Php Symfony 4简单表单登录不工作

新的Symfony。在这件事上，我被难住了，挣扎了好几个小时。我正在遵循官方文档中的“传统登录表单”教程

此外，我还配置了从数据库中加载用户，如中所示。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/身份验证方面的条令

我已经检查了所有必要的文件，看起来与教程中的类似，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。它只是默默地失败了，每当我点击提交，在前端它看起来就像刷新，但在后端肯定有东西没有插入

我清除了所有条令缓存、作曲家缓存和bin/控制台缓存

我已经检查过多次的文件

编辑添加路由。yml

我不确定我错过了什么

谢谢大家对问题部分的评论，错误只是出现在

security.yaml

文件中

在

login\u path

和

check\u path

中，将它们与路径名称关联，而不是与实际路径关联

所以为了纠正我改变了

login_path: app_security_login
check_path: app_security_login

---

请您也添加您的

路线。yaml

？您在哪里定义了您的路线？亚马尔先生？它似乎忽略了此处的登录路径定义。这可能是因为您的登录表单提交到路径

app\u security\u login

，而您的security.yaml具有

login

as check\u path added security.yamlSo更改

login路径：app\u security\u login

和

check\u path:app\u security\u login

as@dbrumann建议

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

login_path: app_security_login
check_path: app_security_login
