我已经使用 PHP 集成了 Razorpay 付款，但在捕获付款时出现错误，并出现以下错误。
Notice: Undefined index: razorpay_signature in /Applications/XAMPP/xamppfiles/htdocs/feedback/dashboard/admin/verify.php on line 27
Warning: hash_equals(): Expected user_string to be a string, null given in /Applications/XAMPP/xamppfiles/htdocs/feedback/dashboard/admin/razorpay-php/src/Utility.php on line 32
截屏：
未定义索引：Razorpay 签名
注意：在我的情况下，支付产生的金额是动态的！
