In the previous chapter, your first bot just work. The bot echo message from user. The bot can receive Bitcoin and send Bitcoin back to user after we write some code.
Create an websocket_mixin_bot.rb file with following code:
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)

}Run ruby websocket_mixin_bot.rb in the project directory.
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"}The bot connect to the mixin.one successfully when console output "LIST_PENDING_MESSAGES".
The bot has told you how to interact:
- 1 the bot send an APP_CARD link.
- 2 the bot send an APP_BUTTON_GROUP link.
- ? or help for help!
Click the links in chatting page, input PIN code to pay coin to bot.
Full Mixin Messenger messages introduction.
User can pay 0.001 Bitcoin to bot, the 0.001 Bitcoin will be refunded in 1 seconds. In fact, user can pay any coins.
Developer can send Bitcoin to their bots in chatting page. The bot will send back immediately after received Bitcoin.
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"]),

opponent_id: jsdata["opponent_id"],
amount: jsdata["amount"],
trace_id: SecureRandom.uuid,
memo: "from ruby"
})
p transInfo
end
end- The jsdata["amount"] is negative if bot sends Bitcoin to user successfully.
- The jsdata["amount"] is positive if bot receives Bitcoin.
Following code transfer the Bitcoin to user.
transInfo = MixinBot.api.create_transfer(MixinBot.api.encrypt_pin(yaml_hash["MIXIN_PIN_CODE"]),
{
asset_id: jsdata["asset_id"],
opponent_id: jsdata["opponent_id"],
