Actix File Server with API Key Authentication

This is a simple, yet powerful Actix file server written in Rust, which provides file access through a secure API key authentication mechanism. It serves files from a local directory while ensuring that only trusted web services can access them.

Features

• Actix Web framework for efficient and fast web server
• API key authentication for secure file access
• Customizable local directory for serving files
• Path sanitization to prevent directory traversal attacks
• Environment variable-based configuration

Setup

• Clone the repository to your local machine.
• Set the required environment variables:

• APIKEY: The API key to be used for authentication.

• SOCKET: The address and port the server should bind to (e.g., 127.0.0.1:8080).
• Run the server using cargo run.

Usage

To access a file from the server, send a GET request to the server with the desired file path and include the x-api-key header with the correct API key.

Example:

GET /path/to/file.txt
x-api-key: yourapikey

If the provided API key is correct and the file exists, the server will return the file. Otherwise, it will return an error with the appropriate status code.
