通过带有备用端口的 sftp/scp 进行指南针/sass 远程主题化

本文介绍了通过带有备用端口的 sftp/scp 进行指南针/sass 远程主题化的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在尝试让指南针/sass 观察我本地计算机上的更改，并使用自定义 config.rb 脚本远程反映这些更改.net::sftp 有效，但我的服务器需要自定义 ssh 端口.我找不到任何使 sftp 与备用端口一起工作的 mod，所以我现在尝试 net:scp，问题是我不知道使用 net:scp 上传的正确命令结构，想看看如果有人可以帮助我.这是我的代码:

I am trying to get compass/sass to watch changes on my local computer and reflect those changes remotely using a custom config.rb script. net::sftp works but my server requires a custom ssh port. I couldn't find any mods to make sftp work with an alternate port so im trying net:scp now, the problem is I dont know the proper command structure to upload using net:scp and wanted to see if someone can help me. Here is my code:

  # Require any additional compass plugins here.
require 'net/ssh'
require 'net/scp'

# SFTP Connection Details - Does not support alternate ports os SSHKeys, but could with mods
remote_theme_dir_absolute = '/home2/trinsic/public_html/scottrlarson.com/sites/all/themes/ gateway_symbology_zen/css'
sftp_host = 'xxx.xxx.xxx.xxx' # Can be an IP
sftp_user = 'user' # SFTP Username
sftp_pass = 'password' # SFTP Password

# Callback to be used when a file change is written. This will upload to a remote WP install
on_stylesheet_saved do |filename|
  $local_path_to_css_file = css_dir + '/' + File.basename(filename)

  Net::SSH.start( sftp_host, sftp_user, {:password => sftp_pass,:port => 2222} ) do ssh.scp.upload! $local_path_to_css_file, remote_theme_dir_absolute + '/' + File.basename(filename)
    end
  puts ">>>> Compass is polling for changes. Press Ctrl-C to Stop"
end

#
# This file is only needed for Compass/Sass integration. If you are not using
# Compass, you may safely ignore or delete this file.
#
# If you'd like to learn more about Sass and Compass, see the sass/README.txt
# file for more information.
#


# Change this to :production when ready to deploy the CSS to the live server.
environment = :development
#environment = :production

# In development, we can turn on the FireSass-compatible debug_info.
firesass = false
#firesass = true


# Location of the theme's resources.
css_dir         = "css"
sass_dir        = "sass"
extensions_dir  = "sass-extensions"
images_dir      = "images"
javascripts_dir = "js"


# Require any additional compass plugins installed on your system.
#require 'ninesixty'
#require 'zen-grids'

# Assuming this theme is in sites/*/themes/THEMENAME, you can add the partials
# included with a module by uncommenting and modifying one of the lines below:
#add_import_path "../../../default/modules/FOO"
#add_import_path "../../../all/modules/FOO"
#add_import_path "../../../../modules/FOO"


##
## You probably don't need to edit anything below this.
##

# You can select your preferred output style here (can be overridden via the command line):
# output_style = :expanded or :nested or :compact or :compressed
output_style = (environment == :development) ? :expanded : :compressed

# To enable relative paths to assets via compass helper functions. Since Drupal
# themes can be installed in multiple locations, we don't need to worry about
# the absolute path to the theme from the server root.
relative_assets = true

# To disable debugging comments that display the original location of your selectors. Uncomment:
# line_comments = false

# Pass options to sass. For development, we turn on the FireSass-compatible
# debug_info if the firesass config variable above is true.
sass_options = (environment == :development && firesass == true) ? {:debug_info => true} : {}

运行命令时出现错误:compass watch:

I get an error when I run the command: compass watch:

NoMethodError on line ["17"] of K: undefined method `upload!' for #<Net::SSH::Co
nnection::Session:0x000000036bb220>

推荐答案

我也需要一个解决方案，但没有在任何地方找到任何令人满意的答案.在阅读了 Ruby Net::ssh 文档和 Compass 的一些来源后，这是我将 CSS 和源映射上传到具有非标准端口和强制公钥授权的远程 SSH 服务器的解决方案:

I needed a solution for this too but did not find any satisfying answer anywhere.After reading the Ruby Net::ssh documentation and some source of Compass, this is my solution to upload CSS and sourcemap to a remote SSH server with non-standard port and forced public-key authorisation:

首先确保您安装了所需的 gems

First make sure you have the required gems installed

sudo gem install net-ssh net-sftp

然后将其添加到您的 config.rb

then add this to your config.rb

# Add this to the first lines of your config.rb
require 'net/ssh'
require 'net/sftp'

...
# Your normal compass config comes here
...

# At the end of your config.rb add the config for the upload code
remote_theme_dir_absolute = '/path/to/my/remote/stylesheets'

sftp_host = 'ssh_host' # Can be an IP
sftp_user = 'ssh_user' # SFTP Username

on_stylesheet_saved do |filename|

  # You can use the ssh-agent for authorisation.
  # In this case you can remove the :passphrase from the config and set :use_agent => true.

  Net::SFTP.start(

    sftp_host,
    sftp_user ,
    :port => 10022,
    :keys_only => true,
    :keys => ['/path/to/my/private/id_rsa'],
    :auth_methods => ['publickey'],
    :passphrase => 'my_secret_passphrase',
    :use_agent => false,
    :verbose => :warn

  ) do |sftp|

      puts sftp.upload! css_dir + '/app.css', remote_theme_dir_absolute + '/' + 'app.css'

  end

end

on_sourcemap_saved do |filename|

  # You can use the ssh-agent for authorisation.
  # In this case you can remove the :passphrase from the config and set :use_agent true.

  Net::SFTP.start(
    sftp_host,
    sftp_user ,
    :port => 10022,
    :keys_only => true,
    :keys => ['/path/to/my/private/id_rsa'],
    :auth_methods => ['publickey'],
    :passphrase => 'my_secret_passphrase',
    :use_agent => false,
    :verbose => :warn
  ) do |sftp|

    puts sftp.upload! css_dir + '/app.css.map', remote_theme_dir_absolute + '/' + 'app.css.map'

  end

end

在这对我有用之前，这是相当多的反复试验.一些失败点是:

It was quite some trial and error until this worked for me.Some points of failure were:

如果没有可用的 ssh-agent 连接将失败，直到您设置 :ssh_agent =>;false 明确
如果您不使用 :keys 限制可用密钥，则将一个接一个地尝试所有可用密钥.如果您使用 ssh-agent 并安装了 3 个以上的密钥，则如果您尝试过多对当前连接的服务器无效的密钥，远程服务器将关闭连接.
在任何连接问题上将详细级别设置为 :verbose =>:debug 看看发生了什么.请记住停止 compass watch 并重新启动以确保配置更改适用.

If no ssh-agent is available connection will fail until you set :ssh_agent => false explicitly
If you do not limit the available keys with :keys all available keys will be tried one after another. If you use the ssh-agent and have more than 3 keys installed chanches are high that the remote server will close the connection if you try too much keys that are not valid for the server you currently connect.
On any connection issue set verbosity level to :verbose => :debug to see what is going on. Remember to stop the compass watch and restart to ensure configuration changes apply.
