脚本内容

代码如下：

from mitmproxy import http, ctx
from multiprocessing import Lock
class Filter:
  def __init__(self, filter_info):
    self.log_info = ""
    self.mutex = Lock()
    self.filter_info = filter_info
    self.response_file = None
    self.switch_on = False
    self.log_file = "log.txt"
  def log(self, info) -> None:
    self.log_info += f"{info}\n\n"
  def write_log(self, mode="w+") -> None:
    self.mutex.acquire()
    with open(self.log_file, mode) as f:
      f.write(self.log_info)
    self.mutex.release()
  def is_target_flow(self, flow: http.HTTPFlow) -> bool:
    for info in self.filter_info:
      if info["str_in_url"] in flow.request.url:
        self.log_file = info["log_file"]
        self.switch_on = info["switch_on"]
        if info["response_file"] != None:
          self.response_file = info["response_file"]
        return True
    else:
      return False
  def modify_response(self, flow: http.HTTPFlow) -> http.HTTPFlow:
    if self.switch_on and self.response_file:
      with open(self.response_file, "r") as f:
        flow.response.content = f.read().encode()
    return flow
  def request(self, flow: http.HTTPFlow) -> None:
    if self.is_target_flow(flow):
      self.log_info = ""
      self.log(f"——METHOD——\n{flow.request.method}")
      self.log(f"——HOST——\n{flow.request.pretty_host}")
      self.log(f"——URL——\n{flow.request.pretty_url}")
      query = [i + ":" + flow.request.query[i] + "\n" for i in flow.request.query]
      self.log(f"——QUERY STRING——\n{''.join(query)}")
      if flow.request.urlencoded_form:
        form = [i + ":" + flow.request.urlencoded_form[i] + "\n" for i in flow.request.urlencoded_form]
        self.log(f"——FORM——\n{''.join(form)}")
      self.write_log()
  def response(self, flow: http.HTTPFlow) -> None:
    if self.is_target_flow(flow):
      self.log_info = ""
      self.log(f"——RESPONSE before modified——\n{flow.response.content.decode()}")
      flow = self.modify_response(flow)
      self.log(f"——RESPONSE after modified——\n{flow.response.content.decode()}")
      self.write_log(mode="a")
filter_info = [
  {
    "str_in_url": "getSimpleNews",
    "log_file": "getSimpleNews_log.txt",
    "switch_on": True,
    "response_file": "getSimpleNews_response.txt",
  },
  {
    "str_in_url": "getQQNewsComment",
    "log_file": "getQQNewsComment_log.txt",
    "switch_on": True,
    "response_file": None,
  }
]
addons = [
  Filter(filter_info)
]

使用方法

运行mitmproxy指定使用该脚本和端口号即可：

mitmproxy -p 6666 -s xxx.py

在mitmproxy运行时：

1. 会拦截url中包含str_in_url字符串的请求

2. 会把response.content修改为当前mitm运行所在目录下的response_file文件中的内容

3. 打印信息在当前mitm运行所在目录下的log_file文件中

4. 如果无需修改response设置switch_on为False即为开关关闭

5. 如果不修改response的话response_file需要写None

补充知识：mitmproxy 监听指定端口

安装

使用python3的安装方式

https://mitmproxy.org/

监听指定端口

例子：Presto SQL请求的监听

Presto地址：http://datacenter4:18080

mitmproxy命令（端口8484）

mitmproxy \

--mode reverse:http://datacenter4:18080 \

--listen-host datacenter4 \

--listen-port 8484 \

--replacements :~s:\/\/datacenter4/:\/\/datacenter4:18080/

然后JDBC访问Presto使用：jdbc:presto://datacenter4:8484
