折腾：
【未解决】mac中electron-python用PyInstaller去打包可执行文件
看到打包期间生成的二进制pyc文件了：
打包目的是防止别人看到源代码
而印象中，python的pyc也是可以被反编译的
所以此处顺带去看看：
是否很容易把此处pyc反编译出源码
pyc 反编译
pyc python3 反编译
pyc python3 decompile
结果：
可能有部分代码没有反编成功！
反编译失败。
只支持python2，此处自己是python 3，且是最新的3.8.0
永远等待中。放弃。
python文件反编译失败，鄙人能力有限，后期增强改进！
试了2次，结果：
要么是504错误
要么是：Error: Unknown error:0

去对比源码：
除了个别问题和缺点：
- 个别代码逻辑导致逻辑变化：
-
- 注释丢失
之外，主体代码逻辑，全都在。
从反编译角度来说，可以说成功复原代码达95%左右
可以这么说：成功率和准确率极高。效果极其好。
顺带再去反编译另外4个文件，大概对比看看效果是否也这么好。

【总结】
python代码，（比如PyInstaller打包）编译后的文件是：*.pyc
（其他类似二进制目标文件：*.pyo）
都可以用：
去反编译出来。
安装：
git clone https://github.com/rocky/python-uncompyle6.git pip install -e .
用法：
反编译pyc，输出结果到当前终端中
uncompyle6 xxx.pyc
举例：
uncompyle6 ../pyc/mitmdumpOtherApi.cpython-38.pyc
总体效果：非常完美
- 优点
- 代码的结构和函数和变量名，都完美的反编译出来了
- 和源代码，一模一样
- 总体来说，有95%的代码，都可以完美的解析出来
- 问题
- 代码缩进错误，导致后续代码逻辑不对
- 部分代码（函数）无法解析，报错
- 注释无法保留
- 这个是正常现象
补充：
（1）把反编译结果 输出到py文件：
uncompyle6 ../pyc/mitmdumpOtherApi.cpython-38.pyc > ../pyc/mitmdumpOtherApi.py
（2）具体语法详见-h帮助信息：
uncompyle6 -h
Usage:
uncompyle6 [OPTIONS]... [ FILE | DIR]...
uncompyle6 [--help | -h | --V | --version]
Examples:
uncompyle6 foo.pyc bar.pyc # decompile foo.pyc, bar.pyc to stdout
uncompyle6 -o . foo.pyc bar.pyc # decompile to ./foo.pyc_dis and ./bar.pyc_dis
uncompyle6 -o /tmp /usr/lib/python1.5 # decompile whole library
Options:
-o <path> output decompiled files to this path:
if multiple input files are decompiled, the common prefix
is stripped from these names and the remainder appended to
<path>
uncompyle6 -o /tmp bla/fasel.pyc bla/foo.pyc
-> /tmp/fasel.pyc_dis, /tmp/foo.pyc_dis
uncompyle6 -o /tmp bla/fasel.pyc bar/foo.pyc
-> /tmp/bla/fasel.pyc_dis, /tmp/bar/foo.pyc_dis
uncompyle6 -o /tmp /usr/lib/python1.5
-> /tmp/smtplib.pyc_dis ... /tmp/lib-tk/FixTk.pyc_dis
--compile | -c <python-file>
attempts a decompilation after compiling <python-file>
-d print timestamps
-p <integer> use <integer> number of processes
-r recurse directories looking for .pyc and .pyo files
--fragments use fragments deparser
--verify compare generated source with input byte-code
--verify-run compile generated source, run it and check exit code
--syntax-verify compile generated source
--linemaps generated line number correspondencies between byte-code
and generated source output
--encoding <encoding>
use <encoding> in generated source according to pep-0263
--help show this message
Debugging Options:
--asm | -a include byte-code (disables --verify)
--grammar | -g show matching grammar
--tree={before|after}
-t {before|after} include syntax before (or after) tree transformation
(disables --verify)
--tree++ | -T add template rules to --tree=before when possible
Extensions of generated files:
'.pyc_dis' '.pyo_dis' successfully decompiled (and verified if --verify)
+ '_unverified' successfully decompile but --verify failed
+ '_failed' decompile failed (contact author for enhancement)【后记】
关于从py打包，比如用py2exe，则也是有破解工具的：
“Extract .pyc files from executables created with py2exe”
所以，这些打包方式没有太安全的。。
本身也很难安全。
