i trying create go cookie. want assign id mongodb stored in cookie. while compiling getting error follows:-

"unknown http.cookie field 'id' in struct literal"

the following code:-

getuser := user.checkdb() expiration := time.now().add(365 * 24 * time.hour)  //the error caused next line cookie := http.cookie{id: getuser[0].id, name: getuser[0].email, value: getuser[0].password, expires: expiration} http.setcookie(w, &cookie)    func (this *user) checkdb() []user {     var results []user     sess, db := getdatabase()     defer sess.close()     c := db.c("user")     uname := &this.email     err := c.find(bson.m{"email": *uname}).sort("-id").all(&results)     if err != nil {         panic(err)     } else {         fmt.println("results all: ", results)         return results     } }  type cookie struct {     id         bson.objectid `bson:"_id,omitempty"`     name       string     value      string     path       string     domain     string     expires    time.time     rawexpires string     maxage     int     secure     bool     httponly   bool     raw        string     unparsed   []string } 

thanks in advance.

here solution problem.

cookie struct below:

type cookie struct {         name       string     value      string     path       string     domain     string     expires    time.time     rawexpires string     maxage   int     secure   bool     httponly bool     raw      string     unparsed []string } 

cookie creation

 value := map[string]string{         "id": cookieid,     }     if encoded, err := ckiehandler.encode("session", value); err == nil {         cookie := &http.cookie{         name:  "session",         value: encoded,         path:  "/",         }         http.setcookie(response, cookie)     } 

cookie call

if cookie, err := request.cookie("session"); err == nil {         cookievalue := make(map[string]string)         if err = ckiehandler.decode("session", cookie.value, &cookievalue); err == nil {             id = cookievalue["id"] // **pass bson id here**         }     }
