数据接口分析
数据接口 https://match.yuanrenxue.cn/api/match/15
请求时需要携带 page 页码，m为加密参数
cookie中没有加密信息，携带 SessionId请求即可
加密参数还原
查看数据接口对应的 requests 栈
m参数 是通过 window.m() 方法执行后得到的
打上断点，查看 window.m() 方法执行了什么
instance = results.instance;
window.q = instance.exports.encode;
window.m = function (){t1 = parseInt(Date.parse(new Date())/1000/2);t2 = parseInt(Date.parse(new Date())/1000/2 - Math.floor(Math.random() * (50) + 1));return window.q(t1, t2).toString() + '|' + t1 + '|' + t2;
};
window.q = instance.exports.encode;
window.q 是请求 wasm 文件编译成的，可以在 python 调用 wasm 文件
# 首先将 wasm 二进制的文件保存到本地
import requests
response = requests.get('https://match.yuanrenxue.cn/static/match/match15/main.wasm').content
open('15.wasm', 'wb').write(response)
调用
def get_m():t1 = int((int(time.time()) * 1000) / 1000 / 2)t2 = int((int(time.time()) * 1000) / 1000 / 2 - random.randint(10, 60))result = pywasm.load('15.wasm')results = result.exec("encode", [t1, t2])return f'{results}|{t1}|{t2}'
