Question

我是初学者，我开始用laravel学习和编写代码...... 要启用用户登录nad注册，我写这个（正如我在一个tutorilal上看到的那样）：

在routes.php

 Route::controllers([
     'auth'=>'Auth\AuthController',
     'password'=>'Auth\PasswordController', ]);

现在当我输入：http://localhost:8888/auth/login时出现错误：

AuthManager.php第71行中的InvalidArgumentException： Auth guard []是没有定义。

同样在view文件夹中，没有auth目录和login.blade.php文件等。

Answer 1

如果您已从5.1.x升级到5.2，请确保更新config / auth.php。

https://github.com/laravel/laravel/blob/v5.2.0/config/auth.php

Answer 2

如果您修改了config/auth.php，例如要添加另一个警卫并且您的配置已缓存，您的警卫可能无法重新加载。如果您遇到此问题，清除配置将修复它。

$php artisan config:clear或$php artisan config:cache

我正在使用laravel 5.5

Answer 3

这可能是您的config / auth.php文件中的问题，其中＆＃39;默认＆＃39; array正在Laravel 5.2上设置一个不存在的防护。

Answer 4

程序目录App / config / Auth.php

<?php
 return [
/*

| Of course, a great default configuration has been defined for you
| here which uses session storage and the Eloquent user provider.

Answer 5

此问题的主要原因是您的系统无法检测到新创建的守卫。就跑

php artisan config:clear
php artisan config:cache

如果您无法在共享主机中运行以上 artisan 命令或项目，请将以下代码写入您的 web.php 文件

Route::get('/clear', function() {

    Artisan::call('cache:clear');
    Artisan::call('config:clear');
    Artisan::call('config:cache');
    Artisan::call('view:clear');
    Artisan::call('route:clear');

    return "Cleared!";

});

现在，在您的基本网址后面写上“清除”并按回车键。希望您的问题能解决。
