Python 发送微信消息

安装

pip install itchat

1、基本使用

# 使用微信接口给微信好友发送消息，
import itchat

nickname = "迪丽热巴"
send_message = "测试消息"
try:
    # 1. 自动登录方法, hotReload=True可以缓存, 不用每次都登录, 但是第一次执行时会出现一个二维码, 需要手机微信扫码登录
    itchat.auto_login(hotReload=False)
    # 2. 搜索好友，search_friends("xxx"),其中"xxx"为好友昵称，备注或微信号不行
    userinfo = itchat.search_friends(nickname)
    # 3. 获取用户id
    userid = userinfo[0]["UserName"]
    # 4. 调用微信接口发送消息
    # 4.1 通过用户id发送信息
    itchat.send(send_message, userid)
    # 4.2 发送纯文本信息
    itchat.send_msg(msg=send_message, toUserName=userid)
except Exception as e:
    print("消息发送异常：", e)
finally:
    # 退出微信
    itchat.logout()

2、批量发送

import itchat

class SendWeChat():
    def __init__(self):
        # 自动登录
        itchat.auto_login(hotReload=False)
        self.UserNameList = []

    def get_user_name(self, nickname_list):
        for nickname in nickname_list:
            try:
                # 根据用户昵称搜索用户
                userinfo = itchat.search_friends(nickname)
                # 获取用户id 并添加至列表
                self.UserNameList.append(userinfo[0]["UserName"])
            except Exception:
                print(f"抱歉无法找到昵称 {nickname} 为用户")

    def send_message(self, message):
        for UserName in self.UserNameList:
            res = itchat.send(message, UserName)
            if res["BaseResponse"]["Ret"] != 0:
                print("消息发送失败: ", UserName)
            else:
                print("消息发送成功: ", UserName)

if __name__ == '__main__':
    nickname_list = ['迪丽热巴', '景田']
    message = "有些性情，崇高不可遏，高傲不可屈。"
    send_wechat = SendWeChat()
    send_wechat.get_user_name(nickname_list)
    send_wechat.send_message(message)

3、异步发送消息

import asyncio
import itchat

class SendWeChat():
    def __init__(self):
        # 自动登录
        itchat.auto_login(hotReload=False)
        self.UserNameList = []

    async def get_user_name(self, nickname_list):
        for nickname in nickname_list:
            try:
                # 根据用户昵称搜索用户
                userinfo = itchat.search_friends(nickname)
                # 获取用户id 并添加至列表
                self.UserNameList.append(userinfo[0]["UserName"])
            except Exception:
                print(f"抱歉无法找到昵称 {nickname} 为用户")

    async def send_message(self, message):
        for UserName in self.UserNameList:
            res = itchat.send(message, UserName)
            if res["BaseResponse"]["Ret"] != 0:
                print("消息发送失败: ", UserName)
            else:
                print("消息发送成功: ", UserName)

    async def main(self, nickname_list, message_list):
        # 异步获取用户列表 并等待完成
        await self.get_user_name(nickname_list)
        tasks = [asyncio.create_task(self.send_message(message)) for message in message_list]
        # 等待结束
        await asyncio.wait(tasks)

if __name__ == '__main__':
    nickname_list = ['迪丽热巴', '景田']
    message_list = ["有些性情，崇高不可遏，高傲不可屈。", "There are some natures too noble to curb and too lofty to bend."]
    send_wechat = SendWeChat()
    asyncio.run(send_wechat.main(nickname_list, message_list))
