How to prevent Wechat withdrawal in Python? for this question, this article introduces the corresponding analysis and answer in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

In the process of using Wechat, sometimes the message is withdrawn before it can be seen. After all, everyone has curiosity, knowing that the news has been withdrawn, they would like to see what it is.

I thought to myself that if the goddess confessed her love to me...

Train of thought:

Use the itchat library to cache each received message. Listen for recall events, and when a disappearance is withdrawn, the information is fetched from the cache by msgId and sent to the file transfer assistant. In this way, a simple anti-withdrawal function is implemented.

Python Learning tutorial Operation: cache received messages

Import itchat

From itchat.content import *

Import datetime

Import re

Import os

# Storage path of information accepted by Wechat

FILE_PATH ='/ home/wechat/'

# cached Dictionary for Wechat messages

MSG_DICT = {}

# Wechat message Type Dictionary

MSG_MESSAGE = {'Text':' text', 'Map':' location sharing', 'Sharing':' sharing link'

'Picture':' pictures, 'Video':' videos, 'Card':' business cards'

'Attachment':' attachment', 'Recording':' voice'}

"

Listen for messages

"

# listening messages are TEXT, MAP, SHARING, PICTURE, VIDEO, CARD, RECORDING, ATTACHMENT

Itchat.msg_register ([TEXT, MAP, SHARING, PICTURE, VIDEO, CARD, RECORDING, ATTACHMENT])

Def wechat_msg (msg):

# get message id

Msg_id = msg ['MsgId']

# current time

Msg_time = datetime.datetime.now () .strftime ('% Y-%m-%d% HRV% MRV% S')

# sender

Msg_from = itchat.search_friends (userName=msg ['FromUserName']) [' RemarkName']

# Note: empty to get nickname

If not msg_from:

Msg_from = itchat.search_friends (userName=msg ['FromUserName']) [' NickName']

# content

Msg_text = msg ['Text']

# message type

Msg_type = msg ['Type']

Msg_url = None

# you need to save messages when they are videos, photos, voice messages or attachments

Save_type = [VIDEO, PICTURE, RECORDING, ATTACHMENT]

If msg_type in save_type:

# Save the file

Msg ['Text'] (FILE_PATH + msg [' FileName'])

Msg_text = msg ['FileName']

# message type is map, record url when sharing links

Url_type = [MAP, SHARING]

If msg_type in url_type:

Msg_url = msg ['msg_url']

# Business card

If msg_type = = CARD:

Sex = msg ['RecommendInfo'] [' Sex']

If sex = = 1:

Sex = 'elder brother'

Elif sex = = 2:

Sex = 'Sister'

Else:

Sex = 'ladyBoy'

Msg_text = f 'business card from {msg ["RecommendInfo"] ["Province"]} {msg ["RecommendInfo"] ["City"]} {msg ["RecommendInfo"] ["NickName"]} {sex}.

# messages are put in the dictionary

MSG_ DICT [msg _ id] = {'msg_from': msg_from,' msg_time': msg_time, 'msg_text': msg_text,' msg_url': msg_url, 'msg_type': MSG_ Mesage [msg _ type]}

Print ({'msg_from': msg_from,' msg_time': msg_time, 'msg_text': msg_text,' msg_url': msg_url, 'msg_type': MSG_ MESSAGE [MSG _ type]})

We cache the text, video, voice, image, attachment and other message types received by Wechat into the MSG_DICT dictionary. Next, we can monitor the withdrawal incident.
