JWT

Usage

$ go get github.com/nilslice/jwt

package jwt provides methods to create and check JSON Web Tokens. It only implements HMAC 256 encryption and has a very small footprint, ideal for simple usage when authorizing clients

package main

import (
	auth "github.com/nilslice/jwt"
	"fmt"
	"net/http"
	"strings"
)

func main() {
	http.HandleFunc("/auth/new", func(res http.ResponseWriter, req *http.Request) {
		claims := map[string]interface{}{"exp": time.Now().Add(time.Hour * 24).Unix()}
		token, err := auth.New(claims)
		if err != nil {
			http.Error(res, "Error", 500)
			return
		}
		res.Header().Add("Authorization", "Bearer "+token)

		res.WriteHeader(http.StatusOK)
	})

	http.HandleFunc("/auth", func(res http.ResponseWriter, req *http.Request) {
		userToken := strings.Split(req.Header.Get("Authorization"), " ")[1]

		if auth.Passes(userToken) {
			fmt.Println("ok")
		} else {
			fmt.Println("no")
		}
	})

	http.ListenAndServe(":8080", nil)
}
