当我为Rails应用程序运行服务器时,我看到了一件奇怪的事情.这是日志：
Jatins-MacBook-Pro: silverSpoon$rails s => Booting Thin => Rails 3.2.8 application starting in development on http://0.0.0.0:3000 => Call with -d to detach => Ctrl-C to shutdown server >> Thin web server (v1.5.0 codename Knife) >> Maximum connections set to 1024 >> Listening on 0.0.0.0:3000,CTRL+C to stop Started GET "/app/update-progress" for 127.0.0.1 at 2013-05-19 15:04:56 +0530 Connecting to database specified by database.yml ActionController::RoutingError (No route matches [GET] "/app/update-progress"): actionpack (3.2.8) lib/action_dispatch/middleware/debug_exceptions.rb:21:in `call' actionpack (3.2.8) lib/action_dispatch/middleware/show_exceptions.rb:56:in `call' railties (3.2.8) lib/rails/rack/logger.rb:26:in `call_app' railties (3.2.8) lib/rails/rack/logger.rb:16:in `call' actionpack (3.2.8) lib/action_dispatch/middleware/request_id.rb:22:in `call' rack (1.4.1) lib/rack/methodoverride.rb:21:in `call' rack (1.4.1) lib/rack/runtime.rb:17:in `call' activesupport (3.2.8) lib/active_support/cache/strategy/local_cache.rb:72:in `call' rack (1.4.1) lib/rack/lock.rb:15:in `call' actionpack (3.2.8) lib/action_dispatch/middleware/static.rb:62:in `call' railties (3.2.8) lib/rails/engine.rb:479:in `call' railties (3.2.8) lib/rails/application.rb:223:in `call' rack (1.4.1) lib/rack/content_length.rb:14:in `call' railties (3.2.8) lib/rails/rack/log_tailer.rb:17:in `call' thin (1.5.0) lib/thin/connection.rb:81:in `block in pre_process' thin (1.5.0) lib/thin/connection.rb:79:in `catch' thin (1.5.0) lib/thin/connection.rb:79:in `pre_process' thin (1.5.0) lib/thin/connection.rb:54:in `process' thin (1.5.0) lib/thin/connection.rb:39:in `receive_data' eventmachine (1.0.1) lib/eventmachine.rb:187:in `run_machine' eventmachine (1.0.1) lib/eventmachine.rb:187:in `run' thin (1.5.0) lib/thin/backends/base.rb:63:in `start' thin (1.5.0) lib/thin/server.rb:159:in `start' rack (1.4.1) lib/rack/handler/thin.rb:13:in `run' rack (1.4.1) lib/rack/server.rb:265:in `start' railties (3.2.8) lib/rails/commands/server.rb:70:in `start' railties (3.2.8) lib/rails/commands.rb:55:in `block in <top (required)>' railties (3.2.8) lib/rails/commands.rb:50:in `tap' railties (3.2.8) lib/rails/commands.rb:50:in `<top (required)>' script/rails:6:in `require' script/rails:6:in `<main>' Rendered /Users/silverSpoon/.rvm/gems/ruby-1.9.3-p194@fbTracker/gems/actionpack-3.2.8/lib/action_dispatch/middleware/templates/rescues/routing_error.erb within rescues/layout (2.3ms)
然后,请求反复进行.请指导我找到此类行为的原因以及如何解决此问题.
rake：routes的输出是：
bash-3.2$rake routes
trackers /trackers(.:format) tracker#index
root / home#index
users POST /users(.:format) users#create
edit_user GET /users/:id/edit(.:format) users#edit
user GET /users/:id(.:format) users#show

解决方法
您的应用没有到/ app / update_progress的路线.所以它是下面的一个在你的应用程序中调用它：
>你的应用程序中的Javascript代码(你有机会使用this Bootstrap Progressbar吗？)
要测试这是否是问题的根源 – 打开Chrome开发者工具并转到Network panel.现在打开您的应用程序localhost：3000.如果您在此网络选项卡中看到对localhost：3000 / app / update_progress的一致调用,则表示您的应用程序正在从Javascript触发这些请求.现在,您需要搜索代码库以找出javascript代码的位置.它可能在你已下载的某个jquery扩展中.你可以create a breakpoint in Javascript whenever an Ajax request is made到/ app / update_progress.
> chrome / firefox扩展
要解决此问题,请以隐身模式打开Chrome / Firefox(通常会禁用所有扩展程序),然后打开您的应用程序.如果您仍然看到/ app / update_progress的匹配,那么很可能它不是导致问题的扩展.
>你正在使用的一些外部宝石
如果上面两个没有实现,那么发布您的Gemfile.
