Laravel：参数 2 传递给 Illuminate\Auth\SessionGuard::__construct()

Question

我有一个应用程序，我在其中创建了一个名为 residents 的新守卫，它是 laravel 附带的默认 User class 的精确副本。但是当我改变守卫时，它开始显示这个错误：
Argument 2 passed to Illuminate\Auth\SessionGuard::__construct() must be an instance of Illuminate\Contracts\Auth\UserProvider, null given, called in ...\vendor\laravel\framework\src\Illuminate\Auth\AuthManager.php on line 125

我尝试用谷歌搜索解决方案并阅读了很多但没有任何效果。

Laravel版本是5.8

auth.php

    'guard' => 'web',
    'passwords' => 'users',

Answer 1

您的 config/auth.php 出现问题。您的 web 守卫正在使用未在您的 providers 数组中声明的 users 提供程序。您有 2 个选项来解决此问题（选择一个）：

添加 users 提供商
如果您不打算使用 web 守卫，请将其移除，然后将您的默认守卫设置为 api:

'defaults' => [
    'guard' => 'api',
    'passwords' => 'residents',
],

'guards' => [
    'api' => [
        'driver' => 'token',
        'provider' => 'residents',
        'hash' => false,
    ],
],

'providers' => [
    'residents' => [
        'driver' => 'eloquent',
        'model' => App\ApiModels\Resident::class,
    ],
],

'passwords' => [
    'residents' => [
        'provider' => 'residents',
        'table' => 'password_resets',
        'expire' => 60,
    ],
],

Answer 2

您必须将此用于网络防护：

'users' => [
            'driver' => 'eloquent',
            'model' => App\Models\User::class,
        ],

或

您可以删除网络防护：
