在swagger-ui-express中如何解决CORS问题

Question

I'm getting "Possible cross-origin (CORS) issue?" error for Spec2 when run this swagger-ui-express app:

const express = require('express');
var cors = require('cors');
const app = express();
const swaggerUi = require('swagger-ui-express');

var options = {
  explorer: true,
  swaggerOptions: {
    urls: [
      {
        url: 'http://petstore.swagger.io/v2/swagger.json',
        name: 'Spec1'
      },
      {
        url: 'http://xxx.xxx.xxx.xxx:xxxxx/swagger.json',
        name: 'Spec2'
      }
    ]
  }
}

app.use('/api-docs', swaggerUi.serve, swaggerUi.setup(null, options));

app.listen(8080, () => console.log(`Listening on port 8080!`))

Neither app.use(cors()) nor app.use(swaggerUi.cors()) helps. How can it be fixed?
