php - TypeError: Illuminate\Auth\SessionGuard::login(): 参数 #1 ($user) 必须是类型 Illuminate\Contracts\Auth\Authenticatable,, App\Models\Admin giv

Question

我是 laravel 的初学者。我正在使用 guard 进行多重授权。我在我的管理员登录中遇到了这个问题: 类型错误 Illuminate\Auth\SessionGuard::login():参数 #1 ($user) 必须是 Illuminate\Contracts\Auth\Authenticatable 类型，App\Models\Admin 给定，在 C:\Users\DELL\survey 中调用\app\Http\Controllers\AdminController.php 第 34 行

这是 AdminController.php 文件

<?php

namespace App\Http\Controllers;
use App\Models\Admin;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\Hash;
use Illuminate\Contracts\Auth\Authenticatable;

class AdminController extends Controller
{
    public function login()
    {
        return view('admin.login');
    }
    public function authenticate(Request $request)
    {
        $request->validate([
            'email' => ['required', 'email'],
            'password' => ['required']
        ]);

        /** @var Admin $model */
        $model = Admin::query()->where('email', $request->get('email'))->firstOrFail();

        if(!$model){
            return back()->with('error', 'Email or password is incorrect');
        }

        if (!Hash::check($request->get('password'), $model->password)) {
            return back()->with('error', 'Email or password is incorrect');
        }

        Auth::guard('admin')->login($model);

        return redirect()->route('dashboard')
            ->with('success', 'Welcome ' . $model->name . '!');
    }
}

这是 login.blade.php

<x-guest-layout>
    <x-auth-card>
        <x-slot name="logo">
            <a href="/">
                <x-application-logo class="w-20 h-20 fill-current text-gray-500" />

            @csrf

                <x-input id="password" class="block mt-1 w-full"
                                type="password"
                                name="password"
                                required autocomplete="current-password" />
            </div>

            <!-- Remember Me -->
            <div class="block mt-4">
                <label for="remember_me" class="inline-flex items-center">

                </label>
            </div>

            <div class="flex items-center justify-end mt-4">
                @if (Route::has('password.request'))
                    <a class="underline text-sm text-gray-600 hover:text-gray-900" href="{{ route('password.request') }}">
                        {{ __('Forgot your password?') }}
                    </a>
                @endif

                <x-button class="ml-3">
                    {{ __('Log in') }}
                </x-button>
            </div>
        </form>
    </x-auth-card>
</x-guest-layout>

我该如何解决这个问题？

Answer 1

您的 Admin 模型应该扩展为可验证的!

use Illuminate\Foundation\Auth\User as Authenticatable;   
class Admin extends Authenticatable
{
   //Your code
}
