Silex SecurityServiceProvider抛出“标识符""security.authentication_providers"，没有定义.' [英] Silex SecurityServiceProvider throws 'Identifier "security.authentication_providers" is not defined.'

问题描述

我不知道如何在Silex中使用SecurityServiceProvider.我的配置是:

I can't figure out how to use SecurityServiceProvider in Silex. My configuration is:

$app['security.firewalls'] = array(
    'admin' => array(
        'pattern' => '^/_admin/.+',
        'form' => array('login_path' => '/_admin/', 'check_path' => '/_admin/login_check'),
        'logout' => array('logout_path' => '/_admin/logout'),
        'users' => array(
            'admin' => array('ROLE_ADMIN', '5FZ2Z8QIkA7UTZ4BYkoC+GsR...'),
        ),
    ),
);
$app->register(new Silex\Provider\SecurityServiceProvider());

这只是抛出:

Fatal error: Uncaught exception 'InvalidArgumentException' with message 'Identifier "security.authentication_providers" is not defined.'

根据文档，在某些情况下，如果您想在处理请求之外访问安全功能，则必须致电$app->boot();，但这不是我的情况.
如果我在$app->register(...)之前调用$app->boot();，它不会引发任何异常，但可能根本无法启动，因为然后在生成登录表单时，Twig会抛出:

According to the documentation in some cases when you want to access Security features outside of the handling of a request you have to call $app->boot(); but this isn't my situation.
If I call $app->boot(); before $app->register(...) it doesn't raise any exception but it probably doesn't boot at all because then in generating login form Twig throws:

Unable to generate a URL for the named route "_admin_login_check" as such route does not exist.

几个月前有一个一个问题，可能存在相同的问题，但已关闭，因此我想应该现在就解决

There's an issue a few months ago with probably the same problem but it's closed so I guess it should be fixed now

推荐答案

在尝试在TwigServiceProvider之前注册SecurityServiceProvider时，我遇到了相同的异常.

I was getting the same exception when trying to register the SecurityServiceProvider before the TwigServiceProvider.

我刚刚更改了注册顺序(安全 之后 Twig )，一切开始正常运行:

I just changed the registering order (Security after Twig) and everything started to work fine:

// Twig service

$app->register(new Silex\Provider\TwigServiceProvider(), array(
    'twig.path' => sprintf("%s/../views", __DIR__),
));

// Security service

$app["security.firewalls"] = array();
$app->register(new Silex\Provider\SecurityServiceProvider());
