解题步骤

按照要求，写一个python脚本跑即可：

import re
from time import sleep

import requests

url = "http://a43ceadd-9f52-41a5-8fd5-d40bb82a8035.node4.buuoj.cn:81/"
headers = {
    "Cookie":"PHPSESSID=1cibn7jnm8mv5idbkknq24tjb2"
}
for i in range(0, 1000):
    res = requests.get(url=url, headers=headers)
    if res.status_code != 200:
        sleep(1)
        res = requests.get(url=url, headers=headers)
    print(i)
    num = res.text.count("Coffee")
    data = {
        "num":num-1
    }
    res2 = requests.post(url=url, data=data, headers=headers)
print(res2.text)
