Golang - How to validate URL

URLvalidatorExample.go

import (
"fmt"
"github.com/asaskevich/govalidator"
)

// You can use as well instead of *url.URL a string with your URL, in this case you might drop `u.String()`
// - transformation to string in method call.
func validateURL(u *url.URL) error {
	valid := govalidator.IsRequestURL(u.String())
	if valid == false {
		return fmt.Errorf("%v is a invalid url", u.String())
	}
	return nil
}

Your solution passes for if "://" part is missing after scheme I believe?

Thanks

import "net/url"
u, err := url.ParseRequestURI("https://google.com/")
if err != nil {
// Handle error
}

Try this:

for _, u := range []string{`http://`, `https://`, `http://goo`} {
	_, err := url.ParseRequestURI(u)
	if err != nil {
		fmt.Println(u+`:`, err)
	}
}
