嗯,你的代码对我有用:
测试.php:
set_time_limit(0);
$urlParts = explode("/", $_SERVER['PHP_SELF']);
//$file = $urlParts[3];
$file = 'toread.txt';
header("Cache-Control: public, must-revalidate");
header("Pragma: hack");
header("Content-Type: application/force-download");
header('Content-Disposition: attachment; filename=' . $file);
header("Content-Transfer-Encoding: binary\n");
readfile($file);
echo md5(rand() . time());
?>
toread.txt:
这是 toread.txt 的内容
现在使用 curl,我得到以下结果:
>curl -i http://example.com/test.php
