Symfony问题：如何获取/读取页面的HTML内容？

So, I have a actions.class.php and have the function like that:

public function executeGetHTML($request)
{
   $pageName = $request->getParameter('name', '');
}

I do not want to output the content of getHTMLSuccess.php

instead, depending on the request, I need to get the HTML code of another page (without processing it ..e.g. filtering it..etc). Actually, the page content will be output in JSONP within a JSON variable. e.g.

For example, I call /getHTML?name=abc

and abc.html (or abc.php) has the content:

<div>Hello, my beautiful world</div>

then I will get the page content of Hello, my beautiful world

and output it as: mycallback({content:'Hello, my beautiful world'});

I know I can do file_get_content(...) but it sounds like very heavy to do file read explicitly while symfony should already cache and know .

include / require won't work in this... so, is there a light-weight way to do it?

You could try the getPresentationFor method (http://www.symfony-project.org/api/1_4/sfController#method_getpresentationfor)

public function executeGetHTML($request) {
  $pageName = $request->getParameter('name', '');

  $html = $this->getPresentationFor('module', 'action');
}

This will return the output for the requested module/action rather than outputing it to screen

Didnt work for me in symfony 1.4.14, until I used getController():

$html = $this->getController()->getPresentationFor('module', 'action');

And also to pass parameters to the action:

$this->getRequest()->setParameter('parameter_name', value);

Another way to pass parameters:

$html = $this->getController()->getPresentationFor('module', 'action?id=123');
