C++ Web Server with Route Management and File Provider

This is a simple multithreaded web server implemented in C++ using the Asio library. It supports basic route management, logging (similar to Nginx access logs), and secure file serving from a designated folder.

Features

• Route management: Define custom routes that respond to specific HTTP requests.
• File provider: Serve static files from a folder (/public by default) with proper path sanitization to prevent directory traversal attacks.
• Logging: Logs HTTP requests in the Nginx-style access log format, with both console and file logging.
• Multithreading: Each request is handled in a separate thread to improve performance.

Dependencies

• Xmake build system
• C++17 or later
• Asio (provided by xmake)

Getting Started

1. Clone the Repository

git clone <repository-url>
cd <repository-folder>

2. Build the Project with Xmake

Install Xmake

If you don't have Xmake installed, you can install it by following the instructions from the Xmake website.

Build the Project

After installing Xmake, you can build the project by running:

xmake

This will compile the project and generate the executable in the build directory.

4. Run the Server

Once the project is built, run the server:

xmake run WebServer

The server will start listening on port 8080 by default. You can access it via http://localhost:8080.

5. Accessing Routes

• / - Responds with a welcome message: "Welcome to the homepage!"
• /about - Responds with "This is the about page."
• /public/* - Serves static files located in the ./public folder. Example: http://localhost:8080/public/file.txt.

6. Logging

Logs are saved in an access.log file in the project root directory. Logs follow the Nginx access log style:

<client-ip> - - [timestamp] "GET <route>" <status>

Example:

127.0.0.1 - - [18/Oct/2024:14:32:45 +0000] "GET /about" 200 OK

Adding Routes

You can define your own custom routes in the main() function:

server.addRoute("/custom", []() {
    return "This is a custom route!";
});

Serving Files

To serve files securely, define a route prefix (like /public) and a folder to serve files from. For example:

server.addFileProviderRoute("/public", "./public");

This will serve files located in the ./public folder at the URL /public/<filename>.
