ASP.NET Core Middleware Documentation

Overview

The ASP.NET Core middleware framework allows you to separate concerns and implement decoupled logic. It provides a flexible way to handle requests and responses, enhancing the maintainability and scalability of your applications.

Key Features

Request Routing: Middleware handles incoming requests and directs them to specific handlers.
Response Handling: Middleware modifies responses before they are sent to the client.
Middleware Functions: Each middleware function provides a specific task – authentication, authorization, logging, etc.
Middleware Types: Various middleware types (e.g., middleware, route middleware) cater to different scenarios.

Example: Authentication Middleware

This middleware handles user authentication and authorization. It verifies a user's identity before allowing access to protected resources.

It might check for a valid JWT token, or a user's credentials.

The authentication logic is implemented in a separate middleware function.

Example: Logging Middleware

This middleware logs all incoming requests, providing detailed information about each request's status and data.

This helps in debugging and monitoring application performance.

Code Example (Conceptual - Requires Further Development)

This is a conceptual example - the actual implementation would involve defining middleware functions.
