How would you implement middleware in a Go HTTP handler?
- By defining a custom middleware function.
- By using the built-in http.Middleware package.
- By wrapping each HTTP route with a separate router.
- Middleware cannot be implemented in Go.
Middleware in Go HTTP handlers is typically implemented by defining custom middleware functions. These functions can be applied to specific routes or globally to the entire application to perform tasks such as logging, authentication, and request/response modification before reaching the actual HTTP handler for a route. Middleware functions are executed in the order they are added, allowing for sequential processing of requests.
