XMPP4R 介绍
XMPP4R是一个XMPP/Jabber的Ruby类库。它的目标是提供开发Jabber相关应用程序或者Ruby脚本的完整框架。
安装方法：gem install xmpp4r
示例代码：
# Send a message to a friend, asking for authorization if necessary:
im = Jabber::Simple.new("user@example.com", "password")
im.deliver("friend@example.com", "Hey there friend!")
# Get received messages and print them out to the console:
im.received_messages { |msg| puts msg.body if msg.type == :chat }
# Send an authorization request to a user:
im.add("friend@example.com")
# Get presence updates from your friends, and print them out to the console:
# (admittedly, this one needs some work)
im.presence_updates { |update|
from = update[0].jid.strip.to_s
status = update[2].status
presence = update[2].show
puts "#{from} went #{presence}: #{status}"
end
# Remove a user from your contact list:
im.remove("unfriendly@example.com")
# See the Jabber::Simple documentation for more information.
