Why this promisified JWT.verify isn't working?-CodePudding

So I'm trying to promisify jwt.verify manually but for some reason it is not passing the decoded_token to the resolve function.

This is working fine...

This isn't..

PromisifiedJWTVerify.. Can someone please mention the cause of this behavior?

CodePudding user response：

you need to use invoke resolve() like that on jwt.verify(token, secret, resolve), when you just do resolve you aren't invoking it, you're referencing it.

edit: Screw my answer above I think it's supposed to be like this

jwt.verify(token, secret, (err, data) => {
  if (err) return reject(err);
  return resolve(data);
});

this is because the first parameter passed in the callback is the error, which you don't want to put in the resolve but in the reject while the second parameter is the actual data which in case you actually do want in resolve
