如何使用 go-chi 框架的 gzip 中間件啟用 gzip 壓縮？嘗試使用此處顯示的示例：https://github.com/go-chi/chi/issues/204但是當(dāng)我檢查curl時(shí)，我得到了這個(gè)：$ curl -H "Accept-Encoding: gzip" -I http://127.0.0.1:3333HTTP/1.1 405 Method Not AllowedDate: Sat, 31 Aug 2019 19:06:39 GMT我嘗試了代碼“hello world”：package mainimport (    "net/http"    "github.com/go-chi/chi"    "github.com/go-chi/chi/middleware")func main() {    r := chi.NewRouter()    r.Use(middleware.RequestID)    r.Use(middleware.Logger)    //r.Use(middleware.DefaultCompress) //using this produces the same result    r.Use(middleware.Compress(5, "gzip"))    r.Get("/", Hello)    http.ListenAndServe(":3333", r)}func Hello(w http.ResponseWriter, r *http.Request){    w.Header().Set("Content-Type", "text/html") //according to the documentation this must be here to enable gzip    w.Write([]byte("hello world\n"))}但是當(dāng)我嘗試用curl驗(yàn)證時(shí)，結(jié)果是一樣的$ curl -H "Accept-Encoding: gzip" -I http://127.0.0.1:3333HTTP/1.1 405 Method Not AllowedDate: Sat, 31 Aug 2019 19:06:39 GMT這是怎么回事？
