從google api golang 客戶端，我們注意到google-api-go-client/transport/http/configure_http2_go116.go//go:build go1.16// +build go1.16...// configureHTTP2 configures the ReadIdleTimeout HTTP/2 option for the// transport. This allows broken idle connections to be pruned more quickly,// preventing the client from attempting to re-use connections that will no// longer work.func configureHTTP2(trans *http.Transport) { http2Trans, err := http2.ConfigureTransports(trans) if err == nil { http2Trans.ReadIdleTimeout = time.Second * 31 }}而在這個文件中google-api-go-client/transport/http/configure_http2_not_go116.go //go:build !go1.16// +build !go1.16// configureHTTP2 configures the ReadIdleTimeout HTTP/2 option for the// transport. The interface to do this is only available in Go 1.16 and up, so// this performs a no-op.func configureHTTP2(trans *http.Transport) {}Pernet/http2/transport.go是ConfigureTransport很久以前添加的。// ConfigureTransport configures a net/http HTTP/1 Transport to use HTTP/2.// It returns an error if t1 has already been HTTP/2-enabled.//// Use ConfigureTransports instead to configure the HTTP/2 Transport.func ConfigureTransport(t1 *http.Transport) error {為什么在 go1.16 上為傳輸配置 ReadIdleTimeout HTTP/2 選項？

在golang.org/x/net/http2包中有兩個類似的探測函數，它們的作用非常不同：
func ConfigureTransport (t1 *http.Transport) error
func ConfigureTransports (t1 *http.Transport) (*Transport, error)
我認為您將前者與后者混淆了。

非常相似的名稱是不幸的，但它們會在 godoc 中彼此相鄰排序，并且復數的 ConfigureTransports 暗示了它的用途：它允許您配置 http 和 http2 傳輸。
ConfigureTransports僅在一年前推出：

http2: add ConfigureTransports
The ConfigureTransport function doesn't provide any way to get at the
http2 Transport it creates, making it impossible to configure transport
parameters such as ReadIdleTimeout.
