如何在Next.js中进行依赖fetch接口调用

npm install isomorphic-unfetch

import fetch from 'isomorphic-unfetch';

async function handleSubmit(event) {
  event.preventDefault();
  const response = await fetch('/api/my-endpoint', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({ data: 'example' }),
  });
  const data = await response.json();
  console.log(data);
}

export default function handler(req, res) {
  if (req.method === 'POST') {
    const { data } = req.body;
    // 处理你的接口逻辑
    res.status(200).json({ message: '接口调用成功', data });
  } else {
    res.status(405).json({ message: '只支持POST请求' });
  }
}
