Article Server

A Flask-based HTTP server that provides access to news articles stored in a directory structure, with time-based filtering and outlet-specific querying capabilities.

Overview

This server allows you to query news articles from various sources based on:

• Time range (last hour, day, week, month)
• Specific news outlets
• Direct content retrieval by file path

Articles are organized in a nested directory structure where each news outlet has its own subdirectory containing the respective articles.

Directory Structure

The server expects the following directory structure:

scraper/
└── articles/
    ├── Reuters – Business News/
    │   ├── article1.txt
    │   ├── article2.txt
    │   └── ...
    ├── Associated Press – Business/
    │   ├── article1.txt
    │   └── ...
    └── ...

Security Notes

• The server validates that all requested file paths are within the configured article directory to prevent directory traversal attacks
• All file paths must be absolute and within the allowed directory structure
• Path parameters are URL decoded for proper handling of special characters

Requirements
