我使用Wordpress插件Donate Plus，它在一段時間內還沒有更新，而且對於大多數用戶來說它不能正常工作。所以我對代碼做了一些修改，試圖讓它再次運行。除了在我的PayPal賬戶的IPN歷史記錄中，所有交易都具有「重試」狀態並具有404的HTTP響應代碼，我的一切工作都很好。PayPal IPN傳送狀態設置爲「重試」HTTP響應代碼404
腳本中有一個IPN調試功能，它返回「已驗證IPN交易[已完成]「，表明一切都已經完成。但是，我收到了多條調試消息，發送了多條感謝消息以及多條條目到我的MySQL數據庫中，所有這些我都認爲與「重試」問題有關。
我已經在PayPal中手動設置了通知URL，因爲我聽說這可以解決一些問題。不過，我仍然遇到同樣的問題。
我瞭解腳本需要將完整的未更改的IPN消息發送回PayPal;即消息必須以相同的順序包含相同的字段，並且以與原始消息相同的方式編碼。但是我不確定如何檢查$ postipn返回的內容，以便檢查這是否是問題。
我包括在任何人的情況下充分paypal.php下面的腳本能發現什麼問題是：

感謝您的回答。根據你上面提到的代碼，我已經評論了這一點，並將兩個標題設置爲「Status：200 OK」，但仍然出現404錯誤。此外，腳本不會死亡，並且我正在收到以「已驗證」狀態發送的IPN調試電子郵件，所以我非常確定這不是問題。就其他可能性而言，我確信IPN URL是正確的（點2）。我將檢查另外兩個問題並儘快回覆您。 – Nick 2012-08-10 12:01:19
就重定向問題而言（第3點），我之前將通知URL設置爲'http：// www。[URL ...]'，我仍然收到404錯誤。這是否意味着問題與重定向無關？ – Nick 2012-08-10 12:58:49
關於第1點，處理提交PayPal付款的腳本僅將IPN URL設置在一個地方，這是正確的URL。 – Nick 2012-08-10 13:02:07
