如何使用Ruby和私钥执行SCP?

scp key ruby

这里有一个小问题:我尝试使用scp和ruby将文件上载到使用私钥的服务器上。代码如下:

  def transfer_file(source_file, destination_file)
     $log.info("ScpDP: Key=#{@key}")
     Net::SCP.start(@host, @userName, :keys => @key ) do |scp|
       scp.upload!(source_file,@folder + destination_file, :ssh => @key)
     end
  end

但是,有一些问题,而不是私钥,因为我们将它用于日常用途,我得到以下日志错误:

I, [2010-08-24T11:21:27.247847 #14310]  INFO -- : ScpDP: Key=/home/myself/.ssh/id_rsa

你能指出这里可能有什么问题吗?在这个阶段,我对Ruby的体验非常有限。

简要地看一下 this 文档表明它不接受ssh密钥选项,因为您正在传递。但假设你是对的,而我在这方面是错的,

在看不到传递给传输文件的值和存储在@folder中的值的情况下,我只能猜测,但假设它们都是文件对象,则无法连接这些对象。您必须获取它们的路径属性。您可能需要记录这两个变量的值,以确保获得路径。使用红宝石也会有更好的运气。 "#{}" 方法来concat字符串参数,这里再次猜测,但是

path = "#{@folder.path}/#{destination_file.path}" #=> "my_folder/destination_folder

和

scp.upload!(source_file,path, :ssh => @key)

看来这是可能的。根据 net-scp docs ,可以使用net::ssh会话执行 scp 命令。结合 this answer 关于使用Ruby中的私钥进行身份验证:

require 'net/ssh'
require 'net/scp'

ssh_private_keys = ['ssh-rsa AAAAB3NzaC1yc2EAAA', 'ssh-rsa AAAAB3NzaC1yc2EAAA']
Net::SSH.start(hostname, username, key_data: ssh_private_keys, keys_only: true) do |ssh|
  ssh.scp.upload!(source_file, destination_file)
end
