POST AJAX request denied - CORS?

Question

I have setup CORS on my node.js server on port 5000 as follows:

var app = express();

app.use(cors()); //normal CORS
app.options(\'*\', cors()); //preflight         


        

Answer 1

This is the code I am using. It is located in my app.js file

app.all("/*", function (req, res, next) {

  res.header("Access-Control-Allow-Origin", req.headers.origin);
  res.header("Access-Control-Allow-Credentials",true);
  res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE,OPTIONS');
  res.header('Access-Control-Allow-Headers', 'Content-Type,Accept,X-Access-Token,X-Key,Authorization,X-Requested-With,Origin,Access-Control-Allow-Origin,Access-Control-Allow-Credentials');
  if (req.method === 'OPTIONS') {
    res.status(200).end();
  } else {
    next();
  }
});
