为什么参数中带点的路由匹配失败? [英] Why do routes with a dot in a parameter fail to match?

问题描述

我为我的用户提供了一条路线，例如 /iGEL/contributions，效果很好.但是现在一个用户注册了一个像'A.and.B.'这样的名字，现在路由不匹配，因为名字包含点.

I've got an route for my users like /iGEL/contributions, which works fine. But now a user registered with a name like 'A.and.B.', and now the route fails to match, since the name contains dots.

我的路线:

get "/:user/contributions" => 'users#contributions'

有什么想法吗?

推荐答案

查看蓝色信息框 这里:

默认情况下动态段不接受点——这是因为点用作格式化的分隔符路线.如果您需要使用点在动态段中添加一个覆盖此的约束 - 对于示例 <代码>:id =>/[^/]+/ 允许除了斜线以外的任何东西.

By default dynamic segments don’t accept dots – this is because the dot is used as a separator for formatted routes. If you need to use a dot within a dynamic segment add a constraint which overrides this – for example :id => /[^/]+/ allows anything except a slash.

例如:

get "/:user/contributions" => 'users#contributions', :constraints => { :user => /[^/]+/ }
