一、根目录下controllers
// BaseController.php
?php
namespace app\controllers;
use yii\web\{Controlle, IdentityInterface, Response};
use Yii;// 继承 yii\web\controller, 其他controller则继承BaseController
class BaseController extends Controller
{/*** 错误码*/protected $code ;/*** 错误消息*/protected $msg success;/*** 响应报文*/protected $rspData [];/*** 模型*/protected $model null;/*** 路由*/protected $route;public function __construct($id, $module, $config []){$this-route Yii::$app-requestedRoute;Yii::info(json_encode($this-request(), JSON_UNESCAPED_SLASHES), [ERQUEST BODY] $this-route);parent::__construct($id, $module, $config);}/*** 设置拦截器*/public function behaviors(): array{return [];}public function init(){parent::init();}/*** 获取get参数*/protected function get($key ){$get $key ?

}?二、根目录下models
// BaseModel.php
// 继承yii\db\ActiveRecord, 增删改查操作数据库
?php
namespace app\models;use yii\db\{ActiveRecord, ActiveQuery, Connection, Exception};
use Yii;abstract class BaseModel extends ActiveRecord
{public $page 1; // 查询limit页码public $pageSize 20;protected static $insertId 0; // 插入数据的的ID/*** 调用父依赖构造函数** param array $config*/public function __construct($config []){parent::__construct($config);}/*** 数据库实例* return Connection interface*/public function dbInstance(): Connection{$db static::getDb();
