php - Laravel 在使用 HTTPS 时添加/删除字符

Question

我的 laravel 项目中有一些 zip 文件，它们是通过简单的方法下载的

return response()->download($path);

现在我添加了强制 https 到网站:

if (!(isset($_SERVER['HTTPS']) && ($_SERVER['HTTPS'] == 'on' ||
   $_SERVER['HTTPS'] == 1) ||
   isset($_SERVER['HTTP_X_FORWARDED_PROTO']) &&
   $_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https'))
{
   $redirect = 'https://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
   header('HTTP/1.1 301 Moved Permanently');
   header('Location: ' . $redirect);
   exit();
}

现在我无法读取 zip 文件，它们似乎已损坏。

我用十六进制编辑器打开其中一个，我看到开头多了一个 0a0a 字符。

我不知道为什么会这样，也不知道这意味着什么。尤其是如何在不编辑下载文件的情况下修复它。
