Overview

net/url package of golang contains a Parse function that can be used to parse a given and return the url instance of the URL struct

https://golang.org/pkg/net/url/#URL

Once the given URL is parsed correctly, then it will return the URI object. We can then access the below information from the URI

Scheme

User Info

Hostname

Port

Pathname

Query Params

Fragment

Let’s see a working program for the same:

We will parse the below URL

https://test:[email protected]:8000/tutorials/intro?type=advance&compact=false#history

Then

Scheme is HTTPS

User Info – username is test and password is abcd123. Username and password are separated by a colon :

Hostname is www.golangbyexample.com

Port is 8000

The path is tutorials/intro

Query Params is type=advance and compact=false. They are separated by ampersand

fragment is history. It will directly take to the history section within that page. history is an identifier that refers to that section within that page

Program

package main
import (
"fmt"
"log"
"net/url"
)
func main() {
input_url := "https://test:[email protected]:8000/tutorials/intro?type=advance&compact=false#history"
u, err := url.Parse(input_url)
if err != nil {
log.Fatal(err)
}
fmt.Println(u.Scheme)
fmt.Println(u.User)
fmt.Println(u.Hostname())
fmt.Println(u.Port())
fmt.Println(u.Path)
fmt.Println(u.RawQuery)
fmt.Println(u.Fragment)
fmt.Println(u.String())
}

Output

https
test:abcd123
golangbyexample.com
8000
/tutorials/intro
type=advance&compact=false
history
https://test:[email protected]:8000/tutorials/intro?type=advance&compact=false#history

It correctly dumps all the information as seen from the output
