I'm using Angular to connect RestAPI. I got an error
zone.js:2969 Access to XMLHttpRequest at 'localhost:8000/auth/api/authen' from origin 'http://localhost:4200' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https.
But this is my POSTMAN result,
Here is my Nodejs code
const express = require('express');
const app = express();
const bodyParser = require('body-parser');
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());
var port = process.env.PORT || 8000;
var router = express.Router();
app.all('*', function(req, res, next) {
res.header('Access-Control-Allow-Origin', '*');
res.header('Access-Control-Allow-Methods', 'DELETE, HEAD, GET, OPTIONS, POST, PUT');
res.header('Access-Control-Allow-Headers', 'Content-Type');
next();
});
app.use('/', router);
router.get('/api', function(req, res, next) {
res.json({ message: 'hello' });
});
router.post('/auth/api/authen', function(req, res, next){
res.json({
success : true,
result : req.body
});
});
// START THE SERVER
app.listen(port);
console.log('Magic happens on port ' + port);private options = { headers: new HttpHeaders().set('Content-Type', 'application/json') }
login(username:string, password:string, ipaddress:string ) : Observable<any> {
return this.http.post<any>( this.baseUrl + '/auth/api/authen', { username, password, ipaddress }, this.options )
.pipe(
map(res => {
console.log(res);
return res;
})
);
}Everything seems very simple but I cannot send a request from Angular app to the server. Please help.
Thanks.

The error tells that, for some reason, request has been sent as localhost:8000/auth/api/authen, which is not supported for protocol schemes:
zone.js:2969 Access to XMLHttpRequest at 'localhost:8000/auth/api/authen' from >origin 'http://localhost:4200' has been blocked by CORS policy: Cross origin >requests are only supported for protocol schemes: http, data, chrome, chrome->extension, https.
If you change your request to http://localhost:8000/auth/api/authen, this error disappears.

In Your Node application you need to enable CORS, As it is clear in the error Request is being blocked by CORS issue, So just these lines of code -
var cors = require('cors')
var app = express()
app.use(cors());
This will enable your HTTP request for any domain, you can customise origin list as per your requirements.

Actually, both @Pardeep Jain & @vadi are right.
You should try CORS first https://expressjs.com/en/resources/middleware/cors.html then change your URL request to back-end from localhost:3000/auth/api/authen to http://localhost:3000/auth/api/authen.
Just in case your Options request has blocked, should be config it by the link above.
