问题描述
我有一个正在构建的自卷式 MVC 框架，到目前为止已经设法避免了对任何 AJAX 调用的需要.但是，现在我想创建一个实时更新的提要.
I have a self-rolled MVC framework that I am building, and up to this point have managed to avoid the need for any AJAX calls. Now, however, I'd like to create a real-time updating feed.
我的问题是，通常在 MVC 中存储的 ajax 调用处理程序在哪里?我应该将它们存储在参与调用的同一个控制器中吗?
My question is, where are the handlers for the ajax calls usually stored in an MVC? Should I store them in the same controller that is involved in making the call?
例如，如果我的域 www.example.com/browse/blogs(browse 是控制器，blogs 是方法)正在对更新的博客列表进行 AJAX 调用，该调用是否只是对 www.example 的调用.com/browse/update_list 什么的?
For example, if my domain www.example.com/browse/blogs (browse is the controller, blogs is the method) is making an AJAX call for an updated list of blogs, would the call simply be to www.example.com/browse/update_list or something?
或者，它是一个单独的 AJAX-only 控制器吗?www.example.com/ajax/update_blogs
OR, so it be to a separate AJAX-only controller? www.example.com/ajax/update_blogs
你是怎么做到的?
推荐答案
我认为 Ajax 请求与非 Ajax 请求完全相同:实际上，从HTTP 协议.
I'd say an Ajax request is exactly the same as a non-Ajax one : it works exactly the same way, actually, from a point of view of HTTP Protocol.
唯一的区别是您返回的是一些非格式化数据，如 JSON 或 XML (嘿，这与生成 ATOM 提要 ^^ 相同)，或者只是一个HTML 页面.
The only difference is that you are returning some non-formated data, as JSON or XML (hey, this is the same as generating an ATOM feed ^^ ), or only a portion of an HTML page.
因此，我会将它们视为任何其他普通"HTTP 请求，并按照非 Ajax 请求的方式放置它们.
So, I would treat those as any other "normal" HTTP request, and place them the way I would for non-Ajax requests.
一种半替代的想法可能是在您的控制器中只有一个操作:/browse/blogs -- 并始终调用该操作.
A semi-alternate idea might be to have only one action in your controlller : /browse/blogs -- and always call that one.
但是，它会检测它是否通过 Ajax 请求，并且会:
But, it would detect if it's being via an Ajax request or not, and would :
- 如果通过正常"请求调用，则返回完整页面
- 或者如果通过 Ajax 请求调用，则只返回一些数据(或页面的一部分)
注意:这不是一个疯狂"的想法；例如，Zend Framework 提供了一些东西来促进这一点(参见 12.8.4.3. ContextSwitch 和 AjaxContext )
Note : that's not a "wild" idea ; Zend Framework, for instance, provides some stuff to facilitate that (see 12.8.4.3. ContextSwitch and AjaxContext )
