问题描述

我有以下问题,我将 symfony 放在服务器上,我在 app_dev.php 调试中将其更改为 false,在 app.php 中更改为 true,现在我应该在信息 php bin/console 中获取有关我有一个设置版本的信息prod,为什么 dev 总是给我看?当然,调试栏不会出现,并且在 url app_dev.php/_profiler 下我得到一个错误

Error: Can not redeclare class Symfony\Component\Debug\ErrorHandler

但是,输入 example.com/_profiler 后,我收到错误:

No route found for "GET /_profiler"

关于结果的 php bin/console,当我将 dev 更改为 false 时,prod 更改为 true

解决方案


如果你想在生产服务器或类似的东西上调试代码,我想说至少有一条黄金法则:不要修改 app_dev.php 或 app.php。您可以像往常一样保留您的 prod 环境,同时,您可以使用相应的环境(即“dev”,您已经拥有“prod”)和端口来运行 webserver 包。如您所知,代码中的任何更改都是在 dev 中即时编译的,而在 prod 中您必须清除缓存(甚至给予适当的网络服务器权限)。据我了解,您不希望有任何与此不同的内容,因此我建议恢复对 app*.php 脚本的更改并相应地运行网络服务器包。
