@liyu001989 谢谢你，为什么我改成了User也一样报错列。
Usermodel代码：
<?php
namespace App\Models;

use Tymon\JWTAuth\Contracts\JWTSubject;
use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Auth;
use Spatie\Permission\Traits\HasRoles;

class User extends Authenticatable implements JWTSubject
{

use Notifiable;

public function getJWTIdentifier()
{

    return $this->getKey();
}

public function getJWTCustomClaims()
{

    return [];
}

}

auth.php配置：
'guards' => [
'web' => [
'driver' => 'session',
'provider' => 'users',
],

    'api' => [
        'driver' => 'jwt',
        'provider' => 'users',
    ],
],

AuthorizationsController代码：

namespace App\Http\Controllers\Api;

use App\Models\User;
use Symfony\Component\HttpFoundation\Request;
use Dingo\Api\Auth\Auth;
use App\Http\Requests\Api\AuthorizationRequest;

class AuthorizationsController extends Controller
{
public function store(AuthorizationRequest $request)
{
// $username = $request->username;

// filter_var($username, FILTER_VALIDATE_EMAIL) ?
// $credentials['email'] = $username :
// $credentials['phone'] = $username;

    $credentials['password'] = $request->password;
    $credentials['name'] = $request->name;
    if (!$token = \Auth::guard('api')->attempt($credentials)) {
        return $this->response->errorUnauthorized('用户名或密码错误');
    }

    return $this->response->array([
        'access_token' => $token,
        'token_type' => 'Bearer',
        'expires_in' => \Auth::guard('api')->factory()->getTTL() * 60
    ])->setStatusCode(201);
}

}

前面跟着教程都走通了，不知道为什么就是用户名密码登录这里就会报错。。。

@liyu001989 好了，user模型找错了。。auth.php改成这样就好了
'providers' => [
'users' => [
'driver' => 'eloquent',
'model' => App\Models\User::class,
],

我这个也报这个错,他为啥用上jwt的auth了 不是用的自带的auth么
