Form API 返回的 sign 值不匹配
PHP 的判断语句如下:
<code>md5($_GET['code'].'&'.$_GET['message'].'&'.$_GET['url'].'&'.$_GET['time'].'&'.UPYUN_FORMAPI_SECRET) == $_GET['sign'] </code>
DEBUG 之后两个 MD5 不一致,而且已经确认发到服务器的 sign 是正确的,各 $_GET 都有值。我是上传到图片类空间,带了 ext-param 的,是 return-url 方式的,所以 URL 里面带了 image-height 之类的和 ext-param,不知道有没有影响。

官方回复:
Hi,ext-param 是会参与到签名中去的,image-* 是不会参与加密签名的。
可以参考下:通知规则
同样的问题,不知道怎么解决的?
