功能很简单，用 ruby 脚本将一个目录内的文件利用 http post 发给服务器端，然后服务器端将接收到的文件保存起来 ruby 脚本

require "net/http"
require "find"
require "rest_client"

file_path = "/home/tiny/log"

file_list = []
file_hash = {}
Find.find(file_path) do |path|
  next if File.ftype(path) == "directory"
  file_list << path
end

file_list.each do |file|
  file_hash[file] = File.new(file, "rb")
end

RestClient.post("http://localhost:4567/uploads", :info => file_hash)

服务器端使用的 Sinatra

get '/' do
  "main"
end

post '/uploads' do
  Dir.mkdir(File.join(Dir.home, "assets")) if !File.exist?(File.join(Dir.home, "assets"))

  puts params[:info].class
  puts params[:info].size
  puts params[:info]

  params[:info].each do |file_name, file|
    puts file_name.class
    puts file.class
  end

end

当取消 params[:info] 循环的时候，

!!
