记一次简单的网站逆向自动签到

准备

Python 3.11.6
httpx 0.24.0

思路

F12浏览器调试-抓取POST请求-模仿发送请求-自动化

步骤

抓取POST

目标网站HiFiNi - 音乐磁场

F12开启开发者工具，点击签到按钮，筛选后发现仅有一个GET，推测是POST完毕之后自动重定向。

因此，在点击按钮后，立刻停止数据抓取即可。成功抓取到XHR。

XHR请求

点进去直接看payload：

1
2
3

{
    "sign": "xxxxxxxxxxxxxx"
}

响应为：

{
    "code": "-1",
    "message": "今天已经签过啦！"
}

构建请求

已经很久没用requests库了，我的项目现在都换成HTTPX了。这玩意是真好用，自带异步。

#!/usr/bin/python

import httpx
from time import sleep

url = "https://www.hifini.com/sg_sign.htm"

post_content = {
    "sign": "xxxxxxxxxxxxxx"
}
headers = {
    "accept"          : "text/plain, */*; q=0.01",
    "accept-encoding" : "gzip, deflate, br, zstd",
    "accept-language" : "zh-CN,zh;q=0.9,en-US;q=0.8,en;q=0.7,en-GB;q=0.6",
    "content-length"  : "69",
    "content-type"    : "application/x-www-form-urlencoded; charset=UTF-8",
    "cookie"          : "your_cookies",
    "origin"          : "https://www.hifini.com",
    "referer"         : "https://www.hifini.com/sg_sign.htm",
    "x-requested-with": "XMLHttpRequest"
}
cookies = {
    "bbs_sid"  : "your_bbs_sid",
    "bbs_token": "your_bbs_token"
}

with httpx.Client() as c:
    a = c.post(
        url=url,
        headers=headers,
        cookies=cookies,
        follow_redirects=True,
        data=post_content
    )
    print(a.text)
