How to send JSON Web Token (JWT Token) as header with Postman and golang


func ProtectedEndpoint(w http.ResponseWriter, req *http.Request) {
params := req.URL.Query()
token, _ := jwt.Parse(params["token"][0], func(token *jwt.Token) (interface{}, error) {
if _, ok := token.Method.(*jwt.SigningMethodHMAC); !ok {
return nil, fmt.Errorf("There was an error")
}
return []byte("secret"), nil
})
if claims, ok := token.Claims.(jwt.MapClaims); ok && token.Valid {
var user User
mapstructure.Decode(claims, &user)
json.NewEncoder(w).Encode(user)
} else {
json.NewEncoder(w).Encode(Exception{Message: "Invalid authorization token"})
}
}

func CreateTokenEndpoint(w http.ResponseWriter, req *http.Request) {
var user User
_ = json.NewDecoder(req.Body).Decode(&user)
token := jwt.NewWithClaims(jwt.SigningMethodHS256, jwt.MapClaims{
"username": user.Username,
})
tokenString, error := token.SignedString([]byte("secret"))
if error != nil {
fmt.Println(error)
}
json.NewEncoder(w).Encode(JwtToken{Token: tokenString})
}
