就像黑火药时代里突然诞生的核弹一样，OpenAI的ChatGPT语言模型的横空出世，是人工智能技术发展史上的一个重要里程碑。这是一款无与伦比、超凡绝伦的模型，能够进行自然语言推理和对话，并且具有出色的语言生成能力。

好吧，本篇的开头其实是由ChatGPT生成的：

没办法，面对这个远超时代的AI产品，我们能说什么呢？顶礼膜拜？惊为天人？任何言语对于描述ChatGPT来说已经是苍白无力的，而辞海中的形容词在面对ChatGPT时也已经鞭长莫及。

一句话：言语不能赞其伟大。

本次我们利用ChatGPT的开放API接入钉钉群聊/单聊机器人，让钉钉机器人具备进行自然语言推理和对话的能力，所谓化腐朽为神奇，不过如此。

注册和使用OpenAi的ChatGPT

首先注册OpenAi平台：https://beta.openai.com/ ，由于ChatGPT过于火爆，导致很多地区无法正常注册，这里推荐使用北美地区的代理IP，与此同时，一定要注意，如果之后希望使用后端的API接口方式调用ChatGPT，就不要使用谷歌或者微软的三方账号进行登录，否则无法通过邮箱和秘钥交换OpenAi平台的access_token，切记。

同时，接受验证码手机号也必须是北美地区的手机号，这里推荐一个北美地区的接码平台：https://sms.qisms.com/index 非常好用。

注册成功之后，这里推荐github上开源大神rawandahmad698已经封装好的开源SDK，避免重复造轮子：https://github.com/rawandahmad698/PyChatGPT

安装SDK:

pip3 install chatgptpy --upgrade

安装好之后，编写测试脚本：

chat = Chat(email="OpenAi邮箱", password="OpenAi密码",proxies="代理地址")  
  
answer = chat.ask("你好")  
  
print(answer)

注意，运行代码之前，一定要使用代理proxies，并且确保是北美地区的IP地址。

程序返回：

首次运行程序会通过代理自动登录OpenAi平台，并且换取token，最后将token存储在本地。

随后返回ChatGPT的信息：

➜  mydemo git:(master) ✗ /opt/homebrew/bin/python3.10 "/Users/liuyue/wodfan/work/mydemo/test_chatgpt.py"  
Using proxies: http://localhost:4780  
你好，很高兴为你提供帮助。有什么需要我帮忙的吗？

至此，ChatGPT接口就调试好了。

配置钉钉Dingding机器人

随后，我们来配置C端的机器人，注意这里一定要使用支持outgoing回调的企业机器人，而不是普通的机器人，参考文档：https://open.dingtalk.com/document/group/enterprise-created-chatbot

创建好企业机器人之后，获取机器人应用的Key和秘钥，同时配置好出口IP和接口地址：

所谓出口IP即调用钉钉服务合法的ip，消息接受地址是接受C端信息的地址，这里我们使用异步非阻塞的Tornado框架来构建接受信息服务：

import hmac  
import hashlib  
import base64  
import json  
import tornado  
  
from tornado.options import define, options  
define('port', default=8000, help='default port',type=int)  
  
class Robot(tornado.web.RequestHandler):  
  
    async def post(self):  
  
  
        timestamp = self.request.headers.get('timestamp', None)  
  
        sign = self.request.headers.get('sign', None)  
        app_secret = '钉钉机器人秘钥'  
        app_secret_enc = app_secret.encode('utf-8')  
        string_to_sign = '{}\n{}'.format(timestamp, app_secret)  
        string_to_sign_enc = string_to_sign.encode('utf-8')  
        hmac_code = hmac.new(app_secret_enc, string_to_sign_enc, digestmod=hashlib.sha256).digest()  
        my_sign = base64.b64encode(hmac_code).decode('utf-8')  
        if sign != my_sign:  
            return self.finish({"errcode":1,"msg":"签名有误"})  
        data = json.loads(self.request.body)  
        text = data['text']["content"]  
        atUsers = data.get("atUsers",None)  
        uid = data.get("senderStaffId",None)  
        return self.finish({"errcode":0,"msg":text})  
  
urlpatterns = [  
    (r"/robot_chat/",Robot),  
]  
  
  
# 创建Tornado实例  
application = tornado.web.Application(urlpatterns,debug=True)  
  
  
if __name__ == "__main__":  
    tornado.options.parse_command_line()  
    application.listen(options.port)  
    tornado.ioloop.IOLoop.instance().start()

这里我们通过Robot异步控制器来接受所有来自钉钉客户端的信息，即人类对机器人说的话，需要注意的是，后端服务需要对请求头中的timestamp和sign进行验证，以判断是否是来自钉钉的合法请求，避免其他仿冒钉钉调用开发者的HTTPS服务传送数据。

