jwtToken.js

var jwt = require('jsonwebtoken');

module.exports = {
    getJwtToken : function(issuer, secret) {
        var issuedAt = Math.floor(Date.now() / 1000);
        var payload = {
            iss: issuer,
            jti: Math.random().toString(),
            iat: issuedAt,
            exp: issuedAt + 60,
        };

        var token = jwt.sign(payload, secret, {
            algorithm: 'HS256',
        });
