大家好，这里是程序员晚枫，正在all in AI编程实战。

第25讲：AI微信机器人——让AI帮你聊微信

AI微信机器人能做什么？

自动回复好友消息
智能客服
定时群发消息
自动拉群

1、安装微信库

1	pip install python-office itchat-unofficial

2、自动回复好友

import itchat
from openai import OpenAI

client = OpenAI(api_key="你的Key", base_url="https://api.deepseek.com")

@itchat.msg_register(itchat.content.TEXT)
def reply(msg):
    """收到消息时自动回复"""
    user_message = msg["Text"]
    
    # 过滤群消息，只处理好友
    if msg["FromUserName"].startswith("@"):
        # AI生成回复
        response = client.chat.completions.create(
            model="deepseek-chat",
            messages=[{
                "role": "user",
                "content": f"你是一个热情的客服，回复用户问题：\n{user_message}"
            }]
        )
        reply_text = response.choices[0].message.content
        
        # 发送回复
        itchat.send(reply_text, msg["FromUserName"])
        print(f"已回复：{reply_text}")

# 登录微信
itchat.auto_login(hotReload=True)
itchat.run()

3、关键词自动回复

import itchat

keyword_responses = {
    "价格": "我们产品的价格是XXX，详情请联系客服。",
    "地址": "我们的地址是：重庆市渝北区XXX",
    "营业时间": "我们的营业时间是：周一到周五 9:00-18:00",
}

@itchat.msg_register(itchat.content.TEXT)
def keyword_reply(msg):
    for keyword, response in keyword_responses.items():
        if keyword in msg["Text"]:
            itchat.send(response, msg["FromUserName"])
            return

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

4、定时群发消息

import itchat
import schedule
import time

def send_broadcast():
    """向所有好友发送消息"""
    friends = itchat.get_friends()
    
    response = client.chat.completions.create(
        model="deepseek-chat",
        messages=[{
            "role": "user",
            "content": "生成一条温馨的早安问候语，不超过50字"
        }]
    )
    message = response.choices[0].message.content
    
    for friend in friends[:50]:  # 避免被封，每次发50人
        try:
            itchat.send(message, friend["UserName"])
            print(f"已发送给：{friend['NickName']}")
        except:
            pass
        time.sleep(2)  # 避免频率过高

# 每天早上8点群发
schedule.every().day.at("08:00").do(send_broadcast)

itchat.auto_login(hotReload=True)

while True:
    schedule.run_pending()
    time.sleep(60)

5、AI客服机器人

@itchat.msg_register(itchat.content.TEXT)
def ai客服(msg):
    """AI智能客服"""
    user_message = msg["Text"]
    
    # 构建上下文
    system_prompt = """你是程序员晚枫的AI助手"小枫"。
性格：热情、专业、幽默
擅长：Python编程、AI使用、技术问题解答
回复风格：简洁有趣，带emoji"""

    response = client.chat.completions.create(
        model="deepseek-chat",
        messages=[
            {"role": "system", "content": system_prompt},
            {"role": "user", "content": user_message}
        ]
    )
    
    reply_text = response.choices[0].message.content
    itchat.send(reply_text, msg["FromUserName"])

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