Python执行js代码

# -*- coding: utf-8 -*-
import execjs
ctx = execjs.compile(''' function test () {
        var s = [];
        var hexDigits = "0123456789abcdef";
        for (var i = 0; i < 36; i++) {
            s[i] = hexDigits.substr(Math.floor(Math.random() * 0x10), 1);
        }
        s[14] = "4"; // bits 12-15 of the time_hi_and_version field to 0010
        s[19] = hexDigits.substr((s[19] & 0x3) | 0x8, 1); // bits 6-7 of the clock_seq_hi_and_reserved to 01
        s[8] = s[13] = s[18] = s[23] = "-";
        var uuid = s.join("");
        return uuid;
    }''')


#此处的'test'为js的函数名称
print(ctx.call('test'))
