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:

  1. go run $GOROOT/src/crypto/tls/generate_cert.go --host localhost

For demo purpose, we are using a self-signed certificate. Ideally, you should obtaina certificate from CA.

Step 2: Create a handler which simply outputs the request information to the client

  1. e.GET("/request", func(c echo.Context) error {
  2.   req := c.Request()
  3.   format := `
  4.     <code>
  5.       Protocol: %s<br>
  6.       Host: %s<br>
  7.       Remote Address: %s<br>
  8.       Method: %s<br>
  9.       Path: %s<br>
  10.     </code>
  11.   `
  12.   return c.HTML(http.StatusOK, fmt.Sprintf(format, req.Proto, req.Host, req.RemoteAddr, req.Method, req.URL.Path))
  13. })

Step 3: Configure TLS server using cert.pem and key.pem

  1. e.StartTLS(":1323", "cert.pem", "key.pem")

Step 4: Start the server and browse to https://localhost:1323/request to see the following output

  1. Protocol: HTTP/2.0
  2. Host: localhost:1323
  3. Remote Address: [::1]:60288
  4. Method: GET
  5. Path: /
