According to documentation, https://github.com/auth0/node-jsonwebtoken#jwtverifytoken-secretorpublickey-options-callback, jwt.verify will returns decode payload, I run the simple script:
var token = jwt.sign({email: req.body.email,}, 's3cr3t');
var decoded = jwt.verify(token, 's3cr3t');
console.log(decoded)
but it only output like: { iat: 1470725598 }
I expect the output should be like {email: [email protected],}
Is there something I am missing ?
I was not able to mimic your problem until I set the property req.body.email to undefined.
Example:
var jwt = require('jsonwebtoken');
var token = jwt.sign({email: undefined}, 's3cr3t');
var decoded = jwt.verify(token, 's3cr3t');
With it been undefined, the output would look like this;
{ iat: 1470727340 }
and this matches exactly what you were having which cause me to suspect your main issue was just with the property req.body.email been undefined.
Assuming req.body.email is correctly set to "[email protected]" then the output would be;
{ email: '[email protected]', iat: 1470727500 }
Just a side note here. You might want to consider wrapping the .verify method inside a try-catch clause, as shown in the documentation. This is useful for verifying and throwing error when a token is invalid.
