如何在 golang 中保存会话
How to save a session in golang
我正在尝试使用大猩猩会话和 securecookie 在我的 golang 后端中保存已登录的用户 ID。
这是我的打包会话:
package session
import (
"fmt"
"net/http"
"github.com/gorilla/securecookie"
"github.com/gorilla/sessions"
)
var store = sessions.NewCookieStore(securecookie.GenerateRandomKey(32))
//GetSessionLoggedID returns loggedID
func GetSessionLoggedID(r *http.Request) int {
storeAuth, _ := store.Get(r, "authentication")
if auth, ok := storeAuth.Values["loggedID"].(bool); ok && auth {
return storeAuth.Values["loggedID"].(int)
}
fmt.Println("none found")
return 0
}
//SetSessionLoggedID sets cookie session user ID
func SetSessionLoggedID(w http.ResponseWriter, r *http.Request, id int) {
storeAuth, err := store.Get(r, "authentication")
if err != nil {
fmt.Println(err.Error())
}
storeAuth.Options = &sessions.Options{HttpOnly: true, Secure: true, MaxAge: 2628000, Path: "/"}
storeAuth.Values["loggedID"] = id
storeAuth.Save(r, w)
}
我有另一个包可以验证登录用户的电子邮件/密码。
函数如下:
func (handler *UserHandler) checkPassword(w http.ResponseWriter, r *http.Request) {
var body struct {
Email string
Password string
}
err := json.NewDecoder(r.Body).Decode(&body)
if err != nil {
http.Error(w, err.Error(), http.StatusInternalServerError)
return
}
loggedID, err := handler.UserUsecase.PasswordMatch(body.Email, body.Password)
if err != nil || loggedID == 0 {
http.Error(w, "Could not authenticate user", http.StatusUnauthorized)
return
}
session.SetSessionLoggedID(w, r, loggedID)
json.NewEncoder(w).Encode(struct {
ID int `json:"id"`
}{loggedID})
}
返回的ID是正确的。但是会话没有像我希望的那样保存。
如果我在 checkpassword 函数末尾添加 session.GetSessionLoggedID(r)
,我会得到 "none found"。
我错过了什么?
// watch this line
if auth, ok := storeAuth.Values["loggedID"].(bool); ok && auth {
storeAuth.Values["loggedID"]
不是 bool
,所以 ok
是 false
,那么你得到 "none found"
改为
if auth, ok := storeAuth.Values["loggedID"]; ok{
return auth.(int)
}
fmt.Println("none found")
