我尝试从数据库登录。据我所知，我只需要替换默认模型用户。所以我尝试了两次，但在这两种情况下 Yii::$app->user->isGuest 都是 true 但必须是 false
LoginForm.php
<?php
namespace app\models;
use Yii;
use yii\base\Model;
class LoginForm extends Model
{
public $username;
public $password;
public $rememberMe = true;
private $_user = false;
/**
* @return array the validation rules.
*/
public function rules()
{
return [
// username and password are both required
[['username', 'password'], 'required'],
// rememberMe must be a boolean value
['rememberMe', 'boolean'],
// password is validated by validatePassword()
['password', 'validatePassword'],
];
}
public function validatePassword($attribute, $params)
{
if (!$this->hasErrors()) {
$user = $this->getUser();
if (!$user || !$user->validatePassword($this->password)) {
$this->addError($attribute, 'Incorrect username or password.');
}
}
}
public function login()
{
if ($this->validate()) {
return Yii::$app->user->login($this->getUser(), $this->rememberMe ? 3600*24*30 : 0);
} else {
return false;
}
}
public function getUser()
{
if ($this->_user === false) {
$this->_user = User::findByUsername($this->username); //default
# $this->_user = Users::findByUsername($this->username);//my try 1
# $this->_user = Users2::findByUsername($this->username); // my trey 2
}
return $this->_user;
}
}
Users.php
<?php
namespace app\models;
use Yii;

最佳答案
在你的配置更改中
'user' => [
'identityClass' => 'app\models\User',
'enableAutoLogin' => true,
到
'user' => [
'identityClass' => 'app\models\Users',//or Users2
'enableAutoLogin' => true,
