The Go language implements simple Web server methods

This article illustrates how the Go language implements a simple Web server. Share with you for your reference. The specific analysis is as follows:

The package http responds to HTTP requests with any value that implements http.Handler:
package http
type Handler interface {
ServeHTTP(w ResponseWriter,
r *Request)
}

In this example, the type Hello implements http.Handler.
Note: this example does not work on the web-based tutorial user interface. To try to write an web server, you might need to install Go.

package main

import (

    "fmt"

    "net/http"

)

type Hello struct{}

func (h Hello) ServeHTTP(

        w http.ResponseWriter,

        r *http.Request) {

    fmt.Fprint(w, "Hello!")

}

func main() {

    var h Hello

    http.ListenAndServe("localhost:4000",h)

}

I hope this article has helped you with the Go programming language.
