我不太擅长正则表达式,这就是为什么我需要你的帮助。http://kohanaframework.org/3.3/guide/kohana/routing#examples 看这里:
Route::set('search', ':<query>', array('query' => '.*'))
->defaults(array(
'controller' => 'Search',
'action' => 'index',
));
这个正则表达式(.*
)不包括我需要的所有参数:
"cat1/cat2/cat3
"
而且:
"cat1/cat 2/ cat3
",
"cat1/cat 2/ /// a |<>"?'':*
"
如何修改此表达式以禁止:
1. 任何类型的空格 ("'s
")
2. 多个斜杠一起( ' cat1/cat2
' 但不是 ' cat1/////cat2
')
3.和范围的每个符号:["|", "<", ">" , "'"", "?", "'", "'", ":", "*"
]
感谢所有试图帮助我的人
define('CATEGORIES_RGXP', '(?:[^|<>''?"'':*'s]+'/?)+');
Route::set('debug_route', '(<categories>/)<file>.<ext>',array(
'categories' => CATEGORIES_RGXP,
))
->defaults(array(
'controller' => 'index',
'action' => 'file',
));
当我遵循"/cat1/cat2//////cat3/file.php"时转储控制器:var_dump($this->request->param());
array(3) {
["categories"]=>
string(14) "cat1/cat2/cat3"
["file"]=>
string(4) "file"
["ext"]=>
string(3) "php"
}
所以它允许传递一组几个斜杠
.
匹配每个字符(换行符除外),这解释了观察到的行为
相反,我们将使用否定字符类,即 [^X]
这意味着"匹配除 X 之外的所有内容"
根据您的要求,您应该使用:
^((?:[^|<>'''/?"':*'s]+'/?)+)$
