如何使用fastify-cors让一个api跨域？

npm install fastify fastify-cors

const fastify = require('fastify');
const fastifyCors = require('fastify-cors');

const app = fastify();
app.register(fastifyCors);

app.register(fastifyCors, {
  origin: true, // 允许所有来源的请求
  methods: ['GET', 'PUT', 'POST'] // 允许的HTTP方法
});

app.get('/api/data', (req, res) => {
  // 处理GET请求的逻辑
});

app.post('/api/data', (req, res) => {
  // 处理POST请求的逻辑
});

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