[golang] Create a simple HTTP Server with golang

Creating a simple HTTP Server is quite easy with go, with a few lines of code to achieve this. Following up on our earlier blog on “Writing a simple application with golang” this post will guide you through the steps taken to create this service. Assuming the environment is setup and ready will go straight into business.

Writing a simple HTTP Server

We need to import 2 packages to do this;

import "fmt"
import "net/http"

Now, Create the handler which will be handling the incoming request; Here, we will be just printing “It’s Alive!!!”

func handler(w http.ResponseWriter, r *http.Request) {
   fmt.Fprint(w, "It's Alive!!!")
}

Now, Create the main function where it listens through port 8000 and redirect traffic coming into “/” to the created handler

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

and that’s it!.
The full code block is as below;
