Description

In Go 1.22.0 The http.Request type added methods PathValue and SetPathValue which are used to handle named path wildcards in URL routes.

func ArticlesCategoryHandler(w http.ResponseWriter, r *http.Request) {
    w.WriteHeader(http.StatusOK)
    fmt.Fprintf(w, "Category: %v\n", r.PathValue("category"))  // by r.PathValue
}
