Laravel錯誤反射異常函數不存在

Question

我面臨這個錯誤，無法找到問題的地方，因爲它只提到函數（）不存在，起初我雖然蓋帽的問題，因爲函數F是在帽但是我不是那種情況，因爲如果有人能夠指出這一點，我已經瀏覽了每一行代碼很多次。

這種情況是這樣的，我有一個登錄頁面與mysql中的虛擬播種機數據。 PHP表單用於驗證用戶，然後重定向到儀表板頁面，但在重定向時顯示錯誤頁面。

屏幕截圖是否有幫助。

道歉冗長代碼。

您忘記使用/ login路徑中的用法。 這會是這樣

Route::post('/login', ['as'=>'login', 'uses'=>'LoginController@postLogin']);
