可疑的几处是一、 /return/good.html点开后是个链接，需要账户密码；二、coords 后一长串，不知道是啥，三、最后一个注释，有un 跟 pw字样，明摆着是account and password ，因此尝试先从此入手。这是一个典型的bz2压缩后的字符，用bz2 反压缩看看

import bz2

un= b'BZh91AY&SYA\xaf\x82\r\x00\x00\x01\x01\x80\x02\xc0\x02\x00 \x00!\x9ah3M\x07<]\xc9\x14\xe1BA\x06\xbe\x084'
pw= b'BZh91AY&SY\x94$|\x0e\x00\x00\x00\x81\x00\x03$ \x00!\x9ah3M\x13<]\xc9\x14\xe1BBP\x91\xf08'
print(bz2.decompress(un))
print(bz2.decompress(pw))

输出：
b’huge’
b’file’

将 huge file 输入之前的框框，得到个新的页面：

标题是 ‘’connect the dots‘ 连点，图片中的黑点连起来看看

也没看出来是啥东西，囧，再看看源代码，太长不输了，里面有个first second，要求first+second。目前到此，无头绪了。

3天无灵感了，今天早上坐地铁，又翻了翻这个帖子，忽然想到是不是就是关键在connect the dots? 因为不可能让大家手动去连，所以，要连的估计是first 与 second，目前只会用matplotlib 画图，于是把 first 与 second 按顺序分成x,y, 然后试试：

from matplotlib import pyplot as plt

def list_rerrange(ls):
    dev_x = []
    dev_y = []
    for i in range(len(ls)):
        if i%2 == 0:
            dev_x.append(ls[i])
        else:
            dev_y.append(s[i])
    plt.scatter(dev_x, dev_y)
    plt.show()

first = [146,399,...,399]
second = [156,141,...,136]
list_rerrange(first + second)

画出来一个倒着的牛，改改y值把牛正过来看看：

from matplotlib import pyplot as plt

def list_rerrange(ls):
    dev_x = []
    dev_y = []
    for i in range(len(ls)):
        if i%2 == 0:
            dev_x.append(ls[i])
        else:
            dev_y.append(0-ls[i])
    plt.scatter(dev_x, dev_y)
    plt.show()

first = [146,399,...,399]
second = [156,141,...,136]
list_rerrange(first + second)
