Symfony2登陆后跳转到访问前页面

1、修改配置文件app/config/security.yml中自己的firewall部分，添加配置：

frontend_secured_area:
    pattern:    ^[/a-z]*/member
    anonymous:  ~
    http_basic: ~
    form_login:
        provider:       frontend_authorization_database
        check_path:     expacta_member_check
        login_path:     expacta_member_login
        default_target_path:    expacta_member_dashboard
        success_handler:        expacta_member.authorization_handle
        use_forward:    false
        use_referer:    true  //需要设置为true
    remember_me:
        key:        'expacta-symfony2-frontend-secret'
        lifetime:   31536000
        path:       /
        domain:     ~
    logout:
        path:   expacta_member_logout
        target: expacta_member_login

2、在成功登陆的处理文件中添加代码：

//frontend_secured_area是你的firewall的名称
$key = '_security.frontend_secured_area.target_path'; 
if ($this->container->get('session')->has($key)) {
    $url = $this->container->get('session')->get($key);
    $this->container->get('session')->remove($key);
}else{
    $url = $this->container->get('router')->generate('member_home');
}
return new RedirectResponse($url);
