Although there is a Twitter-gem to talk to the Twitter webservices you can save that dependency. The interface of the Twitter update service is very simple so you can update Twitter accounts very easily without a library.
Here is the code I use for sending updates of my little weather station to my twitter account. You get the response from the Twitter service as a Ruby hashtable for easy access.
#!/usr/bin/ruby
require 'net/http'
require 'uri'
def sendtwitter(userid,password,status)
url=URI.parse('http://twitter.com/statuses/update.json')
req=Net::HTTP::Post.new(url.path)
req.basic_auth(userid, password)
req.set_form_data({'status'=> status},';')
res=Net::HTTP.new(url.host,url.port).start {|http| http.request(req)}
case res
when Net::HTTPSuccess, Net::HTTPRedirection
null=nil; jsonobj = eval(res.body.gsub(/(["'])\s*:\s*(['"0-9tfn\[{])/){"#{$1}=>#{$2}"})
jsonobj
else
res.error!
end
end
puts sendtwitter('userid','password','Teststatus')['id']
require 'net/http'
require 'uri'
def sendtwitter(userid,password,status)
url=URI.parse('http://twitter.com/statuses/update.json')
req=Net::HTTP::Post.new(url.path)
req.basic_auth(userid, password)
req.set_form_data({'status'=> status},';')
res=Net::HTTP.new(url.host,url.port).start {|http| http.request(req)}
case res
when Net::HTTPSuccess, Net::HTTPRedirection
null=nil; jsonobj = eval(res.body.gsub(/(["'])\s*:\s*(['"0-9tfn\[{])/){"#{$1}=>#{$2}"})
jsonobj
else
res.error!
end
end
puts sendtwitter('userid','password','Teststatus')['id']
