SCP 未成功完成 (1) 尝试使用 ruby​​ 从 Windows 上传到 Ubuntu 时出错

Question

我的代码

IMAGE_DIR = 'D:\File_Server\Nisa_Costcutter\Master Nisa CC Logos'

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

def scopy_file(file)
  puts "Transferring #{file.path}"
  Net::SCP.upload!('192.168.254.5', 
                   'passenger', 
                    file, 
                    '/var/www/pinpointlms.co.uk/shared/logos', 
                    :ssh => {password: '*****'})
end

puts "Starting Upload"

Dir.foreach(IMAGE_DIR) do |name|
  if name.length > 4 && name[-4..-1].upcase == '.BMP'

    filename=name.strip()
    file = File.new(File.join(IMAGE_DIR, filename))

    if (Time.now - file.mtime) > 86400
        scopy_file(file) 
    end


  end


end
puts "End of Transfer"

我正在尝试使用 Ruby 将一些文件从 Windows 机器复制到 Ubuntu 机器，但我得到以下输出：

我是一名 ruby​​ 初学者，因此非常感谢您对如何进一步调试此代码提供的任何帮助。

谢谢

Answer 1

您可能没有用户访问权限来在您的 Ubuntu 服务器上的给定目录“/var/www/pinpointlms.co.uk/shared/logos”中上传（写入）该文件。

尝试在不提供完整路径的情况下保存它，因此它最终位于 Ubuntu 服务器上用户的主目录中。如果这可行，那么您的问题与服务器上的用户权限有关。

Answer 2

如果它对其他人有帮助，我在尝试将文件上传到尚不存在的路径时遇到与此完全相同的错误。来自 shell 的 scp 将允许您执行此操作，但 Net::SCP 将因此错误而失败。

即

scp "my.file" "/foo/bar/"

如果 /foo 存在但 /foo/bar/ 不存在，scp 将创建 /foo/bar 并将您的文件放在那里（假设权限允许您这样做）。

但是 - 在相同的情况下 - 这将失败并出现问题中给出的错误

scp.upload!(my_file, "/foo/bar/")

我找到的唯一解决方案是首先在本地创建您想要的路径，然后使用 :recursive 选项上传，如下所示：

scp.upload!("bar/", "/foo" :recursive => true)

其中 ./bar 包含 my_file。
