我正在我的项目中实现 ipnlistner 。我在我的 paypal 帐户中设置了 iPN url。但我没有收到对该 url 的所有交易 ipn 响应。但是当我检查帐户中的 IPN 历史记录时，它显示所有 IPN 均已发送。例如昨天它显示所有 112 个 iPN 已发送。但我的数据库中只有 7 个。这是我的 ipn listner 代码。我仅在第一行插入我在数据库中获取的所有数据。

我正在此网址上验证 IPN
https://ipnpb.paypal.com/cgi-bin/webscr https://ipnpb.paypal.com/cgi-bin/webscr
我的 IPN 网址是
https://www.myproject.com/api/verify-ipn https://www.myproject.com/api/verify-ipn
Note:之前我在此帐户上创建了一些 paypal 按钮，但我没有收到该按钮付款的 IPN 响应
请帮助或指导为此做什么..
