I am calling nodeJS REST API running on different localhost into an angular app,
in postman I get the expected result. but in angular application it is falling due to 403 error, It is happening because of preflight( Response for preflight has invalid HTTP status code 403). I tried to remove some default headers using $httpprovider and also tried to use proper server name instead of wildcard(*) in access-control-allow-region nothing worked.Looking for help!
There is no Authentication for preflight requests.

2If you trying to resolve it using Angular, nothing going to help you. It need to fixed server side. It is `CORS` issue.` – Ved Sep 29 '17 at 11:07

By handling OPTIONS request at server side i am able to solve the problem, This post solved my problem
By adding following line of code
app.use(function (req,res,next){
if (req.method === 'OPTIONS') {
console.log('!OPTIONS');
var headers = {};
// IE8 does not allow domains to be specified, just the *
// headers["Access-Control-Allow-Origin"] = req.headers.origin;
headers["Access-Control-Allow-Origin"] = "*";
headers["Access-Control-Allow-Methods"] = "POST, GET, PUT, DELETE, OPTIONS";
headers["Access-Control-Allow-Credentials"] = false;
headers["Access-Control-Max-Age"] = '86400'; // 24 hours
headers["Access-Control-Allow-Headers"] = "X-Requested-With, X-HTTP-Method-Override, Content-Type, Accept";
res.writeHead(200, headers);
res.end();
} else {
//...
other requests
}
});
