如何使我的Web服务器用Golang编写，以支持HTTP/2服务器推送？

http。推送推送

这附带一个警告：您必须直接从您的服务器提供HTTP2流量。

// In the case of HTTP1.1 we make use of the `Link` header
// to indicate that the client (in our case, NGINX) should
// retrieve a certain URL.
//
// See more at https://www.w3.org/TR/preload/#server-push-http-2.
func handleIndex(w http.ResponseWriter, r *http.Request) {
  var err error

  if *http2 {
    pusher, ok := w.(http.Pusher)
    if ok {
      must(pusher.Push("/image.svg", nil))
    }
  } else {
    // This ends up taking the effect of a server push
    // when interacting directly with NGINX.
    w.Header().Add("Link", 
      "</image.svg>; rel=preload; as=image")
  }

  w.Header().Add("Content-Type", "text/html")
  _, err = w.Write(assets.Index)
  must(err)
}
