Golang : Parsing or breaking down URL

Golang provides an easy way to consume and parse URL. It has a very neat package ( http://golang.org/pkg/net/url ) that deals with URL and allow developers to break down the URL into meaningful fragments for processing. The codes below will demonstrate how easy it is to parse a raw URL.

 package main

 import (
 "fmt"
 "net/url"
 "strings"
 )

 func main() {

 rawURL := "http://username:[email protected]:8080/testpath/?q=socketloop.com#TestFunc"

 fmt.Println("URL : ", rawURL)

 // Parse the URL and ensure there are no errors.
 url, err := url.Parse(rawURL)
 if err != nil {
 panic(err)
 }

 // see http://golang.org/pkg/net/url/#URL
 // scheme://[userinfo@]host/path[?query][#fragment]

 // get the Scheme
 fmt.Println("Scheme : ", url.Scheme)

 // get the User information
 fmt.Println("Username : ", url.User.Username())

 password, set := url.User.Password()
 fmt.Println("Password : ", password)
 fmt.Println("Password set : ", set)

 // get the Host
 fmt.Println("Raw host : ", url.Host)

 // to get the Port number, split the Host
 hostport := strings.Split(url.Host, ":")
 host := hostport[0]
 port := hostport[1]

 fmt.Println("Host : ", host)
 fmt.Println("Port : ", port)

 // get the Path
 fmt.Println("Path : ", url.Path)

 // get the RawQuery
 fmt.Println("Raw Query ", url.RawQuery)

 // get the fragment
 fmt.Println("Fragment : ", url.Fragment)

 }

Output :

URL : http://username:[email protected]:8080/testpath/?q=socketloop.com#TestFunc

Scheme : http

Username : username

Password : password

Password set : true

Raw host : searchengine.com:8080

Host : searchengine.com

Port : 8080

Path : /testpath/

Raw Query q=socketloop.com

Fragment : TestFunc
