在 [上一篇教程中][Link 1], 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！

require 'faye/websocket'
    require 'eventmachine'
    require 'json'
    require 'zlib'
    require 'mixin_bot'
    require 'yaml'
    
    yaml_hash = YAML.load_file('./config.yml')
    
    MixinBot.client_id  = yaml_hash["MIXIN_CLIENT_ID"]
    MixinBot.session_id = yaml_hash["MIXIN_SESSION_ID"]
    MixinBot.client_secret = yaml_hash["MIXIN_CLIENT_SECRET"]
    MixinBot.pin_token   = yaml_hash["MIXIN_PIN_TOKEN"]
    MixinBot.private_key = yaml_hash["MIXIN_PRIVATE_KEY"]
    
    access_token = MixinBot.api.access_token("GET","/","")
    puts access_token
    
    authorization = format('Bearer %s', access_token)
    
    
    
    EM.run {
      ws = Faye::WebSocket::Client.new('wss://blaze.mixin.one/', ["Mixin-Blaze-1"],
        :headers => { 'Authorization' => authorization }
      )
    
      ws.on :open do |event|
        p [:open]
        ws.send(MixinBot.api.list_pending_message)
      end
    
      ws.on :message do |event|
        p [:message]
        data = event.data

### 你好，我的币! ###

在工程目录下，执行 **ruby websocket\_mixin\_bot.rb**

ruby websocket_mixin_bot.rb
    复制代码

wenewzha:mixin_labs-ruby-bot wenewzhang$ ruby websocket_mixin_bot.rb
    [:open]
    [:message]
    {
        "id"=>"1003b2b5-b8e4-4b54-bd03-983c61f64869", "action"=>"LIST_PENDING_MESSAGES"}
    复制代码

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][Mixin Messenger]

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
    复制代码

如果机器人收到币，

jsdata["amount"]
    复制代码

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"]
    复制代码

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
    复制代码

最后一步，调用MixinSDK将币还给用户！
