PHP頭200 OK不會發送

Question

我想從控制器內發送HTTP/1.0 200 OK內的CakePHP

，但每次我這樣做，瀏覽器接收HTTP 404，而不是未找到。

繼https://bugs.php.net/bug.php?id=27026，我要送

HTTP/1.0 299 OK 

任何想法，我缺少的是什麼？

Apache的版本2.2.21

PHP版本5.3.8

CakePHP的2.0

Answer 1

我需要爲此創建健康狀態報告以實現AWS負載平衡。

將傳入支票指向正確加載的網頁對我來說有什麼竅門。

我將狀態檢查器指向www.yourdomain.com並返回了正確的信號。

嘗試在調試設置爲2的瀏覽器中加載頁面。如果cake返回錯誤，則不會發送正確的信號。爲您的控制器創建一個視圖文件，以避免錯誤發生，並且您可能會開始生成正確的信號。

Answer 2

CakePHP路由器存在一個問題，我希望它能夠正常工作。它不喜歡url中的％char，並且如果它在URL中看到％，就會拋出404條件。

Answer 3

我遇到了同樣的問題，幾乎通過我的顯示器扔了一杯。您可能需要爲標題調用使用替代語法：

header('Status: 200'); 

這似乎是PHP與服務器交互方式的問題。
