Question

我想在一个动作块中捕获2个类似的路线。在Rails5中，我可以轻松地做到这一点。我首先声明：

get ':folder/:file' => 'get#index', :file => /.*/, :folder => /.*/
get ':file' => 'get#index', :file => /.*/

这使得我可以捕获:folder，就像文件夹可以像a/b/c/d...和:file一样，最后一个文件名。第二个也允许我只捕获文件名。 这两条路线都针对同一行动。

但是，在Grape中，因为它被声明为块而不是路由到方法定义，所以我必须写两次相同的块...

有没有办法在一个路由参数中同时捕获/as/many/folder/and/file.ext和/file.ext？我尝试了可选参数，要求。他们都没有工作。

我使用:folder/:file（两次regexp）背后的原因是我可以单独抓取:folder param和:file param，而无需手动拆分它们。

get ':folder/:file', requirements: { file: /.*/, folder: /.*/ } do
  # params[:folder] and params[:file]
end

get ':file', requirements: { file: /.*/ } do
  # params[:file]. [:folder is empty.]
end

^^我想让他们成为一条路线。如果文件夹存在（嵌套），那么它将在文件夹param中获取，否则文件夹将为nil。

Answer 1

确定。我通过尝试和寻找refdocs来找到答案。

get '(:folder/):file', requirements: {  folder: /.*/, file: /.*/ } do

这可以按预期工作。
