我有一个小问题:我尝试使用 SCP 和 Ruby 将文件上传到使用私钥的服务器。代码如下所示:

  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目的,并且我收到以下日志错误:

你能指出这里可能有什么问题吗?在这个阶段,我的 Ruby 经验非常有限。

似乎现在这是可能的。根据net-scp 文档,您可以使用 Net::SSH 会话来执行scp命令。结合这个关于在 Ruby 中使用私钥进行身份验证的答案:

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

简要查看文档表明它不接受 ssh 密钥选项,因为您正在传递。但假设你是对的,我在这方面是错的,

在没有看到您传递给 transfer_file 的值以及存储在@folder 中的内容的情况下,我只能猜测,但假设它们都是文件对象,您无法连接这些对象。你必须抓住他们的路径属性。您可能想要记录这两个变量的值以确保您获得了路径。你也可能有更好的运气使用 ruby"#{}"​​ 方法来连接字符串参数,在这里再次猜测但是

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

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