ruby 下载文件到本地

require 'open-uri'

def downLoadJpg(fileName, uri)
	data = open(uri, 'User-Agent' => 'ruby'){|f| f.read} 
	
	file = File.new fileName, 'w+'
	file.binmode 
	file << data 
	file.flush 
	file.close
end

doc.search('//html/body/card_list/card').each do |card|
		puts(card.text)
		t = card.attribute("t")
		cid = card.attribute("cid")
		puts(t)
		puts(cid)

		fileName = "e:/" + t + ".jpg"
		downLoadJpg(fileName, card.text)
	end

出现错误：

引用

ruby/1.9.1/open-uri.rb:346:in `open_http': 403 Forbidden (OpenURI::HTTPError)

def downLoadJpg(fileName, uri)
	data = open(URI::encode(uri),  "User-Agent" => "Ruby/#{RUBY_VERSION}"){|f| f.read} 
	
	file = File.new fileName, 'w+'
	file.binmode 
	file << data 
	file.flush 
	file.close
end

主要是我在循环里面不断的去打开同一服务器上的不同的文件，就被禁止掉了
