python addon으로 Response 데이터 수정 및 보기

Request 데이터 보기

이번엔 Python Addon을 통해 Response 데이터 보는 방법과 Response 데이터 수정하는 방법을 알아보자

Mitmproxy 실행

$ mitmproxy -s {파이썬모듈경로/test.py} --set block_global=false

# test.py

from mitmproxy import ctx


class TestAddon:

    def __init__(self):
        pass

    def response(self, flow):
        if "myrealtrip" in flow.request.pretty_url :
            ctx.log.info(flow.response)

	 # 결과 : info: Response(200, application/json;charset=UTF-8, 1.35k)

    def response(self, flow):
    	""" 압축되지 않고 디코딩된 HTTP 메시지 본문을 텍스트로 보기 """

        if "myrealtrip" in flow.request.pretty_url :
            ctx.log.info(flow.response.get_text())
            
	# 결과 : {"data":[{"code":"RENTCAR_LIST_BANNER","banners":[{"id":857,"imageUrl":"https://d2ur7st6jjikze.cloudfront.net/cms/1729_original_1643098924.jpg?1643098924","mobileImageUrl":"https://d2ur7st6jjikze.cloudfront.net/cms /1730_original_1643098925.jpg?1643098925","webImageUrl":"https://d2ur7st6jjikze.cloudfront.net/cms/1729_original_1643098924.jpg?1643098924","link":"https://www.myrealtrip.com/promotions/rentacar_coupon_main","linkForWeb" :"https://www.myrealtrip.com/promotions/rentacar_coupon_main","linkForMobileWeb":"https://www.myrealtrip.com/promotions/rentacar_coupon_main","linkForIos":"mrt://web?url=https%3A%2F%2Fwww.myrealtrip.com%2Finstants%2Fprom otions%2Frentacar_coupon_main","linkForAndroid":"mrt://web?url=https%3A%2F%2Fwww.myrealtrip.com%2Finstants%2Fpromotions%2Frentacar_coupon_main"}]}],"meta":{},"result":{"status":200,"message":"SUCCESS","code":"success"}}

    def response(self, flow):
    	""" Response Json 객체 수정하기 """ 
        
        if "sampleURL" in flow.request.url:
            data = json.loads(flow.response.get_text()) # get_text로 Json 객체 로드
            data["data"]["vid"] = 9999                  # json 객체 내 value 수정
            flow.response.text = json.dumps(data)       # 수정한 데이터 리턴
            
	# 결과 : {"data": {"vid": 9999}}
