Python 3.7'nin ayrıştırma işlemini bir kez kaydedin
Python 3.7 tarafından derlenmiş bir exe bulundu, ancak kaynak kodunu bulamadı. Ayrıştırma işlemini kaydedin
1. Exe dosyasını pyc dosyasına dönüştürün
pyinstxtrator.py kullanarak komutu cmd'ye girin:
python pyinstxtractor . p xxx . exe
Proje adresi: pyinstxtractor
After successful decompression, a [XXX. Exe] extracted folder will appear in the same path, which contains the main program without any suffix. What we need to decompile is this file, and others are dependent libraries, such as pyz extracted folder. At this point, we may wonder why this file is not a. pyc file? This may be one of the shortcomings of the pyinstxtrator. The main program converted is not in the right format. We need to fix it manually.
2. Repair pyc file
If you directly change the suffix of the main file to main.pyc for decompilation, an error will occur.

The reason is that the file header magic number is not aligned, so you need to add magic number. Different python versions of magic number are different.
python 3.6.7's
33 0D 0D 0A 00 00 00 00 00 00 00 00
python 3.7.4's
42 0D 0D 0A 00 00 00 00 63 AF 36 3E 0C 00 00 00
3. How to get magic number
Compile one by yourself to see how many
pyinstaller is required for compiling py files, and modules can be installed with pip
pip install pyinstaller
After pip installation, you can choose a py file to compile. The pyinstaller file location is:
C:\Users\xxx\AppData\Local\Programs\Python\Python36\Scripts\
Drag pyinstaller.exe and one of your py files to the same folder
Input in cmd:
pyinstaller 1.py

Generate the files in the diagram. The pyc file is in pycache
Hexadecimal view its magic number
This is python 3.7.4
4. Add magic number
Add magic number at the top
Customary
After adding
Save as pyc file
5. Decompile pyc files
Decompilation with uncompyle6 is also pip
pip install uncompyle6
Same as open input in cmd
uncompyle6 main.pyc > main.py
Generate main.py directly
I decompiled the file, python 3.7's
# uncompyle6 version 3.6.3 # Python bytecode 3.7 (3394) # Decompiled from: Python 3.7.4 (tags/v3.7.4:e09359112e, Jul 8 2019, 20:34:20) [MSC v.1916 64 bit (AMD64)] # Embedded file name: main.py # Size of source mod 2**32: 12 bytes import os, time from datetime import datetime, timedelta from selenium import webdriver from selenium.webdriver.support.wait import WebDriverWait import selenium.webdriver.support as EC from selenium.webdriver.common.by import By from selenium.webdriver.common.action_chains import ActionChains from packaging import version import requests class Taobao: __module__ = __name__ __qualname__ = 'Taobao' def __init__(self, driver_type): self._browser_type = driver_type if driver_type == 1: self._driver = webdriver.Chrome(executable_path='chromedriver.exe', service_args=['--verbose', '--log-path=chromedriver.log']) else: self._driver = webdriver.Firefox(executable_path='geckodriver.exe') . . . . . There's no sticking in the back
ps: the original python 3.6.6 of my computer needs to be decompiled and written in 3.7, so I can add a 3.7.4 environment variable and pip to disk D. when I use it, I will add C: \ users \ XXX \ appdata \ local \ programs \ Python \ Python 36
Just move out the python.exe in. The two pip s should not be interconnected...
