Connecting to the HTTP server

The previous recipe, Connecting to the remote server, gave us an insight into how to connect the TCP server at a lower level. In this recipe, communication with the HTTP server at a higher level will be shown.

 

How to do it...

1. Open the console and create the folder chapter07/recipe04.
2. Navigate to the directory.
3. Create the http.go file with the following content:

        package main

        import (
          "fmt"
          "io/ioutil"
          "net/http"
          "net/url"
          "strings"
        )

        type StringServer string

        func (s StringServer) ServeHTTP(rw http.ResponseWriter,
                                        req *http.Request) {
          req.ParseForm()
          fmt.Printf("Received form data: %v\n", req.Form)
          rw.Write([]byte(string(s)))
        } 

        func createServer(addr string) http.Server {
          return http.Server{
            Addr: addr,
            Handler: StringServer("Hello world"),
          }...
