[注意]也请参阅最终解决方法，向下滚动

经过12个小时的轰炸和阅读大量材料后，我放弃了并要求别人帮我解决“安全上下文不包含身份验证令牌。一个可能的原因可能是没有为防火墙配置防火墙这个网址。）“问题。

如何将安全上下文正确传递给我的自定义处理程序？

我有以下设置：

Env：prod
调试：false

“未登录”错误404没有任何问题，因为没有添加任何安全性，但是为登录成员显示不同的一个让我感到痛苦，所以请提供建议。谢谢！

我不会粘贴error404_not_loggedin.html.twig和error404_loggedin.html.twig的内容，因为问题和解决方案不需要它。

Answer 1

安全逻辑在路由逻辑之后执行（在2.1之前，之前执行）。这意味着路由器抛出的404错误无法使用安全性，因为还没有关于安全性的信息。

当然，你也可以在安全信息可用的控制器中抛出404错误。要使它在任何情况下都可用，请检查安全上下文是否可用并设置，如果没有，只需渲染未登录的模板
