python安全开发

前言

目的：想快速的搜集edu的域名

一、平台edu

https://src.sjtu.edu.cn/rank/firm/0/?page=2

二、使用步骤

1.引入库

代码如下（示例）：

Get_EduName.py

import requests //爬虫
from bs4 import BeautifulSoup //提取数据
from concurrent.futures import ThreadPoolExecutor, as_completed  //多进程
import csv //csv

2.功能

def get_edu_name(page):url = f'https://src.sjtu.edu.cn/rank/firm/0/?page={page}'try:print(f'正在获取第{page}页的数据...')response = requests.get(url)if response.status_code == 200:soup = BeautifulSoup(response.text, 'lxml')edu1 = soup.find_all('td', attrs={'class': 'am-text-center'})edu_names = []for td in edu1: //找到tdif td.a:  //找到a标签institution_name = td.a.get_text()edu_names.append(institution_name)return edu_nameselse:print(f'Failed to retrieve page {page}. Status code: {response.status_code}')return []except Exception as e:print(f'Failed to retrieve page {page}: {e}')return []

写入数据

def extract_unique_universities(filename):unique_universities = set()universities_list = []with open(filename, 'r', encoding='utf-8-sig') as f:reader = csv.reader(f)for row in reader:if row:  # 确保行不为空university_name = row[0].strip()  # 取第一列数据，并去除空格if university_name not in unique_universities:unique_universities.add(university_name)universities_list.append(university_name)return universities_list
if __name__ == '__main__':max_pages = 100  # 设置要获取的页面数edu_names = get_all_edu_names(max_pages)save_edu_names_to_csv(edu_names, 'edu.csv')print("学校名称已保存到 edu.csv 文件中。")filename = 'edu.csv'  # 替换为你的 CSV 文件路径universities = extract_unique_universities(filename)print("提取的大学数据:")for university in universities:print(university)with open('university.txt', 'a+', encoding='utf-8') as f:f.write(university + '\n')

Get_Edu_domain.py
原理从bing里面搜索关键字，提取网址，写入csv

效果

可以使用这里的子域名写入到一个文件
可以使用subfinder,httpx,ksubdomain,

./subfinder -d baidu.com -silent|./ksubdomain -verify -silent|./httpx -title -content-length -status-code -o url.html -html

总结

可以批量打edu的域名，快速上分edu
