python逆コンパイルexeファイルはpyファイルの実例コードです。
私たちはpyinstallerで友達の書類をexeファイルに包装しますが、時々復元が必要です。pyinstxtractor.pyを使ってもいいです。
使い方:
そして使えます。
最後にpyinstxtractor.pyのコードを貼り付けます。
以上は小编が绍介したpython反コンパイルexeファイルのpyファイルの実例コードです。皆さんに助けてほしいです。もし何か疑问があれば、メッセージをください。小编はすぐに返事します。
使い方:
python pyinstxtractor.py xxx.exeこのような構造のフォルダを取得します。
--- xxx.exe_extracted
-- out00-PYZ.pyz_extracted
- .pyc
-- out00-PYZ.pyz
-- some
-- others
-- xxx( )pip install uncompyleにuncompyleをインストールし、そして使えます。
uncompyle6 input.pyc > output.pypycファイルをpyファイルに変換して、みんなに助けがあることを望みます。最後にpyinstxtractor.pyのコードを貼り付けます。

PyInstaller Extractor v1.9 (Supports pyinstaller 3.3, 3.2, 3.1, 3.0, 2.1, 2.0)
Author : Extreme Coders

This script extracts a pyinstaller generated executable file.
Pyinstaller installation is not needed. The script has it all.
For best results, it is recommended to run this script in the
same version of python as was used to create the executable.
This is just to prevent unmarshalling errors(if any) while
extracting the PYZ archive.
Usage : Just copy this script to the directory where your exe resides
and run the script with the exe file name as a parameter
C:\path\to\exe\>python pyinstxtractor.py <filename>
$ /path/to/exe/python pyinstxtractor.py <filename>

CHANGELOG
================================================
Version 1.1 (Jan 28, 2014)
-------------------------------------------------
- First Release
- Supports only pyinstaller 2.0
Version 1.2 (Sept 12, 2015)
-------------------------------------------------
- Added support for pyinstaller 2.1 and 3.0 dev
- Cleaned up code
- Script is now more verbose
- Executable extracted within a dedicated sub-directory
(Support for pyinstaller 3.0 dev is experimental)
Version 1.3 (Dec 12, 2015)
-------------------------------------------------
- Added support for pyinstaller 3.0 final
- Script is compatible with both python 2.x & 3.x (Thanks to Moritz Kroll @ Avira Operations GmbH & Co. KG)
Version 1.4 (Jan 19, 2016)
-------------------------------------------------
- Fixed a bug when writing pyc files >= version 3.3 (Thanks to Daniello Alto: https://github.com/Djamana)
Version 1.5 (March 1, 2016)
-------------------------------------------------
- Added support for pyinstaller 3.1 (Thanks to Berwyn Hoyt for reporting)
Version 1.6 (Sept 5, 2016)
-------------------------------------------------
- Added support for pyinstaller 3.2
- Extractor will use a random name while extracting unnamed files.
- For encrypted pyz archives it will dump the contents as is. Previously, the tool would fail.
Version 1.7 (March 13, 2017)
-------------------------------------------------
- Made the script compatible with python 2.6 (Thanks to Ross for reporting)
Version 1.8 (April 28, 2017)
-------------------------------------------------
- Support for sub-directories in .pyz files (Thanks to Moritz Kroll @ Avira Operations GmbH & Co. KG)
Version 1.9 (November 29, 2017)
-------------------------------------------------
- Added support for pyinstaller 3.3
- Display the scripts which are run at entry (Thanks to Michael Gillespie @ malwarehunterteam for the feature request)
