My favorite two ways to grab the contents of URLs are either OpenURI or Typhoeus   OpenURI because it s everywhere  and Typhoeus because it s very flexible and powerful

I prefer httpclient over Net  HTTP   client   HTTPClient new puts client get content  http   www example com index html     HTTParty is a good choice if you re making a class that s a client for a service  It s a convenient mixin that gives you 90  of what you need  See how short the Google and Twitter clients are in the examples   And to answer your second question  no  I wouldn t put this functionality in a controller--I d use a model instead if possible to encapsulate the particulars  perhaps using HTTParty  and simply call it from the controller

Net  HTTP is built into Ruby  but let s face it  often it s easier not to use its cumbersome 1980s style and try a higher level alternative    HTTP Gem HTTParty RestClient Excon Feedjira   RSS only

Here is the code that works if you are making a REST api call behind a proxy   require  uri  require  net http   proxy host     lt proxy addr gt   proxy port     lt proxy port gt   proxy user     lt username gt   proxy pass     lt password gt    uri   URI parse  https   saucelabs com 80 rest v1 users  lt username gt    proxy   Net  HTTP  Proxy proxy host  proxy port  proxy user  proxy pass   req   Net  HTTP  Get new uri path  req basic auth  lt sauce username gt   lt sauce password gt    result   proxy start uri host uri port  do  http  http request req  end  puts result body
