Generate signed JWT token string in Golang

README.md

Import the JWT package

import "github.com/dgrijalva/jwt-go"

Then generate with NewWithClaims.

Finally, get the signed JWT token string by calling SignedString().

main.go

package main

import (
	"fmt"
	jwt "github.com/dgrijalva/jwt-go"
	"log"
	"time"
)

const (
	ApiKey = "123123123"
	ApiSecret = "secret"
)

func main() {
	token := jwt.NewWithClaims(jwt.SigningMethodHS256, jwt.MapClaims{
		"iat": time.Now().Unix(),
		"sub": ApiKey,
	})
	if token == nil {
		log.Fatal("error generating token")
		return
	}

	tokenString, err := token.SignedString([]byte(ApiSecret))
	if err != nil {
		log.Fatal("error signing token")
		return
	}

	fmt.Println("Generated JWT token string: " + tokenString)
}
