js逆向 - pyexecjs 执行js编码异常

pyexecjs执行js代码中含有中文会出现编码异常

File "C:\python3\lib\subprocess.py", line 1238, in _readerthread
buffer.append(fh.read())
UnicodeDecodeError: 'gbk' codec can't decode byte 0xbd in position 38: illegal multibyte sequence

解决办法：
法1. 将中文部分取出 单独编码后替换
法2. 根据异常定位可知 File "C:\python3\lib\subprocess.py", line 1238, in _readerthread
buffer.append(fh.read())
是subprocess包内的编码问题， 修改内置 subprocess 文件的编码类型为 encoding='utf-8'

法3. 使用 js2py 第三方包执行js代码 示例如下:

# -*- coding: utf-8 -*-

import execjs
import js2py

jscode = '''function getnames(){
    window = {}
