Compatibility with Sails

I love this repository and I’m trying to use it in a Sails project.

Express middleware in sails as known as policies and internally sails use express 3.x.

Simply you can define a policies and decide what route request pass for each policies (if is necessary).

The interface for create the policy is the same to create a middleware:

module.exports = function(req, res, next) {
 // do something
};

I want to validate the header token with express-jwt and later do a custom action in the policy (for example, search the user and expose in req.user) I’m not sure how to concatenate the middlewares to get in the more external middleware the callback of the express-jwt.

Just something like this:

var options = {secret: 'seeeecret!'};
var expressjwt = require('express-jwt')({options});

module.exports = function(req, res, next) {
  expressjwt(req, res, function(token){
    // Now I have the token
    // do something
    next();
  });
};

Do you think that is possible?

Thanks!!! works perfect. Actually jsonwebtoken library validate the token, so token parameter is undefined. This works fine:

module.exports = function(req, res, next) {
  return expressjwt(req, res, function(err) {
    if (!err) {
      return next();
    }
    res.status(err.status);
    return res.json(err.inner);
  });
};

so, finally, what about add this in the documentation for future users? 😃

I can not determine a use case where you intend to use a JSON… all time you are passing a token string, right?

no, you can create JWTs where the payload is a JSON, like this:

var jwt = require('jsonwebtoken');
var token = jwt.sign({foo: 'bar'}, secret);

in fact most of the time we use this instead of string.

I’ve fixed this on version v1.3.1.

Please next time create another issue, this issue has been closed already.

Thanks for reporting it
