在Symfony 3 Controller中获取请求和会话

我有一个大问题,请帮助我。所以我想创建一个只使用以下用户的登录系统:

List<WebElement> elements = dr.findElements(By.xpath("//div[@id='menu']"));

所以我的全球路由:providers: in_memory: memory: users:

/app/config/routing.yml

我在AdminBundle中的路由:

app_admin:
    resource: "@AppAdminBundle/Resources/config/routing.yml"
    prefix:   /admin

我的LoginController:

app_admin_homepage:
    path:     /
    defaults: { _controller: AppAdminBundle:Login:index }
login:
    path:   /login
    defaults:  { _controller: AppAdminBundle:Login:login }
login_check:
    path:   /login_check

我的login.html.twig:

<?php

namespace App\AdminBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\Security\Core\SecurityContext;

class LoginController extends Controller
{
public function indexAction()
{
    return $this->render('AppAdminBundle:Member:login.html.twig');
}
public function loginAction()
{
    $request = $this->get('request');
    $session = $this->get('session');

    if ($request->attributes->has(SecurityContext::AUTHENTICATION_ERROR)) {
        $error = $request->attributes->get(SecurityContext::AUTHENTICATION_ERROR);
    } else {
        $error = $session->get(SecurityContext::AUTHENTICATION_ERROR);
        $session->remove(SecurityContext::AUTHENTICATION_ERROR);
    }

    return $this->render('AppAdminBundle:Member:login.html.twig', array(
        'last_username' => $session->get(SecurityContext::LAST_USERNAME),
        'error'         => $error,
    ));
}
}

我的security.yml:

<form class="login-form" action="{{ path('login_check') }}">
    <div class="login-wrap">
        <p class="login-img"><i class="icon_lock_alt"></i></p>
        <div class="input-group">
            <span class="input-group-addon"><i class="icon_profile"></i></span>
            <input type="text" id="username" name="_username" value="{{ last_username }}" class="form-control" placeholder="Username" autofocus>
        </div>
        <div class="input-group">
            <span class="input-group-addon"><i class="icon_key_alt"></i></span>
            <input type="password" class="form-control" id="password" name="_password" placeholder="Password">
        </div>
        <button class="btn btn-primary btn-lg btn-block" type="submit">Login</button>
    </div>
</form>

当我尝试访问时:security: role_hierarchy: ROLE_ADMIN: ROLE_USER ROLE_FMTI: ROLE_FMTI ROLE_SUPER_ADMIN: [ROLE_USER, ROLE_ADMIN, ROLE_ALLOWED_TO_SWITCH] access_control: - { path: ^/login, role: IS_AUTHENTICATED_ANONYMOUSLY } - { path: ^/admin, role: IS_AUTHENTICATED_ANONYMOUSLY } firewalls: dev: pattern: ^/(_(profiler|wdt)|css|images|js)/ security: false secured_area: pattern: ^/admin anonymous: ~ form_login: login_path: /admin/login check_path: /admin/login_check access_control: - { path: ^/admin, roles: ROLE_ADMIN } providers: in_memory: memory: users: admin: { password: 111111, roles: 'ROLE_FMTI' } encoders: Symfony\Component\Security\Core\User\User: plaintext

我收到此错误:/admin/login

你能帮帮我吗?提前致谢并抱歉我的英文

而不是这个

$this->get('request')

使用

$this->get('request_stack')->getCurrentRequest()

答案 1 :(得分:8)

这是因为您试图在控制器中获得不存在的服务。在symfony控制器中,您可以在方法调用中获取请求:

在您的Logincontroller中,添加以下用语:

use Symfony\Component\HttpFoundation\Request;

在你的函数声明中

public function loginAction(Request $request)
{
    // you can directly use $request
    ....
}

您现在可以删除尝试获取不存在服务的行:

// remove this line
$request = $this->get('request');

此外,我不确定您是否会使用get(&#39; session&#39;)进行会话。基于Symfony&#39;文档,您应该执行以下操作:

$session = $request->getSession();

正是@jiboulex所说的,补充它:

由于内部使用D:\home\site\wwwroot\home\pkp_analyse\https:\web.config 的{​​{1}}已弃用。 如果您检查迁移指南,则明确进行此更改: https://github.com/symfony/symfony/blob/master/UPGRADE-3.0.md#frameworkbundle

关于会话,您可以通过文档中的$this->getRequest()获取该会话: http://symfony.com/doc/current/book/controller.html#managing-the-session
