HTTP/2 Server
原文：https://echo.labstack.com/docs/cookbook/http2
1) Generate a self-signed X.509 TLS certificate
Run the following command to generate cert.pem and key.pem files:
1
| go run $GOROOT/src/crypto/tls/generate_cert.go --host localhost
|
NOTE
For demo purpose, we are using a self-signed certificate. Ideally, you should obtain a certificate from CA.

| e.GET("/request", func(c echo.Context) error {
req := c.Request()
format := `
<code>
Protocol: %s<br>
Host: %s<br>
Remote Address: %s<br>
Method: %s<br>
Path: %s<br>
</code>
`
return c.HTML(http.StatusOK, fmt.Sprintf(format, req.Proto, req.Host, req.RemoteAddr, req.Method, req.URL.Path))
})
|
3) Start TLS server using cert.pem and key.pem

log.Fatal(err)

or use customized HTTP server with your own TLSConfig

| s := http.Server{
Addr: ":8443",
Handler: e, // set Echo as handler
TLSConfig: &tls.Config{
//Certificates: nil, // <-- s.ListenAndServeTLS will populate this field
},
//ReadTimeout: 30 * time.Second, // use custom timeouts
}
if err := s.ListenAndServeTLS("cert.pem", "key.pem"); err != http.ErrServerClosed {
log.Fatal(err)
}
|
4) Start the server and browse to https://localhost:1323/request to see the following output
