Rails路由問題，沒有路由匹配[GET]「/ api/v1/test_api」

Question

我正在看書Rails 4路和玩路由。以下是我的環境信息：

C:\rails_projects\blog>rake about 
About your application's environment 
Ruby version    1.9.3-p374 (i386-mingw32)

C:\rails_projects\blog> 

我的routes.rb文件是：

Rails.application.routes.draw do 
    resources :posts 
    root "posts#index" 

    match "api/v1/:api" => redirect(status: 302) {|params| "/api/" + params[:api] + "_v2"}, via: :any 
end 

我的問題是，在routes.rb中的match線。據我瞭解，如果我訪問http://localhost:3000/api/v1/test_api，路由規則應該帶我到http://localhost:3000/api/test_api_v2。但是當我訪問http://localhost:3000/api/v1/test_api時，我得到了以下錯誤：

No route matches [GET] "/api/v1/test_api" 

Rails.root: C:/rails_projects/blog 

我的問題在哪裏？我對路由規則的理解有什麼問題嗎？

編輯，從rake routes

C:\rails_projects\blog>rake routes 
    Prefix Verb URI Pattern    Controller#Action 
    posts GET /posts(.:format)   posts#index 
      POST /posts(.:format)   posts#create 
new_post GET /posts/new(.:format)  posts#new 
edit_post GET /posts/:id/edit(.:format) posts#edit 
    post GET /posts/:id(.:format)  posts#show 
      PATCH /posts/:id(.:format)  posts#update 
      PUT /posts/:id(.:format)  posts#update 
      DELETE /posts/:id(.:format)  posts#destroy 
    root GET /      posts#index 
      ANY /api/v1/:api(.:format) redirect(302)

增加輸出我覺得你只需要一個/在你的比賽開始：match "/api/v1/:api"...。你確定:any是一個有效的選擇？ Rails Guide只提到:all。
