URL的路由參數的正則表達式

[英]regular expression for route parameter of URL

我對正則表達式不太滿意,這就是為什么我需要你的幫助。 看這里http://kohanaframework.org/3.3/guide/kohana/routing#examples

Route::set('search', ':<query>', array('query' => '.*'))
  ->defaults(array(
    'controller' => 'Search',
    'action' => 'index',
  ));

這個正則表達式( .* )除了我需要的所有參數:
cat1/cat2/cat3
但是也:
cat1/cat 2/ cat3 ”,
cat1/cat 2/ /// a |<>"?\\':*
如何修改此表達式以禁止:
1.任何空間(“ \\s ”)
2.多一個斜線(' cat1/cat2 '但不是' cat1/////cat2 ')
3.和范圍的每個符號:[ "|", "<", ">" , "\\"", "?", "\\", "'", ":", "*" ]

感謝所有試圖幫助我的人

define('CATEGORIES_RGXP', '(?:[^|<>\\?"\':*\s]+\/?)+');
Route::set('debug_route', '(<categories>/)<file>.<ext>',array(
    'categories'    => CATEGORIES_RGXP,
))
    ->defaults(array(
        'controller'        =>  'index',
        'action'            =>  'file',
    ));

當我按照“/cat1/cat2/////cat3/file.php”轉儲控制器時: var_dump($this->request->param());

array(3) {
  ["categories"]=>
  string(14) "cat1/cat2/cat3"
  ["file"]=>
  string(4) "file"
  ["ext"]=>
  string(3) "php"
}

所以它允許傳遞一組斜線

這個. 匹配解釋觀察到的行為的每個字符(新行除外)

相反,我們將使用否定的字符類,即[^X] ,這意味着“匹配除了 X之外的所有內容”

根據您的要求,您應該使用:

^((?:[^|<>\\\/?"':*\s]+\/?)+)$
