执行JS字符串

方法

执行大型js时有点慢
特殊编码的输入或输出参数会出现报错，解决方法：
	可以把输入或输出的参数用base64编码一下。base64都是英文和数字，没有特殊字符了

1--js2py

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')

2--execjs

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)

3--execjs

import execjs

def get_js():
    f = open("./new_sign.js", 'r', encoding = 'UTF-8')
    line = f.readline()
    htmlstr = ''
    while line:
        htmlstr = htmlstr + line
        line = f.readline()
    return htmlstr

jsstr = get_js()
ctx = execjs.compile(jsstr)
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}'
print(ctx.call('getUrl', url))
