python实现微信群消息自动转发简明教程
基本思路是，用 Python 模拟微信网页版登陆，接收到群里消息后，对文本、图片、分享等各类消息类型分别处理，并转发至其他群。主要源头是使用itchat，itchat是一个开源的微信个人号接口，python实现。
1、准备一个单独的微信号，要一直在线，不能退出。
2、找台电脑，作为服务器，后面要长期运行。
3、服务器上安装python解析器。
4、安装itchat。命令：pip install itchat
5、把代码跑起来。
#coding=utf-8
import sys
import itchat
from itchat.content import *
reload(sys)
sys.setdefaultencoding('utf8')
# @itchat.msg_register(itchat.content.TEXT)
# def text_reply(msg):
# return msg['Text']
# 自动回复文本等类别消息
# isGroupChat=False表示非群聊消息
@itchat.msg_register([TEXT, MAP, CARD, NOTE, SHARING], isGroupChat=False)
def text_reply(msg):
# print "here we are!"
itchat.send('稍后会给您回复!', msg['FromUserName'])
# 自动回复图片等类别消息
# isGroupChat=False表示非群聊消息
@itchat.msg_register([PICTURE, RECORDING, ATTACHMENT, VIDEO], isGroupChat=False)
def download_files(msg):
itchat.send('稍后会给您回复！', msg['FromUserName'])
# 自动处理添加好友申请
@itchat.msg_register(FRIENDS)
def add_friend(msg):
itchat.add_friend(**msg['Text']) # 该操作会自动将新好友的消息录入，不需要重载通讯录
itchat.send_msg(u'您好', msg['RecommendInfo']['UserName'])
# 自动转发文本等类别的群聊消息
# isGroupChat=True表示为群聊消息
@itchat.msg_register([TEXT, SHARING], isGroupChat=True)
def group_reply_text(msg):
# 消息来自于哪个群聊
chatroom_id = msg['FromUserName']
print"消息来自群聊",chatrooms_rename.get(chatroom_id)
# 来自监控组里的群聊信息需要转发到“收信息群”
#来自“收信息群”的群聊信息不需要处理
if not chatroom_id in chatroom_ids:
return
if chatroom_id == list(chatrooms_rename.keys())[list(chatrooms_rename.values()).index("收消息群")]:
print "你在收消息群发送消息"
return
# 发送者的昵称
username = msg['ActualNickName']
print "发送者的昵称",username
# 获取群名
group_name = chatrooms_rename.get(chatroom_id)
if msg['Type'] == TEXT:
content = msg['Content']
elif msg['Type'] == SHARING:
content = msg['Text']
# 根据消息类型转发至其他需要同步消息的群聊
if msg['Type'] == TEXT:
for item in chatrooms:
if not item['UserName'] == chatroom_id:
#写死了，默认需要同步的群只有“收信息群”
itchat.send('%s—%s 说:\n%s' % (group_name, username, msg['Content']), list(chatrooms_rename.keys())[list(chatrooms_rename.values()).index("收消息群")])
elif msg['Type'] == SHARING:
print 5
for item in chatrooms:
if not item['UserName'] == chatroom_id:
itchat.send('%s-%s 分享：\n%s\n%s' % (group_name, username, msg['Text'], msg['Url']), list(chatrooms_rename.keys())[list(chatrooms_rename.values()).index("收消息群")])
# 自动回复图片等类别的群聊消息
# isGroupChat=True表示为群聊消息
@itchat.msg_register([PICTURE, ATTACHMENT, VIDEO], isGroupChat=True)
def group_reply_media(msg):
# 消息来自于哪个群聊
chatroom_id = msg['FromUserName']
# 发送者的昵称
username = msg['ActualNickName']
# 消息并不是来自于需要同步的群
if not chatroom_id in chatroom_ids:
return
# 如果为gif图片则不转发
if msg['FileName'][-4:] == '.gif':
return
# 下载图片等文件
msg['Text'](msg['FileName'])
# 转发至其他需要同步消息的群聊
group_name = chatrooms_rename.get(chatroom_id)
for item in chatrooms:
if not item['UserName'] == chatroom_id:
itchat.send('%s—%s分享：' % (group_name, msg['ActualNickName']),
list(chatrooms_rename.keys())[list(chatrooms_rename.values()).index("收消息群")])
itchat.send('@%s@%s' % ( {'Picture': 'img', 'Video': 'vid'}.get(msg['Type'], 'fil'), msg['FileName']),
list(chatrooms_rename.keys())[list(chatrooms_rename.values()).index("收消息群")])
# 扫二维码登录
# itchat.auto_login(hotReload=False)
itchat.auto_login(hotReload=True)
# 获取所有通讯录中的群聊
# 需要在微信中将需要同步的群聊都保存至通讯录
chatrooms = itchat.get_chatrooms(update=True, contactOnly=True)
print"chatrooms",chatrooms
chatroom_ids = [c['UserName'] for c in chatrooms]
print"chatroom_ids",chatroom_ids
print"正在监测的群聊：", len(chatrooms),"个"
chatrooms_rename = {}
for item in chatrooms:
chatrooms_rename[str(item['UserName'])] = item['NickName']
print"监控群",chatrooms_rename
A=list(chatrooms_rename.keys())[list(chatrooms_rename.values()).index("收消息群")]
itchat.run()
