Mitmproxy 最新新版配置上游代理

由于在 4.0版本之后flow.live.change_upstream_proxy_server(proxy)方法已经弃用，

会引发：

AttributeError: 'NoneType' object has no attribute 'change_upstream_proxy_server'

使用flow.server_conn.via = ServerSpec(("http", proxy))方法配置上游代理

from mitmproxy import http
import requests
from mitmproxy import ctx

from mitmproxy.net.server_spec import ServerSpec


class MitmProxy:
    def __init__(self):
        self.name = 'mitmproxy'

    def request(self, flow: http.HTTPFlow):
        # if the decision is done by domain, one could alse modify the server address here.
        # We do it after CONNECT here to have the reqeust data available as well.
        
        client_ip = flow.client_conn.address[0]
        if 'get' in flow.request.url: 
            
            ip_ = '上游代理ip：str'
            port_ = '上游代理端口：int'
            proxy = (ip_, int(port_))

            flow.server_conn.via = ServerSpec(("http", proxy))

addons = [
    MitmProxy()
]

        

然后直接使用在命令行运行Mitmproxy

mitmdump -s 绝对路径/mitmdump.py -p 端口
