設置后，一個簡單的有很多關聯，其中用戶 has_many posts 創建一個帶有用戶 ID 的帖子似乎有必要解析 jwt Claims 以獲取 userID 并將其放置在帖子創建中。那么，如何從 jwt Claims 獲取用戶 ID我嘗試解析令牌但只是出現map[email:[email protected] exp:1.655701949e+09 username:teste]tokenString := c.GetHeader("Authorization") //claims := jwt.MapClaims{}token, err := jwt.ParseWithClaims(tokenString, claims, func(token *jwt.Token) (interface{}, error) { return []byte("supersecretkey"), nil})if claims, ok := token.Claims.(jwt.MapClaims); ok && token.Valid { fmt.Printf("%v", claims )} else { fmt.Println(err)}

我從一開始就告訴過你，當你想生成 JWT 時，請執行以下操作：
token := jwt.New(jwt.SigningMethodHS256)
// Set claims
// This is the information which frontend can use
// The backend can also decode the token and get admin etc.
claims := token.Claims.(jwt.MapClaims)
claims["username"] = ID
accessTokenExpireTime := time.Now().Add(time.Hour * 48).Unix()
claims["exp"] = accessTokenExpireTime
// Generate encoded token and send it as response.
// The signing string should be secret (a generated UUID works too)
t, err := token.SignedString([]byte("AccessToken"))
然后當你想解碼用戶名時，請執行以下操作：
type MyCustomClaims struct {
Username string `json:"username"`
jwt.StandardClaims
}
auth := c.Request.Header.Get("Authorization")
if auth == "" {
c.AbortWithStatusJSON(http.StatusUnauthorized, gin.H{"Message": "Authorization Header Not Found"})
return
}
splitToken := strings.Split(auth, "Bearer ")
auth = splitToken[1]
token, err := jwt.ParseWithClaims(auth, &MyCustomClaims{}, func(token *jwt.Token) (interface{}, error) {
return []byte("AccessToken"), nil
})
if err != nil {
c.AbortWithStatusJSON(http.StatusUnauthorized, gin.H{"Message": "Token is wrong or Expire"})
return
}
if claims, ok := token.Claims.(*MyCustomClaims); ok && token.Valid {
log.Printf("%v %v", claims.Username, claims.StandardClaims.ExpiresAt)
}
