Creating the HTTP Server

The creation of the HTTP server in Go is very easy, and the standard library provides more ways of how to do that. Let's look at the very basic one.

How to do it...

1. Open the console and create the folder chapter09/recipe04.
2. Navigate to the directory.
3. Create the httpserver.go file with the following content:

        package main

        import (
          "fmt"
          "net/http"
        )

        type SimpleHTTP struct{}

        func (s SimpleHTTP) ServeHTTP(rw http.ResponseWriter,
                            r *http.Request) {
          fmt.Fprintln(rw, "Hello world")
        }

        func main() {
          fmt.Println("Starting HTTP server on port 8080")
          // Eventually you can use
          // http.ListenAndServe(":8080", SimpleHTTP{})
          s := &http.Server{Addr: ":8080", Handler: SimpleHTTP{}}
          s.ListenAndServe()
        }

4. Execute the code by go run httpserver.go.
5. See the output:

6. Access the URL http://localhost:8080 in a browser or...
