pythonchallenge Level 17

第17关地址：http://www.pythonchallenge.com/pc/return/romance.html

账号：huge 密码：file

页面是cookie，猜测与cooike相关

左下角是第4关图片：http://www.pythonchallenge.com/pc/def/linkedlist.php

第4关是follow the chain，所以需要连续读取cookie的信息

查看cookie发现一个info信息：you should have followed busynothing...

使用第4关的地址，url改成busynothing

http://www.pythonchallenge.com/pc/def/linkedlist.php?busynothing=12345

import re
from urllib.request import urlopen
from bs4 import BeautifulSoup

infoText = []
def findurl(url):
    html = urlopen(url)
    text = html.info()["Set-Cookie"]
    reg = re.compile('info=(.*); exp')
    info = ''.join(reg.findall(text))
    print(info)
    infoText.append(info)
    bsobj = BeautifulSoup(html, "html.parser")
    info = bsobj.text
    num = info.split(" ")[-1]
    if num.isdigit():
        url = "http://www.pythonchallenge.com/pc/def/linkedlist.php?busynothing=" + str(num)
        print(url)
        findurl(url)
    else:
        print(info)

url = "http://www.pythonchallenge.com/pc/def/linkedlist.php?busynothing=12345"
findurl(url)

修改脚本，把获取到的info信息拼起来，解码

import bz2
import re
from urllib import parse
from urllib.request import urlopen
from bs4 import BeautifulSoup

def findurl(url):
    html = urlopen(url)
    text = html.info()["Set-Cookie"]
    print(text)
    reg = re.compile('info=(.*); exp')
    info = ''.join(reg.findall(text))
    infoText.append(info)
    bsobj = BeautifulSoup(html, "html.parser")
    info = bsobj.text
    num = info.split(" ")[-1]
    if num.isdigit():
        url = "http://www.pythonchallenge.com/pc/def/linkedlist.php?busynothing=" + str(num)
        print(url)
        findurl(url)
    else:
        print(info)

url = "http://www.pythonchallenge.com/pc/def/linkedlist.php?busynothing=12345"
infoText = []
findurl(url)
newInfo = "".join(infoText)
# newInfo = "BZh91AY%26SY%94%3A%E2I%00%00%21%19%80P%81%11%00%AFg%9E%A0%20%00hE%3DM%B5%23%D0%D4%D1%E2%8D%06%A9%FA%26S%D4%D3%21%A1%EAi7h%9B%9A%2B%BF%60%22%C5WX%E1%ADL%80%E8V%3C%C6%A8%DBH%2632%18%A8x%01%08%21%8DS%0B%C8%AF%96KO%CA2%B0%F1%BD%1Du%A0%86%05%92s%B0%92%C4Bc%F1w%24S%85%09%09C%AE%24%90"
print(bz2.decompress(parse.unquote_to_bytes(newInfo.replace('+', '%20'))).decode('ascii'))

得到提示信息

is it the 26th already? call his father and inform him that "the flowers are on their way". he'll understand.

百度查莫扎特的父亲 Leopold Mozart

call his father，使用13关 pb.phone("Leopold")

获得提示：no! i mean yes! but ../stuff/violin.php.

打开：http://www.pythonchallenge.com/pc/stuff/violin.php

显示了莫扎特父亲的画像

根据之前提示：inform him that "the flowers are on their way"

cookie的info带上the flowers are on their way

import requests

url = "http://www.pythonchallenge.com/pc/stuff/violin.php"
headers = {
    'Cookie': 'info=the flowers are on their way'
}
response = requests.request("GET", url, headers=headers)
print(response.text)

打印返回信息可以看到
