I'd like to set --limit-rate
option for downloads done by Curb gem (ruby interface to curl).
In curl:
curl --limit-rate 10K http://server/large_file.rar
For downloads by Curb I have this code (plus progressbar, but that's not relevant to this question):
require 'rubygems'
require 'curb'
request = 'http://server/large_file.rar'
filename = 'large_file.rar'
f = open(filename, 'wb')
c = Curl::Easy.new(request) do |curl|
curl.on_body { |d| f << d; d.length }
end
c.perform
f.close
How do I set --limit-rate
option in this script? As long as I can tell, there's no easy way (I'开发者_JS百科ve already read rdoc and done some googling).
You would do this by setting CURLOPT_MAX_RECV_SPEED_LARGE
in libcurl
. Through the curb
API, you would do:
c = Curl::Easy.new(request) do |curl|
curl.set(:max_recv_speed_large, download_limit)
curl.on_body { |d| f << d; d.length }
end
Where download_limit
is an integer for the maximum download rate in bytes per second.
