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*/
