如何在Golang中查看cookieJar的内容？

I'm trying to view the contents of a cookieJar response from a request to google:

package main

import (
    "fmt"
    "log"
    "net/http"
    "net/http/cookiejar"
    "net/url"
)

func main() {

    jar, err := cookiejar.New(nil)
    if err != nil {
        log.Fatal(err)
    }
    client := http.Client{Jar: jar}
    resp, err := client.Get("https://accounts.google.com/ServiceLogin?continue=https%3A%2F%2Fwww.youtube.com%2Fsignin%3Ffeature%3Dsign_in_button%26hl%3Den%26action_handle_signin%3Dtrue%26next%3D%252F%26app%3Ddesktop&service=youtube&sacu=1&passive=1209600&ignoreShadow=0&acui=0#identifier")
    if err != nil {
        log.Fatal(err)
    }
    fmt.Println(resp.Cookies())

    s := ".google.com"
    u, err := url.Parse(s)
    fmt.Println(client.Jar.Cookies(u))

}

The response is a blank array but I can see that there are cookies being set. How do I view the contents of a cookieJar in Golang?
