  • Request請(qǐng)求對(duì)象和Response響應(yīng)對(duì)象

  • $_GET、$_POST、$_REQUEST、$_COOKIE

  • 調(diào)用請(qǐng)求對(duì)象$request=Request::instance()

  • $this->request或request()->url();助手函數(shù)

  • input()助手函數(shù)

  • 響應(yīng)格式 json xml 模板渲染

  • 頁(yè)面跳轉(zhuǎn) 重定向

  • $this->success $this->error $this->redirect
