  [            'id' => '100',            'username' => 'admin',            'password' => 'admin',            'authKey' => 'test100key',            'accessToken' => '100-token',        ],    ];    /**     * @inheritdoc     */    public static function findIdentity($id)    {        return isset(self::$users[$id]) ? new static(self::$users[$id]) : null;    }    /**     * @inheritdoc     */    public static function findIdentityByAccessToken($token, $type = null)    {        foreach (self::$users as $user) {            if ($user['accessToken'] === $token) {                return new static($user);            }        }        return null;    }    /**     * Finds user by username     *     * @param  string      $username     * @return static|null     */    public static function findByUsername($username)    {        foreach (self::$users as $user) {            if (strcasecmp($user['username'], $username) === 0) {                return new static($user);            }        }        return null;    }    /**     * @inheritdoc     */    public function getId()    {        return $this->id;    }    /**     * @inheritdoc     */    public function getAuthKey()    {        return $this->authKey;    }    /**     * @inheritdoc     */    public function validateAuthKey($authKey)    {        return $this->authKey === $authKey;    }    /**     * Validates password     *     * @param  string  $password password to validate     * @return boolean if password provided is valid for current user     */    public function validatePassword($password)    {        return $this->password === $password;    }}

Change the code as follows:

 get('db_admin');    }    /**     * Finds user by username     *     * @param  string      $username     * @return static|null     */    public static function findByUsername($username)    {$user = User::find()->where(['username'=>$username])->asArray()->one();if(isset($user)){            $user['authKey'] = self::$AUTH_KEY;            $user['accessToken'] = self::$ACCESS_TOKEN;}return isset($user) ? new static($user) : null;    }    /**     * Validates password     *     * @param  string  $password password to validate     * @return boolean if password provided is valid for current user     */    public function validatePassword($password)    {        return $this->password === $password;    }    /**     * @inheritdoc     */    public function getId()    {        return $this->id;    }    /**     * @inheritdoc     */    public function getAuthKey()    {        return $this->authKey;    }    /**     * @inheritdoc     */    public static function findIdentity($id)    {$user = User::find()->where(['id'=>$id])->asArray()->one();if(isset($user)){            $user['authKey'] = self::$AUTH_KEY;            $user['accessToken'] = self::$ACCESS_TOKEN;}return isset($user) ? new static($user) : null;    }    /**     * @inheritdoc     */    public static function findIdentityByAccessToken($token, $type = null)    {return null;    }    /**     * @inheritdoc     */    public function validateAuthKey($authKey)    {        return $this->authKey === $authKey;    }}
