python-itchat 获取微信群用户信息的实例

如下所示：

import itchat, time
from itchat.content import TEXT
#name = ' '
roomslist = []

itchat.auto_login(enableCmdQR = False)

def getroom_message(n):
 #获取群的username，对群成员进行分析需要用到
 itchat.dump_login_status() # 显示所有的群聊信息，默认是返回保存到通讯录中的群聊
 RoomList = itchat.search_chatrooms(name=n)
 if RoomList is None:
   print("％s group is not found!" ％ (name))
 else:
   return RoomList[0]['UserName']

def getchatrooms():
 #获取群聊列表
 roomslist = itchat.get_chatrooms()
 #print(roomslist)
 return roomslist

for i in getchatrooms():
 #print(i['NickName'])
 roomslist.append(i['NickName'])

with open('群用户名.txt', 'a', encoding='utf-8')as f:
 for n in roomslist:
   ChatRoom = itchat.update_chatroom(getroom_message(n), detailedMember=True)
   for i in ChatRoom['MemberList']:
     #print (i['Province']+":",i['NickName'])
     f.write(i['Province']+":"+i['NickName']+'\n')
     print('正在写入      '+i['Province']+":",i['NickName'])
 f.close()

# for i in ChatRoom:
#   print(i['MemberList']['ContactList'])
#   count += 1
# print(count)

# # @itchat.msg_register(TEXT)
# # def simple_reply(TEXT):
# #   print(msg.text)
# #
# # itchat.auto_login(enableCmdQR = False,hotReload = True) # enableCmdQR=True这一参数为二维码在下面控制台中显示出来，而不是用图片显示
# # itchat.run()
# itchat.auto_login(enableCmdQR = False)
#
# # time.sleep()
# # itchat.logout()
# # friends = itchat.get_friends()
# # for i in friends:
# #   print(i)
# rooms = itchat.get_chatrooms()
# for i in rooms:
#   print(i['NickName'])
#   memberList = itchat.update_chatroom(i['NickName'])
#   print (memberList)
#
# #   room = itchat.update_chatroom(i['NickName'],detailedMember = True)
# #   print(room)
# #   # for i in room:
# #   #   print(i)
