前言

mitmproxy 可以抓到请求后重定向到另外一个地址,也可以自定义返回的 response 内容

重定向请求

在实际工作中,调试接口的时候,有时候需要把线上的接口地址替换成本地地址去调试接口,可以用转发域名的方式

"""Redirect HTTP requests to another server."""
from mitmproxy import http


def request(flow: http.HTTPFlow) -> None:
# pretty_host takes the "Host" header of the request into account,
# which is useful in transparent mode where we usually only have the IP
# otherwise.
if flow.request.pretty_host == "example.org":
flow.request.host = "mitmproxy.org"

mock 返回指定数据

抓到对应接口,也可以指定返回 response 内容

"""Send a reply from the proxy without sending any data to the remote server."""
from mitmproxy import http


def request(flow: http.HTTPFlow) -> None:
if flow.request.pretty_url == "http://example.com/path":
flow.response = http.Response.make(
200, # (optional) status code
b"Hello World", # (optional) content
{"Content-Type": "text/html"}, # (optional) headers
)

也可以使用response函数重写返回

from mitmproxy import http

def response(flow: http.HTTPFlow):
if "http://httpbin.org/get" in flow.request.url:
# 状态码
print(f'状态码: {flow.response.status_code}')
# 返回内容,已解码
print(f'返回内容: {flow.response.text}')
# 返回内容, bytes类型
print(f'返回内容bytes类型: {flow.response.content}')
# 取得响应的文本
print(f'应的文本: {flow.response.get_text}')
# 修改响应 的文本
flow.response.set_text('{"code": 0, "message": "success"}')
