You're developing a RESTful API using Gorilla Mux. How would you implement authentication middleware to protect certain routes?
- Implement a custom middleware function to check authentication status before handling the request.
- Implement a role-based access control (RBAC) system within the application to manage access to specific routes based on user roles.
- Integrate third-party authentication services like OAuth2 to handle authentication for the API routes.
- Use the built-in middleware provided by Gorilla Mux to authenticate requests.
Authentication middleware in Gorilla Mux can be implemented by creating a custom middleware function that checks the authentication status before handling the request. This function can verify the presence of authentication tokens or session cookies, and reject unauthorized requests. Using built-in middleware or third-party services may not offer the flexibility needed for custom authentication logic.
