jason web token code example

Example 1: jwt

let jwt = require('jsonwebtoken');

const SUPER_SECRET_TOKEN = "My_Secret_Token";

server.post('/',(req,res)=>{
    res.setHeader('Content-Type', 'application/json');
    var token = jwt.sign({message: "Hello"}, SUPER_SECRET_TOKEN, { expiresIn: '5m' , noTimestamp: true });
    var result = jwt.verify(token, SUPER_SECRET_TOKEN);
    res.end(JSON.stringify({error: false, data: result}));
});

Example 2: what is jsonwebtoken

JSON Web Token is an Internet standard for creating data with optional
signature and/or optional encryption whose payload holds JSON that asserts
some number of claims.

The tokens are signed either using a private secret or a public/private key.

Example 3: jwt

HMACSHA256(
  base64UrlEncode(header) + "." +
  base64UrlEncode(payload),
  
) secret base64 encoded

Example 4: jwt encode

jwt.encode( { 'client_id':'value', 'expires_in':'datetime'}, SECRET_KEY, algorithm='HS256' )

OBS:
Convert datetime to string because in the backend is a json encode system 
and it will generate a TypeError
ex: TypeError: Object of type datetime is not JSON serializable

Example 5: jsonwebtoken

RSASHA256(
  base64UrlEncode(header) + "." +
  base64UrlEncode(payload),
  ,
  
)
