リモートのsftpサイトからxmlをダウンロードし、ファイルの内容をREXMLに読み込んで、データをDBに保存しようとしています。これまでのところ、コードはファイルの読み取りまでであり、f.gets行は次のエラーで失敗します。

/usr/local/lib/ruby/gems/1.9.1/gems/net-sftp-2.0.5/lib/net/sftp/session.rb:846:in `wait_for': Net::SFTP::StatusException (4, "failure") (Net::SFTP::StatusException)

これが私のコードです：

#!/usr/bin/ruby

require 'rubygems'
require 'net/sftp'
require 'rexml/document'

Net::SFTP.start('some.example.host','myuser',:password => 'fake') do |sftp|
    sftp.dir.foreach("/path/to/mydir/") do |xml|
        sftp.file.open("/path/to/mydir/"+xml.name) do |f|
            puts f.gets # < THIS BREAKS IT
        end
    end  
end

コードはダーティで、今のところテストです。リモートディレクトリ内のすべてのファイルを読み取り、各ファイルの最初の行を印刷することを期待しています。

助けてくれてありがとう。

私はあなたが探しているのはこれのどちらかだと思います：

sftp.download!("/path/to/remote", "/path/to/local")

またはこれ

 data = sftp.download!("/path/to/remote")

ドキュメントからこれを取得しました：http：//net-ssh.rubyforge.org/sftp/v2/api/

SFTPユーザーがアクセスできないファイルにアクセスしようとしたときに、同様のエラーが発生しました。
