一、前言介绍

二、环境准备

三、chatGPT接入

四、源码重写

五、效果展示

趣味模块

近期微软推出了chatGPT，小明想把chatGPT接入到微信群聊中，平日里闲下来没事的时候，和gpt聊聊八卦、谈谈人生、增长一下学习知识。甚至在女朋友不知情的情况下，偷偷看看漂亮小姐姐的图片和视频；而这些功能都希望能通过微信机器人去实现。为了满足小明同学的要求，今天给大家分享一个chatGPT与itchat打造的全网最强机器狗。相信我，一定要看到最后，你肯定不会后悔。

一、前言介绍

1、什么是chatGPT？

ChatGPT是美国人工智能研究实验室OpenAI新推出的一种人工智能技术驱动的自然语言处理工具，使用了Transformer神经网络架构，也是GPT-3.5架构，这是一种用于处理序列数据的模型，拥有语言理解和文本生成能力，尤其是它会通过连接大量的语料库来训练模型，这些语料库包含了真实世界中的对话，使得ChatGPT具备上知天文下知地理，还能根据聊天的上下文进行互动的能力，做到与真正人类几乎无异的聊天场景进行交流。ChatGPT不单是聊天机器人，还能进行撰写邮件、视频脚本、文案、翻译、代码等任务。

2、什么是itchat？

itchat是一个开源的微信个人号接口，使用python调用微信从未如此简单。使用不到三十行的代码，你就可以完成一个能够处理所有信息的微信机器人。当然，该api的使用远不止一个机器人，如今微信已经成为了个人社交的很大一部分。

二、环境准备

为了实现一个微信机器狗，我们需要准备如下的环境和工具包：

• 微信号一个，需要实名认证（itchat会获取登录后的skey，不然无法登录成功）

• chatGPT账号一个，并能够获取Api Key。

• 科学上网工具，不然无法访问chatGPT接口。

• 安装itchat、openai第三方工具包。

• Python环境为Python3；最好是3.7以上版本。

• 有服务器的可以部署到服务器，没有的本地环境也可以。

附上环境安装命令：

pip3 install itchat-uos==1.5.0.dev0pip3 install --upgrade openai

---

三、chatGPT接入

1、查看官方文档，如何使用python接入chatGPT，截图如下：

2、阅读chatGPT官方文档后，编写Python代码如下：

import openai
import requests
# openai api方式
def get_answer_api(keywrod, api_key):
    openai.api_key = api_key
    response = openai.Completion.create(
        model="text-davinci-003",  # 模型
        prompt=keywrod,
        temperature=0.5,
        max_tokens=1024,  # 限制回复字数(一个汉字为两个token)
        top_p=1,
        best_of=1,
        frequency_penalty=0,
        presence_penalty=0,
        # stop=["\n"]
    )
    content = response.get('choices')
    if content:
        text = content[0].get('text').replace('\n', '')
    else:
        text = '对不起，我没有理解你的意思!'
    print(text)
    return text


# requests 请求方式
def get_answer_req(keywrod, api_key):
    url = "https://api.openai.com/v1/completions"
    headers = {'Content-Type': 'application/json', 'Authorization': f'Bearer {api_key}'}
    data = {
        'model': "text-davinci-003",  # 模型
        'prompt': keywrod,
        'temperature': 0.5,
        'max_tokens': 1024,  # 限制回复字数(一个汉字为两个token)
        'top_p': 1,
        'frequency_penalty': 0,
        'presence_penalty': 0,
    }
    response = requests.post(url, headers=headers, json=data)
    content = response.json().get('choices')
    if content:
        text = content[0].get('text').replace('\n', '')
    else:
        text = '对不起，我连接不到你的网络!'
    print(text)
    return text


if __name__ == '__main__':
    api_key = "你的api_key"
    get_answer_api('讲个笑话', api_key)

3、运行代码后，chatGPT输出内容如下图所示：

4、chatGPT接口OK后，我们把它和itchat进行关联，相关代码如下所示：

总结：此刻我们已经把chatGPT和itchat成功结合，实现了微信机器狗自动会话功能，同时也增加了自动发图片、视频功能。但是在小编登录过程中，发现只要登录出现异地操作，二维码会重复弹出的问题，截图如下所示：

为了解决二维码重复弹出问题及程序异常退出问题，我们接下来对itchat官方源码进行重写。

四、源码重写

1、将itchat源码login模块进行重写，重写后代码如下：

import os
import time
import re
import io
import threading
import json
import xml.dom.minidom
import random
import traceback
import logging
try:
    from httplib import BadStatusLine
except ImportError:
    from http.client import BadStatusLine

import requests
from pyqrcode import QRCode

from .. import config, utils
from ..returnvalues import ReturnValue
from ..storage.templates import wrap_user_dict
from .contact import update_local_chatrooms, update_local_friends
from .messages import produce_msg

logger = logging.getLogger('itchat')


def load_login(core):
    core.login = login
    core.get_QRuuid = get_QRuuid
    core.get_QR = get_QR
    core.check_login = check_login
    core.web_init = web_init
    core.show_mobile_login = show_mobile_login
    core.start_receiving = start_receiving
    core.get_msg = get_msg
    core.logout = logout


