登录注意

模型登录必须实现接口(implements) IdentityInterface

• 同时使用里面的方法

public static function findIdentity($id)
   {
       return self::findOne($id);
       // TODO: Implement findIdentity() method.
   }
public function getId()
   {
       return $this->id;
       // TODO: Implement getId() method.
   }
public function getAuthKey()
   {
      return $this->auth_key;
     // TODO: Implement getAuthKey() method.
}
public function validateAuthKey($authKey)
  {
     return $this->auth_key==$authKey;
    // TODO: Implement validateAuthKey() method.
}
