In this article, we share the example of python to achieve the WeChat message anti-withdrawal of the specific code for your reference, the specific content is as follows
Used sqlite3 to save the data and when someone withdraws the message take out the data and send it to the file transfer assistant.
The file will be saved locally first, and the voice will be sent as a file.
wxpy and itchat haven't been updated for a long time, some of the features don't work anymore, and I don't know when webchat will be cool.
Helpful information is in the notes.
