Setting up Cookies at browser : Golang
问题
作为一个在Golang上的新手，我试图在浏览器上设置cookies，我有一个简单的基本代码，但它根本不起作用，我做了一些搜索并找到了一些stackoverflow的例子，但仍然没有找到正确的方法。
创建了一个简单的hello.go文件：
package main
import "io"
import "net/http"
import "time"
func handler(w http.ResponseWriter, req *http.Request) {
expire := time.Now().AddDate(0, 0, 1)
cookie := http.Cookie{"test", "tcookie", "/", "www.dummy.com", expire, expire.Format(time.UnixDate), 86400, true, true, "test=tcookie", []string{"test=tcookie"}}
req.AddCookie(&cookie)
io.WriteString(w, "Hello world!")
}
func main() {
http.HandleFunc("/", handler)
}
但是如预期的那样，我遇到了错误，如\hello.go:9:15: composite struct literal net/http.Cookie with untagged fields。
请问有人可以给我建议或者给我一个详细的设置cookies的基本示例吗？
我在stackoverflow上进行了一些搜索并找到了以下链接：https://stackoverflow.com/questions/12130582/setting-cookies-in-golang-net-http/12130619#12130619，但是我无法正确理解它。
谢谢。

As am newbie here on Golang, trying to setup cookies at browser,
have simple basic code but it doesn't working at all & did some googling & found some stackoverflow ex. but still not picking up the right way.
Created a simple hello.go
package main
import "io"
import "net/http"
import "time"
func handler(w http.ResponseWriter, req *http.Request) {
expire := time.Now().AddDate(0, 0, 1)
cookie := http.Cookie{"test", "tcookie", "/", "www.dummy.com", expire, expire.Format(time.UnixDate), 86400, true, true, "test=tcookie", []string{"test=tcookie"}}
req.AddCookie(&cookie)
io.WriteString(w, "Hello world!")
}
func main() {
http.HandleFunc("/", handler)
}
But as expected here am facing error's like \hello.go:9:15: composite struct literal net/http.Cookie with untagged fields
Could any one please suggest me or give me basic example (in detailing) for setting up cookies.
Had few searches on SO and found..
https://stackoverflow.com/questions/12130582/setting-cookies-in-golang-net-http/12130619#12130619 but not able to picking up this properly..
Thanks.

好的，以下是翻译好的部分：
在你提供的问题中，基本上是建议使用net/http中的这个函数：
func SetCookie(w ResponseWriter, cookie *Cookie)
所以在你的例子中，不要写
req.AddCookie(&cookie)
而应该写成
http.SetCookie(w, &cookie)
英文:
Well in the question you link to it basically says to use this function from net/http:
func SetCookie(w ResponseWriter, cookie *Cookie)
So in your example instead of writing
req.AddCookie(&cookie)
you should write this
http.SetCookie(w, &cookie)

得分: 6
cookie := &http.Cookie{Name:"test", Value:"tcookie", Expires:time.Now().Add(356*24*time.Hour), HttpOnly:true}
after this
change
req.AddCookie(&cookie)
to
http.SetCookie(w, cookie)
and finally because your application is running on Google App Engine change:
func main()
to
func init()
英文:
cookie := http.Cookie{"test", "tcookie", "/", "www.dummy.com", expire, expire.Format(time.UnixDate), 86400, true, true, "test=tcookie", []string{"test=tcookie"}}
should be something like this:
cookie := &http.Cookie{Name:"test", Value:"tcookie", Expires:time.Now().Add(356*24*time.Hour), HttpOnly:true}
after this
change
req.AddCookie(&cookie)
to
http.SetCookie(w, cookie)
and finally because your application is running on Google App Engine change:
func main()
to
func init()
