in order to make it easy to change the same download link in multiple places, I made a jump with php:
public function getUavManagerLinkAction()
{
$path = "http://files-10008291.cos.myqcloud.com/app/UAVManagerProfessional.exe";
Header("Location: $path");
exit;
}
the front-end html link points to this action:
<a download="getUavManagerLink" href="/File/getUavManagerLink" target="_blank"></a>
most browsers download normally
only roaming 5 and some IE downloads result in no file suffix exe.
