require 'net/http'
require 'uri'
require 'progressbar'
url = "url with some file"
url_base = url.split('/')[2]
url_path = '/'+url.split('/')[3..-1].join('/')
@counter = 0
Net::HTTP.start(url_base) do |http|
response = http.request_head(URI.escape(url_path))
ProgressBar#format_arguments=[:title, :percentage, :bar, :stat_for_file_transfer]
pbar = ProgressBar.new("file name:", response['content-length'].to_i)
File.open("test.file", 'w') {|f|
http.get(URI.escape(url_path)) do |str|
f.write str
@counter += str.length
pbar.set(@counter)
end
}
end
pbar.finish
puts "Done."
