MVC 读取控制器和动作的 url [英] MVC reading the url for controller and action

问题描述

我为 php 编写了自己的 mvc，它似乎对我来说工作正常.但是我在获取控制器和操作时遇到了麻烦:

I wrote my own mvc for php, and it seems to be working fine for me. But i am having trouble with getting the controller and the action:

http://www.example.com/controller/action

这工作正常，但只要对 url 进行小的更改，我的代码就会中断.例如:

this works fine but as soon as there are small changes to the url my code breaks appart. for example:

http://www.example.com/controller?这中断了，说 controller? 不存在，

http://www.example.com/controller? thi breaks, saying the controller? doesn't exist,

http://www.example.com/controller/action?这中断了，说 action? 不存在，

http://www.example.com/controller/action? thi breaks, saying the action? doesn't exist,

我不明白为什么它需要 ? 在那里，如果有人知道更强大的方法来获得我很想知道的正确控制器和动作.

i can't figure out why it takes the ? in there and if any body know a more robust to get the correct controller and action i would love to know.

这是我的代码:

使用 .htaccess

class Framework {

   ....

   private function setup() {
     $uri = (isset($_SERVER['REQUEST_URI']))?$_SERVER['REQUEST_URI']: false;
     $query = (isset($_SERVER['QUERY_STRING']))?$_SERVER['QUERY_STRING']: '';
     $url = str_replace($query,'',$uri);
     $arr = explode('/',$url);
     array_shift($arr);
     $this->controller =!empty($arr[0])?$arr[0]:'home';
     $this->action = isset($arr[1]) && !empty($arr[1])?$arr[1]:'index';
   }
}

推荐答案

$_SERVER['QUERY_STRING'] 不包括 ? 所以当你做 $url = str_replace($query,'',$uri);，你不是在替换 ?.因此，它正在寻找名为 controller?

$_SERVER['QUERY_STRING'] does not include the ? so when you do $url = str_replace($query,'',$uri);, you are not replacing the ?. It's therefore looking for a controller named controller?

有多种方法可以解决这个问题

There are various ways around this

• 替换为 '?'.$query
• 使用 explode('?', $url) 将查询字符串与 URI 分开
• 获取$_SERVER['REQUEST_URL'](不包括查询字符串)，而不是获取整个内容然后自己拆分

• replace with '?'.$query
• Use explode('?', $url) to separate the query string from the URI
• Get the $_SERVER['REQUEST_URL'] (which doesn't include the query string), rather than getting the whole thing and then splitting out yourself

就我个人而言，我会选择最后一个选项，因为在任何已经为您编写的代码中，它往往比您可以编写的任何内容都更快、更健壮.

Personally I would go with the last option, because wherever the code is already written for you, it tends to be quicker and more robust than anything you can write.
