对于我的控制器中不需要视图的操作，我将禁用布局和模板，如下所示：

$this->autoRender = false;

这一切都很好。然而，在同一个动作中，我正在呼应“通过”或“失败”以表明我对结果的看法。问题是还回显了一堆文本：（最后是我的“失败”或“通过”）

 <!--

    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

        </body>
</html>
<!--

and open the template in the editor.
-->
<!DOCTYPE html>
<html>
    <head> ....

这被重复了 8 到 9 次。

我怎样才能摆脱这种情况，所以只有我的“通过”或“失败”才会得到回应？你能帮我吗？

我试过了

$this->layout = false; and
$this->render(false);

非常感谢。

首先，我将在http://api.cakephp.org/class/controller下粘贴来自 cakeapi 的片段，了解 autoRender 的工作原理：

autoRender boolean设置为 true 以在操作逻辑之后
自动渲染视图。

所以这：

 $this->autoRender = false ;

通常会在操作逻辑完成后关闭渲染视图。所以这就是为什么你会从你的动作逻辑中得到回声。您可以是否从代码中删除回声以防止显示它们或尝试此模式，

如果有问题：

$this->Session->setFlash('Error');
$this->redirect(array('action' => 'your_error_page'));

这会将您移动到带有错误字符串作为 Flash 文本的错误页面，或者当一切正常时：

$this->Session->setFlash('Its fine dude!');
$this->redirect(array('action' => 'your_ok_page'));
