FasterCSV:读取远程CSV文件

我似乎无法让这个工作.我想从不同的Web服务器中提取CSV文件以读取我的应用程序.这就是我想要的方式:

url = 'http://www.testing.com/test.csv'
records = FasterCSV.read(url, :headers => true, :header_converters => :symbol)

但这不起作用.我试过谷歌搜索,我想出的就是这个摘录:实用的红宝石宝石

所以,我尝试修改如下:

require 'open-uri'
url = 'http://www.testing.com/test.csv'
csv_url = open(url)
records = FasterCSV.read(csv_url, :headers => true, :header_converters => :symbol)

...我得到一个can't convert Tempfile into String错误(来自FasterCSV宝石).

谁能告诉我如何使这项工作？

require 'open-uri'
url = 'http://www.testing.com/test.csv'
open(url) do |f|
  f.each_line do |line|
    FasterCSV.parse(line) do |row|
      # Your code here
    end
  end
end
