使用net / http设置cookie

Question

我正在尝试使用Go的net / http包设置cookie。我有：package mainimport "io"import "net/http"import "time"func indexHandler(w http.ResponseWriter, req *http.Request) {    expire := time.Now().AddDate(0, 0, 1)    cookie := http.Cookie{"test", "tcookie", "/", "www.domain.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("/", indexHandler)    http.ListenAndServe(":80", nil)}我尝试将“ Golang”与“ cookies”进行谷歌搜索，但没有得到任何良好的结果。如果有人能指出我正确的方向，将不胜感激。
