Question

我已经在pc设备中下载了以下代码

    $file_url_source = "C:/test.xlsx";
    $file_url = "C:/test.xlsx";
    header('Content-Type: text/json; charset=UTF-8;');  
    header('Content-Description: File Transfer');
    header('Content-Type: application/octet-stream');
    header('Content-Disposition: attachment; filename="' . basename($file_url_source)."") . '"';
    header('Content-Transfer-Encoding: binary');
    header('Expires: 0');
    header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
    header('Pragma: public');
    header('Content-Length: ' . filesize($file_url));
    ob_clean();
    flush();
    readfile($file_url);

但它不适用于移动设备（我只是在Android手机上测试它并下载download.php文件）。如何让移动设备下载文件？

Answer 1

这就是你所需要的：

$file_url = "xxxxxx";
header('Content-Type: application/force-download');
header('Content-Disposition: attachment; filename="' . basename($file_url) .'"');
readfile($file_url);

你的问题在于这一行

header('Content-Disposition: attachment; filename="' . basename($file_url_source)."") . '"';
#                                                                                  ^^^^^^^^^
#              this is where your problem is, you never put the last " around the file name
