Question

我正在尝试从CakePHP内的控制器发送HTTP / 1.0 200 OK

但每次我这样做时，浏览器都会收到HTTP 404 Not Found。

关注https://bugs.php.net/bug.php?id=27026，我必须发送

HTTP/1.0 299 OK

知道我错过了什么吗？

Apache 2.2.21版

PHP版本5.3.8

CakePHP 2.0

我遇到了同样的问题，几乎在我的显示器上扔了一个杯子。您可能需要使用标题调用的替代语法：

header('Status: 200');

PHP与服务器交互的方式似乎存在问题。

Answer 2

我需要这样做才能为AWS负载平衡创建健康状况报告。

将传入的支票定向到正确加载的网页是我的诀窍。

我将状态检查程序指示到www.yourdomain.com并返回了正确的信号。

尝试在浏览器中加载页面，调试设置为2.如果蛋糕返回错误，则不会发送正确的信号。为您的控制器创建一个视图文件，以便不会恢复任何错误，您可能会开始生成正确的信号。
