How to handle a POST request in GO?

Question

JavaScript

I process requests in the north like this:

func main() {
  http.HandleFunc("/news", GetNews)
  http.ListenAndServe(":8000", nil)
}

func GetNews(w http.ResponseWriter, req *http.Request) {
   if req.Method == "POST" {
    fmt.Println("Work")
  }
}

And send like this:

document.querySelector('button').addEventListener('click', () => {
                var xhr = new XMLHttpRequest();
                xhr.open('POST', '/news', true);
                xhr.send();
                if (xhr.status != 200) {
                    console.log( xhr.status + ': ' + xhr.statusText ); 
                } else {
                    console.log(JSON.parse(xhr.responseText)); 
                }
            })

AJAX goes to the server, but for some reason it is not processed there. How to be?

Answer 1

In Go, everything is fine, but in js you send an asynchronous request, but process it synchronously, so you cannot get the result, but the request successfully goes to the server and is processed there.
