猿人学第十五题：备周则意怠-常见则不疑

题目链接：https://match.yuanrenxue.cn/match/15

翻页看看请求⬇️

点击Payload旁边的旁边的旁边的Initiator，再点击req对应的js进入打上断点⬇️

 网上翻一点看到script标签里面是WebAssembly，请求也可以看到wasm文件⬇️

 

 从wasm文件点过去，在567行打上断点，再次翻页断点到此处⬇️

 t1和t2很好实现，鼠标放在window.q上，点击框框处进入函数定义的地方⬇️

 这里看不懂没关系，使用python的wasmtime包（pip install wasmtime）解决，完整代码如下：

import json
import random
import time

import requests
import wasmtime.loader
import module  # type:ignore


def get_wasm_m():
    """调用WASM模块的encode函数生成带时间戳的编码结果"""
    t1 = int(time.time() / 2)
    t2 = int(time.time() / 2 - random.randint(1, 50))
    result = module.encode(t1, t2)
    ress = '|'.join([str(result), str(t1), str(t2)])
    return ress
