网站不在使用symfony 2的服务器上运行

Question

我在symfony2中有一个程序，我有一个带有Cpanel的apache服务器

该项目在本地运行良好，但当我将其上传到服务器上时，会出现以下错误：

Whoops, looks like something went wrong.
1/1 ServiceNotFoundException: The service "security.firewall.map.context.secured_area" has a dependency on a non-existent service "authentication_handler".

我不知道该怎么做？\我已经给予了正确的权限来缓存和记录目录，并编辑了本地IP的配置，但是没有错误的改变！

任何帮助都会得到认可。

Answer 1

这意味着它找不到您的身份验证服务。

阅读这篇文章，这可能会帮助您清理security.yml。

Symfony2 Login and Security

就像你提到的那样；

您需要像这样的身份验证处理程序services.yml。

services:
    authentication_handler:
        class: Acme\TestBundle\Handler\AuthenticationHandler
        calls:
             - [ setContainer, [ @service_container ] ] 

编写security.yml的正确方法是；

security:
    firewalls:
        admin_area:
            form_login:
                success_handler: authentication_handler

在将项目上传到服务器之前，先清除dev缓存并测试dev(web/app_dev.php)。

然后转移到生产，并清除它的驱动-缓存和测试。如果您对服务器进行了适当的本地测试(web/app.php)，那么您将不会在服务器中遇到这些错误。

希望这能有所帮助。干杯!

Answer 2

$ app/console container:debug | grep authentication_handler

如果结果为空，则尚未配置服务
