网站建站卡顿怎么办,做网站用什么代码编写,做网站哪个编辑器好用,网站建设服务费属于buildAdmin的代码生成#xff0c;很像是 fastadmin 的生成模式#xff0c;当我们利用数据库生成了一个控制器的时候#xff0c;我们可以看到#xff0c; 它的生成代码很简洁 ?phpnamespace app\admin\controller\askanswer;use app\common\controller\Backend;/*** 回…buildAdmin的代码生成很像是 fastadmin 的生成模式当我们利用数据库生成了一个控制器的时候我们可以看到 它的生成代码很简洁 ?phpnamespace app\admin\controller\askanswer;use app\common\controller\Backend;/*** 回答管理*/
class Answer extends Backend //控制器继承了 backend
{/*** Answer模型对象* var object* phpstan-var \app\admin\model\Answer*///定义了一个 模型对象也就是对应数据表的 模型protected object $model;//这里是在添加数据中 排除了一些自动生成的字段 在Backend中有对这些字段的调用protected array|string $preExcludeFields [id, create_time, update_time];//这里是设置了前端的快速搜索protected string|array $quickSearchField [id];public function initialize(): void{parent::initialize(); //这里用了父类的 初始化方法 做了一些 用户认证权限判断数据库连接检测等$this-model new \app\admin\model\Answer;$this-request-filter(clean_xss); //这里对 request 做了一次 xss 攻击的过滤}/*** 若需重写查看、编辑、删除等方法请复制 see \app\admin\library\traits\Backend 中对应的方法至此进行重写*/
}接着我们来到父类 backend 在追代码的过程中我没有看到 跨域的操作 因为fastadmin 在这里面是有跨域操作的一段代码的后来经过 整块代码搜索 才想起来 这是tp8了 是有中间键的而fastadmin中是tp5.0,没有中间键的 真正的 增删改查的代码 就在traits中
?phpnamespace app\admin\library\traits;use Throwable;
use think\facade\Config;/*** 后台控制器trait类* 已导入到 see \app\common\controller\Backend 中* 若需修改此类方法请复制方法至对应控制器后进行重写*/
