Prowl

Prowl is awesome. Growl notifications can be forwarded to your iPhone.

But you can get notifications from anywhere. A Perl script is included, but that didn’t work on my server. So I wrote one in Ruby:

 1#! /usr/bin/ruby
 2
 3# A ruby class for sending notifications to Prowl.
 4
 5require 'uri'
 6require 'net/http'
 7require 'net/https'
 8
 9class String
10  def urlencode
11    gsub( /[^a-zA-Z0-9\-_\.!~*'()]/n ) {|x| sprintf('%%%02x', x[0]) }
12  end
13end
14
15class Hash
16  def urlencode
17    collect { |k,v| "#{k.to_s.urlencode}=#{v.to_s.urlencode}" }.join('&')
18  end
19end
20
21class Prowler
22  def initialize user, pass
23    @url = URI.parse('https://prowl.weks.net/api/add_notification.php')
24    @username = user
25    @password = pass
26    
27    @http = Net::HTTP.new(@url.host, @url.port)
28    @http.use_ssl = true
29  end
30
31  def send_notification app, evt, desc
32    
33
34    options = {
35      'application' => app,
36      'event' => evt,
37      'description' => desc
38    }
39    
40    req = Net::HTTP::Get.new("#{@url.path}?#{options.urlencode}")
41    req.basic_auth @username, @password
42    @http.request(req)
43  end
44
45end
46
47# How to use?
48# p = Prowler.new('username', 'password')
49# p.send_notification('App','Event','Desc')
