Hello, today we make simple Telegram bot on Ruby. We’ll find user (or sites) by IP address and will use ip_info gem. Detail information about using gem you can read in github page

Create Telegram bot

Before of all you must create new telegram bot. It’s very simple, you can read more about it in official documentation.

Simple instruction:

Start dialog with @BotFather
Use /newbot for creating new bot
Choose name and login for bot
Get API KEY for further actions

Create and configure new bot

Write to @BotFather

I choose name IpInfoBot, but now we must choose login name.

After of all changes we have our API KEY and working bot.

For our bot we make simple Gemfile and we’ll use Telegram-bot-ruby it’s pretty awesome.

source 'https://rubygems.org'

gem 'telegram-bot-ruby'
gem 'ip_info'

Simple usage of this gem:

require 'rubygems'
require 'telegram/bot'
require 'ip_info'

token = '152628097:AAH8T0o6Aq9bKQCkS_fI3-36Gl5-XUADrOs'

Telegram::Bot::Client.run(token) do |bot|
  bot.listen do |message|
    case message.text
    when '/start'
      bot.api.send_message(chat_id: message.chat.id,
                          text: "Hello, #{message.from.first_name}")
    end
  end
end

If we’ll send /start message for our bot we have response: Hello, <your_name>

Notice: Always use message.chat.id for sending message, because your bot can used in group dialogs

I want make comands like /city <ip_address>. But I relly don’t know how to get <ip_address> from message in right way. For getting address form message we’ll use regex. Make simple method:

def get_address_form(message)
  message[/([\d.]+|(?:https?:\/\/)?(?:[\w]+\.)?[\w]+\.[\w]+)/]
end

But we have /cite 000.000.000.000 message. Change our ‘engine’ of our bot:

token = '152628097:AAH8T0o6Aq9bKQCkS_fI3-36Gl5-XUADrOs'
@ip_info = IpInfo::API.new(api_key: ENV["IP_INFO_KEY"])

Telegram::Bot::Client.run(token) do |bot|
  bot.listen do |message|
    case message.text
    when '/start'
      bot.api.send_message(chat_id: message.chat.id,
                          text: "Hello, #{message.from.first_name}")
    when /\/city [\w\W]+/
      bot.api.send_message(chat_id: message.chat.id,
                          text: get_info(get_address_form(message.text), 'city') )
    when /\/country [\w\W]+/
      bot.api.send_message(chat_id: message.chat.id,
                          text: get_info(get_address_form(message.text), 'country') )
    end
  end
end

and make simple method for sending request to ipifodb site:

def get_info(address, type)
  return 'Error: Address is invalid' unless address

  data = ''
  @ip_info.lookup(address, type: type).map do |e|
    data << e.first.to_s.gsub(/_/, ' ').capitalize + ': ' + e.last + "\n"
  end
  data
end

We convert result of using ip_info gem, because we have result:

> max-si-m.github.io git:(master)  irb
irb(main):001:0> require 'ip_info'
=> true
irb(main):002:0> ip_info = IpInfo::API.new(api_key: ENV['IP_INFO_KEY'])
=> #<IpInfo::API:0x007ff2ebc16250
@api_key="3be331437ac07643ed662ec1fad76ed57d125be3184204864f8d3029f5b8aaa2">
irb(main):003:0> ip_info.lookup('11.34.66.78', type: 'city', time_zone:
true)
=> {:status_code=>"OK", :status_message=>"", :ip_address=>"11.34.66.78",
:country_code=>"US", :country_name=>"United States",
:region_name=>"Ohio", :city_name=>"Columbus", :zip_code=>"43218",
:latitude=>"39.9664", :longitude=>"-83.0128", :time_zone=>"-05:00"}

Set comands for our bots:

And now we have fully working bot. Try in work our bot:

Find user by IP:

Find info about site:

Find country of site:

Summary

We make simple bot for Telegram, it’s not hard but interesting. If you will try bot and it’s not available, maybe I was delete it :) If you have another way to get address from message send pull request or send message.
