Question

这看起来很基本，但我无法理解它。

我正在尝试向控制器中的方法发送多个参数，如下所示：

http://localhost/ci/index.php/subjects/3/state

这是我尝试过的路线：

$route['subjects/(:num)'] = 'subjects/view/$1';
$route['subjects/(:num)/{:any}'] = 'subjects/view/$1/$2';

方法接受了2个参数：

public function view($slug, $id = null){

}

但我似乎得到了404.我怎么能让它工作？我需要view方法总是接受1个参数和可选的其他参数。

注意：我包含了网址助手。

Answer 1

您的路线支架有问题，只需将其从{}更改为（）括号将起作用

这

$route['subjects/(:num)/{:any}'] = 'subjects/view/$1/$2';

到

$route['subjects/(:num)/(:any)'] = 'subjects/view/$1/$2';

Answer 2

始终维护您的路由规则

像

$route['subjects/(:num)/(:any)/(:any)/(:any)'] = 'subjects/view/$1/$2/$3/$4';
$route['subjects/(:num)/(:any)/(:any)'] = 'subjects/view/$1/$2/$3';
$route['subjects/(:num)/(:any)'] = 'subjects/view/$1/$2';

始终遵循此模式进行路由

如果你这样添加

$route['subjects/(:num)/(:any)'] = 'subjects/view/$1/$2';
$route['subjects/(:num)/(:any)/(:any)/(:any)'] = 'subjects/view/$1/$2/$3/$4';
$route['subjects/(:num)/(:any)/(:any)'] = 'subjects/view/$1/$2/$3';

然后每次第一个条件都是真的。

Answer 3

我曾尝试过这种URI模式

$route['(:any)'] = 'welcome/list1/$1';
$route['(:any)/(:num)'] = 'welcome/list1/$1/$2';

$route['(:any)/(:any)'] = 'welcome/list2/$1/$2';
$route['(:any)/(:any)/(:num)'] = 'welcome/list2/$1/$2/$3';

$route['(:any)/(:any)/(:any)'] = 'welcome/list3/$1/$2/$3';

但它没有用......所以我用正则表达式替换它

([a-z 0-9 -]+)已取代(:any) 和 ([0-9]+)已取代(:num)

所以它变成了

$route['([a-z 0-9 -]+)'] = 'welcome/list1/$1';
$route['([a-z 0-9 -]+)/([0-9]+)'] = 'welcome/list1/$1/$2';

$route['([a-z 0-9 -]+)/([a-z 0-9 -]+)'] = 'welcome/list2/$1/$2';
$route['([a-z 0-9 -]+)/([a-z 0-9 -]+)/([0-9]+)'] = 'welcome/list2/$1/$2/$3';

$route['([a-z 0-9 -]+)/([a-z 0-9 -]+)/([a-z 0-9 -]+)'] = 'welcome/list3/$1/$2/$3';

它对我有用:)

如何将2个参数路由到控制器？
