Token in header (cURL) with Express.js Node.js

Question

Token in header (cURL) with Express.js Node.js

So, I want to use this code in my project:

var allowCrossTokenHeader = function(req, res, next) {
    res.header("Access-Control-Allow-Headers", "token");
};

But it does not work, the server hangs and does not work, if I comment this code the server is working correctly. I need to check a token in each request to my RESTful api, any idea how to do?

node.js
rest
curl
express
restful-authentication

You need to call next() for it to continue to the next middleware in the stack.

var allowCrossTokenHeader = function(req, res, next) {
    res.header("Access-Control-Allow-Headers", "token");
    next();
};

If the current middleware does not end the request-response cycle, it must call next() to pass control to the next middleware, otherwise the request will be left hanging.
