如何解决swagger-ui-express中CORS问题

const express = require('express');
const cors = require('cors');
const swaggerUi = require('swagger-ui-express');
const swaggerDocument = require('./swagger.json');

const app = express();
app.use(cors()); // 使用CORS中间件

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

app.listen(3000, () => {
  console.log('Swagger UI is running on http://localhost:3000/api-docs');
});

const express = require('express');
const swaggerUi = require('swagger-ui-express');
const swaggerDocument = require('./swagger.json');

const app = express();

const swaggerUiOptions = {
  swaggerOptions: {
    url: 'http://api.example.com/swagger.json', // 将API请求转发到目标服务器
  },
};

app.use('/api-docs', swaggerUi.serve, swaggerUi.setup(swaggerDocument, swaggerUiOptions));

app.listen(3000, () => {
  console.log('Swagger UI is running on http://localhost:3000/api-docs');
});
