一、pip Install itchat
Now that python is used to solve the problem, the first step is of course to clarify what library to use, and directly execute pip install itchat:
done!
Two, itchat.login ()
After downloading the library, you have to try the most basic usage of the library, la la la:
But I didn't expect that when the reproduction reached this step, there would be a problem. Directly use the itchat library to operate like the above, and the login will be the web version of WeChat. In order to prevent people from using computers to automatically operate WeChat, which may cause some security problems, Tencent has blocked the web version of WeChat API. If it is just like the above If you do, the console will remind you that "Due to security reasons, this WeChat account cannot use the web version of WeChat. You can use +Windows+ version of WeChat or +Mac+ version of WeChat to log in."
ok, men have to be patient and calm when things happen, google+ Zhihu, if you haven't tried seven or forty-nine solutions, you must not directly consider smashing the computer.
Well, after some trial and error, I found a simple and convenient solution:
Very good, the above operations are completed, and the login is successful!
三、itchat.search_friends() + send()
Very good, the login is successful, let's try to send a message to a friend?
I roughly executed code like this:
Results of the:
Very good, sent successfully!
4. @itchat.msg_register()
Next, we want to listen to the messages sent by our friends, and try to execute this code in the reference document locally:
The effect reproduced on my local machine, there is nothing wrong with it, the effect is great, I can monitor everything on the console, hehehe:
五、def reserver_info(msg)
Next, let's reproduce the following paragraph:
The situation on my machine
六、@itchat.msg_register([TEXT, PICTURE, RECORDING])
The monitoring of the text content has been completed above, and the next step is to experience how to deal with pictures and voices.
Try to reproduce the following code:
This machine reproduced successfully, but I will not let it go, otherwise I have to code again, which is very troublesome [cover face] The explanation of the image format and audio format in the original text:
七、os.mkdir() + info()
We are now involved in how to store pictures and voice information.
And what I will continue to do next, the statement of low EQ is: continue to copy; the statement of high EQ: the reusability of other people's code is very high.
Reproduce this code locally:
Results of the:
Is it that python is so easy to execute smoothly, making people feel boring and tedious? Hhh, if labor and management wanted to use other people's C++ code back then, they didn't have the spirit of learning from the past, and it would be impossible to adjust to such a difficult life.
Eight, note_info (msg)
Now we can store chat messages, that is, since we are making anti-withdrawal software, we should only need to store those withdrawn messages, so how can we judge which messages are withdrawn messages? The Content module provides us with the NOTE type, which refers to system messages:
Ok, let's continue to reproduce the above program locally:
Successful reproduction is boring.
Nine, the complete program code
Finally, the code of the complete program:
import itchat
from itchat.content import *
import os
import time
import xml.dom.minidom # 解析xml模块
# 这是保存撤回消息的文件目录(如：图片、语音等)，这里已经写死了，大家可以自行修改

if not os.path.exists(temp):
os.mkdir(temp)

itchat.run()
operation result:
