猿人学_第15题

进入开发者工具

下面的请求为真实的数据请求

请求方式: GET
参数：m: 16759391|832956713|832956708
---------page : 1

进入ajax调用点

看到m是经过一个fetch请求返回得到的

而fetch请求的是一个wasm文件

wasm文件是经过C/C++/RUST/Go等多种语言编写智能合约并编译成字节码文件
这样我们就无法看懂了
但是python中有第三方库可以对wasm文件进行解析
执行pip install pywasm

那么我们只需要下载请求时的main.wasm文件，然后在python中调用该库来进行调用其中的函数即可

步骤

1. 下载请求中的main.wasm文件到本地
2. 根据js代码中，获取t1和t2
3. 将其传入到exec函数中，获取r进行拼接获取m
4. 将m拼接到url中再拼接page即可
   代码如下

import math
import random
import time

import pywasm
import requests

runtime = pywasm.load('./main.wasm')

t1 = int(int(time.time()) / 2)
t2 = int(int(time.time()) / 2 - math.floor(random.random() * (50) + 1))
r = runtime.exec('encode', [t1, t2])
m = str(r) + '|' + str(t1) + "|" + str(t2)
