Question

Answer 1

Try using the cors in you app middleware

app.use(cors());

Answer 2

This might be related to chrome issue if your cordova is using chrome as a default browser of webview. I've encounter the issue on v76.0.3809.89 of chrome and updating to v76.0.3809.111 solved the Access-Control-Allow-Origin issue.

Answer 3

    app.use(function(req, res, next) {
    res.header("Access-Control-Allow-Origin", "*");
    res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
    next();
});

You can use like this also , may be it will help.

Answer 4

You need to add the whitelist plugin,

https://github.com/apache/cordova-plugin-whitelist

In config.xml add

<!-- will not stop any calls -->
<access origin="*" />
