ROR rails正常启动，但是http://127.0.0.1:3000不能访问的解决办法

D:\aaa>rails s

=> Booting WEBrick

=> Rails 3.2.16 application starting in development on http://0.0.0.0:3000

=> Call with -d to detach

=> Ctrl-C to shutdown server

[2014-10-14 16:14:26] INFO  WEBrick 1.3.1

[2014-10-14 16:14:26] INFO  ruby 1.9.3 (2013-11-22) [i386-mingw32]

[2014-10-14 16:14:26] INFO  WEBrick::HTTPServer#start: pid=12800 port=3000

 

服务启动起来了，但是http://127.0.0.1:3000/不能访问。后台log里的消息是：

ArgumentError (A secret is required to generate an integrity hash for cookie session data. Use config.secret_token = "some secret phrase of at least 30 characters"in config/initializers/secret_token.rb):

 

解决办法：

 rake generate_secret_token

或者

rake secret

原因是需要加密的字符串。
