wish helps you You could try adding a filter class to your java code in the server side, sample code
code :
public class CorsFilter extends OncePerRequestFilter {

@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
    response.addHeader("Access-Control-Allow-Origin", "*");
    if (request.getHeader("Access-Control-Request-Method") != null && "OPTIONS".equals(request.getMethod())) {
        //Add CORS "pre-flight" request
        response.addHeader("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS");
         response.addHeader("Access-Control-Allow-Headers", "Authentication-token");
        response.addHeader("Access-Control-Allow-Headers", "Content-Type");
        response.addHeader("Access-Control-Max-Age", "3600");
    }
    filterChain.doFilter(request, response);
}
<filter>
    <filter-name>cors</filter-name>
    <filter-class>location.of.filter.class</filter-class>
</filter>
<filter-mapping>
    <filter-name>cors</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>
app.config(['$httpProvider', function($httpProvider) {
    $httpProvider.defaults.useXDomain = true;
    delete $httpProvider.defaults.headers.common['X-Requested-With'];
}]);

I wish did fix the issue. Download the Allow-Control-Allow-Origin application from google chrome. Enable the CORS in the application installed and execute your code. This will temporarily allow the CORS in your browser.

help you fix your problem Simply use cors module of express and you will be fine:
code :
var express = require('express')
var cors = require('cors')
var app = express()

app.use(cors())
