使用到包 pyexecjs：pip install pyexecjs

Windows 环境

import execjs

js_file1 = open('js文件1').read()
js_file2 = open('js文件1').read()
tmp = execjs.compile((js_file1 + js_file2))
cmd = 'password_encrypt("", "")'.format('参数1'， '参数2')
passwd_js = tmp.eval(cmd)

Linux 环境

提前安装 Node 环境，以 Centos 7.5.1804 为例：yum install nodejs -y

import os
import execjs

os.environ["EXECJS_RUNTIME"] = "Node"
node = execjs.get()
js_file = open("经过修改的JS文件").read()
tmp = node.compile(js_file)
passwd_js = tmp.call('函数名', '参数1'， '参数2')

关于 nodejs 中有报错 CryptoJS is not defined 问题，由于对 JS 不太懂，只写处理方式，有兴趣的可查看末尾参考原文。

;(function (root, factory) {
    if (typeof exports === "object") {
        // CommonJS
        module.exports = exports = factory();
    }
    else if (typeof define === "function" && define.amd) {
        // AMD
        define([], factory);
    }
    else {
        // Global(browser)
        root.CryptoJS = factory();
    }
...

改为

var CryptoJS;
;(function (root, factory) {
    CryptoJS = factory();
    if (typeof exports === "object") {
        // CommonJS
        module.exports = exports = factory();
    }
    else if (typeof define === "function" && define.amd) {
        // AMD
        define([], factory);
    }
    else {
        // Global(browser)
        root.CryptoJS = factory();
    }
...
