课程简介

创建一个接受消息的机器人

通过本教程，你将学会如何用 Python 创建一个机器人APP,让它能接受消息.

Python 3 安装:

本教程基于Python 3.7.2, 所以你需要安装Python 3.7.2 或以上的版本.

on macOS

brew upgrade
brew install python@3

on Ubuntu, 从第三方的APT源中安装.

sudo apt update
sudo apt install software-properties-common
sudo add-apt-repository ppa:deadsnakes/ppa

当出现下面的提示时，按"回车"继续.

Press [ENTER] to continue or Ctrl-c to cancel adding it.

重新更新一次apt源, 再安装python3.7, python3.7-venv

sudo apt update
sudo apt install python3.7 python3.7-venv
sudo ln -s /usr/bin/python3.7 /usr/bin/python3

检查安装是否成功了，需要检查python3与python3-venv, 正确的提示如下:

$ python3 -V
Python 3.7.2

root@n2:~ python3 -m venv -h
usage: venv [-h] [--system-site-packages] [--symlinks | --copies] [--clear]
            [--upgrade] [--without-pip] [--prompt PROMPT]
            ENV_DIR [ENV_DIR ...]
Creates virtual Python environments in one or more target directories.
positional arguments:
  ENV_DIR               A directory to create the environment in.

optional arguments:
  -h, --help            show this help message and exit
  --system-site-packages
                        Give the virtual environment access to the system
                        site-packages dir.
  --symlinks            Try to use symlinks rather than copies, when symlinks
                        are not the default for the platform.
  --copies              Try to use copies rather than symlinks, even when
                        symlinks are the default for the platform.
  --clear               Delete the contents of the environment directory if it
                        already exists, before environment creation.
  --upgrade             Upgrade the environment directory to use this version
                        of Python, assuming Python has been upgraded in-place.
  --without-pip         Skips installing or upgrading pip in the virtual
                        environment (pip is bootstrapped by default)
  --prompt PROMPT       Provides an alternative prompt prefix for this
                        environment.

Once an environment has been created, you may wish to activate it, e.g. by
sourcing an activate script in its bin directory

创建 mixin_labs-python-bot 项目

你首先需要创建项目目录，初始化"虚拟环境",然后安装需要的软件包.

mkdir mixin_labs-python-bot
cd mixin_labs-python-bot
python3 -m venv ./

在 python3 -m venv 指令完成之后，项目目录如下：

wenewzha:mixin_labs-python-bot wenewzhang$ ls
bin        include        lib        pyvenv.cfg

当"虚拟环境"创建成功后，需要激活它, 通过执行bin目录下相应的activate文件完成.

wenewzha:mixin_labs-python-bot wenewzhang$ source ./bin/activate
(mixin_labs-python-bot) wenewzha:mixin_labs-python-bot wenewzhang$

成功激活后，可以直接执行python或pip了，这时，不再需要输入他们的完整路径了.

在"虚拟环境"里安装必需的包

创建一个必需包的list

requirements.txt

cryptography==2.4.2
pycparser==2.19
pycryptodome==3.7.2
PyJWT==1.7.1
python-dateutil==2.7.5
PyYAML==3.13
requests==2.21.0
websocket-client==0.54.0

通过pip升级pip包本身, 并安装必需包.

pip install --upgrade pip
pip install -r requirements.txt

下载 Mixin Network的python 3的API

wget https://github.com/includeleec/mixin-python3-sdk/raw/master/mixin_ws_api.py
wget https://github.com/includeleec/mixin-python3-sdk/raw/master/mixin_api.py
wget https://github.com/includeleec/mixin-python3-sdk/raw/master/mixin_config.py

你好，世界!

创建第一个机器人APP

按教程，到mixin.one创建一个APP[tutorial].

生成相应的参数

生成必要的参数并且记下来

它们将用于mixin_config.py中.

Python 比特币教程之一：创建机器人

在项目目录下，创建mixin_config.py,将生成的参数，替换成你的！

mixin_config.py

client_id= 'ed882a39-0b0c-4413-bbd9-221cdeee56bf'
client_secret = '8d7ec7b9c8261b6c7bd6309210496ca4b72bce9efc7e49be14a428ce49ff7202'


pay_pin = '599509'

需要替换的参数包括： client_id, client_secret, pay_pin, pin_token, pay_session_id, private key.

创建 app-mini.py 文件, 内容如下:

app-mini.py

from mixin_ws_api import MIXIN_WS_API
from mixin_api import MIXIN_API
import mixin_config

import json
import time
from io import BytesIO
import base64
import gzip

try:
    import thread
except ImportError:
    import _thread as thread


def on_message(ws, message):
    inbuffer = BytesIO(message)

    f = gzip.GzipFile(mode="rb", fileobj=inbuffer)
    rdata_injson = f.read()
    rdata_obj = json.loads(rdata_injson)
    print("-------json object begin---------")
    print(rdata_obj)
    print("-------json object end---------")
    action = rdata_obj["action"]

    if rdata_obj["data"] is not None:
        print("data in message:",rdata_obj["data"])

    if rdata_obj["data"] is not None and rdata_obj["data"]["category"] is not None:
        print(rdata_obj["data"]["category"])

    if action == "CREATE_MESSAGE":

        data = rdata_obj["data"]
        msgid = data["message_id"]
        typeindata = data["type"]
        categoryindata = data["category"]
        userId = data["user_id"]
        conversationId = data["conversation_id"]
        dataindata = data["data"]

        realData = base64.b64decode(dataindata)

        MIXIN_WS_API.replayMessage(ws, msgid)

        if 'error' in rdata_obj:
            return

        if categoryindata == "PLAIN_TEXT":
            realData = realData.decode('utf-8')
            print("dataindata",realData)
            MIXIN_WS_API.sendUserText(ws, conversationId, userId, realData)


if __name__ == "__main__":

    mixin_api = MIXIN_API(mixin_config)

    mixin_ws = MIXIN_WS_API(on_message=on_message)

    mixin_ws.run()

运行 app-mini.py, 记得要先激活“虚拟环境”哦!

(mixin_labs-python-bot) wenewzha:mixin_labs-python-bot wenewzhang$ python app-mini.py
...

如果一切正常，将会有如下提示：

(mixin_labs-python-bot) wenewzha:mixin_labs-python-bot wenewzhang$ python app-mini.py
ws open
-------json object begin---------
{'id': '1c798948-30eb-11e9-a20e-20c9d08850cd', 'action': 'LIST_PENDING_MESSAGES'}
-------json object end---------

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!

Python 比特币教程之一：创建机器人

源代码解释

WebSocket是建立在TCP基础之上的全双工通讯方式，我们需要建立一个loop循环来维持通迅。

if __name__ == "__main__":

    mixin_api = MIXIN_API(mixin_config)
    mixin_ws = MIXIN_WS_API(on_message=on_message)
    mixin_ws.run()

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！

MIXIN_WS_API.replayMessage(ws, msgid)

机器人程序完整回复用户的信息

if categoryindata == "PLAIN_TEXT":
    realData = realData.decode('utf-8')
    print("dataindata",realData)
    MIXIN_WS_API.sendUserText(ws, conversationId, userId, realData)

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 .

完成

现在你的机器人APP运行起来了，开始玩吧。
