1. 创建一个机器人

创建一个接受消息的机器人

通过本教程，你将学会如何用Ruby创建一个机器人APP,让它能接受消息.

Ruby 环境安装:

本教程的程序基于 Ruby 开发.

On macOS

brew update
brew install rbenv
rbenv install 2.6.3
rbenv shell 2.6.3

On Ubuntu

sudo apt update
sudo apt install git curl libssl-dev libreadline-dev zlib1g-dev autoconf  \
bison build-essential libyaml-dev libreadline-dev libncurses5-dev libffi-dev libgdbm-dev

curl -sL https://github.com/rbenv/rbenv-installer/raw/master/bin/rbenv-installer | bash -

echo 'export PATH=/root/.rbenv/bin:$PATH' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
source ~/.bashrc

rbenv install 2.6.3
rbenv shell 2.6.3

检查安装情况！

wenewzha:~ wenewzhang$ rbenv shell 2.6.3
wenewzha:minecraft wenewzhang$ ruby -v
ruby 2.6.3p62 (2019-04-16 revision 67580) [x86_64-darwin18]

安装依赖包

本教程依赖 faye-websocket 与 mixin_bot.

gem install faye-websocket
gem install mixin_bot

创建你的项目

到你的工作文档中，创建一个目录，并取一个名字，比如:mixin_labs-ruby-bot

mkdir mixin_labs-ruby-bot
mixin_labs-ruby-bot

创建第一个机器人APP

按下面的提示，到mixin.one创建一个APPtutorial.

生成相应的参数

记下这些生成的参数
它们将用于config.yml中.

在项目目录下，创建config.yml,将生成的参数，替换成你的！

config.yml

`> config.yml

需要替换的参数包括： client_id, client_secret, and the pin, pin token, session_id, private key.

经典的Hello world

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
        reply_msg = MixinBot.api.plain_text_message(conversation_id, decoded_msg)
        ws.send(reply_msg)
      end
      if jsmsg["data"]["category"] == "SYSTEM_ACCOUNT_SNAPSHOT"
        jsdata =  JSON.parse (Base64.decode64(jsmsg["data"]["data"]))
        p jsdata
      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
}

编译与运行

执行 ruby websocket_mixin_bot.rb 程序

ruby websocket_mixin_bot.rb

如果一切正常，显示如下：

[:open]
[:message]
{"id"=>"2e13092f-4048-488f-82bc-f5ee9f984002", "action"=>"LIST_PENDING_MESSAGES"}

在手机安装 Mixin Messenger,增加机器人为好友,(比如这个机器人是7000101639) 然后发送消息给它,效果如下!

Mixin Messenger支持的消息类型很多，具体可到下面链接查看: WebSocket消息类型.

源代码解释

每接收到一个消息，需要按消息编号(message_id)给服务器回复一个”已读”的消息,避免服务器在机器人重新登入后，再次发送处理过的消息！

ws.send(MixinBot.api.acknowledge_message_receipt(msgid))

完成

现在你的机器人APP运行起来了，你打算如何改造你的机器人呢？
