Symfony 2:如何检查用户是否未在模板中登录? [英] Symfony 2: How do I check if a user is not logged in inside a template?

问题描述

在 Symfony 2 模板(使用 Twig)中，如何有效地检查用户是否未登录?

In Symfony 2 templates (using Twig), how can I effectively check whether a user is not logged in?

我不想使用 ROLE 检查.我想要一种简单的方法来检查用户是否未登录.

I don't want to use ROLE checks. I want a straightforward way to check if a user is not logged in.

我知道将 app.user.username 与 anon 进行比较是有效的，但这对我来说并不合适.

I'm aware that comparing app.user.username with anon works, but that just doesn't feel right to me.

推荐答案

可以查看是否设置了 app.user.

You can check if app.user is set.

 {% if app.user %}
    # user is logged in
 {% else %}
    # user is not logged in
 {% endif %}
