一个依赖node.js来执行js代码的python库

Project description

一个依赖node.js来执行js代码的库


环境

注意 需要安装好node.js, 并添加好环境变量!!!


安装

pip install pyevaljs3

快速开始

import pyevaljs3

js_code = "function f(args) {console.log(args); return 'ok';}; return f('args')"
result = pyevaljs3.eval_(js_code)
print(result) # 'ok'

js_code = "function f(arg1, arg2) {console.log(arg1, arg2); return arg1 + arg2;}"
ctx = pyevaljs3.compile_(js_code)
result = ctx.call('f', 'a', 'b')
print(result) # 'ab'

#另一钟传参方式
result = ctx.call('f', arg_list=['a', 'b'])
print(result) # 'ab'

API参考

pyevaljs3.JSEval

  • def compile(self, source: str = None, suffix: str = None):
       编译javascript源代码
       :param source: 源代码字符串或要读取的文件路径
       :param suffix: js脚本文件名后缀(指定以什么模式执行), 默认是".js", 可选的值还有".cjs", ".mjs"等
       :return: Context

  • def eval(self, code: str = None, ignore_output=False):
       执行javascript代码, 返回其结果


pyevaljs3.Context

  • def call(self, func, *args, arg_list: List = None):
       调用指定的函数, 返回其结果(若指定了arg_list, 优先使用它作为函数参数)
       :param func: 函数名
       :param args: 函数的参数列表
       :param arg_list: 函数的参数列表

pyevaljs3的模块级函数

  • def compile_(source: str = None, mode: str = None) -> Context:
       编译js源代码
       :param source: 源代码字符串或要读取的文件路径
       :param mode: 执行模式, 默认以.js的行为去执行
       :return: Context

  • def eval_(code: str = None, ignore_output=False):
       执行javascript代码, 返回其结果
       :param code: js代码
       :param ignore_output: 是否忽略执行过程中的输出, 若为True则仅返回其结果, 默认不忽略(False)


使用自定义版本的node

  • 通过设置坏境变量来使用自定义版本的node, 只需设置NODE_PATH、NODE坏境变量即可
import os
# 优先级最高
os.environ['NODE_PATH'] = '/path/to/node.exe'
# 或者
# 优先级其次
os.environ['NODE'] = '/path/to/node.exe'
