ruby – 使用字符串到文件名

这很好用：

#!/usr/bin/ruby
require 'httpclient'

http2 = HTTPClient.new
response = http2.get_content("http://example.com/version.ini")

response.each_line do | line |

    http = HTTPClient.new
    my_file = open('file.zip','wb')
    my_file.write(http.get_content("http://example.com/data.zip"))

end

puts "Done."

但这不是：

#!/usr/bin/ruby
require 'httpclient'

http2 = HTTPClient.new
response = http2.get_content("http://example.com/version.ini")

response.each_line do | line |
    puts line # -> file.zip
    http = HTTPClient.new
    my_file = open(line,'wb')
    my_file.write(http.get_content("http://example.com/data.zip"))

end

puts "Done."
