Comment puis-je enregistrer les réponses HTTP dans une application Web Go à l'aide de Gorilla Mux et des gestionnaires ?

func logResponse(next http.Handler) http.Handler {
    return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
        // Capture the request
        requestBytes, err := httputil.DumpRequest(r, true)
        if err != nil {
            http.Error(w, err.Error(), http.StatusInternalServerError)
            return
        }
        log.Printf("%q", requestBytes)

        // Create a new ResponseRecorder to capture the response
        rec := httptest.NewRecorder()
        next.ServeHTTP(rec, r)

        // Capture the response
        responseBytes := rec.Body.Bytes()
        log.Printf("%q", responseBytes)

        // Copy the recorder's headers and body into the original ResponseWriter
        for k, v := range rec.HeaderMap {
            w.Header()[k] = v
        }
        w.WriteHeader(rec.Code)
        w.Write(responseBytes)
    })
}

// Import Gorilla packages
import (
    "github.com/gorilla/mux"
    "github.com/gorilla/handlers"
)

func main() {
    // Setup Gorilla router
    r := mux.NewRouter()

    // Wrap the handler with the logging middleware
    wrappedHandler := handlers.LoggingHandler(os.Stdout, http.HandlerFunc(handler))

    // Register the handler with the router
    r.Handle("/api/v1/users", wrappedHandler)

    // Start the server
    http.ListenAndServe(":8080", r)
}
