I am trying to make a payment using paypal sdk. My front end is angularjs and my back end is nodejs.
In my front end, I just call a route in my node server as:
$http.post('/paypal/pay', cart)
I have CORS configured in my node server.
The CORS problem happens in the "res.redirect" line.
I also configured CORS also into headers from paypal config to try solve the problem, but no success.
I am testing paypal payment using nodejs in localhost.
When I try to make a payment I get the next error:
What am I doing wrong?
//error
https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token=EC-YYYYYY: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost' is therefore not allowed access.
//node server
const express = require('express');
const app = express();
const PaypalAPI=require('./routes/paypal-checkout');
app.all('*', function(req, res, next) {
res.setHeader('Access-Control-Allow-Origin', '*');
res.setHeader('Access-Control-Allow-Methods', 'PUT, GET, POST, DELETE, OPTIONS');
res.setHeader('Access-Control-Allow-Headers', 'Content-Type, Authorization');
next();
});
app.use('/paypal',PaypalAPI)
var server = app.listen(app.get('port'), function () {
console.log('Servidor rodando em ' +app.get('host') + ' Porta: '+app.get('port'));
});
//node router - paypal-checkout.js
const express = require('express');
const paypal = require('paypal-rest-sdk');
const router = express.Router();
paypal.configure({
'mode': 'sandbox', //sandbox or live

'client_secret': 'YYYYYY',
'headers' : {
'Access-Control-Allow-Origin': '*',
'Access-Control-Allow-Methods': 'PUT, GET, POST, DELETE, OPTIONS',
'Access-Control-Allow-Headers': 'Content-Type, Authorization'
}
});
router.post('/pay', (req, res) => {
const create_payment_json = {

}]
},

}]
};
paypal.payment.create(create_payment_json, function (error, payment) {
if (error) {
throw error;
} else {
for(let i = 0;i < payment.links.length;i++){
if(payment.links[i].rel === 'approval_url'){
res.redirect(payment.links[i].href);
}
}
}
});
});
