调用示例

/**

 *日期:2020-12-21
 */

header('Content-type:text/html; Charset=utf-8');
require_once 'ALiPayNotify';
//支付宝公钥,账户中心->密钥管理->开放平台密钥,找到添加了支付功能的应用,根据你的加密类型,查看支付宝公钥
$alipayPublicKey='';

$aliPay = new ALiPayNotify($alipayPublicKey);
//验证签名
$result = $aliPay->rsaCheck($_POST,$_POST['sign_type']);
if($result===true && $_POST['trade_status'] == 'TRADE_SUCCESS'){
    //处理你的逻辑,例如获取订单号$_POST['out_trade_no'],订单金额$_POST['total_amount']等
    //程序执行完后必须打印输出“success”(不包含引号)。如果商户反馈给支付宝的字符不是success这7个字符,支付宝服务器会不断重发通知,直到超过24小时22分钟。一般情况下,25小时以内完成8次通知(通知的间隔频率一般是:4m,10m,10m,1h,2h,6h,15h);
    echo 'success';exit();
}
echo 'error';exit();
