Adding Another Page With Go Handlers
To add another page, we added another “handler”.
Notice how each path is associated with a “handler”:
/ = homeHandler
/contact = contactHandler
Here is the source code:
package main
import (
"fmt"
"net/http"
)
func homeHandler(w http.ResponseWriter, r *http.Request) {
w.Header().Set("Content-Type", "text/html; charset=utf-8")
w.Header().Add("Fake", "my fake header")
fmt.Fprint(w, "<h1> Welcome to my site </h1>")
}
func contactHandler(w http.ResponseWriter, r *http.Request) {
w.Header().Set("Content-Type", "text/html; charset=utf-8")
fmt.Fprint(w, "<h1> Contact Page </h1><p> To get in touch, email me at <a href=\"mailto:rabocse@alexrabocse.me\"> rabocse@alexrabocse.me </a>.")
}
func main() {
http.HandleFunc("/", homeHandler)
http.HandleFunc("/contact", contactHandler)
fmt.Println("Starting the server on :3000...")
http.ListenAndServe(":3000", nil)
}
Here is a quick verification with “curl”:
❯ curl localhost:3000/contact
<h1> Contact Page </h1><p> To get in touch, email me at <a href="mailto:rabocse@alexrabocse.me"> rabocse@alexrabocse.me </a>.
❯ curl localhost:3000/
<h1> Welcome to my site </h1>
