I''m looking at the documentation:
http://ruby-doc.org/stdlib-2.0/libdoc/net/http/rdoc/Net/HTTP.html
And I notice two uses of Net::HTTP. Both are using GET requests. But
what''s the difference? When to use which?
Net::HTTP.start(uri.host, uri.port) do |http|
request = Net::HTTP::Get.new uri
response = http.request request # Net::HTTPResponse object
end
uri = URI(''http://example.com/index.html'')
res = Net::HTTP.get_response(uri)

If I''m only getting one thing and then carrying on with it with no need for using that connection again, I''ll use the second form. But again, this is only a heuristic, and not definitive. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

The long form allows you to pipeline requests, set more options on the request (eg headers etc.) but a lot of the time you just want to grab the content from a url and don''t need all the ceremony Fred> Net::HTTP.start(uri.host, uri.port) do |http| > request = Net::HTTP::Get.new uri > > response = http.request request # Net::HTTPResponse object > end > > > > uri = URI(''http://example.com/index.html'') > res = Net::HTTP.get_response(uri) >-- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
