为什么我的 openfile.php 在 Safari 或 IE 中无法正常工作？
我有一个非常简单的文件，名为 openfile.php，它设置内容处置并强制浏览器下载指定的文件。
它在 FF 中工作正常，但在 Safari 中，它会下载一个奇怪的 .xhtml 文件，经过仔细检查，该文件似乎是会出现的默认错误页面。
在 IE 中，您只会被定向到此错误页面。
谁能推断出这里发生了什么？

这是打开文件的代码
<?php
if ( ! isset($_GET['file']) )
die();
if ( strpos( $_GET['file'], (isset($_SERVER['HTTPS']) ? 'https|' : 'http|') . $_SERVER['SERVER_NAME'] ) === false )
die();
require_once('../lib/class.mimetype.php');
$mime = new mimetype();
$fPath = str_replace('http|', 'http://', $_GET['file']);
$fPath = str_replace('https|', 'https://', $fPath);
$fType = $mime->getType( $fPath );
$fName = basename($fPath);
$origname = preg_replace('/_#_#\d*/','',$fName);
$fContent = fetch_content( $fPath );
output_content( $fContent, $origname );
function fetch_content( $url ) {
$ch = curl_init();
curl_setopt( $ch, CURLOPT_URL, $url );
curl_setopt( $ch, CURLOPT_HEADER, 0 );
ob_start();
curl_exec( $ch );
curl_close( $ch );
$fContent = ob_get_contents();
ob_end_clean();
return $fContent;
}
function output_content( $content, $name ) {
header( "Expires: Wed, 9 Nov 1983 05:00:00 GMT" );
header( "Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT" );
header( "Content-Disposition: attachment; filename=" . $name );
header( "Content-type: application/octet-stream" );
header( "Content-Transfer-Encoding: binary" );
echo $content;
}
?>
I have a very simple file called openfile.php that sets a content-disposition and forces a browser to download a specified file.
It works fine in FF, but in Safari, it downloads a strange .xhtml file that on closer examination, appears to be the default error page that would occur.
In IE, you are just directed to this error page.
Can anyone deduce what is going on here?

This is the code that opens the file
<?php
if ( ! isset($_GET['file']) )
die();
if ( strpos( $_GET['file'], (isset($_SERVER['HTTPS']) ? 'https|' : 'http|') . $_SERVER['SERVER_NAME'] ) === false )
die();
require_once('../lib/class.mimetype.php');
$mime = new mimetype();
$fPath = str_replace('http|', 'http://', $_GET['file']);
$fPath = str_replace('https|', 'https://', $fPath);
$fType = $mime->getType( $fPath );
$fName = basename($fPath);
$origname = preg_replace('/_#_#\d*/','',$fName);
$fContent = fetch_content( $fPath );
output_content( $fContent, $origname );
function fetch_content( $url ) {
$ch = curl_init();
curl_setopt( $ch, CURLOPT_URL, $url );
curl_setopt( $ch, CURLOPT_HEADER, 0 );
ob_start();
curl_exec( $ch );
curl_close( $ch );
$fContent = ob_get_contents();
ob_end_clean();
return $fContent;
}
function output_content( $content, $name ) {
header( "Expires: Wed, 9 Nov 1983 05:00:00 GMT" );
header( "Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT" );
header( "Content-Disposition: attachment; filename=" . $name );
header( "Content-type: application/octet-stream" );
header( "Content-Transfer-Encoding: binary" );
echo $content;
}
?>

你的标题是

不确定这是否是问题，因为我不使用Windows。
Your header is

Not sure if this is the problem, as I don't use windows.
即使在 Firefox 中，该链接也对我不起作用，下载的内容是一些 HTML 页面。
查看您发送的标头 (http://redbot.org/?uri=http%3A%2F%2Fhqinternetsolutions.com%2FWebsites%2FFabric%2520Traditions%2Fwp-content%2Fplugins%2Fwp-publication-archi ve%2Fincludes%2Fopenfile.php%3Ffile%3Dhttp|hqinternetsolutions.com%2FWebsites%2FFabric%2520Traditions%2Fwp-content%2Fuploads%2F2011%2F12%2FPillow1.pdf)我注意到：
（但这些都不能解释为什么发送错误的内容）
The link doesn't work for me even in Firefox, the content that get's downloaded is some HTML page.
Looking at the headers you are sending (http://redbot.org/?uri=http%3A%2F%2Fhqinternetsolutions.com%2FWebsites%2FFabric%2520Traditions%2Fwp-content%2Fplugins%2Fwp-publication-archive%2Fincludes%2Fopenfile.php%3Ffile%3Dhttp|hqinternetsolutions.com%2FWebsites%2FFabric%2520Traditions%2Fwp-content%2Fuploads%2F2011%2F12%2FPillow1.pdf) I note:
(but none of these explain why the wrong content is sent)
该 PHP 无法运行的原因是 URL 中的
%20。不能有空格，否则会导致脚本中的分隔符查找器失败。The reason this PHP will not work is because of the
%20in the URL. You can't have spaces or it causes the delimiter finder in the script to fail.
