Build a Custom WeChat Group Chat Bot in 30 Lines of Python

Preparation

Python development environment – macOS includes Python by default; Windows users should download Python from the official website and verify the version with python .

Install the itchat library via pip install itchat .

Obtain a free Turing Robot API key by registering on the Turing Robot website.

Implementation of the WeChat Chat Assistant

The following script uses itchat to receive messages and the Turing API to generate replies. It works for both private chats and group chats.

import itchat
import requests
def get_response(msg):
    apiUrl = 'http://www.tuling123.com/openapi/api'
    data = {
        'key': '8edce3ce905a4c1dbb965e6b35c3834d',  # Turing Key
        'info': msg,  # message content
        'userid': 'wechat-robot',
    }
    r = requests.post(apiUrl, data=data).json()
    return r.get('text')
@itchat.msg_register(itchat.content.TEXT)
def print_content(msg):
    return get_response(msg['Text'])
@itchat.msg_register([itchat.content.TEXT], isGroupChat=True)
def print_content(msg):
    return get_response(msg['Text'])
itchat.auto_login(True)
itchat.run()

Explanation

The script relies on two libraries: itchat for WeChat interaction and requests for HTTP calls to the Turing API.

@itchat.msg_register(itchat.content.TEXT) handles messages from individual contacts.

@itchat.msg_register([itchat.content.TEXT], isGroupChat=True) handles messages from group chats.

When a message is received, get_response() sends it to the Turing API and returns the reply, which is then sent back to WeChat.

itchat.auto_login(True) displays a QR code for login; after scanning, the bot operates automatically.

Conclusion

The lightweight Python bot demonstrates how a few lines of code can automate WeChat group interactions, and the approach can be extended for various use cases such as product recommendation, moderation, or custom notifications.
