我正在使用以下代码从服务器下载mp3文件。代码在我的本地系统(Windows操作系统(中运行良好。
但是，当我将代码移动到服务器(Linux(时，我收到找不到文件错误。我确定文件路径正确且文件可读
if ($fd = fopen ($filePath, "r")) {
$fsize = filesize($filePath);
$path_parts = pathinfo($filePath);
$ext = strtolower($path_parts["extension"]);
switch ($ext) {
case "mp3":
header("Content-type: audio/mpeg"); // add here more headers for diff. extensions
header("Content-Disposition: attachment; filename='"".$originalFileName."'""); // use 'attachment' to force a download
break;
default;
header("Content-type: application/octet-stream");
header("Content-Disposition: filename='"".$originalFileName."'"");
}
header("Content-length: $fsize");
header("Cache-control: private"); //use this to open files directly
while(!feof($fd)) {
$buffer = fread($fd, 2048);
echo $buffer;
}
}
fclose ($fd)
以下是我编写该代码的方式：
// A couple of sanity checks on the file path, return a meaningful error message for debugging
if (!file_exists($filePath)) {
header('HTTP/1.1 404 Not Found');
exit('The requested file was not found');
} else if (!is_readable($filePath)) {
header('HTTP/1.1 403 Forbidden');
exit('The requested file is not accessible');
}
// Get the content type from the extension
// Consider using finfo instead: http://php.net/manual/en/ref.fileinfo.php
$contentTypes = array(
'mp3' => 'audio/mpeg',
'jpg' => 'image/jpeg',
'gif' => 'image/gif'
// etc etc
);
$ext = strtolower(pathinfo($filePath, PATHINFO_EXTENSION));
$contentType = (isset($contentTypes[$ext])) ? $contentTypes[$ext] : 'application/octet-stream';
// Content-* headers
header("Content-Length: ".filesize($filePath));
header("Content-Type: {$contentType}");
// You will always want the same Content-Disposition: header, regardless of file type
// The only time you would need a different one is if you want to serve "inline" content
header("Content-Disposition: attachment; filename='"{$originalFileName}'"");
// No-Cache headers
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); // Date in the past
// We don't want the script to time out on large files
set_time_limit(0);
// Output the file
readfile($filePath);
exit;
