Passport JWT Strategy extracting options

Question

Using Passport JWT Strategy, I'm passing the token down via params, and extracting the token like this ExtractJWT.fromUrlQueryParameter('secret_token').

But sometimes I'm passing the token down via header, I would like to extract it like this ExtractJWT.fromHeader('secret_token').

How can I check how its being passed down and use the correct extracting method dynamically.

This is my code:

passport.use(new JWTstrategy({
  secretOrKey: process.env.AUTH_SECRET,
  jwtFromRequest: ExtractJWT.fromUrlQueryParameter('secret_token')

}, async (token, done) => {
  try {
    //Pass the user details to the next middleware
    return done(null, token.user);
  } catch (error) {
    done(error);
  }
}));

Thank you! Im on this for a long time....

Use ExtractJwt.fromExtractors() method

var jwtStrategy = new JwtStrategy({
// this will try to extract from Query parm, header and Authheader
  jwtFromRequest: ExtractJwt.fromExtractors([ExtractJwt.fromUrlQueryParameter("secret_token"), ExtractJwt.fromHeader("secret_token"), ExtractJwt.fromAuthHeaderAsBearerToken()]),
//here we have defined all possible extractors in an array
  secretOrKey: process.env.AUTH_SECRET
}, async (payload, done) => {
  ...
});
