在 上一篇教程中, 我们创建了自动回复消息的机器人,当用户发送消息"Hello,World!"时，机器人会自动回复同一条消息!
按本篇教程后学习后完成后，你的机器人将会接受用户发送过来的加密货币，然后立即转回用户。下面是全部源代码，创建一个websocket_mixin_bot.rb试一下吧！

你好，我的币!
在工程目录下，执行 ruby websocket_mixin_bot.rb
ruby websocket_mixin_bot.rbwenewzha:mixin_labs-ruby-bot wenewzhang$ ruby websocket_mixin_bot.rb
[:open]
[:message]
{"id"=>"1003b2b5-b8e4-4b54-bd03-983c61f64869", "action"=>"LIST_PENDING_MESSAGES"}如果控制台出现 "LIST_PENDING_MESSAGES"字样, 连接到mixin.one成功了，正在侦听用户发送消息给它!
按帮助来操作,发送消息得到相应的支付提示
- 1 机器人回复 APP_CARD 支付链接.
- 2 机器人回复 APP_BUTTON_GROUP 支付链接.
- ? or help : 显示帮助
点击上面的链接，将会弹出一个窗口，输入你的密码，将支付币给机器人!
Mixin Messenger支持的消息类型
如下图所示，用户点击支付链接，输入密码，支付0.01 EOS给机器人，机器人马上返还给用户！
亲爱的开发者，你也可以从消息控制面板里，点击转帐，直接将币转给机器人！它还是一样的立即返还！
源代码解释
if jsmsg["data"]["category"] == "SYSTEM_ACCOUNT_SNAPSHOT"
jsdata = JSON.parse (Base64.decode64(jsmsg["data"]["data"]))
p jsdata["amount"]
if jsdata["amount"].to_f > 0
p "The Bot got coins:" + jsdata["amount"]
transInfo = MixinBot.api.create_transfer(MixinBot.api.encrypt_pin(yaml_hash["MIXIN_PIN_CODE"]),
{
asset_id: jsdata["asset_id"],
opponent_id: jsdata["opponent_id"],
amount: jsdata["amount"],
trace_id: SecureRandom.uuid,
memo: "from ruby"
})
p transInfo
end
end如果机器人收到币，
jsdata["amount"]大于零；如果机器人支付币给用户，接收到的消息是一样的，唯一不同的是
jsdata["amount"]是一个负数.
transInfo = MixinBot.api.create_transfer(MixinBot.api.encrypt_pin(yaml_hash["MIXIN_PIN_CODE"]),
{
asset_id: jsdata["asset_id"],
opponent_id: jsdata["opponent_id"],
amount: jsdata["amount"],
trace_id: SecureRandom.uuid,
memo: "from ruby"
})
p transInfo最后一步，调用MixinSDK将币还给用户！
