HTTP/2 Server
1) Generate a self-signed X.509 TLS certificate
Run the following command to generate cert.pem and key.pem files:
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.
2) Create a handler which simply outputs the request information to the client
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
sc := echo.StartConfig{Address:":1323"}
if err := sc.StartTLS(context.Background(), e,"cert.pem","key.pem"); err !=nil{
e.Logger.Error("failed to start server","error", 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
Protocol: HTTP/2.0
Host: localhost:1323
Remote Address: [::1]:60288
Method: GET
Path: /
