私は現在、オープン ソース フォーラム ソフトウェアの修正を開発しています。この変更により、ユーザーはそのフォーラム ソフトウェアを通じて寄付できるようになります。
ただし、最近、私のコードが原因である可能性がある問題がユーザーから報告されました。私は別のオープン ソース ライブラリを使用して IPN 接続を処理します - An IPN Listener PHP class。
この問題を報告したユーザーは、次の電子メールを受信しています:
こんにちは
<My Name>、PayPal 即時支払い通知 (IPN) を処理するサーバーを確認してください。次の URL に送信される即時支払い通知が失敗します。
http://www.MySite.com/donate/handler.phpこの URL に心当たりがない場合は、IPN を使用しているサービス プロバイダーを使用している可能性があります。上記の情報をご利用のサービス プロバイダーにお問い合わせください。この問題が続く場合は、アカウントの IPN が無効になっている可能性があります。
この問題に早急にご注意いただきありがとうございます。
ペイパル
問題が私の側にあるのではないかと心配しているので、これを調べて確認する必要があります。
IPN Listener スクリプトを少し変更したため、変更がこの問題の原因であると考えられます。Paypal にも最近、この問題を引き起こした可能性のあるいくつかの変更がありました。
これは、クラスが一時的にどのように見えるかです:

この問題を引き起こしているこのスクリプトに問題はありますか?
PS: URL donate/handler.phpは確かに IPN ハンドラ/リスナー ファイルなので、認識された URL です。
