How do you read cookies in an HTTP request with an HTTP client in Go?

client := &http.Client{
    Transport: &http.Transport{},
}

req, err := http.NewRequest("GET", "https://www.example.com", nil)
if err != nil {
    // handle error
}

resp, err := client.Do(req)
if err != nil {
    // handle error
}
defer resp.Body.Close()

cookies := resp.Cookies()
for _, cookie := range cookies {
    fmt.Printf("Cookie: %s=%s\n", cookie.Name, cookie.Value)
}

In this example, an http.Client is created with a http.Transport. An http.Request is then created with the http.NewRequest() function.

The request is sent with the http.Client's Do() method, and the response is stored in the resp variable. The Cookies() method is then called on the http.Response object to get a slice of *http.Cookie pointers.

The for loop is then used to iterate over each cookie in the slice, and the cookie name and value are printed to the console.

Note that cookies can only be read from an http.Response object, not from an http.Request object. If you want to send cookies with a subsequent request, you can create a new http.Cookie struct and add it to the http.Client's Jar field, as described in the previous answer.
