How to convert a string to a valid URL-encoded string using strconv in Golang?

In Go, you can use the net/url package to convert a string to a valid URL-encoded string. You don't need to use the strconv package for URL encoding.

Here's an example of how you can convert a string to a URL-encoded string:

package main

import (
	"fmt"
	"net/url"
)

func main() {
	str := "Hello, World!"
	encodedStr := url.QueryEscape(str)
	fmt.Println(encodedStr)
}

In this example, the url.QueryEscape function is used to encode the string Hello, World! to a valid URL-encoded string "Hello%2C+World%21". The encoded string is then printed to the console.

You can run this code and it will print the URL-encoded string.
