英文:
r.Request.cookie() not working and if I use r.Response.request() it panic
问题
首先，我不知道最近的Go更新是否不再与r.Request.Cookie()函数一起使用，但似乎这个函数不再存在了。
所以我找到了r.Response.Request.Cookie()，但是一旦我打开页面，它就崩溃了。
这是我的代码：
package main
import (
"io"
"log"
"net/http"
uuid "github.com/nu7hatch/gouuid"
)
func main() {
r := http.NewServeMux()
r.HandleFunc("/", index)
http.ListenAndServe(":80", r)
}
func index(w http.ResponseWriter, req *http.Request) {
c, err := req.Response.Request.Cookie("session-id")
if err != nil {
cid, _ := uuid.NewV4()
c := &http.Cookie{
Name: "session-id",
Value: cid.String(),
}
http.SetCookie(w, c)
}
log.Fatal(err)
io.WriteString(w, c.String())
}
希望对你有帮助！

First I don't know if recent updates of go doesn't work anymore with r.Request.Cookie() but it seems that this func doesn't exist anymore...
So I came across r.Response.Request.Cookie() but as soon as I open the page it crash.
This is my code:
package main
import (
"io"
"log"
"net/http"
uuid "github.com/nu7hatch/gouuid"
)
func main() {
r := http.NewServeMux()
r.HandleFunc("/", index)
http.ListenAndServe(":80", r)
}
func index(w http.ResponseWriter, req *http.Request) {
c, err := req.Response.Request.Cookie("session-id")
if err != nil {
cid, _ := uuid.NewV4()
c := &http.Cookie{
Name: "session-id",
Value: cid.String(),
}
http.SetCookie(w, c)
}
log.Fatal(err)
io.WriteString(w, c.String())
}

在c, err := req.Response.Request.Cookie("session-id")中，Request将为nil，因为它已经被使用过了，你可以直接使用req.Cookie("cookie-name")。
英文:
In c, err := req.Response.Request.Cookie("session-id") The Request will be nil as it's already consumed, You can go with req.Cookie("cookie-name") directly.

我正在为你提供中文翻译，以下是翻译好的内容：
我观看的教程可能已经过时了。更新后的可用代码如下：
cookie, err := req.Cookie("session-id")
if err == http.ErrNoCookie {
c := &http.Cookie{
Name: "session-id",
Value: cid.String(),
MaxAge: 300,
HttpOnly: true,
}
感谢所有回答的人。
英文:
The tutorial I was whatching was likely outdated. The updated working code is:
cookie, err := req.Cookie("session-id")
if err == http.ErrNoCookie {
c := &http.Cookie{
Name: "session-id",
Value: cid.String(),
MaxAge: 300,
HttpOnly: true,
}
