tx在8月初将酷q等一切工具搞掉了, 但是我的砖还得搬, 于是临时写了一个抓取消息的脚本。
原理是通过IAccessible接口抓取聊天窗口的消息再处理得到每条消息, 不才, 现成资料是用ahk调用dll然后我就直接用了而没有折腾改成Python。
使用方法:
三个文件放一起,
os.system("start QQ抓取.ahk xxx")   xxx改成要监控的窗口名, 多个窗口就复制这行
destination = ('127.0.0.1', 5888)      用socket把消息发到这个地址
import os
import threading
import socket
import json
import re


def parser(new_text, l_old_text):
    new_text = re.sub(r"\n {2}(?=.+\(\d+\) ( |202\d-\d\d-\d\d )\d\d:\d\d:\d\d)", '-cut-', new_text.replace('\r', '\n'))  # \r改\n, 在每个用户标识前将'\n  '替换成分隔符号-cut-(不直接split是因为空格开头的消息会出错)
    l_new_text = new_text.split('-cut-')
    for text in l_new_text:
        if text not in l_old_text:
            QQID = re.search(r"(?<=\()\d+(?=\))", text).group()
            message = re.search(r"(?<=\d\d:\d\d:\d\d\n ).+", text, re.DOTALL).group()
            client = socket.socket()
            try:
                client.connect(destination)
                client.send(json.dumps({'type': 'message', 'user_id': QQID, 'message': message}).encode('utf8'))
            except Exception:
                print("异常 - 发送失败")
            client.close()
    return l_new_text


def handle_receive(client):
    receive = client.recv(65536).decode('utf8')
    if "ahk-" in receive:
        name = receive
        l_old_text = []
        print('已连接:', receive)
        while True:
            try:
                all_text = client.recv(65536).decode('utf8')
                if all_text:
                    l_old_text = parser(all_text[2:-2], l_old_text)  # 不要前面空格和最后面\r空格
                else:
                    client.close()
                    print('\n已断开:', name)
                    break
            except Exception as e:
                print('异常 - 处理消息', name, e)

如果做成一个实时转发群消息的功能就更好了。比如从A群转到B群
