经典的execjs打开js编码错误

import subprocess
from functools import partial

subprocess.Popen = partial(subprocess.Popen, encoding="utf-8")
import  execjs

使用python拿到node异步js的值

import subprocess
p = subprocess.check_output(['node', 'encrypt.js'])
print(p.decode())

# 2
p = subprocess.check_output(['node', '-e', js])
# js是字符串，在js 里面console.log() 结果就行了
