python如何利用Mitmproxy抓包

一、使用

安装

pip install mitmproxy

• mitmproxy 是具有控制台界面的交互式，支持SSL的拦截代理
• mitmdump是mitmproxy的命令行版本。想想tcpdump为HTTP
• mitmweb 是一个基于web的界面，适用于mitmproxy
  

mitmproxy(mac)、mitmdump、mitmweb(win) 这三个命令中的任意一个即可

mitmweb -s mitm.py 命令行启动默认端口8080
mitmweb -p 8888 -s mitm.py 指定端口8888
ctrl+c退出

启动后设置电脑或手机代理(电脑ip，端口8888)，安装证书
打开 cmd，执行 "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --proxy-server=10.12.2.28:8888 --ignore-certificate-errors

二、过滤、修改

"""
flow.request.scheme 请求协议
flow.request.host 请求host
flow.request.url  请求URL链接
flow.request.method 请求方法
flow.request.query 请求URL查询参数
flow.request.path 请求URL https://www.baidu.com/ 
flow.request.path_components #请求URL不包含域名的元祖 ('project', 'classify', 'list')
flow.request.urlencoded_form 请求POST数据
flow.response.status_code HTTP响应状态码
flow.response.headers HTTP响应头信息
flow.response.get_text HTTP响应内容

"""
