define_method
可以帮助我们动态的,快速的定义多个方法;比如有这样一个类:
class Post
attr_accessor :title, :content, :state
def initialize(title, content, state = :draft)
@title, @content, @state = title, content, state

master_secret = '57c45646c772983fede7c455' #必填,每个应用都对应一个masterSecret | |
# 保存离线的时长。秒为单位。最多支持10天(864000秒)。 | |
# 0 表示该消息不保存离线。即:用户在线马上发出,当前不在线用户将不会收到此消息。 | |
# 此参数不设置则表示默认,默认为保存1天的离线消息(86400秒)。 |

SSHPass is a tiny utility, which allows you to provide the ssh password without using the prompt. This will very helpful for scripting. SSHPass is not good to use in multi-user environment. If you use SSHPass on your development machine, it don't do anything evil.
apt-get install sshpass
