使用单个express应用程序实现多个swaggerUi

npm install swagger-ui-express swagger-jsdoc

const express = require('express');
const swaggerUi = require('swagger-ui-express');
const swaggerJsdoc = require('swagger-jsdoc');

const app = express();

const swaggerOptions = {
  definition: {
    openapi: '3.0.0',
    info: {
      title: 'API Documentation',
      version: '1.0.0',
      description: 'API documentation using Swagger',
    },
    servers: [
      {
        url: 'http://localhost:3000',
      },
    ],
  },
  apis: ['./routes/*.js'], // 指定包含Swagger注释的路由文件路径
};

const swaggerSpec = swaggerJsdoc(swaggerOptions);

app.get('/swagger.json', (req, res) => {
  res.setHeader('Content-Type', 'application/json');
  res.send(swaggerSpec);
});

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

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});
