Symfony2：未找到产品 404 = 200？

Question

在 prod 环境中，当请求不存在的 URI（例如 .../green）时，我希望呈现自定义 404 错误页面。响应头是

Date: Sat, 16 Nov 2013 19:11:55 GMT
Server: Apache/2.4.4 (Win32) PHP/5.4.8
X-Powered-By: PHP/5.4.16
Content-Length: 2455
Keep-Alive: timeout=5, max=100
Connection: Keep-Alive
Content-Type: text/html

200 OK

响应是

我越是试图理解这一点，我就越感到困惑。文档说将呈现app\Resources\TwigBundle\views\Exception 中的简单error404.html.twig。 （是的，我已经清除了产品缓存 - 多次！产品日志中没有条目。）文档是否错误，我真的需要创建一个异常处理程序来显示这个 404 页面，因为响应是 200？

更新：

所以我猜开发环境中的 404 并不意味着产品中的 404。然后我尝试了一个简单的异常处理程序来获取自定义错误页面，但没有 Monolog 邮件。尝试将自定义处理程序与 Monolog 集成会导致以下结果，因为自定义处理程序使用 Twig。难怪我头晕目眩。

[Symfony\Component\DependencyInjection\Exception\ServiceCircularReferenceException] Circular reference detected for service "router", path: "cache_warmer -> router -> monolog.logger.router -> mana.exception.controller -> templating -> twig -> templating.helper.logout_url".

Answer 1

不是很明显，错误是由于错误的 error404.html.twig 文件造成的。一旦纠正它就会变得有用。道歉。
