实际上，我正在用 php 创建一个类似于 Java Servlet 模型的框架，但使用 Facebook Big pipeline 类似技术。
为了清楚地看一下这个Servlet(PHP Servlet)
<?php
class login_servlet extends Servlet{
public function doGet($request, $response){
$response->getWriter()->write('hii');
} // __ end of doGet
public function doPost($request, $response){ } // end of doPost
} // __ Servlet
?>
所以当用户输入http://myweb.com/login时
这个servlet将被调用，映射将由框架完成，框架会做这样的事情:-
$servlet_name = genrate_servlet_name('login');
$servlet_boj = new $servlet_name(new Request(), new Response());
$servlet_obj-> init(new ServletConfig());
$servlet_obj-> service();
$servlet_obj-> destroy();
所以我们可以说单个 servlet 类似于 MVC 中的 Controller ，并且根据 doGet 或 doPost 方法将由框架调用，正如我上面使用请求和响应参数所解释的那样，但是 View 分为多个 pagelet，例如:-
正如您在图片中看到的，此页面包含 4 个小页面:-
1 个 header 2 中间偏左部分 3 中右部分(登录部分) 4页脚
所以login_servlet代码看起来像这样:-
<?php
class login_servlet extends Servlet{
public function doGet($request, $response){
$writer = $response->getWriter();
$pg_strucutre = new PageletIndexStructure($request, $response);
$writer->writePagelet($pg_strucutre);
$pg = new PageletIndexHead($request, $response);
$writer->writePagelet($pg);
$pg = new PageletIndexLeft($request, $response);
$writer->writePagelet($pg);
$pg = new PageletIndexRight($request, $response);
$writer->writePagelet($pg);
$pg = new PageletIndexFooter($request, $response);
$writer->writePagelet($pg);
} // __ end of doGet
public function doPost($request, $response){ } // end of doPost
} // __ Servlet
?>
pagelet 类看起来是这样的，每个 pagelet 都必须扩展:-
<?php
class Pagelet{
public $template_name = '';
public $js = array();
public $css = array();
public $output = null;
public $container_id = 'root'; // __default is root
private $request = null;
private $response = null;
function __construct($request, $response){
$this->request = $request;
$this->response = $response;
$this->doProcess();
/* default */
} // __ construct
public function doProcess(){
// __ here all code will comes
} // __doprocess
public function render(){
$arr = array(
'js' => $this->js,
'css' => $this->css,
'content' => $this->output,
'container_id' => $this->container_id,
'response_type' => 2
);
return json_encode($arr);
} // __ end of render
} // __ end of class
?>
客户端响应如下所示:-

所以我的问题是我做得对还是我需要改变一些东西,,？抱歉英语不好:(，提前谢谢
最佳答案
很难回答“我这样做对吗？”这样的问题。您有什么需要具体反馈的吗？尝试问一个非常有针对性的问题。
关于 Bigpipe 的博文:https://www.facebook.com/notes/facebook-engineering/bigpipe-pipelining-web-pages-for-high-performance/389414033919
由于它不是开源的，我认为您不会找到很多有关内部结构的信息。这里有一个开放的实现:http://www.juhonkoti.net/2010/10/01/open-bigpipe-javascript-implementation 。也许这可以进一步帮助您。
关于javascript - Facebook Bigpipe，做得对还是不对？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/29385303/
