How can I handle http requests of different methods to / in Go?

Question

To ensure that you only serve the root: You’re doing the right thing. In some cases you would want to call the ServeHttp method of an http.FileServer object instead of calling NotFound; it depends whether you have miscellaneous files that you want to serve as well.

To handle different methods differently: Many of my HTTP handlers contain nothing but a switch statement like this:

switch r.Method {
case http.MethodGet:
    // Serve the resource.
case http.MethodPost:
    // Create a new record.
case http.MethodPut:
    // Update an existing record.
case http.MethodDelete:
    // Remove the record.
default:
    http.Error(w, "Method not allowed", http.StatusMethodNotAllowed)
}

Of course, you may find that a third-party package like gorilla works better for you.
