Laravel 7-如何在登录时更改数据库？

php artisan make:controller CustomLoginController

use Illuminate\Support\Facades\Auth;
use Illuminate\Http\Request;

public function login(Request $request)
{
    $credentials = $request->only('email', 'password');

    if (Auth::attempt($credentials)) {
        // 登录成功，可以在这里更改数据库

        return redirect()->intended('/dashboard');
    }

    return back()->withErrors([
        'email' => '登录失败，请检查您的凭据。',
    ]);
}

Route::post('/login', 'CustomLoginController@login')->name('login');
