Question

I’m trying to use the Espresso framework, but I’m having problems in the “hello world” example.

I’ve implemented this code:

require 'e'

class App < E

  def hello
    "Hello World!"
  end

end

App.run

When I run the command ruby hello.rb, I get this:

[2012-08-15 20:54:55] INFO  WEBrick 1.3.1
[2012-08-15 20:54:55] INFO  ruby 1.9.3 (2012-04-20) [i386-mingw32]
[2012-08-15 20:54:55] WARN  TCPServer Error: Normalmente é permitida apenas uma utilização de cada endereço de soquete (protocolo/endereço de rede/porta). - bind(2)
[2012-08-15 20:54:55] INFO  WEBrick::HTTPServer#start: pid=6460 port=80

It seems it is booting up properly but when I try to acess the URL localhost:80/hello, it just doesn’t work. I get a “Not Found: /hello”, and in the console the output is:

[15/Aug/2012:20:56:47] "GET /hello HTTP/1.1" 404 17
- -> /hello

Can anybody tell me why this isn’t working?

Answer 1

Im pretty sure it should be:

require 'e'

class App < E

  map '/' #important

  def hello
    "Hello World!"
  end

end

App.run
