英文:
HTTP2 not enabled by default on localhost
问题
我可能对此一无所知，但是我的基本本地服务器由于某种奇怪的原因没有启用HTTP2。通常我会在Caddy后面使用代理，但是由于我不想在这个项目中使用我的域名，所以我创建了一个基本的Go服务器并运行它，它工作得很好，但是头部显示的是HTTP/1.1而不是2.0，出了什么问题？
package main
import (
"fmt"
"net/http"
"html/template"
"os"
)
func IfError(err error, Quit bool) {
if err != nil {
fmt.Println(err.Error())
if(Quit) {
os.Exit(1);
}
}
}
func ServeHome(w http.ResponseWriter, r *http.Request) {
t, err := template.ParseFiles("html/home")
IfError(err, false)
err = t.Execute(w, nil)
IfError(err, false)
}
func RedirectRoot(fs http.Handler, home http.Handler) http.Handler {
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
if r.URL.Path == "/" {
home.ServeHTTP(w, r)
} else {
fs.ServeHTTP(w, r)
}
})
}
func main() {
proto := ":8081"
ServeFiles := http.FileServer(http.Dir("static/"))
http.Handle("/", RedirectRoot(ServeFiles, http.HandlerFunc(ServeHome)))
fmt.Printf("Listening on ... %s", proto)
IfError(http.ListenAndServe(proto, nil), true)
}
非常基础的东西，但是即使文档说默认情况下它可以工作，但实际上并不起作用。另外，我的Go版本是1.8.3。

I might be just clueless on this but my basic localhost server doesn't have HTTP2 Enabled for some odd reason, I normally proxy behind Caddy, but as I don't want to use my domain for this side project, I created a basic server in Go, and ran it, it works okay, but the headers show HTTP/1.1 instead of 2.0, what's wrong?
package main
import (
"fmt"
"net/http"
"html/template"
"os"
)
func IfError(err error, Quit bool) {
if err != nil {
fmt.Println(err.Error())
if(Quit) {
os.Exit(1);
}
}
}
func ServeHome(w http.ResponseWriter, r *http.Request) {
t, err := template.ParseFiles("html/home")
IfError(err, false)
err = t.Execute(w, nil)
IfError(err, false)
}
func RedirectRoot(fs http.Handler, home http.Handler) http.Handler {
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
if r.URL.Path == "/" {
home.ServeHTTP(w, r)
} else {
fs.ServeHTTP(w, r)
}
})
}
func main() {
proto := ":8081"
ServeFiles := http.FileServer(http.Dir("static/"))
http.Handle("/", RedirectRoot(ServeFiles, http.HandlerFunc(ServeHome)))
fmt.Printf("Listening on ... %s", proto)
IfError(http.ListenAndServe(proto, nil), true)
}
Very basic stuff, but doesn't work even thought the documentation says it works by default. Also, my go version is 1.8.3

是的，当你使用SSL证书时，默认情况下启用了HTTP/2协议支持。
err := http.ListenAndServeTLS(":8081", "server.crt", "server.key", handler)
if err != nil && err != http.ErrServerClosed {
log.Fatal("ListenAndServe: ", err)
}
然后，通过以下方式访问：
https://localhost:8081/
英文:
Yes, its enabled by default when you use with SSL certs.
> Doc Reference: Starting with Go 1.6, the http package has transparent
> support for the HTTP/2 protocol when using HTTPS.
err := http.ListenAndServeTLS(":8081", "server.crt", "server.key", handler)
if err != nil && err != http.ErrServerClosed {
log.Fatal("ListenAndServe: ", err)
}
Then, access it via
https://localhost:8081/
