如何在golang中获取实际的本地化/ lang？

Question

There is function who return localize/lang in golang ? Something like HTTP_ACCEPT_LANGUAGE in PHP

I wanted to make a dynamically changing language page but i can't find this.

Answer 1

r.Header.Get("Accept-Language") is what you are looking for.

The function will return something like: en-US,en;q=0.8,ro;q=0.6

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

func index(w http.ResponseWriter, r *http.Request) {        
    if r.Method == "GET" {
        fmt.Println(r.Header.Get("Accept-Language"))
    }
}

And the corresponding $_SERVER['HTTP_ACCEPT_LANGUAGE'] php function will return the same information: en-US,en;q=0.5.
