HTTP/2 Recipe
How to run an HTTP/2 server? 🔗
Step 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
For demo purpose, we are using a self-signed certificate. Ideally, you should obtain a certificate from CA.
Step 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))
})
Step 3: Start TLS server using cert.pem
and key.pem
🔗
if err := e.StartTLS(":1323", "cert.pem", "key.pem"); err != http.ErrServerClosed {
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)
}
Step 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: /
