shadowsocks-auth nodejs client

ss.coffee

SS_PREFIX = 'ss:'

#
# user
#   name:  shadowsocks 的用户名
#   password: shadowsocks 的密码
#   method: shadowsocks 的加密方法
#   limit: 最大流量
#
# shadowsocks 加密方法有:
#   aes-128-cfb, aes-192-cfb, aes-256-cfb, bf-cfb, cast5-cfb, des-cfb, rc4
#
# 注意 redis 要与 shadowsocks-auth 同一个才有效
#

    catch e
      callback e

  # 获取用户流量使用的列表
  # opts
  #   name
  #   year: 2014
  #   month
  #   day
  #   member
  #   start: 0
  #   stop: 20
  #
  # member 为 host:port 或者 total
  # 当 member 存在时只返回流量值
  #
  opts.year = opts.year or '2014'
  key = "#{SS_PREFIX}flow:#{opts.name}:#{opts.year}"
  key = "#{key}:#{opts.month}" if opts.month
  key = "#{key}:#{opts.day}" if opts.day

  return client.zscore key, member, callback if opts.member
  opts.start = opts.start or 0
  opts.stop = opts.stop or 20
  client.zrevrange key, opts.start, opts.stop, 'withscores', callback

how can i use it?

// install requirement
// npm install redis
var ss = require('ss');
// create a new user.
var user = {
  name: 'name',
  password: 'password',
  method: 'aes-128-cfb',
  limit: 1 ＊ 1024 ＊ 1024 ＊ 1024
};

ss.set_user(user, function() {
   console.log('create user done');
});

现在还能用吗？
