Hi good afternoon golang dev's, I'm starting in golang blogs and I don't
where to post this kind of questions,
Learning fiber framework and JWT Auth I'm getting in the register Func and
Login Func the user Id is saving correctly on DB. The cookie and JWT are
getting correctly and disply the cookie and preseve on the frontEnd, but
when I want to get the login UserId on Controller I got 0 did some one
know's what is happening?
I leave the code hopping have some orientation.
Jwt has been updated and I’m confuse.
```
// Midleware:
const SecretKey = "secret"
func IsAuthenticated(c *fiber.Ctx) error {
cookie := c.Cookies("jwt")
token, err := jwt.ParseWithClaims(cookie, &jwt.RegisteredClaims{},
func(token *jwt.Token)
(interface{}, error) {
return []byte(SecretKey), nil
})
if err != nil || !token.Valid {
c.Status(fiber.StatusUnauthorized)
return c.JSON(fiber.Map{
"message": "unauthenticated",
})
}
return c.Next()
}
func GetUserId(c *fiber.Ctx) (uint, error) {
cookie := c.Cookies("jwt")
log.Println("Cookie .........: ", cookie)
token, err := jwt.ParseWithClaims(cookie, &jwt.RegisteredClaims{},
func(token *jwt.Token)
(interface{}, error) {
return []byte(SecretKey), nil
})
log.Println("Token .........: ", token)
log.Println("Error .........: ", err)
if err != nil {
return 0, err
}
// var user dto.User
// expireTime := time.Now().Add(24 * time.Hour)
// payloads := jwt.RegisteredClaims{
// Subject: strconv.Itoa(int(user.Id)),
// ExpiresAt: &jwt.NumericDate{Time: expireTime},
// }
payload := token.Claims.(*jwt.RegisteredClaims)
id, _ := strconv.Atoi(payload.Subject)
return uint(id), nil
}
func GenerateJWT(id uint) (string, error) {
expireTime := time.Now().Add(24 * time.Hour)
var user dto.User
token, err := jwt.NewWithClaims(jwt.SigningMethodHS256,
jwt.RegisteredClaims{
Subject: strconv.Itoa(int(user.Id)),
ExpiresAt: &jwt.NumericDate{Time: expireTime},
}).SignedString([]byte(SecretKey))
if err != nil {
log.Println(err)
}
return token, err
}
//Controller:
func User(c *fiber.Ctx) error {
var user dto.User
id, err := middlewares.GetUserId(c)
log.Println(id)
if err != nil {
return err
}
confmysql.DB.Where("id = ?", id).First(&user)
return c.JSON(user)
}
