Ruby Sinatra Webservice running on localhost:4567 but not on IP

Question

I have a ruby(using sinatra) webservice on windows 7 32 bit OS. Its running on port 4567. Its working fine when I use localhost:4567 but when I replace localhost with the local ip of my machine say, 192.168.103.99:4567 it doesn't work, and fails to connect. I have already disabled the firewall, by-pass proxy and added port 4567 to exception, still no luck.

What might be the issue ?

Answer 1

以下为我工作。

ruby app.rb -o 0.0.0.0

Answer 2

When using the built-in server through the run! if app_file == $0 run! if app_file == $0 check, Sinatra's doc explains that set :bind, '0.0.0.0' is required to make the interface available outside the localhost layer.

It is not required to use a custom IP address or a reverse DNS (mydomain.com…): '0.0.0.0' is the legit value expected by Sinatra , which will be interpreted correctly.

Therefore, a minimal, self-contained Sinatra application made available on all interfaces, not only localhost , would be:

require 'sinatra/base'

class MyApp < Sinatra::Base
  set :bind, '0.0.0.0'

  get '/' do
    'Hello World'
  end

  run! if app_file == $0
end

Answer 3

要设置服务器主机名或 IP 地址，请使用sinatra 设置绑定，例如

set :bind, '192.168.103.99'

Answer 4

this

require 'rubygems'
require 'sinatra'
require "dbi"

set :bind, '192.168.200.185'
get '/' do
    'hello word'
end
