本文实例讲述了Python实现微信中找回好友、群聊用户撤回的消息功能。分享给大家供大家参考,具体如下:
还在好奇好友撤回了什么消息吗?群里撤回了什么消息?下面的代码实现了:即使群、好友撤回了文本消息、表情、图片等消息,自己也能知道撤回的什么。
#coding=utf-8 import itchat from itchat.content import TEXT from itchat.content import * import sys import time import re import os msg_information = {} face_bug=None #针对表情包的内容 @itchat.msg_register([TEXT,PICTURE,FRIENDS,CARD,MAP,SHARING,RECORDING,ATTACHMENT,VIDEO],isFriendChat=True,isGroupChat=True) def receive_msg(msg): global face_bug msg_time_rec = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime()) #接收消息的时间 if 'ActualNickName' in msg: from_user = msg['ActualUserName'] #群消息的发送者,用户的唯一标识 msg_from = msg['ActualNickName']#发送者群内的昵称 friends = itchat.get_friends(update=True)#获取所有好友 for f in friends: if from_user == f['UserName']: #如果群消息是好友发的 if f['RemarkName']: # 优先使用好友的备注名称,没有则使用昵称 msg_from = f['RemarkName'] else: msg_from = f['NickName'] break groups = itchat.get_chatrooms(update=True)#获取所有的群 for g in groups: if msg['FromUserName'] == g['UserName']:#根据群消息的FromUserName匹配是哪个群 group_name = g['NickName'] group_menbers = g['MemberCount'] break group_name = group_name + "(" + str(group_menbers) +")" else: if itchat.search_friends(userName=msg['FromUserName'])['RemarkName']:#优先使用备注名称 msg_from = itchat.search_friends(userName=msg['FromUserName'])['RemarkName'] else: msg_from = itchat.search_friends(userName=msg['FromUserName'])['NickName'] #在好友列表中查询发送信息的好友昵称 group_name = "" msg_time = msg['CreateTime'] #信息发送的时间 msg_id = msg['MsgId'] #每条信息的id msg_content = None #储存信息的内容 msg_share_url = None #储存分享的链接,比如分享的文章和音乐 if msg['Type'] == 'Text' or msg['Type'] == 'Friends': #如果发送的消息是文本或者好友推荐 msg_content = msg['Text'] #如果发送的消息是附件、视频、图片、语音 elif msg['Type'] == "Attachment" or msg['Type'] == "Video" \ or msg['Type'] == 'Picture' \ or msg['Type'] == 'Recording': msg_content = msg['FileName'] #内容就是他们的文件名 msg['Text'](str(msg_content)) #下载文件 elif msg['Type'] == 'Map': #如果消息为分享的位置信息 x, y, location = re.search( "<location x=\"(.*?)\" y=\"(.*?)\".*label=\"(.*?)\".*", msg['OriContent']).group(1, 2, 3) if location is None: msg_content = r"纬度->" + x.__str__() + " 经度->" + y.__str__() #内容为详细的地址 else: msg_content = r"" + location elif msg['Type'] == 'Sharing': #如果消息为分享的音乐或者文章,详细的内容为文章的标题或者是分享的名字 msg_content = msg['Text'] msg_share_url = msg['Url'] #记录分享的url face_bug = msg_content #将信息存储在字典中,每一个msg_id对应一条信息 time.sleep(2) msg_information.update( { msg_id: { "msg_from": msg_from, "msg_time": msg_time, "msg_time_rec": msg_time_rec, "msg_type": msg["Type"], "msg_content": msg_content, "msg_share_url": msg_share_url, "group_name":group_name } } ) del_info = [] for k in msg_information: m_time = msg_information[k]['msg_time'] #取得消息时间 if int(time.time()) - m_time > 130: #如果消息时间是130秒甚至更久之前的,则删除。 del_info.append(k) if del_info: for i in del_info: msg_information.pop(i) #监听是否有消息撤回 @itchat.msg_register(NOTE,isFriendChat=True,isGroupChat=True,isMpChat=True) def information(msg): #如果这里的msg['Content']中包含消息撤回和id,就执行下面的语句 if '撤回了一条消息' in msg['Content']: old_msg_id = re.search("\<msgid\>(.*?)\<\/msgid\>", msg['Content']).group(1) #在返回的content查找撤回的消息的id old_msg = msg_information.get(old_msg_id) #获取到消息原文,类型:字典 print(old_msg) if len(old_msg_id)<11: #如果发送的是表情包 itchat.send_file(face_bug,toUserName='filehelper') else: #发送撤回的提示给文件助手 msg_body = old_msg['group_name'] + old_msg['msg_from'] +"\n" + old_msg['msg_time_rec'] \ + "撤回了:" + "\n" + r"" + old_msg['msg_content'] #如果是分享的文件被撤回了,那么就将分享的url加在msg_body中发送给文件助手 if old_msg['msg_type'] == "Sharing": msg_body += "\n链接是:" + old_msg.get('msg_share_url') #print(msg_body) itchat.send_msg(msg_body, toUserName='filehelper')#将撤回消息发给文件助手 #有文件的话也要将文件发送回去 if old_msg["msg_type"] == "Picture" \ or old_msg["msg_type"] == "Recording" \ or old_msg["msg_type"] == "Video" \ or old_msg["msg_type"] == "Attachment": file = '@fil@%s' % (old_msg['msg_content']) itchat.send(msg=file, toUserName='filehelper') os.remove(old_msg['msg_content']) msg_information.pop(old_msg_id)# 删除字典旧消息 itchat.auto_login(hotReload=True,enableCmdQR=1) itchat.run()
希望本文所述对大家Python程序设计有所帮助。