def login(self, enableCmdQR=False, picDir=None, qrCallback=None,
          loginCallback=None, exitCallback=None):
    if self.alive or self.isLogging:
        logger.warning('itchat has already logged in.')
        return
    self.isLogging = True
    while self.isLogging:
        uuid = push_login(self)
        if uuid:
            qrStorage = io.BytesIO()
        else:
            logger.info('Getting uuid of QR code.')
            while not self.get_QRuuid():
                time.sleep(1)
            logger.info('Downloading QR code.')
            qrStorage = self.get_QR(enableCmdQR=enableCmdQR,
                                    picDir=picDir, qrCallback=qrCallback)
            logger.info('Please scan the QR code to log in.')
        isLoggedIn = False
        while not isLoggedIn:
            status = self.check_login()
            if hasattr(qrCallback, '__call__'):
                qrCallback(uuid=self.uuid, status=status,
                           qrcode=qrStorage.getvalue())
            if status == '200':
                isLoggedIn = True
            elif status == '201':
                if isLoggedIn is not None:
                    logger.info('Please press confirm on your phone.')
                    isLoggedIn = None
                    logger.info('wait 10 seconds.')
                    time.sleep(10)
            elif status != '408':
                break
        if isLoggedIn:
            break
        elif self.isLogging:
            logger.info('Log in time out, reloading QR code.')
    else:
        return  # log in process is stopped by user
    logger.info('Loading the contact, this may take a little while.')
    self.web_init()
    self.show_mobile_login()
    self.get_contact(True)
    if hasattr(loginCallback, '__call__'):
        r = loginCallback()
    else:
        utils.clear_screen()
        if os.path.exists(picDir or config.DEFAULT_QR):
            os.remove(picDir or config.DEFAULT_QR)
        logger.info('Login successfully as %s' % self.storageClass.nickName)
    self.start_receiving(exitCallback)
    self.isLogging = False

总结：在触发状态码为201的时候，进行10秒等待，否则会重复弹出二维码，让你无法登录。

2、将itchat源码core模块进行重写，重写后代码如下：

class Core(object):
    def __init__(self):
        ''' init is the only method defined in core.py
            alive is value showing whether core is running
                - you should call logout method to change it
                - after logout, a core object can login again
            storageClass only uses basic python types
                - so for advanced uses, inherit it yourself
            receivingRetryCount is for receiving loop retry
                - it's 5 now, but actually even 1 is enough
                - failing is failing
        '''
        self.alive, self.isLogging = False, False
        self.storageClass = storage.Storage(self)
        self.memberList = self.storageClass.memberList
        self.mpList = self.storageClass.mpList
        self.chatroomList = self.storageClass.chatroomList
        self.msgList = self.storageClass.msgList
        self.loginInfo = {}
        self.s = requests.Session()
        self.uuid = None
        self.functionDict = {'FriendChat': {}, 'GroupChat': {}, 'MpChat': {}}
        self.useHotReload, self.hotReloadDir = False, 'itchat.pkl'
        self.receivingRetryCount = 1000

    def login(self, enableCmdQR=False, picDir=None, qrCallback=None,
              loginCallback=None, exitCallback=None):
        ''' log in like web wechat does
            for log in
                - a QR code will be downloaded and opened
                - then scanning status is logged, it paused for you confirm
                - finally it logged in and show your nickName
            for options
                - enableCmdQR: show qrcode in command line
                    - integers can be used to fit strange char length
                - picDir: place for storing qrcode
                - qrCallback: method that should accept uuid, status, qrcode
                - loginCallback: callback after successfully logged in
                    - if not set, screen is cleared and qrcode is deleted
                - exitCallback: callback after logged out
                    - it contains calling of logout
            for usage
                ..code::python

                    import itchat
                    itchat.login()

            it is defined in components/login.py
            and of course every single move in login can be called outside
                - you may scan source code to see how
                - and modified according to your own demand
        '''
        raise NotImplementedError()

总结：修改该模块主要因为异常次数过多，itchat微信就会自动退出。重写后将异常次数拉满，这样就能避免因为网络不稳定问题造成微信自动退出。

3、整个项目启动代码配置如下：

{  "open_ai_api_key": "",  "proxy": "127.0.0.1:7890",  "single_chat_prefix": ["机器狗", "@机器狗"],  "single_chat_reply_prefix": "[机器狗] ",  "group_chat_prefix": ["@机器狗", "@机器狗"],  "group_name_white_list": ["机器狗家族", "AI回答"],  "image_create_prefix": ["画", "看", "找"],  "conversation_max_tokens": 1000,  "character_desc": "我是机器狗, 一个由OpenAI训练的大型语言模型, 旨在回答并解决人们的任何问题，并且可以使用多种语言与人交流。",  "expires_in_seconds": 1200}

4、然后将proxy代理部署到linux服务器，部署截图如下：

5、最后将代码运行起来并进行手机扫码登录，登录后log截图如下：

注：此刻我们已经完全脱机，不需要手机保持在线；可以实现24小时*N天超长待机。

五、效果展示

1、代码成功部署服务器后，我们在微信群聊发送指定内容，查看机器狗返回内容如下：

• 机器狗文本信息截图

• 文本图片魔改版截图

• 机器狗图片信息截图

• 机器狗视频信息截图

总结：图片、视频功能是小编通过itchat模块自定义扩展的，并不是chatGPT真实返回的，供大家观赏使用，切勿用于不法用途。

粉丝福利：公众号后台回复 chatgpt 即可获取机器狗完整代码（有效期7天）
