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td
                if td.a:  //找到a标签
                    institution_name = td.a.get_text()
                    edu_names.append(institution_name)
            return edu_names
        else:
            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

完整代码

import requests
from bs4 import BeautifulSoup
import csv
import tldextract
import concurrent.futuresGet_Edu_domain.py

headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:98.0) Gecko/20100101 Firefox/98.0',
    'cookie': 'MUID=32957CB67A1A615722B972087B656099'
}

university_list = []


with open('university.txt', 'r', encoding='utf-8') as f:
    for line in f:
        university_list.append(line.strip().replace(' ', '+'))


with open('university_results.csv', 'w', newline='', encoding='utf-8-sig') as csvfile:
    csvwriter = csv.writer(csvfile)
    csvwriter.writerow(['大学', '网址', '子域名'])  

    def process_site(site):
        url = f'https://www.bing.com/search?q=intitle%3a{site}&mkt=zh-CN&FPIG=0B6AED8B37BF44B78B8F58E6A949DB10&first=1&FORM=PERE'

        print(f"正在搜索: {site}")

        try:
            response = requests.get(url, headers=headers)
            print(f"状态码: {response.status_code}")

            response.encoding = 'utf-8'
            soup = BeautifulSoup(response.text, 'lxml')
            results = soup.find_all('h2')

            found_valid_result = False

            for result in results:
                try:
                    u = result.a.get('href')
                    print(f"网址: {u}")

                    # 提取子域名
                    extracted = tldextract.extract(u)
                    if extracted.subdomain:
                        domain = f"{extracted.subdomain}.{extracted.domain}.{extracted.suffix}"
                        if '.edu.cn' in domain or domain.endswith('.edu.cn'):
                            csvwriter.writerow([site, u, domain]) 
                            found_valid_result = True
                            break  

                except Exception as e:
                    print(f"提取网址时出错: {e}")

            if not found_valid_result:
                print("未找到有效的搜索结果。")
                csvwriter.writerow([site, '未找到有效结果', ''])  

        except requests.RequestException as e:
            print(f"请求失败: {e}")
            csvwriter.writerow([site, f"请求失败: {e}", ''])  

        except Exception as e:
            print(f"出错: {e}")
            csvwriter.writerow([site, f"出错: {e}", '']) 

    
    with concurrent.futures.ThreadPoolExecutor() as executor:
        executor.map(process_site, university_list)

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
