【中文标题】我无法在 Cakephp 4 中进行身份验证，错误 500

【英文标题】：i can't authenticated in Cakephp 4 , error 500

【发布时间】：2021-12-06 18:43:44

【问题描述】：

我正在尝试通过用户俱乐部进行身份验证，但收到错误 500 内部服务器，我不明白为什么，仅在使用身份验证时才会发生。也许是配置错误？

firefox 控制台错误 - GET http://localhost/learnwithus/users 500 内部服务器错误

我的控制器

                    'controller' => 'Users',
                    'action' => 'index',

用户表

<?php

     *
     * @param array $config The configuration for the Table.

用户

class User extends Entity

    // Make all fields mass assignable for now.
    protected $_accessible = ['*' => true];

    // ...

    protected function _setPassword($password)
    
        if (strlen($password) > 0) 
            return (new DefaultPasswordHasher)->hash($password);
        
    
    /**
     * Fields that are excluded from JSON versions of the entity.
     *
     * @var array
     */
    protected $_hidden = [
        'password',
    ];

【问题讨论】：

查看日志，在配置应用程序中将调试设置为 true，并将错误日志发布到您的问题中。

你的意思是在 boostrap CLI 中的盐水？

不行，你需要查看app/logs/error.log

我已经使用 error.log 中的堆栈跟踪编辑了我的帖子。

【参考方案1】：

显然您没有正确或以任何方式实现身份验证中间件。

以下是有关如何操作的完整说明：
