Question

我已登录主域名。说 example.com （在传统kohana中开发的应用程序）。我正在尝试登录到子域名，例如 foo.bar.example.com 。

foo.example.com是symfony app。以下是我的配置。 Dev too bar显示“匿名”用户。它不会从cookie中的会话ID中注册用户。

我是否需要配置至少一个身份验证提供程序？要么我需要编写自定义身份验证提供程序，就像记住我一样吗？

的Symfony \元器件\安全\ HTTP \防火墙\ AbstractAuthenticationListener-＆GT;处理

有

  if ($this->options['require_previous_session'] && !$request->hasPreviousSession()) {
                throw new SessionUnavailableException('Your session has timed out, or you have disabled cookies.');
            }

和请求

public function hasPreviousSession()
{
    // the check for $this->session avoids malicious users trying to fake a session cookie with proper name
    return $this->hasSession() && $this->cookies->has($this->session->getName());
}

Answer 1

在主域中，登录后，您可以将令牌保存到数据库和cookie中，在第二个应用程序中，您应该创建一个自定义身份验证器，该身份验证器可以从导航器中恢复令牌并提取到数据库中。如果找到匹配项，它将对用户进行身份验证。

希望它能解决您的问题

如果已登录到其他应用程序中的主域，如何使用symfony安全性登录子域？
