The PHP judgment statement is as follows:
md5($_GET['code'].'&'.$_GET['message'].'&'.$_GET['url'].'&'.$_GET['time'].'&'.UPYUN_FORMAPI_SECRET) == $_GET['sign']
After DEBUG two MD5 is inconsistent, and has confirmed that the sign sent to the server is correct, each $_get has a value. I was uploaded to the picture class space, with the Ext-param, is the Return-url way, so the URL with image-height and Ext-param, do not know if there is no impact.
