Turn Your WeChat Account into an Auto‑Reply Bot with Itchat and Turing AI

Introduction

Recently I wrote about itchat and now present a simple WeChat auto‑reply robot implemented with about thirty lines of Python code.

Program Overview

The program uses itchat to capture WeChat messages, forwards them to the Turing robot API, receives the reply, and sends it back to the original sender, turning a personal WeChat account into a chatbot.

Installation

pip install itchat

Login

Use itchat.auto_login() to scan a QR code; adding hotReload=True keeps the login state by storing itchat.pkl.

Sending Messages

Use itchat.send('Message Content', 'toUserName') where the second argument is the recipient's UserName, for example sending to the filehelper.

Receiving Messages

Register message handlers with @itchat.msg_register(TEXT) (or other content types). A basic handler can reply with the received text.

@itchat.msg_register(TEXT)
def simple_reply(msg):
    itchat.send_msg('Received: %s' % msg['Text'], toUserName=msg['FromUserName'])
    return "T received: %s" % msg['Text']

Message Types

Picture: itchat.content.PICTURE Recording: itchat.content.RECORDING Card:

itchat.content.CARD

Integrating Turing Bot

Configure the Turing API key and send a POST request to http://www.tuling123.com/openapi/api. The helper function returns the bot's reply.

def get_response(msg):
    apiUrl = 'http://www.tuling123.com/openapi/api'
    data = {'key': KEY, 'info': msg, 'userid': 'wechat-robot'}
    try:
        r = requests.post(apiUrl, data=data).json()
        return r.get('text')
    except:
        return

The message handler uses this function and falls back to a default reply when the API fails.

Full Example

import requests
import itchat

KEY = '8edce3ce905a4c1dbb965e6b35c3834d'

def get_response(msg):
    apiUrl = 'http://www.tuling123.com/openapi/api'
    data = {'key': KEY, 'info': msg, 'userid': 'wechat-robot'}
    try:
        r = requests.post(apiUrl, data=data).json()
        return r.get('text')
    except:
        return

@itchat.msg_register(itchat.content.TEXT)
def tuling_reply(msg):
    defaultReply = 'I received: ' + msg['Text']
    reply = get_response(msg['Text'])
    return reply or defaultReply

itchat.auto_login(hotReload=True)
itchat.run()

Notes

Avoid frequent operations, otherwise Web WeChat may block the login.
