我用这个函数代替了任何 Laravel 的东西。:/ (从网上其他地方偷来的)
public static function big_download($path, $name = null, array $headers = array()) {
if (is_null($name))
$name = basename($path);
$finfo = finfo_open(FILEINFO_MIME_TYPE);
$pathParts = pathinfo($path);
// Prepare the headers
$headers = array_merge(array(
'Content-Description' => 'File Transfer',
'Content-Type' => finfo_file($finfo, $path),
'Content-Transfer-Encoding' => 'binary',
'Expires' => 0,
'Cache-Control' => 'must-revalidate, post-check=0, pre-check=0',
'Pragma' => 'public',
'Content-Length' => File::size($path),
'Content-Disposition' => 'inline; filename="' . $name . '.' . $pathParts['extension'] . '"'
), $headers);
finfo_close($finfo);
$response = new Symfony\Component\HttpFoundation\Response('', 200, $headers);
// If there's a session we should save it now
if (Config::get('session.driver') !== '') {
Session::save();
}
// Below is from http://uk1.php.net/manual/en/function.fpassthru.php comments
session_write_close();
ob_end_clean();
$response->sendHeaders();
if ($file = fopen($path, 'rb')) {
while (!feof($file) and (connection_status() == 0)) {
print(fread($file, 1024 * 8));
flush();
}
fclose($file);
}
// Finish off, like Laravel would
Event::fire('laravel.done', array($response));
$response->foundation->finish();
exit;
}
