blackbox-logger 0.1.2

Framework-agnostic HTTP logger with payload masking

🕵️‍♂️ BlackBox Logger

A universal request/response logger for Django, Flask, FastAPI, and other Python apps.
Automatically logs requests and responses, user info, IP address, and more — with masked sensitive data — into a log file and SQLite database.

---

🚀 Features

• ✅ Logs all HTTP requests and responses
• ✅ Logs to both blackbox.log file and SQLite DB (blackbox_logs.db)
• ✅ Automatically masks sensitive fields (e.g., password, token, etc.)
• ✅ Logs user (if available), IP address, and user agent
• ✅ Skips HTML content in logs to avoid noise
• ✅ Works out-of-the-box in Django
• ⚙️ Easy integration in Flask and FastAPI

📦 Installation

pip install blackbox-logger
Or install directly from GitHub:

pip install git+https://github.com/avi9r/blackbox_logger.git

📁 Logs

• After running, you’ll find:

📄 log/blackbox.log — clean file logs

🗃 log/blackbox_logs.db — SQLite DB (table: logs)

⚙️ Usage

🟩 Django

• Add middleware:

your_project/middleware.py

    from django.utils.deprecation import MiddlewareMixin
    from blackbox_logger.logger import HTTPLogger

    logger = HTTPLogger()

    class BlackBoxLoggerMiddleware(MiddlewareMixin):
        def process_request(self, request):
            logger.log_request(
                request.method,
                request.path,
                dict(request.headers),
                request.body,
                request
            )

        def process_response(self, request, response):
            logger.log_response(
                request.method,
                request.path,
                dict(request.headers),
                response.content,
                response.status_code,
                request
            )
            return response

Enable middleware in settings.py:

MIDDLEWARE = [
    'your_project.middleware.BlackBoxLoggerMiddleware',
    ...
]

🟦 Flask

(Optional) Install Flask-Login for user tracking:

pip install flask-login

Initialize the logger in app.py:

from flask import Flask, request
from flask_login import current_user
from blackbox_logger.logger import HTTPLogger

logger = HTTPLogger(
    get_user=lambda headers, request=None: current_user.username if current_user.is_authenticated else "Anonymous"
)

app = Flask(__name__)

@app.before_request
def log_req():
    logger.log_request(
        request.method,
        request.path,
        dict(request.headers),
        request.get_data(),
        request
    )

@app.after_request
def log_resp(response):
    logger.log_response(
        request.method,
        request.path,
        dict(request.headers),
        response.get_data(),
        response.status_code,
        request
    )
    return response

🟨 FastAPI

• Add middleware in main.py:

from fastapi import FastAPI, Request, Response
from blackbox_logger.logger import HTTPLogger

logger = HTTPLogger()

app = FastAPI()

@app.middleware("http")
async def blackbox_logger_middleware(request: Request, call_next):
    # Optional: Attach user to request.state (e.g., after auth)
    request.state.user = "Anonymous"

    body = await request.body()
    logger.log_request(request.method, str(request.url), dict(request.headers), body, request)

    response = await call_next(request)
    response_body = b"".join([chunk async for chunk in response.body_iterator])
    response.body_iterator = iter([response_body])

    logger.log_response(request.method, str(request.url), dict(request.headers), response_body, response.status_code, request)
    return response

🔐 Masking Sensitive Data

• By default, the following fields are masked:

["password", "token", "access_token", "secret", "authorization", "csrfmiddlewaretoken"]

• You can update this in masking.py if needed.
