您可以尝试在LoginController.php中修改sendFailedLoginResponse函数

You can try to modify the sendFailedLoginResponse function in your LoginController.php

路径:app \ Http \ Controllers \ LoginController

Path: app\Http\Controllers\LoginController

记住要导入Illuminate \ Http \ Request和App \ User(这里是App \ Models \ User，因为我将User模型移到了App \ Models)；

Remember to import Illuminate\Http\Request and App\User(Here is App\Models\User because I moved my User model to App\Models);

<?php

namespace App\Http\Controllers\Auth;

use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use Illuminate\Http\Request;
use App\Models\User;


class LoginController extends Controller
{
    /*
    |--------------------------------------------------------------------------
    | Login Controller
    |--------------------------------------------------------------------------
    |
    | This controller handles authenticating users for the application and
    | redirecting them to your home screen. The controller uses a trait
    | to conveniently provide its functionality to your applications.
    |
    */

    use AuthenticatesUsers;

    /**
     * Where to redirect users after login.
     *
     * @var string
     */
    protected $redirectTo = '/home';

    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('guest')->except('logout');
    }

    protected function credentials(Request $request) {
      return array_merge($request->only($this->username(), 'password'), ['active' => 1]);
    }

    /**
     * Get the failed login response instance.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\RedirectResponse
     */
    protected function sendFailedLoginResponse(Request $request)
    {
        $errors = [$this->username() => trans('auth.failed')];

        // Load user from database
        $user = User::where($this->username(), $request->{$this->username()})->first();

        // Check if user was successfully loaded, that the password matches
        // and active is not 1. If so, override the default error message.
        if ($user && \Hash::check($request->password, $user->password) && $user->active != 1) {
            $errors = [$this->username() => trans('auth.notactivated')];
        }

        if ($request->expectsJson()) {
            return response()->json($errors, 422);
        }
        return redirect()->back()
            ->withInput($request->only($this->username(), 'remember'))
            ->withErrors($errors);
    }
}

顺便说一句，我在resources \ lang \ en \ auth.php中添加了一行，以便可以将trans('auth.notactivated')用作错误消息.

By the way, I add a line in resources\lang\en\auth.php so I can use trans('auth.notactivated') as my error message.

<?php

return [
    'failed' => 'These credentials do not match our records.',
    'throttle' => 'Too many login attempts. Please try again in :seconds seconds.',
    'notactivated' => 'This account has not been activated yet.',
];
