Parsing and building a URL

In many cases, it is better to manipulate a URL with the use of handy tools than trying to handle it as a simple string. Go standard libraries naturally contain the utilities to manipulate a URL. This recipe will go through some of these major functions.

How to do it...

1. Open the console and create the folder chapter07/recipe05.
2. Navigate to the directory.
3. Create the url.go file with the following content:

        package main

        import (
          "encoding/json"
          "fmt"
          "net/url"
        )

        func main() {

          u := &url.URL{}
          u.Scheme = "http"
          u.Host = "localhost"
          u.Path = "index.html"
          u.RawQuery = "id=1&name=John"
          u.User = url.UserPassword("admin", "1234")

          fmt.Printf("Assembled URL:\n%v\n\n\n", u)

          parsedURL, err := url.Parse(u.String())
          if err != nil {
            panic(err)
          }
          jsonURL, err := json.Marshal(parsedURL)
   ...
