Python执行js字符串常见方法示例

pip insatll js2py
# 获取执行JS的环境
context = js2py.EvalJs()  
# 加载执行
context.execute('放JS字符代码')

import execjs
print(execjs.get().name)
# node.js (V8)

import execjs
user_id = '3232597584'
url = f'https://www.toutiao.com/toutiao/api/pc/feed/?min_behot_time=1588149898&cateGory=__all__&utm_source=toutiao&widen=1&tadrequire=true&user_id={user_id}&visited_uid={user_id}'
js_index = """
js
"""
# 打开js文件读取
# new_url = execjs.compile(open("/Users/ts/Desktop/Jeff/今日头条/new_sign.js").read()).call('get_sigtrue', url)  
# 读取js字符串
new_url = execjs.compile(js_index).call('get_sigtrue', url)  
print(new_url)
