app.all('*', function(req, res, next) { res.header('Access-Control-Allow-Origin', '*'); res.header('Access-Control-Allow-Headers', 'Content-Type, Content-Length, Authorization, Accept, X-Requested-With , yourHeaderFeild'); res.header('Access-Control-Allow-Methods', 'PUT, POST, GET, DELETE, OPTIONS'); if (req.method == 'OPTIONS') { res.send(200); } else { next(); }});
