Ruby net / ftp代码由于错误而无法放入文件 [英] Ruby net/ftp code failing to PUT a file because of error

问题描述

我有这个失败的基本代码：

  ftpconfighash = open（＃{RAILS_ROOT} / config / ftp。 yml）{| f | YAML.load（f）} 
 config = ftpconfighash [12345] 
 
 ftp = Net :: FTP :: new（config [host]）
 ftp.login（ config [username]，config [password]）
 
 dir + =/除非配置[dir]。或者config [dir]。ends_with？（/）
 remotename = File.basename（filename）
 remotename = dir + remotename，除非dir.blank？ 
 
如果File.binary？（文件名）
放置将二进制文件＃{文件名}放置到＃{remotename}
 ftp.putbinaryfile（文件名，远程名称）
 else 
将将ASCII文件＃{文件名}存入＃{remotename}
 ftp.puttextfile（filename，remotename）
 end 
 ftp.close 
  

我已验证我可以ftp到服务器并手动输入文件。我还使用irb逐行浏览代码。我使用XML文件作为测试，所以ftp.puttextfile是失败的行。这是错误：

  Net :: FTPPermError：500无效的PORT命令。 
  

我不明白。我已经证实我确实可以放这个文件，但是我不能用这段代码来完成。

我将ftp.debug_mode设置为true，这是输出来自ftp.puttextfile命令：

  put：TYPE A 
 get：200类型设置为A. 
 put：PORT 10,0,1,20,198,170 
 get：500无效的PORT命令。 
 Net :: FTPPermError：500无效的PORT命令。

Ruby似乎试图运行一个命令FTP服务器不理解：

  Port 10,0,1,20,198,170 
  

有没有办法抑制这个命令，或者我缺少其他的东西？

  ftp = Net :: FTP :: new（ config [host]）
 ftp.login（config [username]，config [password]）
 
 ftp.passive = true 
  

I have this basic code that is failing:

  ftpconfighash = open("#{RAILS_ROOT}/config/ftp.yml") {|f| YAML.load(f) }
  config = ftpconfighash[12345]

  ftp = Net::FTP::new(config["host"])
  ftp.login(config["username"], config["password"])

  dir += "/" unless config["dir"].blank? or config["dir"].ends_with?("/")
  remotename = File.basename(filename)
  remotename = dir + remotename unless dir.blank?

  if File.binary?(filename)
    puts "PUTting binary file #{filename} to #{remotename}"
    ftp.putbinaryfile(filename, remotename)
  else
    puts "PUTting ASCII file #{filename} to #{remotename}"
    ftp.puttextfile(filename, remotename)
  end
  ftp.close

I have verified that I can ftp to the server and PUT a file by hand. I have also used irb to walk through the code line-by-line. I am using an XML file as a test, so the "ftp.puttextfile" is the line that is failing. Here is the error:

Net::FTPPermError: 500 Invalid PORT Command.

I don't understand. I have verified that I can indeed put this file, but I just can't do it with this code.

I set ftp.debug_mode to true, and this is the output from the ftp.puttextfile command:

put: TYPE A
get: 200 Type set to A.
put: PORT 10,0,1,20,198,170
get: 500 Invalid PORT Command.
Net::FTPPermError: 500 Invalid PORT Command.

It looks like Ruby is trying to run a command that the FTP server doesn't understand:

PORT 10,0,1,20,198,170

Is there some way to suppress that command, or am I missing something else?

解决方案

Try using passive ftp:

ftp = Net::FTP::new(config["host"])
ftp.login(config["username"], config["password"])

ftp.passive = true
