Golang : How to redirect to new page with net/http?

Problem :

You need to do a page redirect in Golang. How to do it ?

Solution :

Use net/http package Redirect() function.

For example :

Example 1:

 package main

 import (
 "log"
 "net/http"
 )

 func redirect(w http.ResponseWriter, r *http.Request) {

 http.Redirect(w, r, "http://www.golang.org", 301)
 }

 func main() {
 http.HandleFunc("/", redirect)
 err := http.ListenAndServe(":8080", nil)
 if err != nil {
 log.Fatal("ListenAndServe: ", err)
 }
 }

Example 2:

 func viewHandler(w http.ResponseWriter, r *http.Request) {
 title := r.URL.Path[len("/view/"):]
 p, err := loadPage(title)
 if err != nil {
 http.Redirect(w, r, "/edit/"+title, http.StatusFound)
 return
 }
 renderTemplate(w, "view", p)
 }
