Go HTTP Post and use Cookies

Question

I'm trying to use Go to log into a website and store the cookies for later use.

Could you give example code for posting a form, storing the cookies, and accessing another page using the cookies?

I think I might need to make a Client to store the cookies, by studying http://gotour.golang.org/src/pkg/net/http/client.go

package main  import ("net/http"         "log"         "net/url"         )  func Login(user, password string) string {         postUrl := "http://www.pge.com/eum/login"          // Set up Login         values := make(url.Values)         values.Set("user", user)         values.Set("password", password)          // Submit form         resp, err := http.PostForm(postUrl, values)         if err != nil {                 log.Fatal(err)         }         defer resp.Body.Close()          // How do I store cookies?         return "Hello" }  func ViewBill(url string, cookies) string {  //What do I put here?  }

Go 1.1 introduced a cookie jar implementation net/http/cookiejar.

import (     "net/http"     "net/http/cookiejar" )  jar, err := cookiejar.New(nil) if err != nil { // error handling }  client := &http.Client{     Jar: jar, }
