案例一：Python-WEB 爬虫库&数据解析库
这里开发的内容不做过多描述，贴上自己写的代码
爬取数据
要爬取p标签，利用Beautyfulsoup模块
import requests,time
from bs4 import BeautifulSoup#url="https://src.sjtu.edu.cn/rank/firm/0/?page=2"
def get_content():for i in range (30,40):url="http://192.168.172.132/cms/show.php?id=%s"%iprint(url+'\n')try:response = requests.get(url)markup = response.text# print(markup)soup=BeautifulSoup(markup, "lxml")#divs = soup.find_all('div',attrs={'class','nav'})ps = soup.find_all('p')# print(ps)for p in ps:print(p.string+'\n')with open("examples.txt",'a+',encoding='utf-8') as file:file.write(p.string+'\n')except Exception as e:time.sleep(1)passif __name__ == "__main__":get_content()运行结果，把所有p标签的文字都输入到了文件中
案例二：Python-EDU_SRC-目标列表爬取
fofa挖掘数据，这里代码还可以优化，如果要挖掘更多数据可以带上cookie去访问
这里fofa搜索后面的参数就是的就是base64的编码值，所以可以直接搜好以后用url地址去跑
import requests
from bs4 import BeautifulSoup#获取页码
def get_pages():pages = soup.find('span',attrs={"class":"hsxa-highlight-color"})#print(pages.get_text().strip())page = int(int(pages.get_text().strip())/10)page = page + 1print("一共有%s页"%page)#获取网页(title)名
def get_titles():ps = soup.find_all('p',attrs={"class":"el-tooltip hsxa-one-line item"})for p in ps:print(p.string.strip())#获取ip名
def get_ips():ips = soup.find_all('span',attrs={"class":"hsxa-host"})#print(ips)for ip in ips:print(ip.a.get_text().strip())#获取指纹
def get_serves():servers = soup.find_all('span',attrs={"class":"el-tooltip hsxa-list-span hsxa-list-span-sm"})#print(servers)for server in servers:print(server.get_text().strip())if __name__ == "__main__":url = input("请输入fofa的url地址:")response = requests.get(url)markup = response.textsoup = BeautifulSoup(markup,"lxml")while(True):math = int(input("\n"+"获取页码输入1"+"\n"+"获取title输入2"+"\n"+"获取ip输入3"+"\n"+"获取指纹输入4"+"\n"+"退出请输入5"+"\n"))if math == 1:get_pages()if math == 2:get_titles()if math == 3:get_ips()if math == 4:get_serves()if math == 5:break运行结果
案例三: Python-FOFA_API-资产信息爬取
这里fafo自带有api接口可以利用去访问，不过呢这里需要fofa会员或者有F点才能够搜索，这里只能先贴上代码，没办法复现
import requests
import base64#https://fofa.info/api/v1/search/all?email=your_email&key=your_key&qbase64=dGl0bGU9ImJpbmcidef get_fofa_data(email,apikey):for eduname in open('eduname.txt',encoding='utf-8'):e=eduname.strip()search='"%s" && country="CN" && title=="Error 404--Not Found"'%eb=base64.b64encode(search.encode('utf-8'))b=b.decode('utf-8')url='https://fofa.info/api/v1/search/all?email=%s&key=%s&qbase64=%s'%(email,apikey,b)s=requests.get(url).json()print('查询->'+eduname)print(url)if s['size'] != 0:print(eduname+'有数据啦！')for ip in s['results']:print(ip[0])else:print('没有数据')if __name__ == '__main__':email='471656814@qq.com'apikey='0fccc926c6d0c4922cbdc620659b9a42'get_fofa_data(email,apikey)
