Ruby 比特币开发教程: 机器人接受比特币并立即退还用户
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!
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 msg = MixinBot.api.read_message(data) jsmsg = JSON.parse msg p jsmsg # p jsmsg["data"] if jsmsg["action"] == "CREATE_MESSAGE" && jsmsg["data"] != nil msgid = jsmsg["data"]["message_id"] ws.send(MixinBot.api.acknowledge_message_receipt(msgid)) if jsmsg["data"]["category"] == "PLAIN_TEXT" conversation_id = jsmsg["data"]["conversation_id"] decoded_msg = Base64.decode64 jsmsg["data"]["data"] p decoded_msg if decoded_msg == "?" or decoded_msg == "h" or decoded_msg == "H" reply_msg = "?: help\n" + "1: Payment link for APP_CARD\n" + "2: Payment link for APP_BUTTON_GROUP\n" reply_msg = MixinBot.api.plain_text_message(conversation_id,reply_msg) ws.send(reply_msg) elsif (decoded_msg == "1") payLinkEOS = "https://mixin.one/pay?recipient=" + "a1ce2967-a534-417d-bf12-c86571e4eefa" + "&asset=" + "6cfe566e-4aad-470b-8c9a-2fd35b49c68d" + "&amount=0.001" + "&trace=" + SecureRandom.uuid + "&memo=" msgData = { 'icon_url':"https://mixin.one/assets/98b586edb270556d1972112bd7985e9e.png", 'title':"Pay 0.001 EOS", 'description':"pay", 'action':payLinkEOS } ws.send(MixinBot.api. app_card_message(conversation_id, msgData)) elsif decoded_msg == "2" payLinkEOS = "https://mixin.one/pay?recipient=" + "a1ce2967-a534-417d-bf12-c86571e4eefa" + "&asset=" + "6cfe566e-4aad-470b-8c9a-2fd35b49c68d" + "&amount=0.001" + "&trace=" + SecureRandom.uuid + "&memo=" payLinkEOS = "https://mixin.one/pay?recipient=" + MixinBot.client_id + "&asset=" + "6cfe566e-4aad-470b-8c9a-2fd35b49c68d" + "&amount=0.001" + "&trace=" + SecureRandom.uuid + "&memo=" payLinkBTC = "https://mixin.one/pay?recipient=" + MixinBot.client_id + "&asset=" + "c6d0c728-2624-429b-8e0d-d9d19b6592fa" + "&amount=0.0001" + "&trace=" + SecureRandom.uuid + "&memo=" button1 = { label: "Pay 0.001 EOS", color: "#FFABAB", action: payLinkEOS } button2 = { label: "Pay 0.0001 BTC", color: "#00EEFF", action: payLinkBTC } buttons = [button1,button2] ws.send(MixinBot.api. app_button_group_message(conversation_id, jsmsg["data"]["user_id"], buttons)) p "send app button group" else reply_msg = MixinBot.api.plain_text_message(conversation_id,decoded_msg) ws.send(reply_msg) end end 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 end end ws.on :error do |event| p [:error] end ws.on :close do |event| p [:close, event.code, event.reason] ws = nil end }
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!
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!
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!
