Rails - Jan 2006 - Download an Image using Net::HTTP

Hi,

I need to download an image, and I''ve mucked about with Net::HTTP

resp = Net::HTTP.get_response(''www.mydomain.com'',
''/test.jpg'')
f = File.new("test.jpg","w")
f.write(response.body)

And various other combinations using HTTP.get etc. Anyway, I get an 
image, but it looks very psychedelic. This is obviously not the correct 
way. I also don''t want to use Imagemagick for this.

Has anybody done this before?

Joerg

Are you on Windows? If so, you need to use:

f = File.new("test.jpg","wb")

See http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/18810
for a discussion of why, and
http://www.ruby-doc.org/core/classes/IO.html for the documentation of
this mode.

Also you are trying to write response.body into the file when you  
should be using resp.body because resp is the var you used to set up  
the Net::HTTP object
