Can'；t存储用户标识Yii2

当我的用户登录并顺利通过验证时，我在

LoginForm.php

中有一个

login

函数，该函数必须在会话中保存用户。我的函数如下所示：

public function login()
    {
        if ($this->validate()) {
            $email = $this->email;
            $user = $this::find()->where(['email' => $email])->asArray()->one();
            $user['password'] = '_';
            Yii::$app->getUser()->login($user);
        }
        return false;
    }

在

SiteController

的内部，我有以下功能：

public function actionLogin()
    {
        if (!Yii::$app->user->isGuest) {
            return $this->goHome();
        }
        $model = new LoginForm();
        if ($model->load(Yii::$app->request->post()) && $model->validate() && $model->login()) {
            $this->redirect(['users/profile']);
        }

        return $this->render('login', [
            'model' => $model
        ]);
    }

问题出在我的

login

函数中，因为当我在if语句中注释

&&&$model->login（）

部分时，错误消失了

下面是我得到的错误：

Argument 1 passed to yii\web\User::login() must be an instance of yii\web\IdentityInterface, array given, called in C:\xampp\htdocs\yii_grig\models\LoginForm.php on line 72

错误是我的

login

function-

Yii:：$app->getUser（）->login（$user）中的这一行

这就是我的
models/User.php
文件的外观：

<?

namespace app\models;

class User extends \yii\db\ActiveRecord implements  \yii\web\IdentityInterface
{
    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;
    }
}

应该是这样的：

use common\models\User;

...

/**
     * Logs in a user using the provided username and password.
     *
     * @return bool whether the user is logged in successfully
     */
    public function login()
    {
        if ($this->validate()) {

            $user = $this->getUser();
            if($user){
                if($user->status === User::STATUS_ACTIVE){
                    return Yii::$app->user->login($user, $this->rememberMe ? 3600 * 24 * 30 : 0); //set session
                 }
                 //any other logic
            }
            return false;

        } else {
            return false;
        }
    }

    /**
     * Finds user by [[username]]
     *
     * @return User|null
     */
    protected function getUser()
    {
        if ($this->_user === null) {
            $this->_user = User::findByEmail($this->username);
        }

        return $this->_user;
    }

希望能有所帮助。
这就是我们应该做的：

use common\models\User;

...

/**
     * Logs in a user using the provided username and password.
     *
     * @return bool whether the user is logged in successfully
     */
    public function login()
    {
        if ($this->validate()) {

            $user = $this->getUser();
            if($user){
                if($user->status === User::STATUS_ACTIVE){
                    return Yii::$app->user->login($user, $this->rememberMe ? 3600 * 24 * 30 : 0); //set session
                 }
                 //any other logic
            }
            return false;

        } else {
            return false;
        }
    }

    /**
     * Finds user by [[username]]
     *
     * @return User|null
     */
    protected function getUser()
    {
        if ($this->_user === null) {
            $this->_user = User::findByEmail($this->username);
        }

        return $this->_user;
    }

希望能有所帮助。

您只需删除登录方法中的
->asArray（）
调用即可。同时删除这一行
$user['password']='
在删除
->asArray（）
并注释
$user['password']='足够公平。。你能发布
LoginForm:：find（）
方法吗？我在
LoginForm
中没有
find
方法，你正在调用
$this:：find（）
这里：
$user=$this:：find（）->where（['email'=>$email]）->asArray（）->one（）
这可能需要是
user:：find（）->where（['email'=>$email]）->one（）
