php - Symfony 4 简单的 form_login 不起作用

Question

Symfony 新手。我对此感到困惑并挣扎了几个小时。我正在关注this官方文档中的“传统登录表单”教程。

此外，我还配置了从数据库加载用户，如 here 中所示。 。我已经从另一个应用程序导入了数据库表，但我只需要安全/身份验证内容的 Doctrine 。

我已经检查了所有必要的文件，似乎与教程中的文件类似，但我的登录表单仍然不起作用。它不会抛出错误或任何东西。它只是默默地失败，每当我点击提交时，在前端它看起来就像刷新但在后端肯定有东西没有插入。

我清除了所有的 Doctrine 缓存、 Composer 缓存和 bin/控制台缓存。

我已经检查过多次的文件。

用户表架构

id,username,password,is_active,email

编辑添加路由.yml

app_lucky_number:
   path: /lucky/number
   controller: App\Controller\LuckyController::index

app_security_login:
   path: /login
   controller: App\Controller\SecurityController::index
app_home:
   path: /
   controller: App\Controller\IBController::home

我不确定我错过了什么。

Answer 1

感谢大家对问题部分发表评论，错误只是在 security.yaml 文件中。

在 login_path 和 check_path 处，将它们与路径名称而不是实际路径相关联。

所以为了纠正我改变了

login_path: app_security_login
check_path: app_security_login
