我正在使用 Laravel 8 制作一個網路應用程式，但我的身份驗證有點奇怪。
- 我使用
php artisan ui:auth命令創建了身份驗證。 - 注冊作業正常：將新用戶添加到資料庫，登錄用戶，重定向到主頁。
問題是，當我現在嘗試登錄到同一用戶時，表單只會重繪 并且不會讓用戶登錄。
任何幫助深表感謝。如果您需要更多資訊，請告訴我！

筆記：
- 在 PHPStorm 中，
Auth下劃線為“未定義的類身份驗證” /adminregister這是我現在注冊管理員帳戶的方式。

Auth::routes();

我嘗試過的事情
- 在網上搜索，發現一個看起來很有希望的執行緒，但解決方案是針對與我使用的身份驗證版本不同的版本：Laravel 5.2 login does not work, no redirect and no errors。
- 添加到達 后重定向回 home 的路由
/login，但這不會讓用戶登錄。 - 洗掉遷移并使用
php artisan migrate:fresh. - 其他一些事情現在讓我心煩意亂，但都無濟于事。
uj5u.com熱心網友回復：
默認情況下，laravel 使用電子郵件進行身份驗證，但如果您想使用用戶名（或其他名稱）登錄。您需要將 username() 方法覆寫到 LoginController 類中。您不需要更改 AuthenticatesUsers 中的內容，因為在我看來，這樣做不是一件好事。
/**
* Get the login username to be used by the controller.
*
* @return string
*/
public function username()
{
return 'username';
}
同樣，您也可以覆寫其他方法，但是，如果您使用電子郵件進行身份驗證，則不需要這樣做。
uj5u.com熱心網友回復：
我觀察到您正在使用username登錄 而不是email默認情況下。也許您可以嘗試更改以下內容AuthenticatesUsers？
從
public function username()
{
return 'email';
}
到
public function username()
{
return 'username';
}
