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!

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.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)

你好,我的币!

在工程目录下,执行 ruby websocket_mixin_bot.rb

ruby websocket_mixin_bot.rb
wenewzha: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!

pay-links

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!
click-pay-link-to-pay

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!
pay-link

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!
transfer and tokens

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!
