背景:
1.公司專案,沒有前端專案,無法起前端,無法驗證本地介面
2.介面鑑權OATH2,使用postman除錯每次都要取瀏覽器複製Authorization頭,還會頻繁過期,影響效率
方案:使用MITMProxy自定義流量處理
MITMProxy是一種用於中間人攻擊(Man-in-the-middle attack)的代理工具。它的作用是在正常的代理功能基礎上,截獲、記錄或篡改資料,並自定義特定的行為。與其他抓包工具(如Fiddler或Wireshark)不同的是,MITMProxy不僅可以檢視和分析截獲的請求,還可以透過自定義指令碼進行二次開發。例如,可以截獲瀏覽器對特定URL的請求,將返回內容置空並儲存真實的返回內容到資料庫,並在出現異常時傳送郵件通知。與Fiddler類似的需求無法實現高度定製化,而MITMProxy可透過載入自定義Python指令碼輕鬆實現。
安裝:brew install mitmproxy
指令碼:
# mitmproxy script to intercept and modify requests from mitmproxy import http import os TOKEN_FILE_PATH = "/Users/xy/workspace/python/mitmproxy/token_file.txt" LOG_FILE_PATH = "/Users/xy/workspace/python/mitmproxy/log_file.txt" def save_log_to_file(log): with open(LOG_FILE_PATH, "a") as file: file.writelines(log+"\n") def save_token_to_file(token): with open(TOKEN_FILE_PATH, "w") as file: file.write(token) def load_token_from_file(): if os.path.exists(TOKEN_FILE_PATH): with open(TOKEN_FILE_PATH, "r") as file: token = file.read().strip() return token return None def request(flow: http.HTTPFlow) -> None: #儲存dev的鑑權 # Check if the host is a.com and save the token if "dev-oa.xx.com" in flow.request.pretty_host: save_log_to_file('---->dev-oa.xx.com') token = flow.request.headers.get("Authorization") if token: save_log_to_file('save token') save_log_to_file(token) save_token_to_file(token) # Modify the request URL to dev_a.com # flow.request.host = "dev_a.com" # Check if the host is b.com and inject the token #使用儲存的鑑權覆蓋本地的請求 elif "127.0.0.1" in flow.request.pretty_host: save_log_to_file('---->127.0.0.1') token = load_token_from_file() if token: save_log_to_file('token') save_log_to_file(token) flow.request.headers["Authorization"] = token #將dev的前端請求轉發給本地 # Replace dev-oa.xx.com/flow with 127.0.0.1:9099 if "dev-oa.xx.com/flow/h5" in flow.request.pretty_url or "dev-oa.xx.com/flow/admin" in flow.request.pretty_url: # if False: flow.request.host = "127.0.0.1" flow.request.port = 9099 flow.request.scheme = "http" flow.request.path = flow.request.path.replace("/flow", "",1)
啟動:mitmproxy -s modify_request.py -p 8089
注意那兩個檔案的許可權
然後在系統設定代理 127.0.0.1 8089
