How to make http.redirect() to redirect automatically when executed

Question

With this code it show me a link to click for redirect to /hello, how do i make it redirect without user interaction?

package main
import (
    "fmt"
    "net/http"
)

func main() {
    r := http.NewServeMux()

    r.HandleFunc("/", index)
    r.HandleFunc("/hello", hello)

    http.ListenAndServe(":80", r)
}

func index(w http.ResponseWriter, r *http.Request) {
    http.Redirect(w, r, "/hello", 200)
}
func hello(w http.ResponseWriter, r *http.Request) {
    fmt.Println("hello")
}

You are passing status code 200 which is a "success" status code called "OK". Redirections are done with 3xx status codes, like 301, 302, 307... List of common redirection codes pre-declared in Go can be found here: pkg.go.dev/net/[email protected]#StatusIMUsed. And you can read more on the topic here: developer.mozilla.org/en-US/docs/Web/HTTP/Redirections and more on statuses: developer.mozilla.org/en-US/docs/Web/HTTP/Status — mkopriva

Thanks, the standard for redirect after a successful operation (like login/register) is 308? — mirko sailorm

@mirkosailorm i would argue that the correct one is 303 for that case: evertpot.com/http/303-see-other . 307 is definitely not correct. — Evert

As already answered in the comments, the standard HTTP code to be returned in case of a redirect is 303. So the redirect line should be:

http.Redirect(w, r, "/hello", http.StatusSeeOther)

Also note, using http package http.XXX is preferred to writing HTTP codes directly
