Php Yii2访问控制

我是Yii2的新手，我努力实现访问控制并取得成功 但问题是在我成功登录并重定向到其他页面后 我的Identity\u属性总是空的。因此，如果我检查

Yii:：$app->user->isGuest

返回值总是真的

这是我的LoginHandler.php

<?php
namespace app\models;

use Yii;
use yii\base\Model;

/**
 * Login form
 */
class LoginHandler extends Model
{
    public $user_name;
    public $user_password;
    public $rememberMe = true;

    private $_user;


    /**
     * @inheritdoc
     */
    public function rules()
    {
        return [
           [['user_name', 'user_password'], 'required'],
            [['user_name', 'user_password'], 'string', 'max' => 100],
            ['user_password','authenticate'],
        ];
    }

    public function authenticate($attribute, $params){
//      return true;
    } 

    public function login()
    {

        if ($this->validate()) {
            return Yii::$app->user->login($this->getUser(), $this->rememberMe ? 3600 * 24 * 30 : 0);            
        } else {
            return false;
        }
    }

    protected function getUser()
    {
        if ($this->_user === null) {
            $this->_user = User::findByUsername($this->user_name);
        }
        return $this->_user;
    }
}

    namespace app\models;
    use Yii;

    /**
     * This is the model class for table "user".
     *
     * @property integer $user_id
     * @property string $user_name

     */
    class User extends \yii\db\ActiveRecord implements \yii\web\IdentityInterface{

        public $id;
        public $authKey;

        /**
         * @inheritdoc
         */
        public static function tableName()
        {
            return 'user';
        }

        /**

         */
        public function rules()
        {
            return [
                [['user_name', 'user_password'], 'required'],
                [['user_name', 'user_password'], 'string', 'max' => 100]
            ];
        }

        /**
         * @inheritdoc
         */
        public function attributeLabels()
        {
            return [
                'user_id' => 'User ID',
                'user_name' => 'User Name',
                'user_password' => 'User Password',
            ];
        }

        public static function findIdentity($id)
        {
            return static::findOne($id);
        }

        public static function findIdentityByAccessToken($token, $type = null)
        {
            return static::findOne(['access_token' => $token]);
        }

        public function getId()
        {
            return $this->id;
        }

        public function getAuthKey()
        {
            return $this->authKey;
        }

        public function validateAuthKey($authKey)
        {
            return $this->authKey === $authKey;
        }

        public static function findByUsername($username){
            return static::findOne(['user_name' => $username]);
        }
    }

    <?php
$params = array_merge(
    require(__DIR__ . '/../../common/config/params.php'),
    require(__DIR__ . '/../../common/config/params-local.php'),
    require(__DIR__ . '/params.php'),
    require(__DIR__ . '/params-local.php')
);

return [
    'id' => 'app-backend',
    'basePath' => dirname(__DIR__),
    'controllerNamespace' => 'backend\controllers',
    'bootstrap' => ['log'],
    'modules' => [],
    'components' => [
        'user' => [

            'loginUrl'  => ['login/signin'],
            'enableAutoLogin' => true,
        ],      
        'log' => [
            'traceLevel' => YII_DEBUG ? 3 : 0,
            'targets' => [
                [
                    'class' => 'yii\log\FileTarget',
                    'levels' => ['error', 'warning'],
                ],
            ],
        ],
        'errorHandler' => [
            'errorAction' => 'site/error',
        ],
    ],
    'params' => $params,
];

最后一个是我的配置main.php

<?php
namespace app\models;

use Yii;
use yii\base\Model;

    public $user_name;

    public function authenticate($attribute, $params){

看起来您应该检查

Yii::$app->user->identity

您在问题中提到了访问控制。在Yi2中，AccessControl是管理控制器内部访问规则的特殊行为类：


我在您的代码中没有看到
AccessControl

无论如何

最可能的问题是在用户类的实现中。
查看您的代码，我可以想象表结构是：
user\u id（PK）、user\u name、user\u password
。
如果是，那么方法
getId（）
将返回变量
（
$this->id
）从未初始化。但Yii使用此方法在会话中存储当前用户。在您的情况下，它应该返回
$this->user\u id

如果你想让
记住我
工作，你应该正确地实现
getAuthKey
和
validateAuthKey

详情如下:

如果这没有帮助，则显示将身份验证数据传递给
LoginController
的表结构和视图代码。当用户模型在app\models命名空间中定义时，为什么在配置中有“backend\models\User”？如果我在配置中更改为app\models，仍然无效您使用的模板是什么，您在哪里调用
Yii:：$app->user->isGuest
？似乎您的会话cookie配置不正确。显示您的common/config/main.php、common/config/main-local.php和config/main-local.php文件。两项：1）什么是
获取类方法（\Yii:：$app->user）返回？2） 为了保持一致性，建议遵循代码样式指南。（Perosnal建议是PSR的。）
