Question

我在这里遇到一个小问题：我尝试使用私钥将使用SCP和Ruby的文件上传到服务器。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，并且我收到以下日志错误：

请指出这里可能有什么问题？我现阶段的Ruby经验非常有限。

简要介绍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，那个部分我错了，

没有看到传递给transfer_file的值和@folder中存储的内容，我只能猜测，但假设它们都是文件对象，则无法连接对象。你必须抓住他们的路径属性。您可能希望记录这两个变量的值以确保获得路径。你可能还有更好的运气使用ruby "#{}"方法来连接字符串参数，再次在这里猜测但是

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

和

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

Answer 2

似乎现在可以了。根据{{3}}，您可以使用Net :: SSH会话来执行scp命令。结合net-scp docs关于在Ruby中使用私钥进行身份验证：

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

如何用Ruby和私钥做SCP？