所以这里一旦签名有问题，就结束逻辑：

timestamp = self.request.headers.get('timestamp', None)  
  
sign = self.request.headers.get('sign', None)  
app_secret = '钉钉机器人秘钥'  
app_secret_enc = app_secret.encode('utf-8')  
string_to_sign = '{}\n{}'.format(timestamp, app_secret)  
string_to_sign_enc = string_to_sign.encode('utf-8')  
hmac_code = hmac.new(app_secret_enc, string_to_sign_enc, digestmod=hashlib.sha256).digest()  
my_sign = base64.b64encode(hmac_code).decode('utf-8')  
if sign != my_sign:  
    return self.finish({"errcode":1,"msg":"签名有误"})

最后该接口会返回发信人id（uid）以及具体信息内容（text）。

至此，后端接受服务就配置好了。

下面就是后端推送服务，首先，根据官方文档：https://open.dingtalk.com/document/orgapp-server/obtain-the-access_token-of-an-internal-app?spm=ding_open_doc.document.0.0.5f255239xgW3zE#topic-2056397

需要获取钉钉接口的token:

def get_token(self):  
  
        res = requests.post("https://api.dingtalk.com/v1.0/oauth2/accessToken",data=json.dumps({"appKey":self._appKey,"appSecret":self._appSecret}),headers={"Content-Type":"application/json"})  
  
        token = res.json()["accessToken"]  
  
        return token

随后，根据文档：https://open.dingtalk.com/document/group/chatbots-send-one-on-one-chat-messages-in-batches?spm=ding_open_doc.document.0.0.22e749acXECz5m#topic-2080109

我们来配置单聊推送：

# 单聊  
    def send_message(self,uid,message):  
  
        res = requests.post("https://api.dingtalk.com/v1.0/robot/oToMessages/batchSend",data=json.dumps({"robotCode":self._appKey,"userIds":[uid],"msgKey":"sampleText","msgParam":'{"content":"'+message+'"}'}),headers={"Content-Type":"application/json","x-acs-dingtalk-access-token":self._token})  
  
        print(res.text)

具体效果：

接着，继续根据官方文档：https://open.dingtalk.com/document/robots/guide-to-user-access-for-intra-enterprise-robot-group-chat

配置群聊推送方法：

# 群聊  
    def send_user(self,uid,message):  
  
        data = {  
        "at": {  
            "atUserIds": [  
                uid  
            ]  
        },  
        "text": {  
            "content": message  
        },  
        "msgtype": "text"  
        }  
  
        res = requests.post(self._webhook,data=json.dumps(data),headers={"Content-Type":"application/json"})  
  
        print(res.text)

群聊效果：

这里需要注意的是，单聊是通过接口的方式进行推送，而群内聊天是通过webhook方式进行推送，关于webhook，请移玉步至：使用python3.7配置开发钉钉群自定义机器人(2020年新版攻略)

完整代码：

import requests  
import json  
  
from pychatgpt import Chat  
  
class DingDing:  
  
  
    def __init__(self,appKey=None,appSecret=None) -> None:  
  
        self._appKey = appKey  
  
        self._appSecret = appSecret  
          
        self._token = self.get_token()  
  
        # 机器人webhook地址  
        self._webhook = ""  
  
          
  
  
    def get_token(self):  
  
        res = requests.post("https://api.dingtalk.com/v1.0/oauth2/accessToken",data=json.dumps({"appKey":self._appKey,"appSecret":self._appSecret}),headers={"Content-Type":"application/json"})  
  
        token = res.json()["accessToken"]  
  
        return token  
  
    # 单聊  
    def send_message(self,uid,message):  
  
        res = requests.post("https://api.dingtalk.com/v1.0/robot/oToMessages/batchSend",data=json.dumps({"robotCode":self._appKey,"userIds":[uid],"msgKey":"sampleText","msgParam":'{"content":"'+message+'"}'}),headers={"Content-Type":"application/json","x-acs-dingtalk-access-token":self._token})  
  
        print(res.text)  
  
    # 群聊  
    def send_user(self,uid,message):  
  
        data = {  
        "at": {  
            "atUserIds": [  
                uid  
            ]  
        },  
        "text": {  
            "content": message  
        },  
        "msgtype": "text"  
        }  
  
        res = requests.post(self._webhook,data=json.dumps(data),headers={"Content-Type":"application/json"})  
  
        print(res.text)  
  
  
  
  
if __name__ == '__main__':  
  
    dingding = DingDing("appkey","appSecret")  
  
    #chat = Chat(email="OpenAi邮箱", password="OpenAi密码",proxies="代理地址")  
  
    #answer = chat.ask("你好")  
  
    # 单聊  
    #dingding.send_message('uid',answer)  
  
    # 群聊  
    #dingding.send_user('uid',answer)  
  
    #print(answer)

至此，后端推送服务就配置好了。

结语

最后，奉上Github项目地址，与众亲同飨：https://github.com/zcxey2911/Python_ChatGPT_ForDingding_OpenAi ，毫无疑问，ChatGPT是NLP领域历史上最伟大的项目，没有之一，伟大，就是技术层面的极致，你同意吗？
