当我注入安全。上下文在我的symfony2服务(twig扩展)出现以下错误:
在非对象上调用成员函数getUser() .....
class GeninnoShareboardExtension extends 'Twig_Extension {
public function __construct(ContainerInterface $container, SecurityContext $context) {
$this->doctrine = $container->get('doctrine');
$this->context = $context;
}
public function getUser() {
return $this->context->getToken()->getUser();
}
........
}
我的服务。Yml看起来像这样:
services:
geninno.twig.extension.dashboard:
class: Geninno'EDSBundle'Twig'Extension'GeninnoShareboardExtension
arguments:
container: "@service_container"
service: "@security.context"
tags:
- { name: twig.extension }
一个用户登录了，我的防火墙设置如下:
access_control:
- { path: ^/secured/register, roles: IS_AUTHENTICATED_ANONYMOUSLY }
- { path: ^/secured/create, roles: IS_AUTHENTICATED_ANONYMOUSLY }
- { path: ^/secured/login, roles: IS_AUTHENTICATED_ANONYMOUSLY }
- { path: ^/, roles: [IS_AUTHENTICATED_FULLY, IS_AUTHENTICATED_REMEMBERED] }
你应该试试
services:
geninno.twig.extension.dashboard:
class: Geninno'EDSBundle'Twig'Extension'GeninnoShareboardExtension
arguments: [@service_container, @security.context]
tags:
- { name: twig.extension }
是在防火墙后面你得到错误的页面?否则它将无法访问安全令牌。您需要将页面置于防火墙之后，然后将其开放给未经身份验证的用户。
类似这样的内容应该可以将页面打开给未经身份验证的用户，但仍然将其置于防火墙内(security.yml)
access_control:
- { path: /lost_password, roles: IS_AUTHENTICATED_ANONYMOUSLY}
我通过在SecurityContext调用中添加if来解决这个问题。检查GetToken()返回的是对象(authenticated)还是字符串(anonymous)
if (is_object($this->context->getToken()))
{
.... // getUser() etc.
}
