How to Follow Location with Cookie in Go

In Go, you can encounter situations where an HTTP response to a request redirects (HTTP code 302) and sets a cookie. To handle this scenario, you may want to follow the new location with the received cookie.

To accomplish this:

1. Import the cookiejar Package:

<code class="go">import "golang.org/x/net/publicsuffix"
import "net/http/cookiejar"</code>

2. Create a New Cookie Jar:

<code class="go">jar, err := cookiejar.New(&cookiejar.Options{
        PublicSuffixList: publicsuffix.List,
    })
if err != nil {
    log.Fatal(err)
}</code>

3. Create an HTTP Client with the Cookie Jar:

<code class="go">client := http.Client{Jar: jar}</code>

4. Send the HTTP Request:

<code class="go">resp, err := client.Get("http://dubbelboer.com/302cookie.php")
if err != nil {
    log.Fatal(err)
}</code>

5. Access the Response Data:

<code class="go">data, err := ioutil.ReadAll(resp.Body)
resp.Body.Close()
if err != nil {
    log.Fatal(err)
}

log.Println(string(data))</code>

By utilizing the cookiejar, Go ensures that the client follows the redirection and maintains the cookie during the process, allowing you to handle cookie-based redirections effectively.
