我正在开发一个内置于 codeigniter 的项目，该项目大量使用路由和 remap 函数来重写 url。当前的实现令人困惑和混乱。
本质上，这就是设计师试图完成的事情：
www.example.com/controller/method/arg1/ 至 www.example.com/arg1/controller/method/
任何人都可以提出一个干净的方法来完成这个吗？
这实际上只需要发生在一个特定的控制器上。如果所有其他控制器只需要遵循正常的 /controller/model/arg1... 模式就可以了
只是为了让您了解当前代码在此处的外观是“路由”文件：（并没有真正研究对此代码的任何见解，只是想让您了解我正在处理的当前设置有多混乱和。我想把它扔掉，用更好的东西代替它）
// 我们需要指定管理控制器和函数，这样它们就不会被视为竞赛
$route['admin/users'] = 'admin/users';
$route['admin/users/(:any)'] = 'admin/users/$1';
$route['admin'] = 'admin/index/';
$route['admin/(:any)'] = 'admin/$1';
// same goes for sessions and any other controllers
$route['session'] = 'session/index/';
$route['session/(:any)'] = 'session/$1';
// forward http://localhost/ball/contests to controller contests method index
$route['(:any)/contests'] = 'contests/index/$1';
// forward http://localhost/ball/contests/vote (example) to controller contests method $2 (variable)
$route['(:any)/contests/(:any)'] = 'contests/index/$1/$2';
// forward http://localhost/ball/contests/users/login (example) to controller users method $2 (variable)
$route['(:any)/users/(:any)'] = 'users/index/$1/$2';
// if in doubt forward to contests to see if its a contest
// this controller will 404 any invalid requests
$route['(:any)'] = 'contests/index/$1';
$route['testing/'] = 'testing/';
以及随之而来的重映射功能：
public function _remap($method, $params = array()){
// example $params = array('ball', 'vote')
// params[0] = 'ball', params[1] = 'vote'
/*
* Write a detailed explanation for why this method is used and that it's attempting to accomplish.
* Currently there is no documentation detailing what you're trying to accomplish with the url here.
* Explain how this moves the contest name url segment infront of the controller url segment. Also
* explain how this works with the routing class.
* */
$count = count($params);
if($count == 0){ // no contest specified
redirect('http://messageamp.com');
return;
}
$contest_name = $params[0];
unset($params[0]); //remove the contest name from params array because we are feeding this to codeigniter
if($count < 2) // no method specified
$method = 'index';
else{
$method = $params[1];
unset($params[1]);
}
//We need to scrap this, lazy-loading is a best-practice we should be following
$this->init(); //load models
//make sure contest is valid or 404 it
if(!$this->central->_check_contest($contest_name)){
show_404();
return;
}
$this->data['controller'] = 'contests';
$this->data['method'] = $method;
$this->data['params'] = $params;
// call the function if exists
if(method_exists($this, $method)){
return call_user_func_array(array($this, $method), $params);
}
show_404(); // this will only be reached if method doesn't exist
}
