Yii :: $ app-> user-> isGuest在Yii2登錄後總是會有錯誤

Question

我是Yii的新手，剛開始創建註冊和登錄模塊。 註冊工作正常，但是當我嘗試登錄Yii :: $ app-> user-> isGuest時總是如此，但是在LoginForm :: login（）中它正常工作，並且Yii :: $ app-> user包含當前用戶的信息。 LoginForm.php：含有這些設置

<?php 

namespace app\models; 

use Yii; 
use yii\base\Model; 

/** 
* LoginForm is the model behind the login form. 
* 
* @property User|null $user This property is read-only. 
* 
*/ 
class LoginForm extends Model 
{ 
    public $login; 
    public $pass; 
    public $rememberMe = true; 

    private $_user = false; 


    /** 
    * @return array the validation rules. 
    */ 
    public function rules() 
    { 
     return [ 
      // login and password are both required 
      [['login', 'pass'], 'required'], 
      // rememberMe must be a boolean value 
      ['rememberMe', 'boolean'], 
      // password is validated by validatePassword() 
      ['pass', 'validatePassword'], 
     ]; 
    } 

    /** 
    * Validates the password. 
    * This method serves as the inline validation for password. 
    * 
    * @param string $attribute the attribute currently being validated 
    * @param array $params the additional name-value pairs given in the rule 
    */ 
    public function validatePassword($attribute, $params) 
    { 
     if (!$this->hasErrors()) { 
      $user = $this->getUser(); 

      if (!$user || !$user->validatePassword($this->pass)) { 
       $this->addError($attribute, 'Wrong login or password.'); 
      } 
     } 
    } 

    /** 
    * Logs in a user using the provided login and password. 
    * @return bool whether the user is logged in successfully 
    */ 
    public function login() 
    { 
     if ($this->validate()) 
     { 
      $user = $this->getUser(); 
      if (!$user->active) 
      { 
       $this->addError('login', 'You account is not active.'); 
       return false; 
      } 
      return Yii::$app->user->login($user, $this->rememberMe ? 3600*24*30 : 0); 
     } 
     return false; 
    } 

    /** 
    * Finds user by [[login]] 
    * 
    * @return User|null 
    */ 
    public function getUser() 
    { 
     if ($this->_user === false) 
     { 
      $this->_user = User::findByLogin($this->login); 
     } 

     return $this->_user; 
    } 
}

會議是沒有數據了。但服務器會話正常工作。 查看模板有Yii :: $ app-> user-> isGuest始終爲真。 有誰知道什麼是錯的``

如果有人感興趣，我創建MySQL用戶表和字段的不同結構「狀態」被設置爲0.因此，我將其更改爲10，問題解決了...
