Go에서 여러 HTTP 멀티플렉서를 어떻게 결합할 수 있나요?

<code class="go">rootMux := http.NewServeMux()
subMux := http.NewServeMux()

// Handle requests to /top_path/sub_path
subMux.HandleFunc("/sub_path", myHandleFunc)

// Strip the /top_path prefix from the URL before passing it to subMux
rootMux.Handle("/top_path/", http.StripPrefix("/top_path", subMux))

http.ListenAndServe(":8000", rootMux)</code>

<code class="go">import (
    "net/http"
)

// CombinedMux combines multiple http.ServeMux instances.
type CombinedMux struct {
    muxes []http.Handler
}

// ServeHTTP implements the http.Handler interface for CombinedMux.
func (c *CombinedMux) ServeHTTP(w http.ResponseWriter, r *http.Request) {
    for _, mux := range c.muxes {
        mux.ServeHTTP(w, r)
    }
}

func main() {
    muxA, muxB := http.NewServeMux(), http.NewServeMux()

    // Initialize muxA and muxB

    combinedMux := &CombinedMux{
        muxes: []http.Handler{muxA, muxB},
    }

    http.ListenAndServe(":8080", combinedMux)
}</code>
