Question

我的下载脚本有问题当我下载任何文件时，它以0kb保存。有任何想法吗？这是我的PHP脚本

<?php
$file = $_GET['fname'];
$fullpath = get_bloginfo('template_url')."/application/display/1358947404.pdf";
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($fullpath));
header('Expires: 0');
header('Cache-Control: must-revalidate');
ob_clean();
flush();
readfile($fullpath);
?>

Answer 1

请同时添加内容长度标题。

请试试这个： -

<?php
$file = $_GET['fname'];

$fullpath = get_bloginfo('template_url')."/application/display/1358947404.pdf";

$headers = get_headers($fullpath, 1);// use file absolute path here
$fsize = $headers['Content-Length'];

header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($fullpath));
header('Expires: 0');
header('Cache-Control: must-revalidate');
header("Content-Length: " . $fsize);
ob_clean();
flush();
readfile($fullpath);
?>

尝试以下代码希望它能为您提供帮助。

我已经在我的localhost中测试了这个。

$file = $_GET['fname'];

$fullpath = get_bloginfo('template_url')."/application/display/1358947404.pdf";
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($fullpath));
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($fullpath));
ob_clean();
flush();
readfile($fullpath);

下载的文件保存为0kb并已损坏
