在.then()链中间重试fetch()调用

function retryFetch(url, options, retries = 3) {
  return fetch(url, options)
    .then(response => {
      if (!response.ok) {
        throw new Error('Network response was not ok');
      }
      return response.json();
    })
    .catch(error => {
      if (retries > 0) {
        console.log(`Request failed, retrying... (${retries} retries left)`);
        return retryFetch(url, options, retries - 1);
      }
      throw error;
    });
}

// 使用示例
retryFetch('https://api.example.com/data', { method: 'GET' })
  .then(data => {
    // 处理请求成功的响应数据
    console.log(data);
  })
  .catch(error => {
    // 处理请求失败的情况
    console.error(error);
  });
