Ruby on Rails-错误路线的正则表达式

Question

How do I define a routes match any things exclude string ( like 'websocket' )?

Thanks!

Answer 1

Based on the comments, it sounds like you want to match /websocket to a specific action and everything else to an 404 error page.

Utilizing the fact that routes are matched in the order they are defined in routes.rb , this is a good approach to do it:

match '/websocket' => 'controller#action'
match '/:slug' => "errors#show", :code => 404, :via => [:get]

When a request /string comes, the routing subsystem will first try to match it to the first line, and if string is equal to websocket then the match is successful and no more routes will be matched.

If string is not websocket on the other hand, then it will match the second line.
