Rails catch-all route
提问by Evil Nodoer
I am using rails 3.0.14, and I am constructing routes.rb using the resourceful style. I'd like to have a wildcard route that catches all requests that do not match to any route stated.
我正在使用 rails 3.0.14，我正在使用足智多谋的风格构建 routes.rb。我想要一个通配符路由来捕获所有与任何指定路由都不匹配的请求。
What's the appropriate way to construct such a route?
构建这样一条路线的合适方法是什么？

put
放
match '*path' => 'your_controller#your_action'
at the end of the routes.rb file. This is important, since the routes are stepped through top down.
在 routes.rb 文件的末尾。这很重要，因为路由是自上而下的。

For Rail 4, you need to specify the request type:
对于 Rail 4，您需要指定请求类型：
match "*path", to: "application#custom_action", via: :all
As others have said, put this at the very bottom of your routes file.
正如其他人所说，将其放在路由文件的最底部。

It is not mandatory to use exactly "path" in the match '*path'statement. You can set a whatever token there:
在match '*path'语句中完全使用“路径”不是强制性的。您可以在那里设置任何令牌：
get "*string1"
or
或者
get "*string2"
Rails will assign your real HTTP-query to the param named after your token, example:
Rails 会将您的真实 HTTP 查询分配给以您的令牌命名的参数，例如：
get "*user" => "users#show"
in console:
在控制台中：
Started GET "/john" ....
Processing by UsersController#show as HTML
Parameters: {"user"=>"john"}
You can use more than one asterisks, say get "*id*user". But in this case you will get some unpredictable result, because Rails processes 2 or more asterisks "in an intuitive way" - for more info see http://guides.rubyonrails.org/routing.html#route-globbing-and-wildcard-segments
您可以使用多个星号，例如get "*id*user"。但在这种情况下，您会得到一些不可预测的结果，因为 Rails 以“直观的方式”处理 2 个或更多星号 - 有关更多信息，请参见http://guides.rubyonrails.org/routing.html#route-globbing-and-wildcard -段

In addition to @steel and @awenkhh, I recommend adding the following to that route's controller action
除了@steel 和@awenkhh，我建议将以下内容添加到该路由的控制器操作中
respond_to do |format|
format.html
# other formats you already support
format.all { render text: '' }
end
Otherwise, you'll wind up with some ActionView::MissingTemplate: Missing templateerrors for formats that you weren't expecting.
否则，您最终会遇到一些ActionView::MissingTemplate: Missing template意想不到的格式错误。
[rant]Particularly helpful for those people trying erroneous attack vectors around /wp-admin/css/wp-admin.cssand the like. I seem to get about 100 requests for /wp-admin/*a day, from super annoying people who apparently would like me to get a more expensive Rollbar account plan.[/rant]
[rant]对那些尝试错误的攻击向量/wp-admin/css/wp-admin.css等的人特别有帮助。我似乎/wp-admin/*每天收到大约 100 个请求，来自超级讨厌的人，他们显然希望我获得更昂贵的 Rollbar 帐户计划。[/rant]
