Rails路由问题，没有路由匹配[GET]“/ api/v1/test_api”

Question

我正在看书Rails 4路和玩路由。以下是我的环境信息：

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

Environment    development

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 

我的问题是，在routes.rb中的match线。据我了解，如果我访问http://localhost:3000/api/v1/test_api，路由规则应该带我到http://localhost:3000/api/test_api_v2。但是当我访问http://localhost:3000/api/v1/test_api时，我得到了以下错误：

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

Rails.root: C:/rails_projects/blog 

我的问题在哪里？我对路由规则的理解有什么问题吗？

编辑，从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)

增加输出我觉得你只需要一个/在你的比赛开始：match "/api/v1/:api"...。你确定:any是一个有效的选择？ Rails Guide只提到:all。
