猿人学web端爬虫攻防大赛赛题第4题——雪碧图、样式干扰

题目网址：https://match.yuanrenxue.cn/match/4

解题步骤

看触发的数据包。
响应数据中可以看到明显的图片base64编码，去一个值解码一下，可以得到图片。（https://the-x.cn/encodings/Base64.aspx）

看来这个页面是通过图片进行回显的，直接把响应数据中的所有图片base64编码保存为图片。

import requests
import re
import os
import base64

if not os.path.exists('img'):
	os.mkdir('img')

url = "https://match.yuanrenxue.cn/api/match/4?page=1"
resp = requests.get(url)
resp_content = resp.text
pattern = r'base64,(.*?)\"'
findall = re.findall(pattern, resp_content)
index = 1
lst = []
for item in findall:
	lst.append(item)
for i in range(len(lst)):
	lst[i] = lst[i].replace("\\", "")
for i in lst:
	with open("./img/{}.png".format(index), mode="wb") as file:
		file.write(base64.b64decode(i))
	index += 1

在img文件夹里生成了55张图片，我们去跟页面上的数据对应一下，明显不是一一对应的。

这是怎么回事呢，回到页面，查看页面元素。

发现有些图片是不显示的，肯定是做了什么判断。
找数据包的initiator模块，有个request方法。

点进去看看。

代码复制出来，整理一下如下。

$.ajax({
		url: window.url, dataType: "json", async: false, data: list, type: "GET", beforeSend: function (request) {
		}, success: function (data) {
			datas = data.info;
			$('.number').text('').append(datas);
			var j_key = '.' + hex_md5(btoa(data.key + data.value).replace(/=/g, ''));
			$(j_key).css('display', 'none');
			$('.img_number').removeClass().addClass('img_number')
		}, complete: function () {
		}, error: function () {
			alert('因未知原因，数据拉取失败。可能是触发了风控系统');
			alert('生而为虫，我很抱歉');
			$('.page-message').eq(0).addClass('active');
			$('.page-message').removeClass('active')
		}
	})

可以看到class为j_key的元素不可显示，看下j_key是如何生成的。
var j_key = '.' + hex_md5(btoa(data.key + data.value).replace(/=/g, ''))
涉及到data.key、data.value、btoa和hex_md5两个变量和两个函数，看下分别是什么，在var j_key处打断点，让程序运行到这里。
再看数据包，发现跟页面响应内容中的key和value一致。
两个变量搞清楚了，再看两个函数。
btoa：base64编码函数

hex_md5：根据名字，是个md5算法，测试一下是不是没魔改过的md5算法。(进行md5之前要把base64编码后的等号给删除)

一致，说明就是个普通的md5算法。

知道怎么过滤不要的图片后，编写代码。(由于相同数字的图片的base64编码是一致的，所以可以利用一个字典先行存储)

	res_png_lst = []  # 最终需要的图片
	res_style_lst = []  # 最终图片对应的位置

	temp = ""   # 用于拼接
	for png in res_png_lst:
		temp += number_dict[png]
	print(temp)

运行结果如下。

跟页面的数据对照一下，发现也不太对。

看看哪里还有问题，回到页面元素，在style里面存在玄机。

页面的回显内容就不是一一对应的。
接下来就要解决图片顺序的问题了，经过多次尝试，终于发现了规律。
一个td标签的宽度为45.36，一个数字的宽度为11，所以一个td标签最多只能放4位数字。

我们将45.36视为46，除以4，以11.5为基准，每一张图片按照它的顺序分别加上倍数的11.5。例如，td标签中的第一个img标签让它的style加上一倍的11.5。（要排除掉不可见的图片）

td标签中的第二个img标签让它的style加上两倍的11.5。

知道了规律之后，编写代码按照顺序拼接数字。
