使用fastify-swagger指定可选的'object‘参数

const fastify = require('fastify');
const fastifySwagger = require('fastify-swagger');
const Joi = require('joi');

const app = fastify();

// 注册fastify-swagger插件
app.register(fastifySwagger, {
  routePrefix: '/documentation',
  swagger: {
    info: {
      title: 'API Documentation',
      description: 'API Documentation using fastify-swagger',
      version: '1.0.0',
    },
    externalDocs: {
      url: 'https://swagger.io',
      description: 'Find more info here',
    },
    consumes: ['application/json'],
    produces: ['application/json'],
  },
  exposeRoute: true,
});

// 定义API路由
app.get('/api/user', {
  schema: {
    querystring: Joi.object({
      name: Joi.string().required(),
      age: Joi.number().integer().min(18).max(99),
      address: Joi.object({
        city: Joi.string().required(),
        street: Joi.string().required(),
        zip: Joi.string().length(6),
      }).optional(),
    }),
    response: {
      200: {
        type: 'object',
        properties: {
          message: { type: 'string' },
        },
      },
    },
  },
  handler: async (request, reply) => {
    // 处理请求逻辑
    reply.send({ message: 'Hello, World!' });
  },
});

// 启动服务器
app.listen(3000, (err) => {
  if (err) {
    console.error(err);
    process.exit(1);
  }
  console.log('Server is running on port 3000');
});
