我正在尝试从ftp站点检索文件(.csv)并将它们全部保存在同一文件夹中。我的代码如下所示:
#! /usr/bin/ruby
require 'logger'
require 'fileutils'
require 'net/ftp'
require 'rubygems'
require 'mysql2'
require 'roo'
require 'date'
# logging setup
log = Logger.new("/path_to_logs/ftp_log.log", 10, 1024000)
log.level = Logger::INFO
export_ftp_path = '/Receive/results/'
export_work_path ='/Users/pierce/results_exports/'
Net::FTP.open('host', 'username', 'password') do |ftp|
log.info("Logged into FTP")
ftp.passive = true
ftp.chdir("#{export_ftp_path}")
ftp.list.each do |file|
log.info("Found file #{file}")
new_file = file[56..115] #take part of the file name and remove spaces and periods
new_file = new_file.gsub(/[.]+/, "")
new_file = new_file.gsub(/\s/, "0")
ftp.gettextfile(file,"#{new_file}")
log.info("Downloaded file #{new_file}")
end
end
这是我收到的错误:
/Users/pierce/.rbenv/versions/1.9.2-p290/lib/ruby/1.9.1/net/ftp.rb:560:in `initialize': No such file or directory - (Errno::ENOENT)
from /Users/pierce/.rbenv/versions/1.9.2-p290/lib/ruby/1.9.1/net/ftp.rb:560:in `open'
from /Users/pierce/.rbenv/versions/1.9.2-p290/lib/ruby/1.9.1/net/ftp.rb:560:in `gettextfile'
from ftp_test.rb:44:in `block (2 levels) in <main>'
from ftp_test.rb:33:in `each'

from /Users/pierce/.rbenv/versions/1.9.2-p290/lib/ruby/1.9.1/net/ftp.rb:116:in `open'
正如所建议的,这里是我对puts文件的值,并放置new_file。
file = -rwxr-xr-x 1 1130419 114727 9546 May 17 08:11 results_Wed. 16 May 2012.csv
new_file = results_Wed0230May02012csv
有关在gettextfile或我的脚本中更改内容以正确保存文件的任何建议吗?
答案 0 :(得分:1)
当您只需要目录中的文件列表时,应该使用nlst
而不是list
。 list
的输出需要正确解析。
当您请求文件时,它必须是原始文件名,包括所有空格。保存文件时,它可以是您想要的任何内容(包括空格或不包含空格)。该错误是因为您请求了错误的文件。请改用您的案例nlst
。它会使它变得更容易(不需要转换或解析)。
