Ruby on rails WEBrick SSL脚本不启动Rails 4

您好，我一直在遵循本教程，使用WEBrick、Rails 4和RubyMine启用SSL证书

问题是，当我启动此脚本并访问

https://localhost:3443

它只显示文件列表，我想知道我做错了什么这是我的代码谢谢：）：

可能是重复的，谢谢

#!/usr/local/bin/ruby

require 'webrick'
require 'webrick/https'
require 'openssl'

pkey = cert = cert_name = nil

begin

pkey = OpenSSL::PKey::RSA.new(File.open('ssl/server.key').read)

cert = OpenSSL::X509::Certificate.new(File.open('ssl/server.crt').read)

end

s=WEBrick::HTTPServer.new(

:Port => 3443,

:Logger => WEBrick::Log::new($stderr, WEBrick::Log::DEBUG),

:DocumentRoot => "./public",

:SSLEnable => true,

:SSLVerifyClient => OpenSSL::SSL::VERIFY_NONE,

:SSLCertificate => cert,

:SSLPrivateKey => pkey,

:SSLCertName => [ [ "CN",WEBrick::Utils::getservername ] ]
)

s.start
