-Control: max-age=0');
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save('php://output');

Answer 2

对我来说有用。

header("Content-Type: application/vnd.ms-excel; charset=UTF-8");
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");
header("Content-Disposition: attachment; filename=output.xls");

Answer 3

尝试更换

header("Content-Type: application/vnd.ms-excel; charset=utf-8");

用

header('Content-type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');

我遇到了类似（不确切）的问题，并通过上述代码修复了它，我也在这里使用了它。
