如何运行N个请求，如果有成功使用其结果

async function fetchFirstSuccessfulResponse(urls) {
  const promises = urls.map(url => fetch(url).then(response => response.json()).catch(() => null));
  for (const promise of promises) {
    try {
      const result = await promise;
      if (result !== null) {
        return result; // 返回第一个成功的响应结果
      }
    } catch (error) {
      console.error('Request failed:', error);
    }
  }
  throw new Error('All requests failed'); // 如果所有请求都失败，抛出错误
}

// 示例使用
const urls = [
  'https://api.example.com/data1',
  'https://api.example.com/data2',
  'https://api.example.com/data3'
];

fetchFirstSuccessfulResponse(urls)
  .then(result => console.log('First successful response:', result))
  .catch(error => console.error('Error:', error));
